3.4 Comparator Interface Module (CIB)
The CIB connects various types of comparators with parallel I/O facilities to the MCN network.
Features of the CIB module include:
•
Parallel bi-directional I/O line connections between the CIB and a parallel I/O
comparator, including Motorola DIGITAC, Spectra TAC, TAC, and Ericsson / GE
analog comparators.
•
Support for up to 8 receivers per module.
•
Provides VOTE, RECEIVE, DISABLE, and FAIL status for each receiver to an MCN
User Interface Module.
•
Allows a User Interface Module to FORCE VOTE or DISABLE any receiver.
•
The CIB can be connected to more than one comparator (with total support for 8
receivers) as long as the comparators are of the same type.
Option switches on the front panel of the CIB configure the type of comparator being used. Refer to
the CIB hardware reference manual for a description of the CIB’s option switches.

3.5 Host Computer Interface Module (HIB) and MCN RCD
Software
The HIB provides a serial interface to a PC and works with the Monitoring and Control Network
Remote Comparator Display (MCN RCD) software to provide comparator monitoring and control.
Features of the HIB module / MCN RCD software combination include:
•
Easy to use software for visual indication of voting system status
•
Monitors up to 4 groups of 16 comparator I/O modules simultaneously (512 receivers).
•
Displays up to 88 receivers viewable on a single screen.
•
Configurable receiver names and screen positions.
•
Displays VOTE, RECEIVE, DISABLE and FAIL information for each receiver on the
screen.
