C32020T Link Cable

There are two different types of link cables: 25-signal-pin link cable and 10-signal- pin link cable. The

former is used when there is no external power applied to the external module (CPU/Basic Module). The latter

is used when the external power is applied to the external module (CPU/Basic Module) if you have chosen to

use Long Rang Extension Kit.

25-signal-pin Link Cable (standard)

The factory-supplied 2-meter link cable (the one with 25 signal pins) is used only when you are NOT using the

external power adapter. Pin assignments are given below for this 25-pin link cable.

WARNING

Do not use the factory

-supplied 2-

meter link cable (with 25 signal pins) and the external power adapter at the

same time, otherwise the Control Board or CPU/Basic Module may be seriously damaged.
