CHIB Hardware Reference Introduction
CTI Products, Inc.
1. Introduction
The CommandSTAR Lite Host Interface Module (CHIB) is a member of the
Monitoring and Control Network (MCN™) family of User Interface Modules.
Hardware specifications and configuration information are described in this
manual.
The CHIB module connects to a CommandSTAR Lite Console. The CHIB
module is used with the MCN RCD software and a Comparator I/O Module (such
as a CIB or AIB) to create a comparator display system on the CommandSTAR
Lite console. For status display, the CHIB module maps the Vote, Receive,
Disable, and Fail indications to the console LEDs. For control, the CHIB maps
the Force Vote and Disable buttons on the console to the corresponding function
on the Comparator I/O Module (AIB or CIB).

CHIB Hardware Reference Theory of Operation
CTI Products, Inc.
2. Theory of Operation
The CHIB module does not provide any direct monitoring or control functions.
Its purpose is to bridge the MCN network to the CommandSTAR Lite console.
The CHIB module emulates a series of I/O modules on the CommandSTAR Lite's
I/O communications bus. Since the console's I/O bus is RS-485, an RS-232 to
RS-485 converter is required between the CHIB and the console.
The CHIB supports multiple baud rates from 9600 baud up to 115.2K baud,
selectable from the rear panel.
The CHIB module can communicate with only one Comparator I/O module (CIB
or AIB). It is limited to the following number of receivers:
CHIB module operating with AIB Module: 14 Receivers
CHIB module operating with CIB Module: 8 Receivers

2.1 Status Indications
The CHIB maps the Voted, Receiving, Disabled and Failed indications from the
comparator to LEDs on the CommandSTAR Lite console.
68-11662-100

CHIB Hardware Reference Theory of Operation
CTI Products, Inc.
The comparator generates the status signals. They are passed through the AIB or
CIB module, through the MCN network, through the CHIB, the 485 converter,
and into the console.
2.2 Comparator Controls
The CHIB maps buttons on the console to the Force Vote and Disable controls on
the comparator. The CHIB forwards the messages on to the AIB or CIB, which
then pass the signals or messages to the comparators.
The CHIB module does not provide direct feedback to the console operator on its
own. Control feedback (the Voted or Disabled LED) comes from the comparator
as described in Status Indications, above.
2.3 Vote Hold Feature
The Vote Hold feature allows an extended Vote Indication on the console. This
provides the operator an indication of which site the last call came from. When
all Vote signals go inactive, the CHIB will hold the last voted indication ON for
the period of time specified on the Vote Hold Time switches.
If a new site votes during the Hold Time, the CHIB will display the new site, and
will re-start the hold Time at the end of that transmission.
Vote Hold times are switch selectable from 0 (off) to 63 seconds, in increments of
1 second.
2.4 Console LED Blank Feature
If the CHIB looses communications with the AIB or CIB for a period of about 20
seconds, it will turn off all console LEDs that are mapped to it. This indicates that
communications is lost. It will set the console LEDs to their proper state when
communications with the AIB or CIB is reestablished.

CHIB Hardware Reference Addressing
CTI Products, Inc.
8. MCN Addressing with CHIB Modules
Like any other module in the MCN family, the CHIB module must have a unique
address on the network.
8.1 AIB or CIB Addressing
Version 100 of the CHIB module uses a fixed address for its companion AIB or
CIB module. It always looks for that module at Group 00 : Module 0.
The AIB or CIB Module that is used with the CHIB module must be
addressed at:
Group 00 Module 0.
8.2 CHIB Address Setting (Group & Module Switches)
The CHIB module is a User Interface module in the MCN system. The MCN
System Manual and System Planner suggest that all User Interface modules be
assigned to addresses starting at Group 80. This recommendation is only for
convenience of planning your address map. The only real limitation on a CHIB
address is that it must be unique. Therefore, in a system with just an AIB (or CIB)
and a number of CHIB modules, the AIB or CIB would be addressed at 00:0 and
the CHIBs would all be set to different addresses.
Some remote applications require multiple consoles to connect to a remote AIB or
CIB using EXB modules. To ensure unique CHIB addressing in these
applications, we ship the CHIB modules pre-addressed. The addresses are unique,
and are based upon the CHIB serial number. The addresses are printed on the
Serial Number tag. The addresses start at Group:Module 00:1 and are
incremented sequentially as shown:
Serial
Number
1001 01 1
1002 01 2
1003 01 3
………
1009 01 9
1010 01 A
1011 01 B
1012 01 C
1013 01 D
1014 01 E
1015 01 F
1016 02 0
1017 02 1
If these addresses conflict with your system's address map, simply change the
CHIB addresses.

CHIB Hardware Reference Addressing

8.3 MCN System Expansion
The CHIB module and its companion AIB/CIB module can reside on an MCN
network with other devices, as long as all MCN units have unique addresses and
the AIB/CIB is addressed at 00:0. It is subject to the same limitations of a
maximum of 20 CIB/AIB/IOB modules and a maximum of 64 modules total on
one physical network.
Multiple CHIB modules can reside on the same MCN network. All CHIBs will
talk to the same AIB or CIB, and all will give the users parallel status and control
functions. One operator can disable a site and an operator at a different console
can re-enable the site later.
A CHIB can talk with only one AIB or CIB module. Since CHIB version 100
looks for the AIB or CIB at a fixed address, they cannot be set to talk to other
AIBs or CIBs that are on the network.
Other CIBs and AIBs can reside on the MCN network, along with PCs using HIBs
or PCLTA modules. The PCs can access all the AIB or CIB modules (including
the one that the CHIB talks to).

CHIB Hardware Reference Remote Operation
CTI Products, Inc.
10. Remote Operation
Because of the protocol between the CommandSTAR Lite console and the CHIB
module, modem connection between the CHIB and the console is not supported.
The CHIB must always be connected locally to the console (within the appropriate
RS-485 or RS-232 distance limits).
If display and control of a remote comparator is required, this can be done with
standard MCN EXB Network Extender Modules. These modules are available in
the following versions:
Model Description
S2-60602 MCN EXB Module with Internal 2W/4W Leased Line Modem

12. Troubleshooting
This table is a list of troubleshooting tips specific to the CHIB module. For
additional troubleshooting tips, refer to the troubleshooting section found in the
Monitoring and Control Network System Manual
Due to the high percentage of surface-mount components, the CHIB is treated as a
field replaceable unit. If any system problems are the result of a malfunctioning
HIB unit, the entire unit must be replaced and returned for repair.

3. RS485 Converter and/or power supply
4. RS-232 Cable from CHIB to RS485 converter
5. Bad CHIB
6. Bad Console
You can use the LEDs on the RS485 converter to help you
troubleshoot this problem.
You should see the console polling the CHIB on LED DS2.
You should see the CHIB respond on LED DS1.
No Status Updates,
Force Votes or
Disables
This could be anywhere in the system.
1. Check the power LEDs on all equipment.
2. On the CHIB module: Is the Console Link LED on?
If not, see the section
3. Is the ACT LED on the AIB/CIB on?
If not, see the section

PROBLEM CAUSE
Bad AIB to Astrotac cable
Bad Astrotac
5. If using a CIB
Bad connections to the comparator
Bad CIB
6. Bad console I/O programming, firmware, or module
Status Updates Okay
but no Force-Votes
or Disables
ACT LED on CIB or
AIB is off
Since status updates are okay, the links between the console and
CHIB are okay. Also, the link between the AIB or CIB and the
CHIB is okay (at least in the AIB/CIB to CHIB direction).
(Remember that switch presses must go through the entire system
and than back to the console before the LED comes on.)
Possible problems:
1. Check to see if the ACT LED on CIB or AIB is off.
- Disconnect all other possible CHIBs, HIBs, and IIBs from
the AIB or CIB. (If any of these devices is accessing the AIB
or CIB, the ACT LED will be on.)
- If the ACT LED on the CIB or AIB is off, see the section
labeled:
"If ACT LED on CIB or AIB is off"
.
2. If using a CIB:
Bad wiring to comparator
Improper option switch setting on CIB
Bad CIB
3 If using an AIB:
Bad AIB or Astrotac comparator
CHIB is not talking to the CIB or AIB.
Possible Problems:
1. Check MCN Network Connections

If you disconnect both the network and the serial cable from the
CHIB, you should see a flash on this LED once every 4-5
seconds. If you see a different pattern than this with both the
cables disconnected, the CHIB is bad.
