Introduction
1.1 What is CYMOD?
CYMOD is a series of data acquisition modules. It provides a total solution of
the data acquisition network and control system. You can remotely control up to
256 CYMOD modules on RS-485 netowrk. All you need is to use a host
computer, like a liPC (Personal Computer), with one RS-232 serial port for
controlling the whole system. The maximum communication distance is 4000
feet from the host computer.
CYMOD is based on the RS-485 multi -drop network system, each module has
an unique address ID. Using simple ASCII command & response protocol
through standard RS-485 interface can control all the CYMOD modules in the
RS-485 network.
The CYMOD modules provide direct linkage to a wide variety of sensors and
perform all signal conditioning, scaling, linearization and conversion. The
modules can be used to measure temperature, pressure, flow, voltage, current
and numerous types of digital signals.
Introduction • 1
1.2 Outstanding Features of CYMOD
l
Industry standard networking
All CYMOD modules use the RS-485 communication protocol for transmitting
and receiving at high rates and over long distance.
l
Two-wire and multi-drop communication
A single twisted pair of wires is used to transmit and receive data between
modules. Multi-drop capability makes system configuration more flexible and
makes it easy to set up a network.
l
High transfer speed
CYMOD modules provide up to 115.2K bps data / command transfer rate, which
can promote system bandwidth.
l
Simple command / response protocol
All communications are performed with printable ASCII characters. This
allows the information to be processed with string functions common to the
most high-level languages.
l
Industrial design
The screw terminal plug connectors on every CYMOD module ensure simple
installation and easy modification. The compact size allows the modules to be
mounted on DIN rail, back-panel wall-mount, etc.
l
Watch-dog supervisory
CYMOD contains a watch-dog supervisory circuitry that will automatically reset
the module when the system fails. In addition, a user-programmable s oftware
timer provides a "safe" output signal in the event of host computer failure.
l
High isolation voltage
CYMOD provides photo -isolators, which ensure high isolation voltage
between the data acquisition circuits and the communication port. The fatal
electric-shock won‘t go through and damage all the modules on the network.
l
Noise immunity
The CYMOD provide extra noise immunity capability. An electrode, which is
coated inside the ABS case, can reduce electro-magnetic interference (EMI)
and noise.
2 • Introduction
l
Harsh environmental protection
A surface coating covers on the PCB and electronic components of the CYMOD.
It allows superior resistance to harsh environment such as humidity, salt spray
and most harsh chemicals.

1.4 EIA RS-485 Standard
The EIA RS-485 interface is a communication standard developed for
multi-dropped systems that can communicate at high rate over long distance.
The standard RS-485 can operate at speed up to 10 M bps over cable length up
to 4000 feet.
The RS-485 interface can support up to 32 drivers/receivers on the same line.
This allows actual networking applications on a parity line system (sometimes
called multi -drop).
The RS-485 uses differential transmission on a balance line. Its easy wiring
make it popular to use in industrial applications .
1.5 RS-485 on CYMOD
The CYMOD improves the RS-485 capability for minimizing the user's cost. On
each CYMOD module, a half-duplex RS-485 transceiver is used to
communicate with other modules. A single twisted pair of wires, which
provides standard differential transmission, is used to transmit and receive
data between modules. The high input impedance of each CYMOD receiver
allows up to 128 CYMOD modules on the same RS-485 bus without using a
signal repeater.
The maximum transfer rate of CYMOD is 115.2 Kbps which is lower than the
maximum speed of the RS-485 standard. The slew-rate limiter on every
RS-485 transceiver of CYMOD is very useful for transmitting error-free data,
minimizing EMI, and reducing reflections caused by improperly terminated
cables.
The CYMOD on a network may not use the same power supply. Therefore, the
voltage difference between ground of the modules may exist.
Excessive output current and power dissipation caused by faults or by bus
contention are prevented by the current limiter and the thermal shutdown
circuitry inside the CYMOD.
4 • Introduction
1.6 CYMOD RS-485 Network Configurations
CYMOD 400 Series is designed under RS-485 multi -drop network
architecture. Up to 256 CYMOD modules can be controlled in a multi -drop
network. The limit of 256 is due to command code. The network can be
connected by simple topology (Figure 1-1) or branch topology (Figure 1-2) or
free topology (Figure 1-3).
The CM 4520 and CM 4510 are the two basic communication modules to
construct a RS-485 network. The CM 4520 is a RS-232 to RS-485/RS-422
converter. The CM 4520 is used to build a RS-485 port for the host computer by
converting standard RS-232 signal into RS-485 signal.
The CM 4510 is the RS-485 signal repeater which is used to extend or to
lengthen the network distance. A CYMOD bus can connect up to 256 modules,
each segment is up to 128 modules. Whenever the numbers of the modules
excess 128, the repeater should be used. In addition, the length of a standard
RS-485 bus is up to 4000 feet, the repeater should be used whenever the
length of a signal bus is more than 4000 feet.
The CM 4530 is the USB to RS-485/RS-422/RS-232 converter, and it used to
build the USB signal into RS-485/RS-422/RS-232 signal.
The CM 4524 is an addressable RS-485/RS-422 to RS-232 converter, it allows
the RS-232 devices to easily link to the Host by the RS-485/422 bus.

1.7 Constructing a CYMOD Network
1. Set up a CM 4520 or CM 4530.
2. Connect the host computer with the CM 4520 or CM 4530.
3. Set up one or more CM 4510 if necessary.
4. Connect the CM 4510 to extend to RS-485 bus if necessary.
5. Install the CYMOD utility software or CM 4530 driver from disk.
6. Initialize the brand-new CYMOD modules.
7. Add the new CYMOD modules into RS-485 network.
Refer to chapter 2 and chapter 4 for executing step 1 and 2. Refer to chapter 3
for executing step 3. Chapter 4 explains the best time to install CM 4510. The
information about the software for operating the CYMOD is in chapter 6. For
executing step 6 and step 7, please refer to the install procedures of each
module along with chapter 6, "Software Utility."
1.8 Termination Bus
In order to avoid signal reflections on the bus, each bus segment has to be
blanked off at its physical beginning and at its end with the characteristic
impedance. A termination resister ( Rt) is intalled for this purpose. The Rt
value - 120Ω ± 2% is recommended, and the detailed connection of Rt can be
referred from the “Terminator Connection” diagram below.

1.9. Shielding
In case of increased interference, shielded bus cables are recommended
for both intra and inter-module wiring . In addition, shielding should
also be employed for power supply and signal cables.
Shielding Recommendations:
1. The shield should be connected with protective grounding at each bus
connection.
2. The shield should be applied several times along the course of
the cable.
3. The shield should be applied directly to the computer, or to separate shield
rails.

CYMOD 4520
2.1. Overview
What is CYMOD 6520 ?
CYMOD 4520 is a RS-232 to RS-422/RS-485 converter, it converts the RS-232
signal to the RS-422/RS-485 signals. The CM 4520 can be considered an
extension RS-422/RS-485 serial port for the host computer. A standard 9-pin
D-type connector is used to connect the host computer and the CM 4520.
Hence, the CM 4520 can connect with all kinds of PCs, IPCs or Notebook PCs,
which employ a standard RS-232 interface.

2.2 Setup
Objective of Setup
Normally, it is not necessary to setup the CYMOD 4520. The default
configuration of this communication module is 9600 bps, and data format of 8
data bits with 1 start bit, 1 stop bit, and no parity check. Note that the data format
is reserved to be compatible with other brand's communication port; it should
not be modified if only CYMODs are used in a system. The baud rate can be
configured according to the application's requirement.
Setup Equipment
A screw driver is necessary to open the case. Software, power supply, and wiring
require no additional installation equipment.
Setup Procedure
Only the hardware switch setting can be setup in CM 4520. The user can set the
speed of the serial interface ( RS-232 and RS-422/RS-485 ), and the serial
data format. The speed and the data format on the entire RS-485 network must
be identical.
To setup the CM 4520, use the screw driver to open the case, then change the
switch setting. The new setting is available after power up. The cover must be
re-installed and locked carefully. Do not scratch the surface of the circuit while
setting it up, otherwise the surface coating or the circuits themselves can
be damaged.
(Note: For Harware Rev.C1 or later, there is switchless baud rate
adjustment; the baud rate, parity and data bits adjust automatically.)

3.2. Setup
Objective of Setup
Normally, the CYMOD 4510 only needs to be set up when the CYMOD
bus exceeds 128 modules, or the bus distance exceeds 4000 feet. The
default configuration of this communication module is 9600 bps and data
format of 8 data bits with 1 start bit, 1 stop bit, and no parity check. Note that the
data format is reserved to be compatible with other brand's communication
ports, it should not be modified if only the CYMOD brand is used in a system.
The baud rate can be configured according user’s requirement.
Setup Equipment
Only screw driver is used to open the case. Software, power supply, and wiring
do not require additional installation equipment.
Setup Procedure
Only the hardware switch setting can be setup in CM 4510. The user can set the
speed and the data format of the RS-422/RS-485 interface. The speed and the
data format on the entire network must be identical.
To set up the CM 4510, use the screw driver to open the case, then change the
switch setting. The new setting is available after power up. The case must be
re-installed and locked carefully. Do not scratch the surface of the circuit while
setting it up; the surface coating or even the circuits may be damaged as a
result.
(Note: For Harware Rev.C1 or later, there is switchless baud rate
adjustment; the baud rate, parity, and data bits adjust automatically.)

5.2 Initialization & Installation
Software Installation
1. If CYMOD Administration is installed, skip the subsequent steps.
2. Backup your software diskette.
3. Insert the Administration disc into CD-ROM.
4. Change the drive path of CD-ROM to reflect your CD-ROMs assigned drive letter.
5. Find the setup of CYMOD Administration and run it.
6. Please follow the steps of setup program to succesfully install the Administration
software.
Objective of Initializing a Brand-New CYMOD 4531
All CYMOD modules except CYMOD 4520, 4510, and 4530, in a RS-485
network must have an unique address ID, however, every brand-new
CYMOD 4531 has a factory default setting as following:
♦
♦
♦
♦
Address ID is 0 1.
Baud rate is 9600 bps
RS-485 Interface
Host Watchdog timer is disable
Therefore, you must configure a new CYMOD unit before use,
otherwise the default address ID will conflict with other modules. The b aud
rate may also be changed according to user‘s requirements.
Default State
The CYMOD I/O modules must be set at Default State when you want to change
the default settings, such as the ID address, baud rate, check-sum status etc.
All CYMOD I/O modules have a special pin labeled as DEFAULT*. The module
will be in Default State if the DEFAULT* pin is shorted to ground when the power
is ON. In this state, the default configuration is set as following:
♦
♦
♦
Address ID is 00.
Baud rate is 9600 bps.
RS-485 Interface
CYMOD 4531 • 51
Therefore, the communication between host and the module can easily be
set with the same configuration, making the initialization of a module possible no
matter what configuration is set.

5.4.1 Command and Response
Introduction
The CYMOD command is composed by numbers of characteristics, including
the leading code, address ID, the variables and a carriage return to indicate the
end of a command. The host computer can command only one CYMOD
module. The slave device may or may not give response to the command.

Leading Code is the first character of the CYMOD
command. All CYMOD commands need a command
leading code, such as %,$,#,@,...etc.
1- character
Module’s address ID, the value is in the range of 00 - FF
(Hexadecimal) if no specified in the following.
2- character
Items indicate command codes or value of variables.
Variable length
Some output commands need data.
Variable length
Checksum in brackets indicates an optional parameter.
This field is required only if checksum is enabled.
2- character
Identifies a control code character, such as <CR> for
carriage return, its value is 0x0D. 1- character

Response of CYMOD Commands
The response message depends on CYMOD command. The response is also
composed with several characteristics, including leading code, variables, and
carriage return for ending. There are two kinds of leading code for response
message: ”!“ or ”>“ means valid command, and ”?“ means invalid. By checking
the response messages, a user can monitor device status.
Note : Under the following conditions, there will be no response
message.
1. The specified address ID does not exist.
2. Syntax error.
3. Communication error.
4. Some special commands do not have response.

Product Service
Diagnosis and Debug
CyberResearch, Inc. maintains technical support lines staffed by experienced
Applications Engineers and Technicians. There is no charge to call and we will
return your call promptly if it is received while our lines are busy. Most problems
encountered with data acquisition products can be solved over the phone. Signal
connections and programming are the two most common sources of difficulty.
CyberResearch support personnel can help you solve these problems, especially if
you are prepared for the call.
To ensure your call’s overall success and expediency:
1) Have the phone close to the PC so you can conveniently and quickly take action
that the Applications Engineer might suggest.
2) Be prepared to open your PC, remove boards, report back-switch or jumper
settings, and possibly change settings before reinstalling the modules.
3) Have a volt meter handy to take measurements of the signals you are trying to
measure as well as the signals on the board, module, or power supply.
4) Isolate problem areas that are not working as you expected.
5) Have the source code to the program you are having trouble with available so
that preceding and prerequisite modes can be referenced and discussed.
6) Have the manual at hand. Also have the product’s utility disks and any other
relevant disks nearby so programs and version numbers can be checked.
Preparation will facilitate the diagnosis procedure, save you time, and avoid repeated
calls. Here are a few preliminary actions you can take before you call which may
solve some of the more common problems:
1) Check the PC-bus power and any power supply signals.
2) Check the voltage level of the signal between SIGNAL HIGH and SIGNAL LOW,
or SIGNAL+ and SIGNAL– . It CANNOT exceed the full scale range of the board.
3) Check the other boards in your PC or modules on the network for address and
interrupt conflicts.
4) Refer to the example programs as a baseline for comparing code.
