COMMUNICATION INTERFACE MODULE (CIM)
VERSION 3.0
1. Introduction
This section is intended version 3.0 of the Communication Interface Module (CIM). For
other product versions, contact Thomson Technology, Inc. to obtain applicable
instruction manuals.
The Thomson Technology (TTI) remote communication system with the CIM 3.0 and
Modbus™ protocol provides remote monitoring and control of TTI microprocessor-based
controllers as used in the power generation industry. The system consists of 2 main
components as follows:
• Communication Interface Module (CIM): The CIM provides the hardware and
software interface between a Modbus compliant device (customer supplied) and the
specific microprocessor-based controllers as used at a generator site.
• Remote Terminal Unit (RTU): An RTU is a device that directly operates the
equipment at a generator site. These devices are the actual microprocessor-based
controllers as developed by Thomson Technology, Inc. (e.g. MEC 20 engine
controller or TSC 800 transfer switch controller.
The following diagram depicts a typical remote communication system.

Some advanced features of the remote communication system with the CIM 3.0 module
and Modbus™ protocol are as follows:
• One CIM module can control and monitor up to 10 RTUs at a generator site using a
single direct serial/phone link.
• Configuration of all communication system setpoints is done using software.
• CIM Port #2 can be configured for RS-232, RS-422 or RS-485 serial communication
types. RS-485 communication allows multiple CIM's to be interconnected to any
Modbus™ RS-485 network. RS-485 is recommended for the best distance and noise
immunity. Port #2 has a hardware protocol auto-detection option that removes the
confusion of determining whether the port is in RS-232 or RS-485 mode. Just plug in
and communicate (assuming the baud rate etc. is set correctly).
• Security features have been implemented to allow password protection. However
these features along with auto-detection and modem functionality can be bypassed
with a "fixed Modbus" option that is intended for direct PLC function where remote
access is not necessary.
• With onboard modem support, CIM 3.0 offers remote telephone connectivity with
auto callout and pager support with up to 32 characters. Up to 3 phone numbers can
be programmed into the CIM for remote THS connection or pager notification. In the
case of a failed connection, retries can be specified.
Further information on the Modbus™ protocol support on the CIM can be found in
SECTION 3 and at the Modicon website (www.modicon.com).
NOTE: Throughout this document, CIM's, MEC 20's and TSC 800's are generically
referred to as remotes.
2. General Description
The Communication Interface Module (CIM) is an advanced communication interface
device for remote communication to Thomson Technology's latest generation of
Microprocessor-based engine generator and transfer switch control products. One CIM
module can communicate with networked MEC 20 engine generator controllers or TSC
800 transfer controllers. The serial communication ports can be used for direct
connection to a personal computer (port #2) or to other remote connected devices (port
#3). An internal modem is available with the CIM, which provides direct connection to a
telephone system.

SECTION 1 COMMUNICATION INTERFACE MODULE
PM055 Rev 2 00/08/31 Thomson Technology

The CIM provides the following advanced features:
• Dedicated Microprocessor-based design provides fast operation without restricting
RTU operation.
• One CIM module can provide interface to a complete networked RTU system. This
leads to a single telephone line connection per site rather than typical multiple line
solutions.
• Internal 14.4 kbaud modem available for direct connection to telephone system.
• Flexible design provides two fully configurable serial ports.
• Standard plug-in telephone RJ45/RJ11 type jacks and DB9 computer ports provide
simple interconnection to system.
• The ability to callout to a THS host station or pager when an RTU fault occurs frees
the user from continual monitoring. It also allows for immediate remote response to
problems.

3.1. DC Power Input: Terminals are provided for DC power input to the CIM
module. Power input is non-polarity sensitive and can range from 8-
35Vdc.
3.2. Telephone Port: The telephone port is used to interconnect to a telephone
system. This port is internally connected to a 14.4 Kbaud modem. This
port uses a 6 pin RJ11 plug-in jack connection.
3.3. Diagnostic LEDs: The CIM module provides four diagnostics LED lights
are described as follows:
• Power: This LED is illuminated whenever the CIM has correct DC
supply voltage applied.
• Service: This LED illuminates when the CIM has an internal fault in
which the unit must require service.
• DC Fault: This LED is illuminated whenever the CIM's internal power
supply has shutdown do an internal fault or an external overvoltage
condition from the DC supply input. To reset a DC fault, the DC supply
voltage must be removed for 30 seconds, then re-applied.
3.4. Internal Modem: The CIM is provided with an internal 14.4 Kbaud
modem. The modem is internally connected between the telephone port
and port 2A/B.
3.5. Port 2B: Port 2B may be interconnected to a remote terminal unit (RTU)
or Personal computer (PC). Port 2B can be configured to RS-232 or RS-
485/-422 type transmission signal. When a personal computer is
connected to Port 2B, a null modem cable or connector must be used.
When the CIM modules' internal modem is used, port 2B is disabled. This
port uses an 8 pin RJ45 plug-in connector. An LED indicator is provided
to signal when the port is communicating. Port 2B is internally wired in
parallel with Port 2A.
3.6. Port 2A: Port 2A may be interconnected to a remote terminal unit (RTU)
or PC. Port 2A can be configured to RS-232 or RS-485/-422 type
transmission signal. When a personal computer is connected to Port 2A,
a null modem cable or connector must be used in series with the PC
cable. When the CIM modules' internal modem is used, port 2A is
disabled. This port uses a 9 pin standard DB9 female plug-in connector.

An LED indicator is provided to signal when the port is Transmitting. Port
2A is internally wired in parallel with Port 2B.
3.7. Port 3B: This port may be interconnected to a remote terminal unit (RTU).
Port 3B utilizes a RS-422 type transmission signal that is compatible with
MEC 20 or TSC 800 controllers. The standard connection for a MEC 20
or TSC 800 controller (RTU) application is for port 3B to be connected to
the RTU. This port uses an 8 pin RJ45 plug-in connector and allows for a
direct connection to TTI MEC 20 and/or TSC 800 controllers. Port 3B is
internally wired in parallel with Port 3A.
3.8. Port 3A. This port may be interconnected to a remote terminal unit (RTU)
or directly to a PC. Port 3A utilizes a RS-422 type transmission signal that
is compatible with MEC 20 or TSC 800 controllers. The standard
connection for a MEC 20 or TSC 800 controller (RTU) application is for
port 3A to be connected to the RTU. This port uses a 9 pin DB9 female
connector. Port 3A is internally wired in parallel with Port 3B.
NOTE: CIM Port 2 cannot be used concurrently with the modem (CIM Port 1). An RS-
232 or RS-422 cable can be connected to the CIM, but cannot be active if the modem is
to be used. An RS-485 connection will effectively disable the modem whether it is active
or inactive.

7. CIM Operation Functions
The CIM module provides the following main functions when used in a communication
system:
RTU & Modbus™ Device Interface: The CIM is the main communication interface
component between a Modbus™ compliant device and the remote terminal units. The
CIM provides the necessary hardware interface (i.e. COM Ports) as well as the
Modbus™ software protocol interface.
Protocol Data Processing: The CIM receives incoming communication signals from
various types of RTUs and processes the data into the specific Modbus™ language as
required for the application. The processed data then gets transferred to the applicable
port and transmitted to a remote Modbus™ compliant device.
CIM Configuration: The CIM stores vital information in non-volatile FLASH memory
pertaining to a specific RTU site as defined by the user. Stored information includes, site
name, site passwords, and auto callout phone numbers (3).
RTU Polling: The CIM module will automatically poll connected RTUs to determine their
operating status and to signal an auto callout (callout is only operational when the
modem feature is operational) to the remote Modbus™ compliant device to alert a user
of an abnormal condition.

10. CIM Installation
NOTE: Installations should be done according to all applicable electrical regulation
codes as required.
The following installation guidelines are provided for general information only pertaining
to typical site installations. For specific site installation information, consult Thomson
Technology as required.
CAUTION!!! Qualified personnel must do all installation and/or service work
performed only. Failure to do so may cause personal injury or death.
10.1. Battery Supply Input
The CIM can operate on any battery supply from 8 to 35 volts DC nominal
Wiring from the system battery to the CIM should conform to the following
guidelines to avoid possible communication module malfunction and/or
damage.
Avoid wiring from the engine starter terminals - wiring should go directly
from the battery terminals to the control panel where the CIM module is
located (to avoid voltage drop in the starter cables and starter motor
commutation noise).
CAUTION!!! The battery charger must be turned off before battery cables
are removed from the battery (i.e. for servicing). Failure to do so may
subject the control panel to an overvoltage condition in which damage
may result.
Under noisy environments (i.e. gas engines with high voltage ignitions,
etc.), wiring from battery should be a twisted pair of #14 AWG (2.5mm2)
wires.
The use of AC or DC operated solenoids or relays in control systems can
sometimes cause high voltage spikes on the DC power supply, which
may cause electronic devices to fail. Transient suppression devices are
recommended for all inductive devices sharing wiring or if physically
located near the CIM module. For DC operated relays or solenoids, use a
suitably rated counter EMF Diode (or commonly known as "freewheeling"
diode). For AC operated relays or solenoids, use a suitably rated metal
oxide varistor (MOV) or capacitor/resistor suppressor.

SECTION 1 COMMUNICATION INTERFACE MODULE
PM055 Rev 2 00/08/31 Thomson Technology
10
10.2. Remote Communication Wiring
All communication interconnecting wiring to/from the CIM Module shall
utilize #22 AWG-8 wire, twisted, shielded cable with RJ45 connectors.
All remote communication wiring outside the control panel must be run in
separate conduit and shall not be located near AC power cables to
prevent pick-up of induced voltages.
10.3. Dielectric Testing
Do not perform any high voltage dielectric testing on the CIM connected
in the circuit as serious damage will occur to the module.
10.4. Mounting Location/Installation
The CIM Module is designed for mounting directly onto a control panel
inner sub-panel. Considerations should be given for the following:
The controller should be installed in a dirt free, dry location away from
extreme heat sources. Adequate space should be provided around the
CIM module for control wiring.

10.6.2. RS-485/-422 Connection
The following hardware configuration is required for 4 wire RS-
485/-422 from the port 2 on the CIM to an RS-232 port on a
computer:
The following parts are connected in order from the RS-232 side
(computer) to the RS-485/-422 side (the CIM).
RS-232 to RS-485 or RS-422 adapter (set to DCE)
DB-25 to RJ45 adapter (or custom cable) for RS-422/-485 on the
CIM port 2(see below wiring).
Insure that the correct handshaking signals are connected on the
RS-232 side of the RS-485/-422 converter. Many RS-485
converters use the RTS line to control the transmitter (which must
be tri-stated during receive mode). It is important to insure that the
converter is configured correctly and the correct handshaking lines
are wiring appropriately. If the handshaking lines (RTS) are not
wired correctly the connection may appear to work but damage
may occur and communications may be unreliable over time.

• Note that the RS-232 side of the RS-485 converter will most
likely require the RTS line be connected along with TX, RX
and GND.
11. Troubleshooting
Refer to the following list of typical problems. Consult the factory for any detailed
information or for any problems not listed.
CAUTION!!! Before opening the enclosure to perform any service task, it is
imperative to isolate the control system from any possible source of power.
Failure to do so may result in serious personal injury or death due to electrical
shock.
Service procedures must be undertaken by qualified personnel only!
SYMPTOM CORRECTIVE ACTION
CIM does not
power up even
with correct DC
power applied
Check that there are no wiring errors/short circuits connected to
the CIM. Note: The CIM Module contains an electronic fuse that
triggers upon an overload or overvoltage condition and does not
reset until the supply voltage is removed.
Failure to
communicate with
PC (direct
connected).
Verify all communication cables are connected to the correct
ports.
Ensure that the RTU's (TSC 800 and MEC 20) are connected to
Port 3 on the CIM.
Ensure the correct MEC 20 communication port (J7) is utilized.

20 is for the expansion port, damage may occur to the CIM if this
port is connected! When direct connection is used from port 2A
to a PC, ensure a null modem cable or connector is used. (see
Host PC Connection).
Verify all settings in the THS 2000 program are correct. Critical
settings are as follows:
Port 3 baud rate--4800
Controller address--THS setting and controller setting must
match
Site Name--THS setting and CIM setting must match. Note:
factory default setting in CIM is "site"
Site Password--THS setting and CIM setting must match. Note:
factory defeat setting in CIM is "user".
If multiple MEC 20 controllers are connected to a single system,
verify all controller node addresses are different.
RTU site may be busy calling out if an alarm condition is present
on the controller. Reset all fault conditions at the controller and
set for automatic mode to cancel the auto call out condition.

Verify PC modem operates correctly (test independently with
another software system).
Verify PC modem is set for 9600 baud operation.
Ensure phone numbers programmed for both PC site location
and RTU equipment location are correct.

If you encounter difficulty connecting to a CIM with the Host
software make sure the CIM is not trying to call-out. When the
CIM is trying to call-out to the Host sites it will not respond to
outside requests for connection. In this situation the user can be
patient and make repeated attempts at connection until the CIM
has exhausted its phone numbers and retries (can be over 12
mins in some cases with 3 numbers and 3 retries). Or the user
can let the host successfully call-out to the Host software. After
the phone numbers are successfully attempted or retries are
exhausted the CIM will go back into a log-in ready state. If time is
important, the CIM may be power cycled, for a brief time after the
CIM power is restored (after the 2 quick blinks on the Port 2
LED) the CIM will be log-in ready. However the CIM will
eventually go into a call-out state to report the site alarm
situation.
The above situation is the most common cause for not bein
