17.3.MODBUS Termination
Blocks
Because the XEV22D device has no on-board
means of termination, use the MODBUS termination
block (P/N 535-2711) for termination that can be
wired to the end of the cable segment using the three-
pin connector. Wire the two signal wires to the out-
side terminals, and connect the shield to pin 16, keep-
ing the exposed shield wire length as short as possible
(3 inches ideal maximum length).
