A Termination Resistance Unit (CV500-TER01) must be attached to all unused
I/O connectors of I/O Control and I/O Interface Units in the system. Failure to
attach Termination Resistance Units to the unused I/O connectors will result in
an error and the incorrect operation of the PC. The following example illustrates
the locations where Termination Resistance Units are required. Two Termina-
tion Resistance Units are provided with the CV500-IC101/201 I/O Control Unit.
