IIB™ Input/Output Interface Module
for MCN™ Monitoring and Control Systems
Introduction
The IIB Input/Output Interface Module is part
of CTI Products’ Monitoring and Control
Network (MCN™) system. It connects a
parallel operator display device (such as a
console) to the MCN Network.
The IIB is used with AIB ASTRO-TAC™
Comparator Interface Modules to provide
voting status indications (Vote, Receive,
Disable, and Fail) to a console. It also allows
the console operator to Force-Vote and
Disable receivers.
The IIB can also be used with CIB Comparator
Interface Modules to extend the comparator
display and control for other comparators
(Digitac, Spectra-TAC, TAC, and EGE) over a
long distance.
The IIB module takes MCN status messages
(Vote, Receive, Disable, and Fail for
comparators) from the network and provides
output signals to the console I/O boards. It
also takes Force Vote and Disable output
signals from the console and sends
commands to the comparator interface
module over the network.
The IIB Input/Output Interface Module is
compatible with:
 MCN CIB Comparator Interface
Modules
 MCN AIB ASTRO-TAC™ Comparator
Interface Modules
 Consoles with parallel inputs & outputs
Extend your Comparator Status Display
and Control to Your Console!
In some systems, comparators are not located
close to the console electronics. With an IIB
and a CIB or AIB, you can bring the
comparator status information back to the
console over an easy to install serial network
cable, thus reducing wiring costs.
For ASTRO-TAC™ comparators, the IIB,
along with an AIB, provides the parallel
outputs a console needs to display the
comparator Vote, Receive, Disable, and Fail
indications.
With a comparator display at the console, an
operator can see at a glance which receivers
are receiving, voted, or failed, and which
receiver is causing your system problems. A
Force-Vote function permits audio monitoring
of each receiver site. A Disable function shuts
down bad receivers until repairs are made.
Repair Voting System Problems Efficiently!
With the MCN Remote Comparator Display,
your operators can provide a technician with
an accurate description of the system failure.
By isolating a failure to a specific voting
receiver, valuable technician time is saved
and receiver down-time is reduced.
The system can help pinpoint intermittent
system problems, eliminating repeated service
calls to the comparator just to isolate a bad
receiver.
System Options
The following are some of the MCN system
options available to work with the IIB module:
