The IMCIS12 and IMQRS12 modules insert into a standard
INFI 90 OPEN module mounting unit (MMU) and each occupies
one slot. Use the following installation procedures.
1. Verify the slot assignment of the module.
2. Verify that a dipshunt is in the I/O expander bus socket on
the MMU backplane between the I/O module and the control
module.
3. Connect the hooded end of the termination cable from the
TU/TM to the MMU backplane. To do this, insert the connec-
tor into the backplane slot in the same slot as the one assigned
to the I/O module. The latches should snap securely into
place.
4. Align the module with the guide rails in the MMU; gently
slide the module in until the front panel is flush with the top
and bottom of the MMU frame.
5. Push and turn the two captive retaining screws on the
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 module.
WIRING CONNECTIONS AND CABLING
The CIS and QRS modules have three card edge connectors to
supply power, connect I/O expander bus communication and
provide digital I/O (P1, P2, P3 respectively).
Wiring
Installing the module in the MMU connects 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 communica-
tion with the control module. P1 and P2 connection require no
additional wiring or cabling.
NOTE: You must install a dipshunt on the backplane of the MMU to
connect the I/O expander bus between the I/O module and the con-
trol module. Locate the modules so the bus can connect the mod-
ules or they will not communicate.
Cable Connections
The CIS and QRS modules use either a NTCS04 (termination
unit) or NICS01 (termination module) for termination. Refer to
Figure
to determine the correct cables.
WARNING
Disconnect power before installing dipshunts on the MMU
backplane. Failure to do so will result in contact with cabinet
areas that could cause severe or fatal shock.
