What it’s about
This service manual explains how to:

Set jumpers on the logic board for RS-232, RS-422, and RS-485
communications.
!
Set jumpers on the I/O filter board to add 100 ohm termination resistors
across the TX+, TX- or RX+, RX- signal lines.
Before performing service on the terminal, check the label on the chassis to
confirm that the unit is a “Series B” terminal.
If the label on your unit indicates that it is a “Series A” terminal, you have an
earlier version of the product and you should refer to the
