INIIT12 INFI-NET to INFI-NET Transfer Module

The NIS module works in conjunction with the INFI-NET to

INFI-NET transfer modules. This allows any node to communi

cate with any other node within the INFI-NET system.

The NIS module is a single printed circuit board that occupies

one slot in the module mounting unit (MMU). The circuit board

contains microprocessor based communication circuitry that

enables it to interface with the INFI-NET to INFI-NET transfer

modules via the I/O expander bus. Both the INFI-NET to

INFI-NET interfaces require a specific interface module and an

NIS module (the INIIL02 module requires two NIS modules).

Two captive latches on the front-mounted faceplate secure the

module to the MMU card cage. There are 16 LEDs on the face

plate that display error codes or event/error counts.

Each NIS module connects to its INFI-NET communication

loop by a cable connected to an NTCL01 Communication Ter

mination Unit or NICL01 Communication Termination Module.
