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.

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. Hardware Interface
The main features of the CIM are described as follows with reference to the following

Notes:
1) See user manual for available Port 2 & 3 protocols.
2) The internal modem is disabled when a local Port 2 connection is made.
3) Port 3B is MEC 20 and TSC 800 pin compatible.

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.
