Installing the module in the module mounting unit connects
the DSI module to the logic power (+5 VDC), necessary to drive
the circuitry, at P1. It also connects P2 to the I/O expander
bus for communication with the controller. P1 and P2 connec-
tions require no additional wiring or cabling.
NOTE: Install a dipshunt on the backplane of the module mounting unit to con-
nect the I/O expander bus between the DSI module and controller. Locate the
modules so the bus can connect the modules or they will not communicate.
The DSI digital input module uses an NTDI01 termination unit
for termination. Refer to Figure
use with the NTDI01 termination unit.
