IMPORTANT Notice:
DAWN Wireless products are designed to be used in industrial environments, by experienced industrial engineering personnel with adequate knowledge of safety design considerations.
DAWN Wireless radio products are used on unprotected license-free radio bands with radio noise and interference. The products are designed to operate in the presence of noise and interference, however in an extreme
case, radio noise and interference could cause product operation delays or operation failure. Like all industrial
electronic products, DAWN Wireless products can fail in a variety of modes due to misuse, age, or malfunction.
We recommend that users and designers design systems using design techniques intended to prevent personal
injury or damage during product operation, and provide failure tolerant systems to prevent personal injury or
damage in the event of product failure. Designers must warn users of the equipment or systems if adequate
protection against failure has not been included in the system design. Designers must include this Important
Notice in operating procedures and system manuals.
These products should not be used in non-industrial applications, or life-support systems, without consulting
DAWN Wireless first.
• A radio license is not required in some countries, provided the module is installed using the
aerial and equipment configuration described in the M1115NL Installation Guide. Check with
your local distributor for further information on regulations.
• Operation is authorized by the radio frequency regulatory authority in your country on a
non-protection basis. Although all care is taken in the design of these units, there is no
responsibility taken for sources of external interference. Systems should be designed to be
tolerant of these operational delays.
• To avoid the risk of electrocution, the aerial, aerial cable, serial cables and all terminals of
the M1115NL module should be electrically protected. To provide maximum surge and
lightning protection, the module should be connected to a suitable earth and the aerial,
aerial cable, serial cables and the module should be installed as recommended in the In
stallation Guide
• To avoid accidents during maintenance or adjustment of remotely controlled equipment, all
equipment should be first disconnected from the M1115NL module during these adjustments.
Equipment should carry clear markings to indicate remote or automatic operation. E.g.
“This equipment is remotely controlled and may start without warning. Isolate at the switch
board before attempting adjustments.”
• The M1115NL module is not suitable for use in explosive environments without additional
protection.
• The M1115NL operates unlicensed Radio frequencies and proprietary protocols to
communicate over the radio. Nevertheless, if your system is not adequately secured, third
parties may be able to gain access to your data or gain control of your equipment via the
radio link. Before deploying a system make sure you have considered the security aspects
of your installation carefully.

Introduction
11. Overview
The M1115NL range of I/O modules has been designed to provide standard “off-the-shelf” telemetry functions, for an
economic price. Telemetry is the transmission of data or signals over a long distance via radio or twisted-pair wire
cable.
Although the M1115NL Series is intended to be simple in its application, it provides many sophisticated features,
which will be explained in the following chapters.
This manual should be read carefully to ensure that the modules are configured and installed to give reliable performance.
The M1115NL telemetry module extends the functionality provided by the earlier 105U and 905U E-series modules. It
provides on-board I/O via a front mounting 20-way connector and has provision for extra expansion modules (DAWN
Wireless 115S or MODBUS devices) to be connected using a standard RS485 serial connection.
The module can monitor the following types of signals
•
Digital (on/off) signals - Contact Closure or Switch
•
Analog (continuously variable) signals – Tank level, Motor speed, temperature, etc
•
Pulsed signal - Frequency signal – Metering, accumulated total, rainfall, etc
•
Internal Signals – Supply voltage, Supply failure, battery status, etc.
The modules monitor the input signals and transmit the values by radio or Ethernet cabling to another module or modules that have been configured to receive this information.
The M1115NL radio has been designed to meet the requirements of unlicensed operation for remote monitoring and
control of equipment. A radio licence is not required for the M1115NL in many countries.
Input signals that are connected to the module are transmitted and appear as output signals on other modules. A
transmission occurs whenever a “Change-of-State”, “COS” occurs on an input signal. A “Change-of-State” of a digital
or an internal digital input is a change from “off” to “on” or vice-versa.
For an analog input, internal analog input or pulse input rate a “Change-of-State” is a configurable value called “Sensitivity”. The default Sensitivity is 1000 counts (3%) but can be changed in the Sensitivity Block page.
In addition to change-of-state messages, update messages are automatically transmitted on a configurable time basis. This update ensures the integrity of the system.
Pulse inputs counts are accumulated and the total count is transmitted regularly according to the configured update
time.
The M1115NL modules transmit the input/output data using radio or Ethernet. The data frame includes the “address”
of the transmitting module and the receiving module, so that each transmitted message is acted on only by the correct
receiving unit. Each message includes error checking to ensure that no corruption of the data frame has occurred due
to noise or interference. The module with the correct receiving “address” will acknowledge the message with a return
transmission (acknowledgement). If the original module does not receive a correct acknowledgement, it will retry 1 to
5 times (default is 3) before setting the communications fail status of that message. For critical messages, this status
can be reflected on an output on the module for alert purposes. The module will continue to try to establish communications and retry, each time an update, or change-of-state occurs.
A system can be a complex network or a simple pair of modules. An easy-to-use configuration procedure allows the
user to specify any output destination for each input.

Two versions of the M1115NL are available. The Legacy version provides operation with existing DAWN Wireless I/O
devices (905 series and 105 series modules). The second version provides enhanced features, including IP addressing, allowing thousands of modules to exist in a system, and allowing automatic routing of messages through repeater
stations.
Each M1115NL radio can have up to 24 expansion I/O modules (DAWN Wireless 115S) connected by RS485 twisted
pair provided there is sufficient power to power all modules with I/O. Any input signal at any module may be configured
to appear at any output on any module in the entire system.
Modules can be used as repeaters to re-transmit messages on to the destination module. Repeaters can repeat messages on the radio channel or from the radio channel to the serial channel (and serial to radio). Using Legacy protocol,
up to five repeater addresses may be configured for each input-to-output link. The meshing protocol will automatically
select other stations to act as repeaters if required.
The units may be configured via ethernet using a web browser or via USB port and system configuration software. The
web based configuration and software configuration is defined in Chapter 4 - Configuration.
1.2 Module Structure
M1115NL
Figure 1 – Module Structure
The M1115NL is made up of a number of basic sections, which all interface with a central Input and output storage
area (I/O Store).
The I/O Data Store provides storage for I/O data as well as providing services to other processes in the system. The
I/O Store provides eight different blocks of data - two containing input and output bit data, two containing input and
output word data, two containing long-word type data and two containing floating-point data. The two files of each type
in turn support inputs and outputs on the local machine, and data storage for the gateway function of the machine.
These files are mapped into the address map as described below. There are other registers values within the database that can be used for system management - these will be discussed later in this manual.
The Radio Interface allows the M1115NL to communicate with other modules within the system using a proprietary
radio protocol called “WIBMesh”. Messages from other M1115NL modules are received by the radio port and used
to update the input values in the I/O Data Store. The WIBMesh protocol is an extremely efficient protocol for radio
communications. Radio messages can be sent using exception reporting - that is, when there is a change of an input
signal - or by read/write messages. Each message will be comprised of multiple I/O values termed as a “block” of I/O).

There are also update messages, which are sent for integrity purposes. Messages include error checking, with the
destination address sending a return acknowledgment. Up to four attempts are made to transmit the message over
each hop of the radio path, if no acknowledgement is received. The WIBMesh protocol is designed to provide reliable
radio communications on an open license-free radio channel.
The On-Board I/O in the form of - 8 discrete I/O, 2 single ended analog inputs, 2 differential analog inputs, and 2 current sourcing analog outputs. Each discrete I/O can function as either a discrete input (voltage free contact input) or
discrete output (transistor output). Each I/O point is linked to separate I/O registers within the I/O Data Store.
There are also a number of Internal I/O that can be accessed from the I/O Data Store. These inputs can be used to
interpret the status of a single module or an entire system
• Battery voltage – The battery terminal voltage displayed as an Analog value.
• Loop Supply – Monitors the +24V DC Analog Loop Supply (ALS), used to power analog current loops and displays
this as an Analog value.
• Expansion Module Volts – Monitors the Supply voltage of the connected expansion modules, displayed as an
Analog value.
• RSSI – Will indicate the radio signal level for the selectable address, displayed as a dB level. Note: Only available
in Legacy version. Otherwise, refer to Communication diagnostics functions
• Comms Fail – A selectable register can indicate a Communications fail for the selected address. Note: Only avail
able in Legacy version. Otherwise, refer to Communication diagnostics functions
Lastly, the Expansion port, which enables 115S expansion I/O modules to be added to the module. Expansion module
I/O is dynamically added to the I/O of the M1115NL by adding an offset to the address.
1.3 Getting Started
Most applications for the M1115NL require little configuration. The M1115NL has many sophisticated features, however if you do not require these features, this section will allow you to configure the units quickly.
First, read Chapter 2 - , “Installation”, which will go through the power supply, antenna/coax connections and any I/O
connections.
Power the M1115NL and make an Ethernet connection to your PC (refer to Section 4.2 “First time Configuration”)
Set the M1115NL address settings as per Section 0 ”Network Configuration”
Save the configuration and the M1115NL module is now ready to use.

Chapter 2 - Installation
2.1 General
All M1115NL Series modules are housed in a plastic enclosure with DIN rail mounting, providing options for up to 12
I/O points, and separate power & communications connectors. The enclosure measures 170 x 150 x 33 mm including
connectors. The antenna protrudes from the top
2.2 Power/Supply
Figure 2 – Power Connections
Figure 3 – Supply Connections
2.2.1 Requirements
The M1115NL power supply is a switch-mode supply and will accept a 15 - 30 volt DC power source connected to the
“Sup + & Sup -” terminals.
Both Supply and Battery connections have reverse polarity and over voltage protection.
If powered from the “Sup + & Sup -” terminals the Power Supply must be able to supply enough current to power all
operations, e.g. Module Quiescent current, Peak Transmit current, Digital and Analog I/O including loop supply, Battery charging (if applicable), etc.
The recommended “Supply” power source is +24VDC 2Amp (+12VDC 4Amp).
The module can be operated primarily from the supply terminals or in conjunction with a battery connected to the “BAT
+ & GND” terminals.

If a backup battery is used then the module Supply can have a lower current rating as the Peak current will be supplied by the battery.
To calculate the Power Supply current limit, use the following criteria.
Quiescent Current of the module is 200mA.
Module I/O total is 500mA
Peak Transmit current is 500mA
External Expansion I/O connected is 1000mA Max
Battery charging is 1000mA (Internally limited)
The following table represents the Supply current limit for different requirements
No Battery fitted
Battery fitted
Expansion I/O
No Expansion I/O
2700 mA
1700 mA
2200mA
1200 mA
E.g. If there is a battery connected and no expansion I/O the minimum current needed is 1.7Amps @13.8V this is
because the battery will provide peak current during radio transmissions.
If a backup battery is not connected and I/O modules are required and then the minimum current needed will be
approximately 2.2Amps @13.8V.
This is allowing for 500mA Peak Transmit current and up to 1 amp for expansion I/O
The power supply should be CSA Certified Class 2 approved for normal operation and if being used in Class I Div 2
explosive areas, the power supply must have a Class I Div 2 approval.
The power supply automatically charges a 13.8V Sealed Lead-Acid battery connected to the “BAT+” and “GND”
terminals at up to 1A.
The power supply input and battery charging are hosted on a 4-way terminal on the bottom edge of the module
abelled “Supply”.

2.2.2 Expansion I/O Supply
To allow increased I/O Capacity, a second 4-way terminal labelled “Expansion I/O” provides a +12 Volt supply (up to
1A) and RS485 communications for any 115S serial expansion I/O modules.
M1115NL
Figure 4 – Expansion I/O power & RS485
As a guide when using the I/O power connection from the M1115NL, the number of I/O modules is limited to three
115S-11 (using inputs), one 115S-12, or one 115S-13.
If more I/O Modules are required, you will need to calculate the overall current consumption using the following criteria
and power the modules from an external supply.
115S Module Static Current drain = 120mA
115S Digital Inputs require 13mA per active input
115S Digital Outputs require 25mA per active output
115S Analog Inputs and Outputs require 50mA per I/O when operating at 20mA
E.g. a single 115S-11 using inputs only has a current consumption of approximately 320mA so you could connect up
to three 115S-11 modules to the Expansion port without overloading the on board I/O power supply.
A single 115S-12 using all analog inputs and digital outputs has a current consumption of approximately 720mA so
you could only connect one.
Keep in mind that when calculating the current consumption for the expansion I/O, the maximum available current
from the onboard power supply is 1 Amp. If the overall Expansion I/O current consumption is over the 1 Amp
maximum an external power source will be required. The M1115NL provides up to 1 Amp for battery charging.

The internal Supply voltages can be monitored by reading the Modbus locations below.
The registers can also be mapped to a register or an analog output on another module within the radio network.

Floating Point Registers 38005 – 38008 also indicate the Supply voltage, Battery Voltage, +24V Supply and 115S
Supply voltages but in a voltage scale.
There are no dedicated discrete low voltage alarm indicators however each supply voltage does have a High and a
low Setpoint Status which can be used for this type of alarm.
See section 0“Analog Inputs” for details on how to configure these alarms.
2.2.4 Grounding
To provide maximum surge and lightning protection each module should be effectively earthed / grounded via a
“GND” terminal on the module – this is to ensure that the surge protection circuits inside the module are effective. The
module should be connected to the same common ground or earth point as the enclosure “earth” and the antenna
mast “earth”.
The M1115NL has a dedicated Earth connection screw on the bottom end plate next to the Supply terminals. All
EARTH wiring should be minimum 2mm² - 14 AWG
If using the M1115NL with serial Expansion I/O modules then all expansion modules must have a separate earth connection from the front terminal back to the common earth or ground point. See Figure 5 below

2.3 Radio
The following radio variants are available in the M1115NL dependent on the country of operation.
2.3.1 900 MHz Spread Spectrum radio
The radio operates in the 902-928 MHz ISM band and uses frequency hopping spread spectrum modulation, which
is a method of transmitting radio signals by rapidly switching the carrier among many frequency channels, using a
pseudo random sequence known to both transmitter and receiver as Hop Sets.
There are two Hop sets and each one uses a different pseudo random sequence of radio channels. Each Hop Set is
made up of 50 channels, which cycle through to the next channel after each transmission. (Some countries use fewer
channels, e.g. New Zealand).
The receiver is continually scanning all channels in the hop-set and when a valid data packet is heard, it locks on to
the channel and receives the data.
A spread-spectrum transmission offers some advantages over a fixed-frequency transmission. These are - Spreadspectrum signals are more resistant to narrowband interference, they are difficult to intercept or eavesdrop because
of the pseudorandom transmission sequences and transmissions can share a frequency band with other types of
conventional transmissions with minimal interference.
2.3.2 Meshing capability
The DAWN Wireless WIBMesh protocol is based on the “Ad hoc On Demand Distance Vector” (AODV) routing algorithm which is a routing protocol designed for ad hoc networks.
AODV is capable of unicast and multicast routing and is an on demand algorithm, meaning that it builds and maintains
these routes only as long as they are needed by the source devices.
The Protocol creates a table, which shows the connection routes to other device in the system. The Protocol uses
sequence numbers to ensure the routes are kept as current as possible. It is loop-free, self-starting, and can scale to
a large numbers of nodes.
See section 3.4 “WIBMesh” for more details on configuration.
2.4 Antenna
The M1115NL module will operate reliably over large distances. The distance that can be reliably achieved will vary
with each application and depend on the type and location of antennas, the degree of radio interference, and obstructions (such as hills or trees) to the radio path.
Typical reliable distances are detailed below, however longer distances can be achieved if antennas are mounted in
elevated locations – such as on a hill or on a radio mast.
Using the 900 MHz Spread Spectrum radio the distances achievable will be:
• USA/Canada15 miles - 6dB net gain antenna configuration permitted (4W EIRP)
• Australia/NZ 12 km - Unity gain antenna configuration (1W EIRP)

To achieve the maximum transmission distance, the antennas should be raised above intermediate obstructions so
the radio path is true “line of sight”. Because of the curvature of the earth, the antennas will need to be elevated at
least 15 feet (5 metres) above ground for paths greater than 3 miles (5 km). The modules will operate reliably with
some obstruction of the radio path, although the reliable distance will be reduced. Obstructions that are close to either
antenna will have more of a blocking effect than obstructions in the middle of the radio path. For example, a group of
trees around the antenna is a larger obstruction than a group of trees further away from the antenna.
The M1115NL module provides a range of test features, including displaying the radio signal strength. Line-of-sight
paths are only necessary to obtain the maximum range. Obstructions will reduce the range however, but may not prevent a reliable path. A larger amount of obstruction can be tolerated for shorter distances. For very short distances, it
is possible to mount the antennas inside buildings. All radio paths require testing to determine if they are reliable - refer section 5.4 “Network Statistics” Where it is not possible to achieve reliable communications between two modules,
then a third module may be used to receive the message and re-transmit it. This module is referred to as a repeater.
This module may also have input/output (I/O) signals connected to it and form part of the I/O network - refer to Chapter 4 Configuration of this manual.
An antenna should be connected to the module via 50 ohm coaxial cable (e.g. RG58, RG213, Cellfoil, etc) terminated
with a male SMA coaxial connector. The higher the antenna is mounted, the greater the transmission range will be,
however as the length of coaxial cable increases so do cable losses. For use on unlicensed frequency channels, there
are several types of antennas suitable for use. It is important antennas are chosen carefully to avoid contravening the
maximum power limit on the unlicensed channel - if in doubt refer to an authorised service provider.
The net gain of an antenna/cable configuration is the gain of the antenna (in dBi) less the loss in the coaxial cable (in
dB).
The net gain of the antenna/cable configuration is determined by adding the antenna gain and the cable loss. For
example, a 6 element Yagi with 70 feet (20 metres) of Cellfoil has a net gain of 4dB (10dB – 6dB).

Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture.
Moisture ingress in the coaxial cable is a common cause for problems with radio systems, as it greatly increases the
radio losses.
We recommend that the connection be taped, firstly with a layer of PVC Tape, then with a vulcanising tape such as
“3M 23 tape”, and finally with another layer of PVC UV Stabilised insulating tape. The first layer of tape allows the
joint to be easily inspected when trouble shooting as the vulcanising seal can be easily removed.
Where antennas are mounted on elevated masts, the masts should be effectively earthed to avoid lightning surges.
For high lightning risk areas, surge suppression devices between the module and the antenna are recommended.
If the antenna is not already shielded from lightning strike by an adjacent earthed structure, a lightning rod may be
installed above the antenna to provide shielding.
Dipole and Collinear antennas.
A collinear antenna transmits the same amount of radio power in all directions - and they are easy to install and use
because they do not need to be aligned to the destination. The dipole antenna with integral 15 ‘cable does not require
any additional coaxial cable; however a cable must be used with the collinear antennas.
Collinear and dipole antennas should be mounted vertically, preferably 1 wavelength away from a wall or mast to
obtain maximum range.

Yagi antennas.
A Yagi antenna provides high gain in the forward direction, but lower gain in other directions. This may be used to
compensate for coaxial cable loss for installations with marginal radio path.
The Yagi gain also acts on the receiver, so adding Yagi antennas at both ends of a link provides a double
improvement.
Yagi antennas are directional. That is, they have positive gain to the front of the antenna, but negative gain in other
directions.
Hence, Yagi antennas should be installed with the central beam horizontal and must be pointed exactly in the direction
of transmission to benefit from the gain of the antenna. The Yagi antennas may be installed with the elements in a
vertical plane (vertically polarised) or in a horizontal plane (horizontally polarised), however both antenna must be
in the same plane for maximum signal. If the antenna are mounted in different planes the receive signal level will be
reduced by around 30dB.
Figure 8 - Yagi Antenna Mounting
For a two-station installation, with both modules using Yagi antennas, horizontal polarisation is recommended. If there
are more than two stations transmitting to a common station, then the Yagi antennas should have vertical polarisation,
and the common (or “central” station should have a collinear (non-directional) antenna.
Note that Yagi antennas normally have a drain hole on the folded element - the drain hole should be located
on the bottom of the installed antenna.

The M1115NL front panel provides connections for the following
• Eight Digital Input /Output (DIO1-8).
• Two 12 bit, 0.1% accuracy differential analog inputs.
• Two single ended 12 bit, 0.1% accuracy analog inputs.
• Two 15 bit, 0.1% accuracy current sourcing analog outputs.
• Connection terminals for Common and +24V Analog Loop Supply (ALS maximum current limit is 150mA).
2.5.3 Digital Inputs
Each digital I/O channel on the M1115NL can act as either an input or an output. The input/output direction is
automatically determined by the connections and configuration of the I/O.
If you have an I/O channel wired as an input but operate the channel as an output. No electrical damage will occur
however, the I/O system will not operate correctly.
If operating the channel as an output and performing a “read inputs” on this location it will indicate the status of the
output.
Marked DIO1-8 the Digital inputs share the same terminals as the Digital outputs on the M1115NL module.
A digital input is activated by connecting the input terminal to EARTH or Common, either by voltage-free contact, TTL
Level, or transistor switch.
Each digital input has an orange indication LED that will turn on when the input has been connected to a GND or
common.

2.5.4 Pulsed Inputs
The M1115NL supports 8 x digital signals, of which inputs 1-4 can be used as pulsed inputs.
The maximum pulse frequency is 50 KHz for Input 1 & 2 and 1 KHz for Input 3 & 4.
Digital/Pulsed inputs are suitable for TTL signal Level, NPN-transistor switch devices or voltage-free contacts (relay/
switch with debounce capacitor).
Figure 14 – Pulsed Input Wiring
Frequencies greater than 1 KHz need to use a TTL logic drive or an external pull-up resistor. Pulsed inputs are
converted to two different values internally. First is the Pulse Count, which is an indication of how many times the input
has changed state over a configured time period. Secondly there is a Pulse Rate which is an analog input derived
from the pulse frequency. E.g. 0 Hz = 4mA and 1 KHz = 20mA.

2.5.5 Digital Outputs (Pulsed Outputs)
Digital outputs are open-collector transistors and are able to switch loads up to 30VDC, 200mA.
The 8 digital outputs share the same terminals as the digital input. These terminals are marked DIO1-8.
Figure 15 – Digital Output Wiring
When active, the digital outputs provide a transistor switch to EARTH (Common).
To connect a digital output, refer to “Figure 15” above. A bypass diode (IN4004) is recommended to protect against
switching surges for inductive loads such as relay coils.
The digital channels DIO1-4 on the M1115NL module can be used as pulse outputs with a maximum output frequency
of 1 KHz.
Digital Output Fail Safe Status
As well as indicating the Digital Output status (on / off), the LEDs can also indicate a communications failure
by flashing the Output LED. This feature can be utilised by configuring a Fail Safe time and status on the “I/O
Configuration” web page as shown below.

Figure 16 – Digital Output Failsafe Times
The Fail Safe Time is the time the output counts down before activating a Fail Safe state.
Normally this would be configured for a little more than twice the update time of the mapping that is sending data to it.
This is because the Fail Safe Timer is restarted whenever it receives an update. If we send successive update
messages and fail to receive both the timer counts down to zero and then activates the Failsafe state.
If the Failsafe state is enabled (ON) this will indicate with the LED flashing briefly OFF and the digital output will turn
on.
If the Failsafe state is disabled (OFF) this will indicate with the LED flashing briefly ON and the digital output will turn
off.

2.5.6 Analog Inputs
The M1115NL can provide two floating differential analog inputs and two grounded single-ended analog inputs.
Analog Input 1 & 2 can automatically measure Current (0-20 mA) or Voltage (0-25V) depending on what is connected
to the input.
Analog input 3 & 4 must be configured to measure Current (0-20mA) or Voltage (0-5V) via the DIP switches under the
Side Access Configuration Panel (See Section 2.5.2 ).
An internal 24V Analog Loop Supply (ALS) provides power for any current loops with a maximum current limit of
150mA.
The LEDs have an analog diagnostic function and will indicate the status of the input.
If the current is less than 3.5 mA the LED will be off and if greater than 20.5mA the LED will be on.
The LED will flicker with the duty cycle relative to the analog reading in this range. (Note by default there is a 5 second
delay on the input because of the Filter)
Also, LEDs beside AI1+, AI2+ flash according to current on these inputs. LEDs beside AI1- and AI2- flash according to
the voltage on the Analog inputs.
Differential Current Inputs (AIN 1 & 2 only)
Differential mode current inputs should be used when measuring a current loop, which cannot be connected to earth
or ground. This allows the input to be connected anywhere in the current loop. Common mode voltage can be up to
27VDC.
The diagram below indicates how to connect Loop powered or externally powered devices to the M1115NL Differential
Analog Inputs.

Single Ended Current Inputs (AIN 3 & 4 only)
Single-ended current input mode is useful if the sensor loop is grounded to the M1115NL module. Devices can be
powered from the 24V Analog Loop Supply (ALS) generated internally from the module.
The Dip Switches are used to determine if the inputs will be current or voltage.
Dip Switches 1 & 2 are used for or Analog 3 and Dip Switches 3 & 4 are used for Analog 4
For Current set both Dip Switches to the “On” position, for Voltage set both to “Off”

2.5.7 Analog Outputs
The M1115NL module provides two 0 - 24 mA DC analog outputs for connecting to instrument indicators for the
display of remote analog measurements.
The M1115NL Analog outputs are a sourcing output and should be connected from the analog output terminal through
the device or indicator to Common. See diagram for connections.
The LEDs function as a primitive level indicator depending on current - Dim for 4mA and Bright for 20mA

Chapter 3 - Operation
3.1 Overview
The M1115NL range of I/O modules has been designed to provide standard “off-the-shelf” telemetry functions, at an
economic price. Telemetry is the transmission of data or signals over a long distance via radio or twisted-pair wire
cable
3.2 Indications
When power is initially connected to the module it will perform some internal setup and diagnostics checks to
determine if the module is operating correctly. These checks will take approximately 40 seconds. The table below
shows the correct LED sequences.

LED’s display the status of each of the eight DIO’s when used as inputs. (If the LED is lit then the input is on).
Digital Outputs
When the DIO’s are used as outputs the LEDs will display the status of each of the digital output (If the LED is lit then
the output is on). The LED’s also indicate if the output has not been updated by flashing. Mostly ON will indicate the
Failsafe state is ON and mostly OFF will indicate the Failsafe state is OFF.
Analog Inputs
Two LEDs exist for each Differential analog input. The first LED (+) is used to indicate the analogue input is reading a
Current (mA), the second LED (-) indicates the input is reading Voltage.
Each of the analog input LEDs will flash with increasing speed and intenseness depending on the level of the input
(4mA = slow/dim and 20mA= fast/bright)
For each of the single ended analog channels, the LED indicates when the input is reading Current or Voltage by
flashing the LED with the level of the input (4mA = slow/dim and 20mA= fast/bright).
Analog Outputs
Each Analog output has an LED in series which will indicate the output current by increasing/decreasing the intensity
of the LED. (4mA = dim and 20mA= bright)

3.3 System Design
3.3.1 Radio Channel Capacity
Messages sent on a cable link are much faster than on a radio channel, and the capacity of the radio channel must be
considered when designing a system. This becomes more important as the I/O size of a system increases.
The modules are designed to provide “real-time” operation or Change of State (COS). When an input signal changes,
the change message is sent to the output. The system does not require continuous messages as in a polling system.
Update messages are intended to check the integrity of the system, not to provide fast operation. Update times should
be selected based on this principle. The default update time in the mappings is 10 minutes - we recommend that you
leave these times as is unless particular inputs are very important and deserve a smaller update time.
It is important that radio paths be reliable. For large systems, we recommend a maximum radio channel density of
300 messages per minute, including change messages and update messages. We suggest that you do not design
the system with more than 300 messages per minute as this does not take into account any network communication
overheads. Note that this rate assumes that all radio paths are reliable and the network topology (mesh) is stable poor radio paths will require retransmissions and will reduce the channel density. If there are other users on the radio
channel, then this peak figure will also decrease.
Having remotes radios dropping in and out of communications can also increase overall network traffic because the
network would need to relearn the communication paths each time the module comes back on line.
Dual Band Operation
The M1115NL radio band is split into two sub-bands, 902-914 MHz (Low) and 915–928 MHz (High). In America and
Canada, the M1115NL uses both sub-bands - but in other countries, e.g. Australia only the high band is available. In
America and Canada, it is possible to restrict the frequency hopping of the 905U to only the high or low band. If there
are many 905U systems in the same area, this technique will help to separate systems to avoid radio interference.
Note that this technique is only possible in countries that utilize the full 902-928MHz bandwidth, i.e. America / Canada,
etc.
The radio sub-band can be changed by selecting the “Hop Set” on the Radio page.
3.3.2 Radio Path Reliability
Radio paths over short distances can operate reliably with a large amount of obstruction in the path. As the path
distance increases, the amount of obstruction that can be tolerated decreases. At the maximum reliable distance,
“line-of-sight” is required for reliable operation. The curvature of the earth becomes more of an obstacle if the path is
greater than several kilometres (or miles), and therefore needs to be allowed for. For example, the earth curvature
over 5 miles (8km) is approx 10 feet (3m), requiring antennas to be elevated at least 13 feet (4m) to achieve “line-ofsight” even if the path is flat.
A radio path may act reliably in good weather, but poorly in bad weather - this is called a “marginal” radio path. If the
radio path is more than 20% of the maximum reliable distance (see Specification section for these distances), we
recommend that you test the radio path before installation. Each M1115NL module has a radio path-testing feature refer to Section 5.2 ”Connectivity” of this manual.

IM 22B01D01-01E-A
July 2009
38
There are several ways of improving a marginal path:• Relocate the antenna to a better position. If there is an obvious obstruction causing the problem, then locating the antenna to the side or higher will improve the path. If the radio path has a large distance, then increasing the height of the antenna will improve the path.
• Use an antenna with a higher gain. Before you do this, make sure that the radiated power from the new antenna
is still within the regulations of your country. If you have a long length of coaxial cable, you can use a higher gain
antenna to cancel the losses in the coaxial cable.
If it is not practical to improve a marginal path, then the last method is to use another module as a repeater. A
.repeater does not have to be between the two modules (although often it is). If possible, use an existing module in the system, which has good radio path to both modules. The repeater module can be to the side of the two
.modules, or even behind one of the modules, if the repeater module is installed at a high location (for example, a tower, or mast). Repeater modules can have their own I/O and act as a “normal” M1115NL module in the system.
3.3.3 Design for Failures
All well designed systems consider system failure. I/O systems operating on a wire link will fail eventually, and a radio
system is the same. Failures could be short-term (interference on the radio channel or power supply failure) or longterm (equipment failure).
The modules provide the following features for system failure:•
•
•
Outputs can reset if they do not receive a message within a configured time. If an output should receive an update or change message every 10 minutes, and it has not received a message within this time, then some form of
failure is likely. If the output is controlling some machinery, then it is good design to switch off this equipment until communications has been re-established.
The modules provide a “drop outputs on comms fail” time. This is a configurable time value for each output. If a message has not been received for this output within this time, then the output will reset (off, in-active, “0”). We suggest that this reset time be a little more than twice the update time of the input. It is possible to miss one update message because of short-term radio interference, however if two successive update messages are missed, then long term failure is likely and the output should be reset. For example, if the input update time is 3 minutes, set the output reset time to 7 minutes.
A module can provide an output, which activates on communication failure to another module. This can be used to provide an external alarm that there is a system fault.
3.3.4 Indicating a Communications Problem
There are two ways to indication communications problems.
Fall-to-transmit alarm
The first method is to setup a communications indication on a register of your choice when configuring a mapping.
This can be done using an existing mapping (do not need to setup a special comms mapping).
When entering a Block Write or Gather/Scatter Mapping you need to enter into the “FailReg” field a register location
that you wish to indicate a communications fail (As mentioned previously this register can be a local DIO (Reg 1-8) or
an internal register.
When ever the module tries to send this mapping and fails to get a response (Ack) it will turn on the output.
The Comms Fail indication will clear on the next successful transmission of the mapping.
This method will work with any number repeaters in the link; however it will only indicate a failure to transmit if the
mapping has the “ACK” field checked.

IM 22B01D01-01E-A
July 2009
39
It will not give a Fail indication if the mappings are configured as Transmit only (do not have the “Ack” ticked).
Fail-to-receive alarm
The second method is to set up a “Comms Link” indication on the receiving end using normal Write Mappings on the
transmitting end and the “Fail Safe Time” function on the receiving end. Setup a comms mapping from an unused digital
input (can be an internal signal, i.e. Supply fail) and have it mapped to the output that will indicate the communication
status. The input will be updated at a given time interval (default will be 5 seconds) but select a time that will give a good
indication of failure but not update so much that it generates too many comms check messages, e.g. 30 seconds.
On the receiving end, configure a “Fail Safe Time” on the output that it being mapped to of twice the update time e.g.
1 minute. Next, configure the Fail Safe State to be on “ticked” which will turn on the output when it fails to be updated.
Alternatively, you could invert the mapping so the output was always on and then trigger the “Fail Safe State” to go off
when not updated.
This method will work with any number repeaters in the link.
You should use separate outputs to indicate “comms OK” of different remote modules
3.3.5 Testing and Commissioning
We recommend that that the system is fully tested on the bench before installation. It is much easier to find configuration
problems on the bench when the modules are next to each other as apposed to being miles apart.
When the system is configured and you are happy that it all works, backup the configurations of all the modules.
After installation, record the radio signal strength and background noise level for each radio link. If there are future
communications problems, you can compare the present measurements to the as-commissioned values. This is an
effective way of finding problems with antennas, cables, and changes in the radio path (for example, the erection of new
buildings).
3.4 WIBMesh
The DAWN WIreless WIBMesh protocol is based on the “Ad hoc On-demand Distance Vector” (AODV) routing algorithm
which is a routing protocol designed for ad hoc networks.
AODV is capable of unicast (single addressed message) routing and is an “on-demand” protocol, meaning that it builds
and maintains these routes only as long as they are needed by the source devices. In other words the network is silent
until a connection is needed. The Protocol creates a table, which shows the connection routes to other device in the
system and uses sequence numbers to ensure the routes are kept as current as possible.
When a module in a network needs to make a connection to another module it broadcasts a request for connection. Other
modules forward this message, and record the module address that they heard it from, creating a table of temporary
routes back to the starting module. If a module receives a request and it already has an existing route to the request
destination, it will send a message backwards through the temporary route to the requesting module.
Each request for a route has a sequence number. Modules use this sequence number so that they do not repeat route
requests that they have already passed on. Another such feature is that the route requests have a “time to live” number
that limits how many times they can be retransmitted. Another such feature is that if a route request fails, another route
request may not be sent until twice as much time has passed as the timeout of the previous route request.
The original starting module then begins using the route that has the least number of hops. Unused entries in the routing
tables are recycled after a time.
When a link fails, a routing error is passed back to a transmitting node, and the process repeats.

Chapter 4 - Configuration
4.1 Module Configuration
Module configuration can be done using the DAWN Wireless MConfig utility or via inbuilt web pages. We recommend
the software be used as the primary config as is easier to use and simplifies the overall configuration. It is also project
based which means you can group a number of modules in one configuration file.
For instructions on web page based configurations see Appendix E: “Web Page Configuration”
The Utility is available from the download section on the DAWN Wireless Technologies web site - www.DAWN
WIrelesstech.com.
After downloading, run the file to install the software on to your computer.
The software is compatible with all current Windows versions and uses a simple point and click interface.
Configuration of the module can be via USB or Ethernet connection.

4.2 First time Configuration
The M1115NL has a built-in web server, containing web pages for analyzing and minor modification to the module’s
configuration. The configuration can be accessed using any web browser however we recommend using Microsoft®
Internet Explorer 8.
4.2.1 Default IP Address
The default factory IP Address of the M1115NL is 192.168.0.1XX, where XX is the last two digits of the serial number
(the default “Setup IP address” is shown on the printed label on the side of the module)
Netmask 255.255.255.0
Username is “user” and the default password is “user”
The M1115NL will temporarily load some factory-default settings if powered up with the #6
dipswitch under the side configuration panel switched on. When in SETUP mode, wireless
operation is
disabled. The previous configuration remains stored in non-volatile memory and will only change
if a configuration parameter is modified and the change saved.
Do not forget to set the switch back to the OFF position and re-cycle the power at the conclusion of the
configuration for normal operation otherwise, it will continue to boot into the default IP address.
4.2.2 Accessing Configuration
The Default IP address is in the range 192.168.0.XXX and so will require a PC on this network or be able to change
the network settings to access the module configuration.
This is the procedure for changing A PC network settings.
You will need a “straight-through” Ethernet cable between the PC Ethernet port and the M1115NL. The factory default
Ethernet address for the M1115NL is 192.168.0.1XX where XX are the last two digits of the serial number (check the
label on the back of the module).
Connect the Ethernet cable between unit and the PC configuring the module.
Open the side configuration panel and set the #6 Dipswitch to ON.
With this switch on the M1115NL will always start with the Ethernet IP address 192.168.0.1XX, subnet mask
255.255.255.0, Gateway IP 192.168.0.1 and the radio IP address 192.168.2.1. Do not forget to set the switch back to
the OFF position and restart the module at the conclusion of configuration.

4.2.3 Power up the M1115NL module
Open “Network Settings” on your PC under Control Panel. The following description is for Windows XP - earlier
Windows operating systems have similar settings.
Open “Properties” of Local Area Connection.
Select Internet Protocol (TCP/IP) and click on Properties.
On the General tab, enter IP address 192.168.0.1, Subnet mask 255.255.255.0 and press “OK”
Figure 25 – Network Settings
The simplest way to check ethernet communications is to use the “Ping” command
From the Windows Start menu, select “Run” then type “command”
A Command Prompt DOS window will open and from there you can use the Ping command to check if you are able to
connect to the module.
Type ping 192.168.0.1XX (where XX is the last two digits of the serial number)
You should then see a reply like below.

You can then open Internet Explorer and ensure you can connect to the IP address selected. If the PC uses a proxy
server, ensure that Internet Explorer will bypass the Proxy Server for local addresses.
This option may be modified by opening Tools -> Internet Options -> Connections Tab -> LAN Settings->Proxy Server
-> bypass proxy for local addresses.
Enter the default IP address for the M1115NL https://192.168.0.1XX where XX is the last two digits of the serial
number.
Enter the username “user” and default password “user”.
When Configuration is complete switch the M1115NL Factory Default dip-switch to RUN and cycle power to resume
normal configured operation.
You should now see the Module Welcome Screen (below)

4.2.4 Over the Air Web Based Configuration
The M1115NL modules communicate using Standard Ethernet Protocols which makes it possible to connect to other
M1115NL module within the radio network for over the air diagnostics or configuration changes.
A little forethought when designing the system is required as some minor configuration settings are needed to
implement the over air configuration.
The Multi point to point system shown below in Figure 28 will require the following.
• Default Gateway address in all remote modules needs to point back to the Central M1115NL module radio IP
address (i.e. 10.0.0.1)
• Central M1115NL needs to have the “IP Gateway Mode” enabled on the “Mesh” webpage (see Appendix F: “Web Page Configuration“ for details).
• Ethernet IP address range on the remote modules must be different to the Ethernet IP address range on the
Central M1115NL module or disabled (see Appendix F: “Web Page Configuration“)
• PC must have its Default Gateway address set to the Central M1115NL Ethernet IP Address or it must have a
route added to its default routing table, e.g. “ROUTE ADD 10.0.0.0 MASK 255.255.255.0 192.168.1.1
If the system is configured as per above it will allow configuration and diagnostics access for all remote modules from
the PC connected to the Central M1115NL module.

Instructions for upgrading Firmware are as follows
1. .You will need valid DAWN Wireless M1115NL Firmware upgrade files. Contact DAWN Wireless Technologies for the
latest version. . Files must not be renamed, compressed, or zipped.
2. .You will also need a dedicated USB Flash drive which needs to be formatted and completely free of any other file.
Copy the firmware files to the Flash drive making sure they are in the root of the drive and not in a sub directory.
3. .Before upgrading the firmware it is good practice to backup the existing configuration. Go to the “System Tools”
webpage and save the configuration by selecting “Read Configuration File” and when the XML file is displayed
press <CTRL> F5 to refresh the cache and select “Save As” or “Save Page As” on the File menu to save the XML
as a file.
4. .To upgrade, remove the “Configuration Panel” from the side of the module and plug the Flash drive into the USB
port. If the module is mounted on a DIN rail with other I/O modules it will need to be removed to gain access to the
side panel.
5. .Power cycle the module to begin the upgrade process. As the module powers up it will recognise that a Flash drive
has been installed and start upgrading the firmware. You will see the normal boot up LED sequence (see 3.2 “Indi
cations” for details) however the orange indication will be on for longer.
DO NOT remove the Flash drive or interrupt the power to the module while this is happening. If the upgrade process
is interrupted module could become unserviceable and will need to be returned to DAWN Wireless for repair.
Upgrade will take approximately 2 minutes and 40 seconds, 120 seconds over the normal boot time. When update is
complete (Solid Green PWR LED indication) remove the flash drive.
Figure 31 - Firmware Upgrade LED Indications
6. .The upgrade process will clear the module flash so you will need to load the configuration file back into the module.
To do this select “Write Configuration File” from the “System Tools” menu. Browse for the saved XML file and when
loaded press Send and then Reset.

4.7 Serial Expansion I/O
4.7.1 Adding modules
Additional 115S serial expansion I/O modules can be added if more I/O is required.
When connecting expansion I/O module to the M1115NL the RS485 serial port is configured to communicate DAWN
Wireless protocol by default.
The default serial parameters of the RS485 port are 19200, N, 8, 1 which match the defaults of the 115S serial
expansion modules. The parameters can be changed, to increase poll speeds in larger systems however the serial
modules will need to match that of the M1115NL RS485 port.
Also if more than 3 serial expansion modules are added the “Maximum Connections” for the RS485 port on the
“Serial” page will need to be adjusted.
Note: Reducing the “Maximum connections” will slightly improve the serial scan time however make sure the
slave addresses falls within the “Maximum connections”. If the Slave address is above the “Maximum
connections”, it will not be polled.

Next, connect the serial expansion module and take note of the module address (Rotary switches on the bottom) as
this address will be used as an offset to locate the I/O within the M1115NL.
Also make sure the last module in the RS485 loop has the termination switch on (down).
Failure to terminate the RS485 correctly will result in the modules not operating correctly.
4.7.2 115S Expansion I/O Memory Map
I/O data on the 115S module is read into memory locations according to their Modbus address. The maximum number
of Modbus addresses is 24.
Each 115S module has an “Offset” which applies to the location of all of its registers. This Offset is equal to the units
Modbus address multiplied by 20.
If the modules Modbus address is 15, the Offset value will be 15 X 20 = 300.
E.g. If connecting a 115S-11 (16 x DIO) with address #15
• Digital input 1 will be at register location 10301.
• Digital Output 1 will be at register location 301
If using a 115S-12 (8 x DIO & 8 AIN) with address 16
• Digital input 1 will be at register location 10321
• Analog input 1 will be at register location 30321
See Appendix C: “Expansion I/O Store Registers”. For a more detailed address map of the serial expansion I/O
modules.

Chapter 5 - Diagnostics
5.1 IO Diagnostics
Figure 33 - I/O Diagnostics
Selecting this option from the main screen will allow some basic reading and writing of the I/O store registers within
the module.
To read a register location, enter an address location, e.g. 10001 (for digital Inputs), enter a count (number of
consecutive registers) and then press the “Read” button
Below the buttons, you will see the returned address location and the returned values
To “Write” to outputs, enter the address location, count, and value and then press the “Write” button.
You will then see the outputs change to the value you entered.
E.g. Write to Register 1 with a count of 8 and a value of 1 will turn all the Local Digital Outputs on.
Write to Register 40001 with a count of 2 and a value of 49152 will turn all the Local Digital Outputs on.
Note: If when reading a register and getting the symbol “–“this indicates that the register has not been written to and
so it has no value (not even zero).
Note: if there is a mapping configured and any one of the source register values has a “–“ the mapping will not be sent
(see section 0“Invalid” register state” for more details.
A mapping will only be sent when all registers have a value.
Using the I/O Diagnostics you can check the register locations for these “-“ values and even write values if required.
If when reading the Status of the DIO on the module you see the value “3”, this indicates that the DIO is being used as
an output in the “ON” state.

5.1.1 Modbus Error Registers
Each of the Expansion I/O modules have diagnostics registers that can indicate any
Modbus Errors, Codes, Counts, etc.
30017 + Offset = Modbus Error Counter (number of errors the modules has had)
30018 + Offset = Modbus Last Error Code (see Appendix D for codes)
30019 + Offset = Modbus Lost Link Counter (number of Communication Errors)
30020 + Offset = Modbus Module Type
• dec 257 (101hex) indicates a 115S-11
• dec 513 (201hex) indicates a 115S-12
dec 769 (301hex) indicates a 115S-13
5.2 Connectivity
The Connectivity webpage displays connections and available networks. The “Connected Devices” section displays
the radio channel, received signal strength, and radio data rate for each Client or Access Point by their MAC Address.
The readings shown are based upon the last received data message from the Access Point or Client. Client stations
also display a list of detected Access points (Site Survey), including network name (SSID), channel and maximum
data rate.

Qual

Index)
which indicates no direct link to that station.
The LQI is a logarithmic representation of the number of bit errors
in the frame that were corrected by the Forward Error Correction
algorithm. Each data bit is encoded with 7 forward error correction
bits, so a 100 byte frame contains 100 * 8 bits / byte * 7 FEC bits/bit
= 5600 bits. (see below this table for details)

LQI (Link Quality Indication)
• Because a typical frame is around 80 bytes (4480bits), you should not normally see any readings between 75 and 99.
• Communication becomes unreliable with LQI around 30.
• As the LQI drops below 25, nearly every frame will have enough bit errors that the FEC will no longer be able to
recover the original data, so the frame will be corrupted. Hence you will hardly ever see a reading below 25.
• With signal strength (RSSI) -100 dBm or better, the LQI should always read 100. You should expect LQI readings
below 100 with signal strength -105 dBm or worse.
If you have good signal strength and are getting LQI readings less than 100, this is a sign of interference, or of a
problem with the radio of the unit you are using.

Network Diagnostics allows you to check the communications path to other modules within the system.
There are two options for checking the communications.
Ping
Ping is a standard Network instruction that sends out a small data probe to the IP address configured letting you know
if you have a communication path or not.
You will receive a response for each Ping, which will show a packet size, IP Address, Sequence number and a time in
milliseconds.
Followed by a summary showing the number of packets transmitted, the number of packets received, any lost packets
and the Minimum, Average and Maximum Ping times in milliseconds.
A Ping can be done on either the Radio Network or Ethernet Network. The ping command will automatically select the
correct network interface according to the address selected.
Remote IP Address – This is the IP address that you want to Ping
Count / Max Hops – This is the number of Ping probes that are send out. You should see this many responses come
back.
Trace Route
Because the modules use the AODV protocol which is a routing protocol capable of finding its own path through the
network it can be difficult to determine the selected communications path.
“Trace Route” allows you to trace the communications path through the network.
Example from the screen shot below:
1
192.168.2.108
(192.168.2.108)
874 ms
“1” = Hop number
“192.168.2.108” = DNS Name of the device.
“(192.168.2.108)” = IP Address of the device.
“874 ms” = A roundtrip response time (ping) in milliseconds from the Local IP to each hop point.
Figure 36 - Trace Route
E.g. The above example shows the Ping time from the Host to the first IP address (192.168.0.102) is 874 msec, The
jump from Hop1 (192.168.0.108 to Hop2 (192.168.0.106) is 685msec, etc.

Appendix C: Expansion I/O Store Registers
To calculate the I/O Store register you need to find the address of the I/O point from the module tables below
and then add the offset.
The Offset is the Modbus address multiplied by 20.
E.g1. Digital input #1 on an 115S-11 with address 5 would be: (5x20) +10001 = 100+10001 = 10101
E.g2. Digital output #2 on an 115S-11 with address 6 would be: (6x20) +2 = 120+2= 122
E.g3. Analog input #3 on an 115S-12 with address 3 would be: (3x20) +30003 = 60+30003 = 30063.
E.g4. Analog Output #8 on an 115S-13 with address # 7 would be: (7x20) + 40007 = 140+40007 = 40147

Meaning
The function code received in the query is not an allowable
action for the server (or slave). This may be because the
function code is only applicable to newer devices, and was not
implemented in the unit selected. It could also indicate that the
server (or slave) is in the wrong state to process a request of
this type
The data address received in the query is not an allowable
address for the server (or slave). More specifically, the
combination of reference number and transfer length is invalid.
For a controller with 100 registers, the PDU addresses the first
register as 0, and the last one as 99. If a request is submitted
with a starting register address of 96 with a quantity of 4
registers, then this request will successfully operate on registers
96, 97, 98, 99. If a request is submitted with a starting register
address of 96 and a quantity of registers of 5, then this request
will fail with Exception Code 0x02 “Illegal Data Address”.
A value contained in the query data field is not an allowable
value for server (or slave). This indicates a fault in the structure
of the remainder of a complex request, such as that the implied
length is incorrect. It specifically does NOT mean that a data
item submitted for storage in a register has a value outside the
expectation of the application program, since the MODBUS
protocol is unaware of the significance of any particular value of
any particular register.
An unrecoverable error occurred while the server (or slave) was
attempting to perform the requested action.
Specialized use in conjunction with programming commands.
The server (or slave) has accepted the request and is
processing it, but a long duration of time will be required to do
so. This response is returned to prevent a timeout error from
occurring in the client (or master).
Specialized use in conjunction with programming commands.
The server (or slave) is engaged in processing a long–duration
program command. The client (or master) should retransmit the
message later when the server (or slave) is free.

Appendix E: Web Page Configuration
Network Configuration
You can view or modify Ethernet network parameters by selecting the “Network” menu. When prompted for username
and password, enter “user” as the username, and “user” as the password in the password field (This is the factory
default – See section 4.3 ”Module Information ” to change). If you have forgotten the IP address or password, the
Factory Default switch may be used to access the existing configuration. Refer to section above for this procedure.
The Network Configuration page allows configuration of parameters related to the wired and wireless Ethernet
interfaces. In general, IP address selection will be dependant upon the connected wired Ethernet device(s) – before
connecting to an existing LAN consult the network administrator.
Figure 43 - Network Configuration Screen
Note: If configuring a system of M1115NL radios and the Ethernet IP address of each of the M1115NL modules
is configured with the same Address and if using a common PC to do the configuring there can be some issues
with web pages not reading correctly.
This is because Web Browsers associate web pages with an Ethernet IP address, they also cache web pages to
speed up the loading process.
This means that if a browser connects to a previously loaded IP address it may sometimes load the web page from
the cache and not from the live device.
To overcome this all modules must be configured with an individual ethernet IP address or when connecting to the
module force the web pages to be reloaded from the Device instead of from cache by pressing <CRTL F5> after the
page has loaded.
Web Browsers can be configured to flush the cache after each session, review browser help for details on how this is
done.

This is the address that the device will use to forward messages to remote hosts
that are not connected to any of the local networks (Ethernet or Wireless). This is
only required if the wired LAN has a Gateway unit which connects to devices
beyond the LAN - for example, Internet access. If there is no Gateway on the
LAN, set to the same address as the Station used for remote configuration - that
is, the “Ethernet Interface IP Address” below.
Ethernet Interface
Enables or disables the Ethernet interface. If the Ethernet connection is not used
you can disable which will marginally improve the boot time and lower the current

This is the unique hardware address of the M1115NL and is assigned in the
Factory.
Checking this item enables DHCP client on the M1115NL. A DHCP client
requests its IP address from a DHCP server, which assigns the IP Address
automatically. To use this option, you will need to have a DHCP server configured
on your network. The module will attempt to register its configured unit name with
any connected DNS server.

Enabling this option will advertise all other communicating modules that an
Ethernet Network is connected (IP address range configured under Network
Settings) and that all traffic for this network can be routed through this IP address.
Care should be taken when enabling this option as it can increase overall network
traffic. Default is off – Should remain off unless there is an Ethernet network
connected and other devices on the radio network need to communicate to it.
The radio will use this threshold levels when establishing a mesh link with other
radios in the system. It represents a 0-100% level of link quality (100 being the
best). If the Link Quality is lower than the threshold the link will be ignored.
Link Quality can be monitored on the Connectivity web page. If the link quality is
lower than this threshold, then mesh routes will not be assigned over this link
The radio will use this threshold level when establishing a mesh link with other
radios in the system. When establishing a mesh the radio sends out a broadcast
message and then monitors the signal strength from all other nodes that respond,
if any of the signal levels are below the “Receive Signal Strength Threshold” the
mesh link will be ignored. This threshold is used in conjunction with the “Link
Quality Threshold” above
Configures the time the unit will back off if a route request to another unit fails. If the

IP Routing
When a M1115NL receives an IP frame that is destined for an IP address on a different network, it checks to see if the
network address matches one of its own interfaces (i.e. hard-wired Ethernet, or Radio) and forwards the frame
appropriately. However, if the IP network address does not match the network address of any of its interfaces, the
M1115NL will forward the frame to its default gateway. In this case it is assumed that the default gateway has a valid
route to the destination.
In some cases, it is not practical to have just one default gateway (i.e. routed wireless networks with more than two
M1115NL routers. If more than one “next-hop router” is required, the M1115NL allows for up to 100 routing rules to be
configured. A routing rule specifies a destination network (or host) IP address and the corresponding next-hop router
that messages for the specified destination will be forwarded to (Gateway). It is assumed that the Gateway will then
deliver the data to the required destination (or forward it on to another router that will).

Mesh Fixed Routes
In large radio systems there will often be a number of radios that will act as Repeaters for the other radios. Because
these sites are generally stationary they do not need to learn the different paths and can have fixed routes back to the
destination. We configure these routes with Mesh Fixed Route Rules.
You can configure up to 100 fixed Route Rules for each site and the rules can be targeted to a specific IP address by
using a Host Route or a complete Subnet.
Example #1
Figure 47 - Mesh Fixed Route #1
The Network Diagram above shows a typical network with mesh fixed routes. Normally a meshing network will
automatically learn the routes within a network and setup appropriate communication paths to the destination. When
manually configuring these routes all communication paths need to be setup by using Mesh Fixed Routing Rules.

Figure 48 above show the Mesh Fixed Routing Rules for the network diagram in Figure 47 above.
In fixed Route #1 it shows the Destination IP Address will be 10.0.0.1 and its Next hop will be 10.0.0.2, there will be a
total of 2 hops and the ”IP Gateway” and “External” are un ticked as the destination will be the local I/O on 10.0.0.1.
In Route #2 is a route showing the communication path with repeater #2. The destination and next addresses are both
10.0.0.2 because it’s a single hop and again the “IP Gateway” and “External” are un ticked as the communications is
all local and not through a Gateway or out of the mesh.
Example #2
Figure 49 Mesh Fixed Route #2
Figure 50 - Mesh Fixed Route #2 Routing Rules
Figure 50 shows the routing rules for the network diagram Figure 49- Mesh Fixed Route #2” above
The first route shows the destination and next addresses are both 10.0.0.1 as it’s a single hop. Because the
destination is a Gateway on an external network the IP Gateway must be enabled.
The second routing rules shows the Destination (192.168.1.100) is an external network and is outside of the radio
mesh, therefore the External tick box must be enabled. The next address will be 10.0.0.1, which is the IP Gateway.

WIBMesh is an extremely efficient proprietary radio protocol used for radio communications. The protocol is based on
the “Ad hoc On Demand Distance Vector” (AODV) routing algorithm which is a routing protocol designed for ad hoc
networks. There is very little configuration for the WIBMesh as the protocol automatically routes through the mesh to
the destination.

TX Attempts for
Acknowledged messages
How many times the configured module will attempt to communicate a
message to another module (message reties).
After failing to communicate the module will be flagged as being in comms fail.
If it tries to communicate to the remote module again, it will reduce the number
of attempts down to one as it has been flagged as being in Comms fail.
If communications is restored the module will go back to transmitting the
number of time configured in “Tx Attempts for Acknowledged messages”.
TX count for
unacknowledged
messages
The number of times it transmits the same data message. It is used if the
M1115NL has been setup as a transmit only module (similar to the older DAWN
WIreless 905U-K or 505U-K modules). It is done by not selecting the “Ack” tick
box in any Block Write and Gather/Scatter Block mappings. (See 0 “WIBMesh
Mappings” below)
Being a Transmit only module there is no communication handshake between
modules so transmitting the same message a number of times gives a greater
reliability in communications.

Sensitivity Block
Figure 56 - Sensitivity Block
All registers have a configurable “Sensitivity” value, which determines how much the register needs to change by
before being sent as a “Change of State” (COS).
All registers have a default sensitivity value of 1 except the following.
The 12 analog inputs have a sensitivity of 1000 (3.2%) and the 24 floating point values will have a default sensitivity
of 0.5 units. In the case of 38001 – 38004 this will be 0.5mA, in the case of 38005-38012 it will be Volts and in 38013
– 38016 it will be Hertz. (The reason is so the module does not send every single bit change of an analog value and
subsequently saturate the radio channel with unwanted change messages.
If a lower sensitivity is required then the above blocks can be adjusted and up to 48 more Sensitivity Blocks can be
configured for different registers or different values.
They are configured as per the table below

(32768), which would represent about 3%

table.
E.g
Digital input #1 on an 115S-11 (address 5) would be: (5x20) + 10001 = 100 + 10001 = 10100
Digital output #2 on an 115S-11 (address 6) would be: (6x20) + 2 = 120 + 2= 121
Analog input #3 on an 115S-12 (address 3) would be: (3x20) + 30003 = 60 + 30003 = 30063.
Analog Output #8 on an 115S-13 (address 7) would be: (7x20) + 40007 = 140 + 40007 = 40146

Fail Safe Configuration
Fail Safe Block configuration allows registers to be set to a pre configured value on startup as well as configuring the
outputs to reset to a predefined value after a timeout period has elapsed, when the real value comes in it will update
as normal. Also if the value is lost because of a communication problem it can be configured to set the output to a
failsafe value after the pre-configured time.
“Invalid” register state
Figure 57 - Invalid Register State
All registers within the module can have various states depending on what type of register it is and what sort of value
it holds, an analog would be between 0 and the maximum 65535, a digital can be 0 or 1, etc.
All registers that are not associated with any physical I/O have another state which we call “invalid”, this state means
that the value has not been written to and so does not hold a value but more a non value or null.
If you were to read the registers using the “I/O Diagnostics” an invalid register would read “~“as shown in Figure 57
above.
Any mapping with an invalid register will be inhibited from sending. This is to ensure the data that gets to
the destination is valid and not just default values that the module starts up with. Refer to section 0“Fail Safe
Blocks” below for a way of giving registers a valid value at start-up

Fail Safe Blocks
Figure 58 - Fail Safe Blocks
In the screen shot above, register 30501 is an analog value that has been mapped from another module, it has an
update interval of 1 minute.
On startup this module will write a value of 16535 into register 30501 and then start counting down from the “Timeout”
value (in this case 600 seconds).
If after 600 seconds, the module still has not received an update from the other module, register 30501 will be set to
the “Fail Value” (in this case 0).
If the “Invalidate on Fail” were ticked, the value would be set to a null or invalidated value (-).
If this register was mapped to some other location the mapping would be inhibited until the” Invalid” value was
updated with a real value.
The maximum number of Fail Safe blocks you can have is 50.

Serial Configuration
The M1115NL has an RS-232, and an RS-485 port for serial communications. These ports may be used to connect
external Modbus RTU devices via the Modbus TCP to RTU Gateway and or DAWN WIreless serial expansion I/O
modules.
Modbus TCP to RTU Gateway
The Modbus TCP to RTU Gateway allows an Ethernet Modbus/TCP Client (Master) to communicate with a serial
Modbus RTU Slave. The M1115NL makes this possible by internally performing the necessary protocol conversion.
The conversion is always performed by the M1115NL, which is directly connected to the Modbus serial device (i.e.
only this module needs to have Modbus TCP to RTU Gateway enabled).
The example below demonstrates how a Modbus/TCP Client (Master) can connect to one or more Modbus RTU (i.e.
serial) Slaves. In this example the remote M1115NL is configured with the “RS232 Modbus/TCP to RTU Gateway”
enabled

Once enabled, the gateway converts the Modbus/TCP queries received from the Master into Modbus RTU queries
and forwards these over the RS232 port to the Slave.
When the serial response to the query arrives from the Slave, it is converted to a Modbus/TCP response and
forwarded via the network to the Modbus/TCP Master. If no response was received serially by the M1115NL within
the configured Response Timeout, the M1115NL will initiate a number of retries specified by the configured Maximum
Request Retries.
The Modbus TCP to RTU Gateway may be configured to operate on either the RS 232 or RS 485 port.

Expansion I/O
By default the RS485 port will be automatically enabled for “Expansion I/O “.
This means that when expanding the I/O all that is needed is to add the DAWN WIreless Expansion I/O module/s, e.g.
115S-11, 115S-12, or 115S-13 to the RS485 port and the I/O will automatically be available from within the M1115NL’s
I/O store. See Appendix B: “I/O Store Registers” for location addresses.
By default the Data Rate, Data Format will all be standard 9600, N81 and none for Flow Control which matches the
default Serial baud rate and data Format of the 115S serial expansion module.
Serial parameters can be adjusted for compatibility or faster serial performance by adjusting the rates and format and
then selecting the “Save and Activate” Button.
Serial port parameters will also need to be changed on the expansion I/O module by using the 115S Configuration
Utility which can be downloaded from the DAWN WIreless Technologies Website (www.dawnwirelesstech.com)
Note: Be aware that using settings other than the default will mean new modules from the factory will require
a reconfigure using the 115S configuration utility to change these serial settings.

Analog Inputs
Figure 62 - Analog Input Configuration
The M1115NL Analog inputs have the following configuration parameters.
Name – The inputs can be named to help with configuration or use the default, up to 30 characters including spaces.
Zero / Span – These variables will change the Scale of the Analog Inputs.
Zero – Starting Value (counts) when measured value is zero
Span – Number of counts per measured value (mA, V, Hz, etc)
Filter (sec) – The Filter time Constant is the time the analog takes to settle on a step changed of an analog value. By
default, all the inputs except the Pulse Rates have a Time constant of 5 seconds. Pulsed input rates are not filtered.
Lower & Upper Setpoints – The Setpoint is a discrete signal that is controlled using the Upper and Lower Setpoints,
Invert and Window selection boxes. All the analogs have these controls and they can be used to turn on an output
locally or at a remote location. The internal setpoint status must be mapped to a remote output for this option to have
effect.
The two main Setpoint control options are.
• Deadband (Default) - If the Analog Input is greater than the Upper Set point, the set-point status will be active (on,
“1”). The setpoint will reset (off, “0”) when the Analog Input is less than the Lower Set Point. Note that the Upper
Set Point must always be higher than the Lower Set Point.”
• Windowed – If the analog value is inside the upper and lower setpoints, the setpoint will be active (on, “1”), and if
the analog value is outside of these setpoints the setpoint will be reset (off, “0”)

Invert –This option toggles the Setpoint control logic between the default normal and inverted state. This function does
not change the operation, only invert the operation, e.g. if setpoint is on, inverting will mean the setpoint will be off.
Window – This option toggles the Set point operation between the default Deadband and Windowed modes.
The Analog is a 16-bit word that has an overall Raw range of 8192 to 49152 decimal (Total = 32768). The input
Engineering range can have many different forms i.e. 0-20mA, 0-5V, or 0-1000Hz which is why the zero and span can
be scaled to give the correct Raw range.
Calculating Span
The Span us calculated by using the formula
Span = DAWN WIreless Raw Range / Engineering Range
The Raw range is the number of counts between minimum and maximum analog values. DAWN WIreless standard is
minimum= 8192 and maximum value is 49152 so the Range is 40960 counts (49152-8192).
The Engineering range will be the range of engineering units – 1-20mA = 20, 0-5V = 5
Some example Span calcs - If the Engineering range is 0-20mA (20) the Span would be 2048 (40960/20).
If the Engineering range is 0-5V (5) the Span would be 8192 (40960/5)
Calculating Zero
The zero is calculated by using the formula Zero = Raw DAWN WIreless Scale – (Engineering Value x Span).
E.g. If the Engineering Range is 0-20mA the Engineering value will be 20. The span from the 0-20mA
calculation above was 2048 therefore the Zero calculation will be 49152 – (20x2048) = 8192
For a 0-5V input the Engineering Value will be 5, the Span from the 0-5V calculation above was 8192 therefore
the Zero calculation will be 49152 – (5x8192) = 8192

Failsafe Time (sec) – The Fail Safe Time is the time the output needs to count down before activating the failsafe
state. Receiving an update or a COS message will reset the Fail Safe Timer back to its starting value. If the Fail Safe
Timer gets down to zero then the output will be set to the Fail Safe state (mA)
It is recommend this Fail Safe Time be configured for a little more than twice the update time of the input that is
mapped to it, that way the output will reset if it fails to receive two update messages. Entering a zero in the Fail Safe
Time will disable.
Failsafe value (mA) – The value that you wish the output to be set to on activation of the failsafe timeout.

Name – The inputs can be named to help with configuration or use the default, up to 30 characters including spaces.
Debounce Time (sec) – Debounce is the time which an input must stay stable before the module decides that
a change of state has occurred. If a digital input changes (on - off) and changes again (off - on) in less than the
debounce time, then the module will ignore both changes. Default debounce time is .5 seconds.

Failsafe Time (sec) – The Fail Safe Time is the time the output needs to count down before activating the failsafe
state. Receiving an update or a COS message will reset the Fail Safe Timer back to its starting value. If the Fail Safe
Timer gets down to zero then the output will be set to the Fail Safe state (ON or OFF)
It is recommend this Fail Safe Time be configured for a little more than twice the update time of the input that is
mapped to it, that way the output will reset if it fails to receive two update messages.
Fail Safe State – The value that you wish the output to be set to on activation. Checking the box will turn the output
ON when a failure occurs and un-checking the box will turn the output OFF.
Pulsed Outputs
Figure 66 - Pulsed Output Configuration
Name – The inputs can be named to help with configuration or use the default, up to 30 characters including spaces.
Update Time (sec) – Time that the output will be updated with the latest received value. The time is related to the
update time of the pulsed input that is mapped to it. E.g. If the pulsed input update time is configured for 10 seconds
the number of pulses will be counted and send to the receiving module every 10 seconds. The receiving module will
then output the pulse count over the configured update time, i.e.10 seconds
Modbus TCP Transfer
The M1115NL provides Modbus TCP Client and Modbus TCP Server functionality for I/O transfer. There are predefined areas representing Inputs and Outputs as well as the different I/O types, e.g. Bits, Words, Long, Floats, etc,
which include the onboard Input/Output) and are shared for both Client and Server. For a full list of the available I/O
and
address, locations please see Appendix B: “I/O Store Registers” at the end of this document.
Modbus TCP Client (Master) and Modbus TCP Server (Slave) are both supported simultaneously, and when
combined with the built in Modbus TCP to RTU Gateway the M1115NL can transfer I/O to/from almost any
combination of Modbus TCP or RTU devices.
Modbus TCP Server (Slave) enables the M1115NL to accept connections from one or more Modbus TCP Clients
(Masters). All Modbus transactions routed to the onboard Modbus TCP Server are directed either to/from the onboard
general purpose I/O registers. The Modbus TCP Server is shared with the Modbus TCP to RTU Gateway, so that the
Modbus “Device ID” is used to determine if a Modbus transaction is to be routed to the onboard Modbus TCP Server
or to a Modbus RTU device connected to the serial port. Care should therefore be taken that all serially connected
Modbus devices use a different Modbus Device ID (i.e. Modbus Slave Address) to the onboard Modbus TCP Server.
Up to 32 separate connections to the Modbus TCP Server are supported.

Figure 67 - Modbus Server
Modbus TCP Client (Master) enables the M1115NL to connect to one or more Modbus TCP Servers (Slaves).
All Modbus Master messages are directed either to/from the onboard I/O registers depending on configuration
(described below). The Modbus TCP Client may also poll Modbus TCP (Ethernet) and Modbus RTU (serial) devices
connected to either the local module or a remote M1115NL module. This is done by enabling the Modbus TCP to RTU
gateway at the corresponding serial port (see section 0“Serial Configuration”).
Figure 68 - Modbus Client
Modbus TCP Client functionality allows connections to a maximum of 24 different Modbus TCP Servers and up to 100
mappings can be configured.
The screen shot shows below some example Client Mappings.
Figure 69 - Modbus TCP Client Mappings
The first mapping shows the Modbus Client (Master) is configured to read analog values from a device connected on
the LAN. The mappings function code is “04 Read Inputs” and is reading a count of 4 values (Analogs) from Ethernet
IP address 192,168.0.10, Device ID #10, starting at address 1, and then writing these values into its own local
registers starting at 30501. The server Port is 502, which is a standard Modbus TCP Port address.
Note: Destination Registers start at zero as the offset is calculated from the Modbus Function Code, e.g. 3X,
4X, 1X, etc.

The next mapping shows something similar however, instead of analog value they are digital values. The Function
code is “02 Read Discretes” again from IP address 192.168.0.10 and Device ID #10. It will read 8 values starting from
address 1 and writing them to the local address starting at 10501.
The third mapping is similar to the second however, instead of reading from an Ethernet device it will read from a
Serial device connected to the local RS485 port.
Mapping shows a function code “02: Read Discretes” from Device ID #5 connected to the Localhost IP address
127.0.0.1 (*Note) It is reading 8 values from address 1 and then writing these values to local register 10509. One
main difference is that the Server Port is configured for 504, which is the port number assigned for serial RS485
devices, Port 503 can also be used if using devices on the RS232
The last mapping shows the Modbus Client can also write values to Modbus devices either on serial or TCP. This
mapping is setup to “Write Coils” with an I/O Count of 8 from the local address 10501 to Device 10 on Server IP
address 192.168.0.10 at address location 4.
The Modbus Client Scan rate is set to 1000msec (see Figure 68 above) and each mapping is configured with a
response timeout (in this case 2000msec). This time is how long the master will wait for a response before indicating
the failure on the Comms Fail Register. (In this example register 8 -5 are register for local digital outputs 8 – 5)
*Note: The IP address 127.0.0.1 is a standard loopback address that represents “localhost” (this computer). Using the
loopback address will mean if the module address is ever changed the Server IP address will not need to be changed
as it will automatically use the localhost address.

Appendix F: GNU Free Document Licence
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU
General Public License is intended to guarantee your freedom to share and change free software--to make sure
the software is free for all its users. This General Public License applies to most of the Free Software Foundation’s
software and to any other program whose authors commit to using it. (Some other Free Software Foundation software
is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to
make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that
you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to
surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the
software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the
rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them
these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the software.
Also, for each author’s protection and ours, we want to make certain that everyone understands that there is no
warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to
know that what they have is not the original, so that any problems introduced by others will not reflect on the original
authors’ reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors
of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we
have made it clear that any patent must be licensed for everyone’s free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it
may be distributed under the terms of this General Public License. The “Program”, below, refers to any such program
or work, and a “work based on the Program” means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated
into another language. (Hereinafter, translation is included without limitation in the term “modification”.) Each licensee
is addressed as “you”.
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope.
The act of running the Program is not restricted, and the output from the Program is covered only if its contents
constitute a work based on the Program (independent of having been made by running the Program). Whether that is
true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program’s source code as you receive it, in any medium, provided
that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty;
keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of
the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in
exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program,
and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of
these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any
change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program
or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for
such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright
notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute
the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program
itself is interactive but does not normally print such an announcement, your work based on the Program is not required to
print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the
Program, and can be reasonably considered independent and separate works in themselves, then this License, and its
terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms
of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part
regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent
is to exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the
Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the
terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to
be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative
is allowed only for noncommercial distribution and only if you received the program in object code or executable form with
such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an executable work,
complete source code means all the source code for all modules it contains, plus any associated interface definition files,
plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source
code distributed need not include anything that is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering
equivalent access to copy the source code from the same place counts as distribution of the source code, even though
third parties are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights
under this License. However, parties who have received copies, or rights, from you under this License will not have their
licenses terminated so long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission
to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this
License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your
acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or
works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a
license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may
not impose any further restrictions on the recipients’ exercise of the rights granted herein. You are not responsible for
enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to
patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to
satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the
Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and
this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section
is intended to apply and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity
of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system,
which is implemented by public license practices. Many people have made generous contributions to the wide range of
software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to
decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted
interfaces, the original copyright holder who places the Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to
time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or
concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this License which
applies to it and “any later version”, you have the option of following the terms and conditions either of that version or of
any later version published by the Free Software Foundation. If the Program does not specify a version number of this
License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different,
write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to
the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software
generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM,
TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT
HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED
ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR
THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
