ALSO IT IS RECOMMENDED TO MAKE ANY NECESSARY CONNECTIONS
INSIDE THE CABLE CONNECTOR TO BE MOUNTED ON THE PLC. IT IS
NOT RECOMMENDED TO USE TERMINAL STRIPS TO OTHER TYPES OF
CONNECTORS ALONG THE LENGTH OF THE TRANSMISSION LINE.
* TERMINATION RESISTANCE FOR THE RECEIVE DATA (RD) SIGNAL NEEDS TO BE CONNECTED ONLY ON UNITS AT THE END OF THE LINES. THIS TERMINATION IS MADE ON THE
SERIES 90 PLC PRODUCTS BY CONNECTING A JUMPER BETWEEN PIN 9 AND PIN 10 INSIDE THE 15-PIN D-SHELL WITH THE FOLLOWING EXCEPTION. FOR SERIES 90-70 PLCs,
CATALOG NUMBERS IC697CPU731 AND IC697CPU771, THE TERMINATION FOR RD AT THE PLC IS IMPLEMENTED BY A JUMPER BETWEEN PIN 9 AND PIN 11.
GROUND POTENTIAL: MULTIPLE UNITS, NOT CONNECTED TO THE SAME POWER SOURCE, MUST HAVE COMMON GROUND POTENTIALS OR GROUND ISOLATION FOR PROPER
OPERATION OF THIS SYSTEM.
