3.2.4. COMMUNICATION PORT
A communication port is provided to interconnect to a remote communication system
for remote monitoring and control of the transfer switch. Refer to Section 4 for
additional information.
3.2.5. CONTRAST ADJUSTMENT
A contrast adjustment potentiometer is located on the PCB and is factory set for
ambient temperatures of 15° to 30° Celsius. For different ambient temperatures,
consult the factory for adjustment procedures.
4. REMOTE COMMUNICATION
The TSC 800 transfer switch controller is available with a remote communication feature. The remote
communication feature allows a TSC 800 controller to be monitored and controlled from a remote
location via serial communication link to a personal computer (PC). PC’s may be connected locally
via serial communication cable to the TSC 800 or remotely via modem and telephone systems.
Remote communication can be via customer-supplied equipment or with an external communication
interface module (CIM) as manufactured by Thomson Technology.
NOTE:
The CIM module may be located in the engine control panel
provided the maximum distance between the CIM and TSC 800
controller is not exceeded as per the following information.
Refer to the installation section of this manual for further
information.
The CIM module utilizes an internal modem and contains Modbus
TM
protocol to interface with different
remote monitoring software programs. Refer to separate literature for detailed information on the
CIM module.
The TSC 800 communication port utilizes a RS422 data transmission signal that is directly
interconnected to the CIM module via an 8 conductor, shielded cable with plug-in RJ45 connectors.
Refer to FIGURES 9 & 10 for detailed information on direct connected or remote connected PC
applications with CIM module.

Trademarks belong to their respective parties.
NOTE: Both phone and serial communications ports cannot be connected at the same time. Doing
so will result in no communication and/or possible CIM failure.
