Quick SETUP
This section shows you how to configure and run the device within 5 minutes. We presume you are
using the “Poseidon standard set“, which consists of one Poseidon + one 1-Wire temperature sensor.
If you are using other sensors as well, see the end of this section r to learn how to connect them to
the Poseidon.
Information on connecting other sensors and more is described in the detailed section on device
configuration. If you encounter any problems, go to that section, which describes the device's
configuration step by step.
1) Cable connection
•
Copy down the MAC address of the device from the plate on the bottom of the case.
•
Set DIP1=Off, DIP2=ON, DIP3=Off, DIP4=Off
•
Connect the 1-Wire type temperature sensor to Port 1 (Cannon 9 Female)
•
Connect the Poseidon to your Ethernet network. If you are connecting to a switch or hub, use
a normal patch cable. Alternatively, you can connect it directly to a PC with a crossover cable.
•
Connect supplied power adaptor to an outlet and plug it into the Poseidon
•
The green POWER indicator on the Poseidon will light up
•
If the Ethernet connection is OK the green LINK indicator will also light up. It will flicker
according to the activity on the LAN, letting you see what activity is present.
2) IP Address Setup
•
Run
the
“HerculesSetup.exe“
application which can be found in
the root directory of the CD which
comes with the Poseidon. It can also
be
downloaded
from
www.HWgroup.cz
•
(A) In the “UDP Setup“ tab, click on
the “Find Devices“ button. The
device’s MAC address will appear in
the left column (B).
•
Click once on the MAC address (B)
(it should be identical with the
number from the plate on the
device).
•
(C) Set the desired parameters (at
least IP address, Mask and
GateWay).
•
(D) Click the “Apply Changes“ button to assign the new IP address and other parameters to
the device. The device will now restart, which will make it disappear from the list of MAC
addresses for a while).
•
Click on the (A) “Find devices“ button again and check the parameters are set correctly.
•
Click on the (E) “TCP Setup configuration“ button to begin to configure the Poseidon for the
sensors. (Next step).

3) Configuring Poseidon for the connected sensors
•
In the “UDP Setup“ tab choose the (E) “TCP Setup configuration. This will open the
configuration of connected sensors. You can also turn to the “TCP Client“ tab and connect
to the device’s IP address and port 99. (The port value can be changed in the setup).
•
In the screenshot below you can see the connection and prompts for “User name” and
password. There is no name or password, so just press the Enter key twice .
•
When you receive the “Are you sure to enter setup?“ prompt press “y“ and then the Enter
key. You’ll get a menu, which you can see on the screenshot.
•
Press the „1“ key and confirm the autodetection request by pressing “y”. The Poseidon will
search for connected sensors and list the number of sensors found on the 1-Wire MicroLan:
„Searching ... 1 sensors found“.
•
Accept the number of sensors found by pressing the Enter key, which cause the menu to be
written once more including the actual type and number of sensors.
•
Each 1-Wire sensor has a unique internal ID. If you change or add a sensor, you must run
this autodetection process again!
•
•
Exit the TCP Setup by pressing the “x“ key.
Change back to the “UDP Setup“ tab. Click the (F) “Open in the WEB Browser“ button to
open
the
WWW
pages
of
the

4) Device’s Webpage
Poseidon allows immediate display of the
“index.htm“. It is served as the main page
of the device.
•
On the screenshot you can see the
device’s Web page with the values
received from a 1-Wire temperature
sensor. The page refreshes every 5
seconds.
•
Connect the binary (digital) input 3
(two side brackets) with a piece of
wire and, after the page refreshes,
you will see that the value of the
binary input has changed.
•
Notice the bottom line where you
can see the default text “Detailed
values it is seeing via the webpage it generates,
information can be found on
www.hwgroup.cz“. This can be
changed in the Setup so it would
bear the text of your choice – the
name of your company for example.
•
Click on the “Graphic Flash SETUP“
to open the graphic configuration
interface (Flash Setup).
5) Graphic Flash Setup of the device
To open the FLASH page, you must have the FLASH applications support installed on your PC. If
you have access to Internet, the required plug-in will be downloaded automatically. If not, you can
install the plug-in from the supplied CD - \Poseidon\install_flash_player_7.msi
•
In the first tab, called
“General“, you can see a
summaryof the sensor
values. If you wish to have
them checked regularly,
switch to the “Refresh” tab,
set the desired time and
press the “Start” button.
Now the values will
automatically and regularly
refresh.

Troubleshooting
•
You didn't find the device’s MAC address in the list?
If the LINK indicator hasn’t lit up or the device does not respond, check the following possible
causes.
1. Does your Ethernet network support 10 Mbit devices?
2. Are you using the proper TP cable (direct “TP Patch“ cable for connection to an Ethernet
switch or router, or a crossover cable for direct connection of a Poseidon to a PC.)
3. Check DIP configuration (all should be in the OFF position).
4. Check that the Power indicator of the power adaptor is lit.
•
You can't open the TCP Setup?
You can find the device using the “UDP Setup” tab, but the connection after pressing the
“TCP Setup” button does not work?
5. If you changed the port number to something other than the default 99, you have to switch to
the “TCP Client” tab and set the IP address and port number manually.
6. If you didn’t change the port number and it still does not work, try using the RS-232 Setup
mode over a LapLink (or null modem) cable and the “RS-232” tab (see below).
Connecting RS-485 sensors
•
Connect the Temp-485 or HTemp-485 sensor to Port 1.
•
If the wiring is longer than about 2 meters, put a proper RS-485 terminator on the end of the
line. Some sensors (e.g. Temp-485) include a terminator, which can be connected by an
internal switch or jumper.
•
Set the sensor’s address using the jumpers on the sensor. Use an address which no other
sensor on this RS-485 line uses. If working with a sensor with no configuration jumpers, you
will find the default address on the plate placed on the sensor or you can assign the address
as described in the relevant part of this manual.
•
Check that you have set the DIP2=ON, which enables RS-485 on Port 1.
•
Run the TCP Setup on the port 99 (DIP3=Off) and go to the main menu.
•
Choose the option (3).. RS-485(Temp-485) and run the sensor autodetection, which will
write out the RS-485 addresses of all found sensors. If Poseidon writes out the same
address as you have set, then everything’s all right.
•
Press “x” to eXit the Setup mode. Open the device’s web page.
•
On the web page you should see the value the sensor. The operation of the sensor is bound
to its RS-485 address, so two sensors with the same address can be swapped freely without
having to change the Poseidon’s configuration.

Device description
MAC Address
Mac address is a unique number identifying the
device. It can be found at the bottom of the case.
00:0A:59:XX:XX:XX
The MAC address always consists of six pairs of
characters. The first three pairs are always 00:0A:59; the rest
is written on the plate.
Power supply connector
Classical coaxial power supply connector with the internal pin diameter of 2,5 mm.
The negative pole is on the connector shield.
We can supply a version connecting the power via a connector on the terminal board.
Ethernet
The Ethernet network interface is pinned out to the standard RJ45 connector
and connected by a Twisted Pair (TP) cable to a switch or router. A crossover
cable may be used to connect directly to a PC.
The device does not have PoE (Power over Ethernet) support. It is only
equipped with 10Mbit Ethernet, so it can be connected to 10 Mbit or 10/100
Mbit networks only.
Note:
HW group
The device cannot be connected directly to a 100 Mbit network! If you need to connect
it to a 100 Mbit (or faster) network, use 10/100 Mbit Ethernet switch.

blinks. The Ethernet is not available
DIP2 - Port 1 RS-232/485
If DIP2 is set to the OFF position, no sensors connected over the RS-485 bus on Port 1 can be used
because Port 1 is switched to the RS-232 mode. For that reason, use the default configuration:
DIP2=ON.
DIP3 - Security protection
If the DIP3=ON, the Security protection mode is active. In this mode any remote configuration is
forbidden:
•
The configuration cannot be changed using the UDP Setup (Hercules program)
•
The Flash Setup can be opened in the Internet browser but the configuration can’t be

1-Wire (MicroLan)
Pinned out to:
Port 1 [ (4) 1-Wire, (5) GND, (6) +5V]
1-Wire is a busbar of the Dallas Semiconductor company, intended for connection of several sensors
over short conduct. The bus only contains a power supply and one data conductor. It is not though
intended for long distances, not even for conducts in places with an EMC jamming.
The manufacturer recommends conducting at most to 10 meters, though in terms of experiments
there are cases of bus bar operating within tens or even hundreds of meters but for conduct longer
then 15 meters there is no guarantee of an errorless function, which then consists in a wiring
construction and topology of conduct and environment where the conduct is installed etc.
If you need to extend the conduct’s reach, see the original manual and use recommended cable
connection, termination resistor and filtration capacity at the end of the conduct for power supply
stabilisation.
Warning:
The guarantee of the Poseidon device does not cover malfunctions caused by
using 1-Wire sensors from other sources or excessively long wiring for these
sensors.
Remember:
All 1-Wire devices are equipped with a fixed, unique, internal serial number. It is
recorded during sensor detection. If you change your sensor,you must reconfigure your Poseidon, using the function (1) 1-Wire > Autodetection in the
TCP Setup or RS-232 Setup mode!
RS-232
Pinned out to:
Port 1 DB9F [ (2) TxD, (3) RxD, (5) GND, (7) CTS, (8) RTS]
The interface is intended for setting the device (RS-232 Setup, if DIP1=ON) or eventually for loading
a new device’s FirmWare (FW update possible only using the Port 1).
RS-485
Pinned out to:
Port 1 DB9F [ (1) A (+) RS-485, (5) GND, (8) +12V, (9) B (-) RS-485]
The RS-485 interface is a professional industrial busbar according to the standards for using in an
industry and telecommunications.

The disadvantage of the bus, if you want to go beyond 20 meters, is that you need to connect with
one start and one end. You cannot use the popular Y, or star topology with one or more junction
points. If the application requires such topology, we recommend using two twisted pairs, connected at
the end device but in the central junction point they’ll be defined as an input and an output.
The end of the RS-485 line must be terminated. Some sensors, (e.g. Temp-485) have terminators
built into them, which are connected to the line if needed with an internal link or jumper. Otherwise,
you must using an external resistor connectedat the end of the line as shown. This resistance should
not be less than 120Ω, but for short lines, the termination resistance can be up to 470 Ω . This will
reduce e the circuit's power demand.

Port 2
Port 2 only contains the RS-232 interface connected to
the Cannon 9 Male connector. The pinout is analogous
to that of a PC. For connection to a PC use crossed
LapLink cable (DB9F – DB9F) (see diagram below.).
Port is used for following purposes:
•
RS-232 Setup (DIP1=ON)
•
Temp-232 sensor connection
•
Connection to the DTR and RTS binary
(digital) outputs (DTR output cannot be used
at the same time as a Temp-232 sensor).

To respect the standards of the RS-232 interface, sensors should only be up to 20 meters from the
Poseidon. However, because of the low baud rate used, (9600 8N1), there is good experience with
connections of up to 50 meters. The main disadvantage of using Port 2 is that only one temperature
sensor can be connected... at the moment.
Using DTR and RTS digital outputs
Voltage level on the DTR and RTS outputs can be controlled via SNMP commands. When the device
first powers up, the outputs are set as follows:
•
RTS: OFF (-3 .. -15V)
•
DTR: ON (+3 .. +15V)

Poseidon’s capabilities – system schematic
You can connect temperature and humidity sensors to the RS-485 serial line. The line can be as long
as 1,000 meters. With converters, you can also connect sensors with current loop outputs, or Pt
resistor temperature sensors, e.g. the Pt100, Pt500, or Pt1000.
Sensors’ interface - 3 Binary inputs
3 binary digital inputs with common ground are connected to the front terminal block and are primarily
for connecting closing or opening contacts. The inputs are isolated from the rest of the Poseidon by
opto-isolators.” The wires to the switches can be tens of meters long.
Sensor interface - RS-232
RS-232 is a specification for a serial connection between devices. It is what the serial port of a PC
uses. The official standard for RS-232 says that the cable should be limited to 15 meters. The
interface is not entirely suitable for connecting sensors in an industrial environment. The interface is
primarily intended for configuring the Poseidon or for connecting of one temperature sensor. Using
the RS-232 on Port 2 you can set, in RS-232 Setup mode, the parameters of the Ethernet interface
(module IP address, network mask, default gateway). The rest of the configuration can then be done
using more convenient WWW/FLASH interface. It is not always necessary to do anything via the
serial interface.
Sensor interface – 1-Wire
1-Wire (also known as Microlan) is a simple bus for connecting up to 10 digital temperature sensors
(DS18B20 / DS18B22) to the Poseidon. A three conductor cable is used. It can be up to 15m long.
Longer cable runs will work if care is taken over several points.
Sensor interface - RS-485
The RS-485 interface is primarily intended for connecting measuring sensors and allows connecting
several sensors to a common bus which can be 1000 meters long. There are temperature and humidity
sensors designed for the RS-485 bus. A list of sensors available from HW Group can be found at the end
of this document.
Up to 5 sensors on the RS-485 can be powered directly from the Poseidon’s Port 1. If you plan to use
longer wiring or more sensors, we recommend using an external power supply.

Modbus over TCP
Modbus is a communication protocol designed for measuring devices
communicating via RS-485 or RS-232. The Modbus protocol itself
allows sharing the variables’ storage zone over one of the physical
interfaces, from measuring values for instance. Modbus/TCP thus represents the expansion of this
protocol for Ethernet communication.
The advantage is easy implementation of visualization systems for industrial use.

SNMP – interface description
SNMP (Simple Network Management Protocol) is suitable for primary
system information exchange using short packets sent via UDP/IP.
Individual variables are organized and described in the so-called MIB
(Management Information Base) table, which can be used for any device.
The table is distributed as a separate .mib file, which can be downloaded to
the Poseidon from our web pages or found on the supplied CD.
SNMP is an asynchronous protocol based on the client/server model (here SNMP Client/SNMP
Agent). That means the supervisor (SNMP Client) queries the Poseidon for the state of the individual
values in the MIB held in the Poseidong and the SNPM Agent, implemented in the Poseidon,
responds.
SNMP protocol support is provided in many languages intended for creating dynamic WWW pages
(e.g. PHP, ASP, Java, Perl, Python and others). Thanks to existing modules it’s possible to allow
access read or write to the data in the MIB in system peripheral device (e.g. a Poseidon), over the
SNMP protocol quite quickly.
In classic communication mode the communication proceeds in terms of queries and responses. The
variables are defined by a numeric string, which is described in the MIB table which also defines the
meanings of the individual variables, format and names. If you know the hierarchy (numeric string –
e. g. „.1.3.6.1.4.1.21796.3.3.1.1.2.3“ – state of binary input 3) for a specific value, you don’t need the
MIB
table.
Before we go any further, it will be helpful to define two basic terms:
•
MIB table – .mib file is a text-based file, describing individual variables supported by the
device. In this, addresses of variables, their names, description and numeric format is
defined.
•
OID is an identifier of the variable in the variables’ chart. It’s represented by a long number,
defining the variable’s position within the variable tree structure.
Some programs do not support MIB files for working with SNMP. Then you must enter OID strings
manually. The strings can be found in the MIB tab, but for your easier orientation we indicate a
summary of several variables including their OID:
Where to find the actual MIB table

MIB table can be found on the supplied CD: /Poseidon/poseidon.mib

SNMP traps (alarms) – interface description
If any of thermometer’s (or digital input's) value gets out
of the “non-alarming” range defined for it by Setup, that
sensor / input will switch to the ALARMING state. When
the state changes (to ALARMING, or back to NOTALARMING, the Poseidon will announce the event by
sending an SNMP trap to the IP address specified
(again by Setup) to receive SNMP traps.
The trap consists of two UDP packets, sent by the Poseidon (SNMP Agent) to the preset
supervisory centre (SNMP Client). The details of the packet format is contained in the MIB table. The
first packet announces the change of state. The second packet provides additional information such
as which sensor has gone into or out of it's ALARM state.
The trap system was developed to speeding up delivery of information about changes of state
because in the classic SNMP mode didn't do the job well. In the Classic system, the supervisory
centre sent out queries to the client (Poseidon) on a schedule determined by the supervisory centre.
If it only queried the Agent every 10 minutes, then the change of state in the Poseidon might have
happened almost 10 minutes before the supervisory centre learnt of the change.
For the digital inputs,. it is possible to define Open or Closed as the “ALARM” state. Thus, you can
arrange for the Poseidon to send traps when the state of the input changes. You do not need to do
this, however, so if you do not want traps arising because of changes in the digital inputs, you do not
need to have them.
SNMP Traps sent from Poseidon
The list and detailed description of SNMP Traps can be found in the MIB table, here you will find just
a general description.
•
Cold Start + Link Up Trap
Pairs of SNMP Traps, sent after turning on the device. If there is an Alarm on any device at
the moment of startup, the sensor immediately sends other trap pairs.
•
Alarm started from the binary input
Pair of SNMP Traps sent after Alarm started on a binary input. The first Trap contains the
identification of the started alarm for an “alarm table” attendance. The second SNMP Trap in
its body already contains for example the name of the binary input, which started the alarm.
•
Finished Alarm from the binary input
Pair of SNMP Traps sent when an alarm state ends. This pair will always have been
preceded by a pair announcing the start of an ALARMING state. The first Trap contains the
identification of the started alarm for an “alarm table” attendance. The second SNMP Trap in
its body already contains, for example, the name of the binary input, which has stopped
alarming.
•
Alarm started from the value sensor
Pair of SNMP Traps sent after starting the Alarm state for a value sensor (temperature,
humidity and other). The alarm will be set off if any value occurs outside the “non-alarming”
range which has been set for that sensor, but there is also a hysteresis setting which will
prevent “chatter” as the temperature passes through the alarming range boundary.. The first
Trap contains the identification of the started alarm for an “alarm table” attendance. The
second SNMP Trap in its body already contains, for example, the name assigned to the
sensor and the value that started the alarm.

HW group
Finished Alarm from the value sensor
Pair of SNMP Traps sent after ending the Alarm state of the value sensor (temperature,
humidity and others). The alarm will be turned off as soon as a value within the “nonalarming” range for that sensor occurs, but there is also a hysteresis setting which will
prevent “chatter” as the temperature passes through the alarming range boundary.. The first
Trap contains the identification of the started alarm for an “alarm table” attendance. The
second SNMP Trap in its body already contains, for example, the name assigned to the
sensor and the value that ended the alarm.
Detailed configuration description
This chapter contains detailed description of the possible device configuration and their importance.
All options described are valid for firmware version 1.X
Assigning a proper IP address to the device
All of the Poseidon’s operating parameters can be set using the FLASH interface but first it is
necessary to configure manually the network parameters. Until that is done, you won’t be able to run
the web interface. The primary configuration of the Poseidon’s Ethernet parameters (IP address,
network mask, gateway) can be done by either of the following methods:
•
By means of UDP Broadcast using the Hercules Setup Utility, which can be found on the
Internet or in the root directory of the supplied CD. This method can only be used when using
Windows and it may not work for all networks because of firewall settings.
•
By using RS-232 Set-up and any serial terminal at speed of 9600 8N1. A PC running
Hyperterminal (which comes with Windows) is fine. The connection should be via a LapLink
cable, or null modem cable (see diagram elsewhere), connected to the Poseidon's Port 2.
Entering the RS-232 Setup mode
•
Set DIP1 = ON and DIP2 - DIP4 to the OFF position
•
Connect the standard package of the 1-Wire thermal sensor to the Poseidon (Port 1)
•
Connect the supplied LapLink
cable to the serial port of your
PC and Poseidon (Port 2)
•
Plug the power adaptor and
connect it to the Poseidon’s
power connector
•
If the power supply is OK, the
green POWER indicator should
light up.
•
A bit later after turning on the
power supply the red MODE
indicator should start blinking
•
Run any serial terminal on your
PC. Advantageous is using the
Hercules Setup Utility and its
Serial tab.

device. The device will then present itself on a serial terminal and offer the menu.
Entering the TCP Setup mode
You can enter the Setup mode via TCP/IP using, for instance, the standard Telnet program,
HyperTerminal utility (connection to IP address and TCP port) or from the “TCP Client” tab in the
Hercules program.
• TCP Port (99) – The TCP port 99 is set by default but can be changed in the Setup.
User name and password – can only be set using the Internet browser in a Flash Setup in
the tab „General Setup“. These values are not preset by default.

if a temperature goes outside of the “non-alarming” range defined (by user) for that sensor, or, if
enabled, a digital input closes..
The Trap Address should be set to the IP address of the SNMP supervisory centre (SNMP Manager).

Activation of 1-Wire sensors
Pressing „1“ in RS-232 Setup will bring the following dialogue:
Enable 1-Wire temperature sensors? (yes/no)
If you press ”y“, the Poseidon performs the autodetection procedure on the 1-Wire bus and tells you
how many sensors were found. :
Searching ...
4 sensors found
While configuring the sensors in the Setup mode it is necessary to have all the 1-Wire sensors
you wish Poseidon to work with connected, because it’s the only way to initialise them. Their number
cannot be changed manually.
1-Wire sensors connected later must be once again activated this way in the Setup mode. The IP
address of the sensor is kept, the unknown 1-Wire sensor is ignored.
Note:
If you reconnect a sensor which was connected during the most recent sensor
configuration,, Poseidon will recognize and read it.
Activation of RS-232 sensors
Pressing “2” from the RS-232 Setup will bring the following dialogue:
Enable RS232 temperature sensors? (yes/no) y)
Option is chosen by pressing ”y“ then Enter. The Poseidon then asks for number of sensors, and
awaits you answer, which should be 1 or 2:
Set how many available? (1..2)
: (0)
1
The sensor does not have to be connected to Poseidon at this time. If only one sensor is activated, it
is presumed to be connected to the port 2.
Activation of RS-485 sensors
For sensors connected over RS-485 their quantity must be defined, each sensor indentified with a
unique address on the RS-48R line. Autodetection can make this easier.
Pressing “3” from the RS-232 Setup will bring the following dialogue:
Enable RS485 temperature sensors? (yes/no)
Option is chosen by pressing „y“ or „n“ followed by Enter.

To change the address of one RS-485 sensor
If using RS-485 sensors where the address cannot be set using jumpers it’s sometimes necessary to
change the address assigned by production. This is only possible if there is just one sensor, whose
address can be changed, connected to RS-485 line at the time of the address change!
The Assign RS-485 sensor address function is chosen by pressing “9”:
Please check you have only one sensor on the RS-485 bus!

RS-485 sensor identification
Address of RS-485 sensors is taken into account of „ID“ variable, dumped in the XML interface and
the table on the WWW page. The address („0 .. 9“, „a .. z“ or „A .. Z“) corresponds to the decimal
value of the address character („0“=48, „1“=49, „A“=65, „a“=97, „z“=122).
Using this variable you can therefore uniquely identify which sensor is in which room until you assign them
human-friendly names using the Flash Set-up routine.

Special functions of RS-232 Setup - RS-232 / RS-485 converter
To make the advanced configuration of sensors on the RS-485 line easier, it’s possible to run a
simple RS-232 (Port 2) / RS-485 (Port 1) converter by this option. Warning: This can only be used
in the RS-232 Setup mode!
The RS232/485 mode of the converter is ideal for setting the address of the sensor on the RS-485
bus or for its more sophisticated configuration. An advantage is that you will not need any special
cable because the sensors are driven by the Poseidon as in regular operation.
u ... USART2 mode
[normal]
Pressing the ”u“ key in the RS-232 Setup mode will bring the following dialogue
UART2 mode (0..normal, 1..RS232/RS485 converter) : (0)
How to use the RS232/RS485 converter mode
•
Set DIP1 = On, DIP2 = On, DIP3=Off, DIP4=Off,
•
Connect the RS-232 cable to the Port 2
•
Connect the device to a RS-485 bus
•
Turn on Poseidon’s power supply
•
In RS-232 Setup mode set the RS232/RS485 converter mode, using the “u 1” option
•
Enter “x” to close the RS-232 Setup
Now your terminal works on the RS-485 line
•
To end the mode interrupt Poseidon’s power supply for 5 seconds
•
The RS-232 Setup menu runs again in the terminal
•
Using „u 0“ option switch to the normal mode
•
Enter “x” to close the RS-232 Setup mode, or set DIP1=Off and restart the device
Note:
More detailed information on setting the individual sensors can be found in the
manuals of the corresponding sensor.
Setting the addresses of sensors on RS-485
If using sensors on RS-485, which don’t allow setting the
address using jumpers, you can set the sensor’s address
using the ”UART2 converter mode“. In this mode you can
set the sensor address using the “T#x” command, where
”x“ specifies the new address for the sensor.
On the RS-485 only one sensor may be connected at the
time. If using the line for sending a macro command from
Hercules Setup program, the “#” character must be
doubled (A single # is used as a prefix to indicate
decimal values).
When assigning address “Z“, insert the sequence
”T##Z“ in the bottom line and SEND it. If the address
setting is OK, the sensor will confirm setting a new
address.

Warning:
The default values will even change the device’s IP address. The new values will be

Function is identical with interrupting Poseidon’s power supply. It’s necessary in case you have
changed the network configuration!
r ... system reboot
Closing the Setup mode - eXit
The function is identical with setting the DIP1 = OFF and restarting the device. The only difference is
that if the DIP1 is still ON, the red MODE indicator blinks and indicates the configuration in the RS232 Setup mode.
x ... exit
Note:
HW group
Try to avoid the following easy mistake: After you use the “x” command to leave the RS232 Setup mode, you must remember to set DIP1 back to ON. If you forget, then after
the power has been interrupted to reset the device, you will simply re-enter the Setup
mode... and, among other things, the sensors will stop working again.

User WWW interface
The Poseidon is equipped with a clear,
friendly graphic interface which displays
the measurements from the sensors. It
also allows complete administration and
setting the device, including the definition
of primary network parameters, measuring
sensors and error actions (SNMP traps).
The WWW interface is called by entering
Poseidon’s IP address into the address
line of a browser.
A webpage will appear showing the states
of the binary (digital) inputs and the values
measured by the sensors.
The page is automatically refreshed every
5 seconds.
Binary (Digital) Inputs
The page shows the state of the binary (digital) inputs. It also reports whether an alarm was sent or
not. and whether an alarm (SNMP trap) is defined for the corresponding input. If the input is causing
an alarm, the row background is made red. The input's state (Value) is represented by the symbols
O (Open) and X (Closed). O represents Open circuit, X Closed circuit (i.e. connected with the
Common pin).
Sensors
The “Sensors” table reports what sensors have been found, and what they were reading at the
moment when the page was loaded.
The data displayed:
•
Sensor name (Name) – The name of the sensor assigned by the user from Flash Setup.
•
Type of the connected interface (Type) – Sensor’s communication interface.
•
Identification code (ID) – Unique 16-bit identifier of the sensor’s address.
•
Measured value (Value) – Actual measured temperature. If the sensor is not connected,
None will appear here.
•
Range of the measured values (Alarm Range) – Range of the sensor’s values when alarm
is inactive.
•
Alarm (Out of Range) – Information whether any alarm is activated by any value exceeding
the defined range.
•
Row background colour: Red = Sensor in the alarm state, Yellow = sensor is out of range

Thermometer Sensors
Configuration of the temperature and humidity sensors’ behaviour:
•
Name – Human friendly sensor name(e. g. storage temperature, battery temperature, etc.).
•
Thermometer Type – Interface type where the relevant sensor is connected to (cannot be
changed).
•
Sensor ID – Unique identifier of the specific sensor within the Poseidon.
•
Temperature – Displays the current value returned by the sensor. If the sensor is not
connected, or malfunctioning, the value returned will be “None”.
•
Temp. Range – Adjustable range of values considered as correct. If the sensor returns a
value outside this range, it will be “alarming”, and, if enabled, an SNMP trap will be sent by the
Poseidon.
•
Hysteresis – Defines the insensitive range in case of exceeding the limit value. Prevents
setting off the multiple alarms when value oscillates around the limit value. See detailed
description below.
•
Alarm – Enables or disables the sending of SNMP traps.
Note:
All configuration changes must be confirmed by the Set Value button.
What is hysteresis
The value of Hysteresis defines the width of the tolerance zone for sending the alarm. The function
prevents setting off multiple alarms in case the value oscillates around the boundary defining the
“alarming” and “non-alarming” states. You can see the effect of the hysteresis setting from the graph
below. Notice in particular the line across the bottom of the graph which shows you when the device
was “alarming” and when it wasn't.
Without the 5°C hysteresis setting, the alarm would stop at point 1. It would also restart at point 2.
Etc. The hysteresis function ensuresthat the alarm was prolonged to the point where the temperature
reached the end of the hysteresis zone, for example at point 4 -15°C + 5°C = -10°C.

Problems you may encounter, and cures
•
Poseidon does not display the values of the sensors connected to RS-485:
Poseidon allows sensors to be powered directly from Port 1 for at most three temperature and
humidity sensors.. If there are too many sensors connected, you will need to provide an
external power supply.
•
The device is not available when you enter the IP address into a browser:
The device may be in the Setup mode. Check that DIP 1 is set to ON. The MODE LED should

Firmware Update over RS-232
Devices with old firmware, from the 1.6.2 version can be updated over the RS-232 interface.
Firmware is made up of a single file with the extension .HWg, which can be downloaded from our
WWW pages or we can send it via e-mail upon request.
Request: If you have any problems with upgrading your firmware please contact us.
Poseidon Firmware Upgrade – step by step
•
Turn the power supply off
•
Connect the Poseidon to the serial
port of your PC, using the RS-232
extension cable. Connect the cable
to Port 1 (DB9F on the device) of
the Poseidon device.
•
Set the switches DIP1=ON,
DIP2=OFF, DIP3=OFF, DIP4=OFF,
•
Run the Hercules Setup Utility and
go to the “Serial” tab.
•
Choose the serial port connecting
the PC to the Poseidon.
•
Click on the ”HWg FW update“ and
choose the appropriate file.
•
When the screen with the process
indicator appears, turn the
Poseidon's power supply on.
•
After the firmware has upload, the former parameters will be kept, Poseidon will restart and
should work correctly.
•
Don’t forget to set the jumpers DIP1 - DIP4 to the previous position. (Probably DIP1 - DIP4 =
OFF if not using RS-485, if using RS-485 then it would be DIP1,3,4=OFF, DIP2=ON)
Firmware upgrade via TCP
From version 1.8.0 of the firmware, updates can be
also uploaded via the http interface using the page
“/upload/“. However: during the file transfer a
connection dropout (etc.) must not occur. If this
upload is not successful, use the method described
above, using the RS-232 interface.

Using Poseidon with the provided third party software
We have found several good programs written by other people, and include them on the CD we
distribute with the Poseidon because we think they may be useful to you.
GetIf
Getif is an excellent utility for working with SNMP devices. It’s free, which entails some limitations,
but, on the other hand, it has many strengths.
•
Works directly with the MIB files; it’s not necessary to search for individual OIDs
•
Supports exploring trees; allows automatic downloading of whole structure of variables
•
Program is clear and compact
•
Allows easy and fast transfer of values to the graph, and graphing of them over time.
Getif has many bugs, e.g. it cannot be maximized to full screen, but we can recommend this program
for taking care of basic needs.
Installation and first steps of using the program Getif
•
Install the Getif program
•
Search for the installation directory and there for a subdirectory named /Mibs/ - save there
the MIB files of the devices you wish to work with. If the directory contains the “index” file,
delete it.
•
Run the Getif program and in the “Parameters” tab fill the “Host name” field with the IP
address of the device and press the “Start” button. Ignore the “No SNMP Response”
message. Sometimes you have to wait a little while for the LAN to initialise itself, so that the
PC can “see” the Poseidon.

HW group
•
Go to the “Mbrowser” tab and press the “Start” button. At the bottom of the window you will
receive the complete list of the variables available for the device over SNMP.
•
Notice that the penultimate line always contains the OID of the given variable (e.g.
„.1.3.6.1.4.1.17739.3.3.3.1.6.1“ for „poseidon.tempTable.tempEntry.tempValue“).Next to it is
the format of the variable (here it is integer) and then there is the value (here you would see
223 if the sensor was reading 22.3 °C).
In the program the variables can be set or their values changed simply by entering the new value
and pressing the “Set” button. Writing must be allowed in Poseidon from the given group and you
must write the allowed range of variables (see the type of variables, assigning the meaning to the
values of the state variables can be found in the upper right field “Enums”).

SNMP Trap Watcher
Very simple utility for displaying the received
SNMP Traps or their filtration. The utility cannot
analyse the information in terms of MIB table so it
has limited abilities but is sufficient for a basic
demonstration.
The program does not require installation, just run
it, set the IP address of your PC to Poseidon as a
receiver of SNMP Traps, use default port 162. In
the example shown here we have generated an
alarm by connecting the Binary 2 input whose
alarm was preset to “Alarm if Closed”.

SNMPView
SNMPView is a freeware SNMP client suitable for testing the functionality of the Poseidon. It is a
client with limited abilities (cannot work with MIB
tables, cannot receive SNMP Traps), but for
verification of basic SNMP functions is more
than sufficient.
Wider usage is limited by the fact that the
program can load only one variable on one
SNMP packet so it’s not suitable for watching
more sensors on one device.
Definitions and IP addresses of sensors that the program should read can be set in configuration
files. When using SNMPView edit files „devices.txt“ (set Poseidon’s IP address) and
„snmpview.cfg“ and configure the list of the read variables from the line „#OID-Tabelle 0„.
Program and configuration files can be found in the pack of utilities on the supplied CD.

Address configuration of sensors on the 1-Wire bus
All sensors at 1-Wire bus have a unique identifier, on sensor change, addition or removing the sensor
from the system it’s necessary to run again the autodetection of the 1-Wire sensors from the TCP
Setup or RS-232 Setup. The address of the sensor (or the last 2 bytes from 6 identifier bytes) is
displayed as “ID” sensor.
Address configuration of sensors on the RS-485 bus
All sensors on the RS-485 bus are identified by assigned address. When changing the sensor it’s
fully sufficient to replace the sensor with other sensor with the same RS-485 address.
To add or remove the sensor from the system it’s necessary to run the autodetection of RS-485
sensors from the menu in TCP Setup or RS-232 Setup. The address of the sensor („0 .. 9“, „a .. z“ or
„A .. Z“) is displayed in the item of “ID” sensor. The number in the “ID” corresponds to the decimal
value of the address character („0“=48, „1“=49, „A“=65, „a“=97, „z“=122).
Some sensors allow setting the address of the sensor using a jumper on the sensor. Other sensors
do not have the configuration jumpers and the default value is stated on the sensor’s plate. If
you connect only one such sensor to RS-485 bus, you can assign another address to it in the
TCP Setup or RS-232 Setup menu.

Thermometers using the Pt100 temperature sensors
Temp-485-Pt100 and Temp-485-2xPt100 are thermometers communicating over
RS-485. They use external platinum sensor Pt100 (or Pt1000). These
thermometers are supplied in the following versions:
• Temp-485-Pt100 „Box“ version
Complete boxed temperature sensor intended for wall mounting. Contains
the RS-485 / thermal sensor (Head version) converter and the Pt100/B
sensor itself lead out from the plastic IP65 box.
•
Temp-485-Pt100 „Head“ version
The „Head“ version is a unit of the converter of the temperature measured
by the external thermal sensor to the data RS-485 bus. The mechanic
version of the converter is intended for mounting into a uniform “B”
thermometer head. To create the thermometer it’s necessary to connect
external Pt100 temperature sensor – platinum linear sensor (not part of
the shipment), which is connected by two or three conductors.
•
Temp-485-Pt100 „Cable“ version
A thermometer made up of a box intended for wall mounting and the RS485 / thermal sensor (Head version) converter. The Pt100/A sensor itself is connected
on the 2 meters long cable, which is part of the shipment.
•
Temp-485-Pt100 „DIN“ version
The “DIN“ assembly is for connecting an external thermal sensor to the RS485 bus. The assembly fits a standard DIN mounting. In addition to the
assembly, you will need an external Pt100 temperature sensor – platinum
linear sensor, which is not included with the assembly. The sensor is
connected by two or three wires.
•
Temp-485-2xPt100 „DIN“ version
The converter measuring the temperature of two external Pt100
thermometers and sending the results to the RS-485 data bus. The
mechanic version of the converter is intended for mounting to a standard
DIN molding. To create the thermometer it’s necessary to connect two
external Pt100 sensors (are not the part of the shipment), which are
connected by two or three conductors.
•
Pt100 – PT30 type
This is a resistance Pt100 temperature sensor intended for use with the
assemblies listed above. The sensor is inside a metal rod and connected by
a 2 meter, 4-conductor cable. The sensor is usually fastened down to
whatever is being monitored with a metal strap..
