4. Align the module with the guide rails in the module mount-
ing unit. Gently slide the I/O module in until the front panel is
flush with the top and bottom of the mounting unit frame.
5. Push and turn the two captive retaining screws on the I/O
module faceplate one half turn to the latched position. It is
latched when the slots on the screws are vertical and the open
ends face the center of the I/O module.
The I/O modules have three card edge connectors to supply
power, connect I/O expander bus communication and provide
digital I/O (P1, P2, P3 respectively).
Installing the I/O module in the module mounting unit con-
nects the I/O 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 controler. P1 and P2
connection require no additional wiring or cabling.
NOTE: You must install a dipshunt on the backplane of the module mounting
unit to connect the I/O expander bus between the I/O module and the control-
ler. Locate the I/O modules so the I/O expander bus can connect the modules
or they will not communicate.
The I/O modules use a NTCS04 termination unit for termina-
tion. Refer to Figure
