3. Refer to
Figure 2
below and locate the jumper locations for EIA-
232/EIA-422 serial interface selection. The jumper locations are
adjacent to the respective serial ports. Each jumper location has
three pins: a center or common pin, a pin marked
232
, and a pin
marked
422
. Each port is configured for EIA-232 or EIA-422
serial interface by positioning four jumpers to connect the
common pin and the
232
pin for EIA-232 (default) or the common
pin and the
422
pin for EIA-422.
IMPORTANT:
For each port, all jumpers must be installed either
to the
232
or
422
side for the desired serial interface.
