Jumpers

There are two jumpers associated with each digital input channel for
configuring the channel as either isolated or non-isolated.

The following show the D/I channels and their corresponding jumpers :

D/I channel

Jumpers

JA0, JB0

JA1, JB1

JA2, JB2

JA3, JB3

JA4, JB4

JA5, JB5

JA6, JB6

JA7, JB7

Examples are given here to illustrate how to configure the D/I channel. D/I
channel 1 is configured as isolated first, then non-isolated.
