ABB INIIT12 INFI-NET Transfer Module single printed circuit board
The INIIT12 module is a single printed circuit board that occu
pies one slot in the module mounting unit, adjacent to its NIS
module. The circuit board contains the serial communication
circuitry necessary for it to communicate with another INIIT12 module.
Two captive latches on the INIIT12 faceplate secure the module
in the MMU card cage. The faceplate contains eight CPU LEDs,
a red/green status LED, and a stop/reset switch.
Interface termination is through a cable connection between
P3 of the INIIT12 module and an NTMP01 Multi-Function Pro
cessor Termination Unit or NIMP01 Multi-Function Processor
Termination Module. INIIT12 module power and I/O expander
bus connections follow the same connector assignments com
mon to most INFI 90 OPEN modules (P1 for power, P2 for I/O expander bus).
