1. Introduction
The Comparator Interface Module (CIB) is a member of the Monitoring and
Control Network (MCN™) family of
Comparator I/O Modules
specifications, special installation, and configuration information are described in
this manual.
The CIB module connects a parallel I/O comparator to the MCN network. The
CIB is used with the comparator and a User Interface Module (such as a HIB or
IIB) and an operator station to create a comparator display system. The
comparator display system provides monitoring and control functions for your
communications system. Receiver states monitored by the CIB include VOTE,
RECEIVE, DISABLE and FAIL. Receiver functions that can be controlled
include FORCE VOTE and DISABLE. The following parallel I/O comparators
are supported by the CIB module:

CIB Hardware Reference Theory of Operation

3. Theory of Operation
This section describes the operation of the CIB module in an MCN comparator
display system.
3.1 Comparator Status
The CIB can accept VOTE, RECEIVE, DISABLE, and FAIL receiver status
indications from the comparator. Some comparators do not support all of these
status monitoring signals. Refer to section 7 for details about wiring the CIB to a
particular comparator. The CIB sends the status information to a User Interface
Module over the MCN network. User Interface Modules, such as the IIB (I/O
Interface Module) or HIB (Host Computer Interface Module) then display the
comparator status information on a console or PC.
3.2 Controlling the Comparator
When a User Interface Module sends FORCE VOTE or DISABLE commands, the
CIB translates the commands and activates the appropriate I/O lines of the
comparator.
The CIB updates the comparator with the latest control information whenever a
FORCE VOTE or DISABLE command is received from a User Interface Module.
3.3 System Example
Figure 3 shows an example comparator display system using the CIB module.
OPERATOR
STATION
Figure 3 - CIB System Example
When the comparator detects that a receiver is active, it drives the RECEIVE
inputs to the CIB. If the receiver is also voted by the comparator, the comparator
drives the VOTE input as well. The CIB detects these inputs and sends receive
and vote messages to the User Interface Module. The User Interface Module then
indicates that the receiver is active and voted. If the User Interface Module is an
IIB, the IIB activates the VOTE and RX outputs for that receiver.

CIB Hardware Reference Theory of Operation
CTI Products, Inc.
If the comparator detects that a receiver has failed, then it drives the FAIL input to
the CIB. Again, the CIB detects this FAIL input and sends a message to the User
Interface Module so that the user can see that the receiver has failed.
From the operator station, the user can generate FORCE VOTE or DISABLE
commands for each receiver in the system. The User Interface Module detects
these commands and sends them to the CIB. The CIB then drives the appropriate
VOTE or DISABLE outputs to the comparator, telling it which receivers were
force voted or disabled.
3.4 Bi-directional I/O Signals
The CIB provides two input/output lines per receiver (VOTE and DISABLE) that
allow both monitoring and control of the signal (Figure 2 shows the equivalent
circuit for the input/output lines). If a receiver is disabled at the comparator, the
CIB will send a message to the User Interface Module so that the disabled
indication for the receiver can be shown at the operator station. Because the
comparator is now driving the input of the bi-directional DISABLE line, the
receiver cannot be re-enabled from the operator station. Pressing a disable button
on the operator station will have no affect on the receiver. If the disable button is
pressed multiple times, you could end up with the disable output latched on
(depending upon how many times the disable button is pressed). If this happens,
when the receiver is re-enabled at the comparator, the operator station will still
show the receiver being disabled when in fact the receiver is enabled. If you reenable a receiver at the comparator and the Disable indication remains on, reenable the receiver through the MCN system.
3.5 Transmitter Status Monitoring and Control
The MCN family includes an auxiliary module that allows monitoring and control
of transmitter sites. This module is called a TSAM Interface Module, or TIB, and
it interfaces between the CIB and CTI Product’s Transmitter Steering Audio
Matrix (TSAM) device (see reference 2). The CIB passes FORCE VOTE
information to the TIB to control or select the active transmitter. The TIB passes
transmitter information to the CIB so that the active transmitter can be displayed
with a User Interface Module that supports display of transmitter status, such as a
HIB with MCNRCD running on a PC.
The CIB will provide this transmitter monitoring and control only if its transmitter
monitoring enable switch, OPTION switch 3, is in the UP position. If this switch
is in the DOWN position, all transmitter monitoring and control is disabled.
The CIB and TIB communicate over the MCN network so no special wiring is
required between the modules.

3.6 Operation With a Spectra-TAC Comparator
Some Motorola Spectra-TAC comparators with the "B" version Signal Quality
Module (SQM) can be damaged when a voltage greater than the comparator's
supply voltage is applied externally on the Disable input. (Motorola fixed this
problem in the "C" version SQM.) CIB modules shipped after January, 2003 are
shipped with E1B In, setting the input pull-up to +5 VDC.
Warning
Some "B" version SQM modules have a problem when they are inserted or
removed under power. Depending upon which pins connect first, the module may
be destroyed if there is an external connection to the Disable pin. The module
will try to power itself through the Disable pin and will destroy IC U3.
When inserting or removing the SQM from the comparator shelf, be sure to
first disable the module from the front panel switch on the SQM
assure that the Disable input is grounded. After the module is re-inserted, turn off
the Disable switch.

3.7 Operation With a Digitac Comparator
Installation Notes
A Digitac Comparator can be connected to a CIB module with a straight
•
through 50-pin cable. Jumper E1-A and E1 B must be out. See the CIB to
Digitac wiring chart. Be sure to set the Option Switches for Digitac
Comparator.
The switches and jumpers on the CIB module are difficult to reach after the
•
module is mounted to the comparator. Always set the switches and jumpers
for the CIB module before installing it on the back of the Digitac comparator.
Fail & Disable
The Motorola Digitac Comparator drives its Fail/Disable line low when:
A receiver input has failed (loss of status tone).
•
A receiver is disabled from the switch on the front panel of the comparator.
•
In either of these two cases, the MCNRCD software will display a “FAIL”
indication on the PC.
The MCNRCD software will display a “DISABLE” when the receiver site is
disabled from the PC, since the CIB is generating the Disable signal..
Coded Mode
The Digitac "Mode" (Coded) outputs appear on CIB "Fail" inputs. When you set
the CIB switches to Digitac mode, the CIB module ignores the Fail inputs. If the
switches are set improperly, you will see a "Fail" indication whenever the Digitac
receives a Coded transmission.
