Section 1. Introduction and M anual Overview

1. Introduction and Manual Overview

The Monitoring and Control Network (MCN™) Comparator Display system provides remote monitoring and control for voting receiver systems. It extends the comparator status indicators for display on a PC and allows an operator or technician to force-vote and disable receivers from a PC. With the MCN system you can control and display multiple comparators from a single point or multiple points. It works with DIGITAC, Spectra-TAC, TAC comparators and Ericsson / GE analog voters.

The MCN system can also be used to provide status and control input/output to a console for ASTROTAC systems. ASTRO-TAC systems with 8 or fewer receivers per channel can be monitored and controlled on a PC. This is a major convenience since ASTRO-TAC comparators do not have any indication of active or voted receivers. The AIB ASTRO-TAC Interface Modules are available exclusively through Mo torola.

The MCN Comparator Display System is targeted for the following applications:

• Systems which need comparator display for dispatchers

• Systems that need remote comparator display and control for technicians

• Critical comparator systems which require failure logging

• Large comparator systems (wide area or large number of channels)

• Ribbon Systems

• Analog Trunking systems with voting receivers

• ASTRO-TAC systems that require display of comparator status for a dispatcher or technician on a

PC or a console

• Any voting system that needs rapid maintenance and diagnostics.

Typical customers are:

• Public Safety Dispatch Centers

• Police and Fire Departments

• State Police systems

• State and Local Governments

• Turnpike systems

• Transit authorities

• Utilities

• Federal Government systems

• Forestry / Conservation

Features:

• Remote display of comparator status (Vote, Receive, Disable, Fail)

• Remote control of receivers (Force Vote, Disable)

• Remote Comparator Display and Control on a PC

• Intuitive operation

• PC based system saves space over a comparable button and LED system

• Can provide Input/Output signals for various button and LED or CRT consoles.

• Error Logging for Receiver Failures on PC systems

Benefits:

• Easy RF communications system troubleshooting

• Remote disabling of noise-producing equipment

• Automatic logging of RF system malfunctions

• Quicker system maintenance

• Lower system down time

Section 1. Introduction and M anual Overview

1.1 MCN System Overview

Figure 1 shows a basic MCN comparator display system. The MCN system is made up of two modules, a Comparator I/O Module and a User Interface Module. The Comparator I/O Module provides the hardware interface to the comparator. The User Interface Module provides the mechanism for the user to monitor and control the comparator.

Figure 1 - Basic MCN System

The Comparator I/O Module and the User Interface Modules connect with a single cable between the network ports of the modules, simplifying system installation. Standard systems can include up to 20 Comparator I/O Modules in a single network segment. Larger comparator display systems consisting of multiple network segments tied together with routers/repeaters can be custom configured by CTI Products, Inc.

Together, the Comparator I/O Module and the User Interface Module provide a simple, cost effective way to control your comparator system. Because of the MCN system’s modular design, your comparator display system can easily expand as your communications system grows.

Page 2 MCN Comparator Display System Planner

Section 2. System Operation

2. System Operation

This section describes the basic operation of both Comparator I/O Modules and User Interface Modules in a comparator display system. Two systems are described:

• A PC based system connected to three DIGITAC, Spectra-TAC, or Ericsson / GE comparators,

and

• A console-based system connected to an ASTRO-TAC comparator. In an MCN system, the Comparator I/O Module accepts VOTE, RECEIVE, DISABLE, and FAIL

receiver status messages from the comparator and sends them to a User Interface Module over the MCN network. User Interface Modules then display the comparator status information on a console or PC.

Likewise, when a User Interface Module sends FORCE VOTE or DISABLE commands, the Comparator I/O Module translates the commands and sends them to the comparator.

2.1 PC-Based System for Digitac, Spectra-TAC, or Ericsson Comparators / Voters

2.1.1 System Description

Figure 2 shows a small system made up of three Comparator I/O Modules (the CIBs) and one User Interface Module (the HIB). The PC can monitor and control all three comparators from a single screen. When a receiver is force voted from the PC, a FORCE VOTE message is generated by the MCN RCD software and sent to the CIB that is controlling that particular receiver. When the CIB receives the FORCE VOTE message, it will drive the receiver’s VOTE output line to signal the comparator that the receiver is being force voted. A similar process occurs when a receiver is disabled from the PC.

Going the other direction, when the comparator detects that a receiver is active, it will drive the RX input of the CIB. The CIB will then generate a RECEIVE message and send it to the HIB so that the active receiver can be shown on the PC screen. A similar process occurs when the comparator generates a Vote (driving the CIB’s VOTE input) or a Fail (driving the CIB’s FAIL input) signal.

Section 2. System Operation

2.1.2 MCN Remote Comparator Display PC Software Operation

Two programs make up the MCN RCD software package. They are:

• MCNCFG.EXE - the configuration program

• MCNRCD.EXE - the runtime Remote Comparator Display program.

The MCNCFG program is run by an engineer or technician to build the configuration files when the system is installed or changed. The MCN RCD program is run by a dispatcher or technician to display the status of the voting system.

The MCN RCD software allows the operator to see which receivers are receiving, voted, disabled, failed or in an error condition on the PC. It also allows the operator to monitor and disable receivers with the Force Vote and Disable functions.

2.1.3 System Hardware Requirements

Two components are required for the MCN RCD system.

1. Host Computer Interface Module (HIB)

2. A PC to run the MCN RCD software with the following minimum configuration:

• 25 MHz 386 PC (for 1-9 Comparator I/O Modules)

• 50 MHz 486 PC (for 10-20 Comparator I/O Modules)

• EGA or VGA adapter and monitor

• 2 MB RAM

• 10 MB free disk space

• Microsoft or Logitech mouse

• one open serial port capable of 38.4k baud

• MS-DOS 5.0 or higher

Page 4 MCN Comparator Display System Planner

2.1.4 PC Display Screen Layout

A typical receiver screen is shown below:

Section 2. System Operation

Figure 3 - Receiver Activity on an RCD Screen

The Receiver Display Screen has the following items:

• Menu Bar Located at the top left of the screen

• Screen Name Located at the top center of the screen

• Channel Titles Highlighted areas that extend across the receiver

Name column and the Receiver Indicator Column

• Receiver Names Located on the left side of the four columns in the

body of the screen

• Receiver Indicators Located to the right of the Receiver Names

• Error Status Line Present on the bottom line of the screen when an

error has occurred and the “Show Errors On Screen” option is enabled.

The Receiver Indicators display the status of the receivers. The following status indications can be displayed:

Status Indicator Background color Text Color

No Activity Blue Vote Vote Green White Receiving Rx Lt Gray Dark Gray Disabled Dis Y ellow Black Failed Fail Red White Error Err Brown Yellow

The status text and colors can be custom configured at time of installation.

MCN Comparator Display System Planner Page 5

Section 2. System Operation

2.1.5 Controlling Receivers

You can use the MCN RCD program to control the receiver operation at your remote comparator. You can manually FORCE VOTE a receiver from the PC and listen to its audio quality over your system. You can also DISABLE a receiver that is defective or has a bad phone line. When the receiver or phone line is repaired, you can re-enable the receiver from the PC. Receivers can be controlled with either the mouse or keyboard.

2.1.6 Error Logging

The MCN RCD program can log system errors on a PC. The PC will log whenever a receiver fails or becomes disabled. It will also log when the receiver returns to a normal condition. Logging entries include a time and date stamp, the receiver status, the group, module, and receiver number, the receiver name, and the comments for that receiver. The log entries are stored in an ASCII text format on the disk. The error logging feature is available only when the PC is connected to the MCN system. No error information is logged when the PC is off-line.

2.1.7 MCN RCD Softwa r e Configuration

The MCN Remote Comparator Display software includes a configuration program, MCNCFG.EXE, which allows you to custom-configure your system. The configuration is a two-step process:

1. For each Group of 16 comparator I/O modules (CIBs and AIBs), enter the receiver names, channel

names, and comments for each receiver.

2. Build the screen by entering channel titles and then by placing the receivers that were previously

defined using a “point and shoot” selection method.

An MCN Group Configuration file (.GCF extension) contains all of the receiver information for a particular set of MCN Comparator I/O Modules, all addressed into a single MCN Group.

MCN Screen Files (.MSF extension) contain a list of receivers to be displayed on the current CRT screen and where they will appear on the screen. One MCN Screen File supports four different Group Configuration Files so that receivers from four different MCN Groups can be monitored and controlled from the same screen.

Up to 88 receivers can appear on the PC display. For many systems this will allow an operator to view all of the receivers in a voting receiver system. On larger systems as many as 50 screens can be created to display a system’s receivers.

2.2 Console-Based System with ASTRO-TAC Comparator

2.2.1 System Description

The following diagram shows a simple system for ASTRO-TAC comparator display and control on a console. The AIB ASTRO-TAC Interface Module is connected to the comparator via a serial cable. The IIB I/O Interface Module is connected to 16-I/O boards in a Central Electronics Bank (CEB).

The status can be displayed on a console with parallel I/O lines for Vote, Receive, Disable, and Fail indicators and switches. The console is configured just as if it is connected to a standard analog comparator such as a DIGITAC or Spectra-TAC comparator. In this configuration, the comparator display and control will be running thr ough the console electronics.

Section 3 System Components and Specifications

3. System Components and Specifications

3.1 Module Types

The MCN Module types consist of five classes or types of modules:

• Comparator Input/Output Modules

• User Interface Modules.

• Transmitter Steering Interface Modules

• System Extender Modules

• Router and Repeater Modules

3.1.1 Comparator Input Output Modules (CIBs and AIBs)

Comparator I/O Modules provide the physical connection between the comparator and the MCN network. Depending on the features provided by the comparator, the connection to the comparator may be discrete I/O points that are hard wired to the comparator, or a simple RS-232 cable connected to a communications port on the comparator.

The following are the MCN Comparator I/O Modules:

• Comparator Interface Module (CIB)

• ASTRO-TAC Comparator Interface Module (AIB) (available exclusively through

Motorola)

Each module is briefly described in its own section. For more information about features specific to an individual module, refer to its hardware reference manual.

3.1.2 User Interface Modules (HIBs and IIBs)

An MCN User Interface Module connects the MCN network to various User Interface devices. The user interface may be simple lights and push buttons, such as a console, or the user interface may be a program running o n a PC to monitor and control t he comparator .

The following are CTI Products’ MCN User Interface Modules:

• Host Computer Interface Module (HIB) for PC interface (serial)

• Input/Output Interface Module (IIB) for console interface (parallel)

Each module is briefly described in its own section. For more information about features specific to an individual module, refer to its hardware reference manual.

MCN Comparator Display System Planner Page 9

Section 3 System Components and Specifications

3.1.3 Transmitter Steering Interface Modules (TIBs)

The Transmitter Steering Interface Modules (TIBs) work in conjunction with the CIB comparator Interface Modules and external Transmitter Steering equipment, such as the TSAM Transmitter Steering Unit from CTI Products. This interface provides monitor and control of transmitter sites from a PC with a HIB as the Operator Interface Module. The CIB is the only Comparator I/O Module that operates with the TIB and the HIB is the only User Interface Module that operates with a TIB.

The TIB is used in systems that have multiple transmitters, with each transmitter associated with one or more receivers and that use the TSAM to provide steering for the transmitter sites. The TIB will translate a FORCE VOTE command for a particular receiver into a FORCE TX command that commands the TSAM to steer to the transmitter associated with the receiver being FORCE VOTED. The TIB can also monitor the TSAM for the active transmitter site for display on a PC.

3.1.4 System Extension Modules (EXBs)

The EXB modules are used in pairs to connect two MCN networks together or to extend the length of an MCN network beyond 4000 feet. Typical applications include:

• Extending MCN Networks over phone lines

• Display and control multiple remote comparator locations at a central location

• Connects multiple local PC displays to a remote MCN network using 1 phone line

• Zone Comparators

• Master/Slave Comparators (Sub-Comparators)

• State-Wide / Regional / City-Wide voting systems

The EXB System Extender Modules use any analog or digitized analog channel (including standard 2wire or 4-wire leased lines, or microwave channels) which is capable of carrying V.32 terbo standard modem signaling,. Data transfer between distant networks is "live", delayed only by the transit time through the EXB mod ul es and the data rate across the modem link.

3.1.5 Router and Repeater Modules

Router and repeater modules are available on special order to extend the MCN network in the same building. They can also extend the network capacity to greater than 64 modules or 20 Comparator Interface Modules. The implementation of systems with these modules is customer-specific. CTI Products applications engineers will be happy to assist you in designing a custom system that extends past the normal limits of the MCN network.

• Allows logging (to the screen and/or to a disk file) of receivers that fail or become

disabled. Logging may be enabled or disabled by the operator.

• Modem support allows remote monitoring and control.

Because the module can be used with modems for remote operation, a technician no longer has to travel to the comparator site to diagnose system problems since he can monitor and control the comparator from a properly equipped PC in their shop.

3.6 Input/Output Interface Modul e (IIB)

The IIB provides discrete, parallel Input/Output points for monitoring and control of comparators. IIB outputs can be connected to LEDs for viewing comparator status and inputs can be connected to switches for control of comparator functions. Features of the IIB include:

• Support for up to 8 receivers.

• Status Outputs for each receiver which includes VOTE, RECEIVE, DISABLE, and FAIL.

• Control Inputs for each receiver include FORCE VOTE and DISABLE.

• Link Fail output which indicates a failed serial link with the ASTROTAC comparator.

This output takes up one receiver output.

3.7 Transmitter Steering Interface Module (TIB)

When a receiver is FORCE VOTED from the PC, the HIB sends a FORCE VOTE command to the CIB, the TIB that is associated with that CIB also receives the command and activates the TX Select line for the specified receiver/transmitter. The TIB then activates the Force Select output line for approximately 100 milliseconds. After this 100 milliseconds, the TX Select lines and the Force Select line are deactivated so that the TIB can resume monitoring the transmitter status.

The TIB monitors the TSAM’s 8 TX Select lines to determine which transmitter is currently active. Whenever the TSAM steers to a transmitter, the TSAM updates the TX Select lines to indicate the currently active transmitter. The TIB sends the status information to a HIB over the MCN network so that the transmitter status can be displayed on the PC.

4.2 Parallel I/O Cabling

Parallel I/O cables are standard 25-pair cables and are used with CIB Comparator Interface Modules and IIB I/O Interface Modules. Three versions are available, a 10 and 25 foot male to male cable for connection to punch blocks, and a 25 foot male to blunt end cable for wiring directly to the back of a Spectra-TAC comparator or Ericsson / GE Analog Voter.

4.2.1 DIGITAC Comparators Cabling with DIGITAC Bracket and Cabling

For CIBs connected to DIGITAC comparators using the DIGITAC Bracket and Cable, the CIB connects to the D IGITAC through a ribbon cable and no extra parallel I/O cable is required. The cable and punch block that are normally ordered to connect to P805 on the DIGITAC comparator will instead be connected to the third connector on the ribbon cable.

If a cable and punch block weren’t ordered for the DIGITAC, you can order a male to male cable and punch block.

4.2.2 DIGITAC Comparators Cabling with DIGITAC Rack or Wall Mount

For CIB modules which mount using a rack mount or wall mount, you will need a parallel I/O cable. You can order either:

• Male to male 25-pair cable for use with a dedicated punch block

• Male to blunt end 25-pair cable to punc h down to an existing punc h block.

Page 18 MCN Comparator Display System Planner

Section 4. System Installation Options

4.2.3 Spectra-TAC and TAC Comparators and Ericsson Analog Voters

There are 3 general ways to connect to these types of comparators:

1. Male to male 25-pair cable to punch block with field wiring to back of comparator. This option

provides the most flexibility, but it requires a punch block and a place to mount it.

2. Male to blunt end 25-pair cable wired directly to the back of the comparator card cage. This

method eliminates the need for a punch block and works well if the CIB modules and comparators are mounted close in the same rack so that you can disconnect the cable from the CIB module if the comparator card cage must be removed.

3. A short 25-pair pigtail cable with a female connector wired directly to the comparator card cage.

A male to male 25-pair cable then connects the CIB to the pigtail. This method eliminates the need for a punch block, but still allows the comparator card cage to be removed from the rack for service, especially if the CIB module is mounted in a different equipment rack. Note that the female pigtail cable is field fabricated.

4.2.4 IIB I/O Modules:

There are two parallel cabling options for IIB modules:

• Male to Male 25-pair cable and punch block with cross-connect to the comparator interface punch

block(s) for the console module. This is the most flexible option, but it does require extra punch blocks and mounting space.

• Male to blunt end 25-pair cable, punched down to the existing punch block(s) for the console I/O

module. This option is less expensive and takes up less space. In the case of the Motorola Centracom series II consoles, one IIB module can connect to two comparator interfaces in the CEB. With this option, you will have to split the cable apart and connect to two punch blocks, or to both sides of a split punch block.

4.3 Network Cabling

MCN modules communicate over a network cable. Specifications for network cabling are the following:

• 4 pair level IV or V unshielded, 24 AWG, twisted pair cable (EIA/TIA 568B).

• Maximum of 64 modules can be connected together, with a limit of 20 Comparator I/O Modules

per network segment.

• Maximum cable length is 4000 feet.

• Straight through connections.

MCN Comparator Display System Planner Page 19

Section 4. System Installation Options

One side of the network cable is shown below. This diagram details the pinout and twisted pair configuration of the cable.

1 2 3 4 5 6 7 8

When cabling your system, daisy-chain the modules together and insert a network terminator into the unused port o f t he first module and the unused port of t he last module in the cha i n. An example of what the terminator looks like is shown in Figure 11.

Use of standard length cables from CTI Products is highly recommended to provide best system performance. Standard lengths are available up to 1000 feet. Standard lengths can be combined with cable couplers to create desired length cables. Custom lengths can also be ordered.

If you do provide your own cable, be sure it meets the specifications above. The system will not work with ordinary telephone cable.

The MCN network cable is not rated for outdoor use. The MCN system is not rated for cabling running exposed outdoors, for example with overhead lines, due to possible lightning surges.

If you are providing your own cable for a run longer than 100 feet, a new power supply will be required at the far end. You may use 2-pair Level IV or Level V cable instead of 4-pair. In this instance, connect just the data pair (Pins 1 and 2).

4.4 Power Requirements / Power Supply Specifications

Power input for all MCN modules is 10 to 32 VDC, with most modules requiring 2 W nominal. AC power supplies are available that provide 18 VDC at 800 mA. MCN systems have been fully tested for appropriate immunity to harmful electrical noise and electrical impulses when assembled with these power supplies. Operation with other, non-qualified power supplies could yield lower system performance and may void US, Canadian, or European emissions and susceptibility approvals.

The DC IN receptacle of all MCN modules can accept either polarity configuration from the input power plug.

The MCN system provides a unique way to distribute power to multiple modules from a single power supply. The network cable used for module communication also contains power lines so that the power from a power supply can be distributed along with the communication lines. The limits of this power distribution are the following:

• A maximum of four modules can be powered from a single power supply.

• The maximum cable length between the modules that share a power supply is 100 feet.

To create this power distribution (refer to Figure 12), simply connect the power supply into your first module. Then, connect the NETWORK OUT port of that module to the NETWORK IN port of the next module. Continue connecting NETWORK OUT ports to NETWORK IN ports until all modules are connected. If you need to add more power supplies to the system due to power distribution limits, simply connect another power supply into the DC IN port of a module. This new power supply then provides power for the module it is connected to as well as all modules from that module’s NETWORK OUT port or until another power supply is encountered.

Section 5 Designing and Ordering a System

5. Designing and Ordering a System

The following procedures should be followed when designing and ordering an MCN system.

Step Operation

1 Determine the type of comparator in the system: Spectra-TAC, DIGITAC

TAC, or ASTRO-TAC comparator or Ericsson / GE analog voters. 2 Determine the total quantity of comparators in the system. 3 Determine how many receivers are connected to each comparator. 4 Determine the type and quantity of operator interface required (PC or

console based). 5 For console-based systems, determine the number of I/O cards, operator

interface modules, and I/O programming options required. Order these

items from your console vendor.

For instance, in Motorola Centracom Series II consoles, B1426 Modules

are required in the Central Electronics Bank (CEB) for every 4 receivers

and B1439 Comparator Display Modules are required for button and LED

consoles for every 4 receivers. 6 Follow the intructtions in the Designing an M CN system section.

MCN Comparator Display System Planner Page 23

Designing an MCN system

5.1 Designing an MCN system

Before designing an MCN system, follow steps 1-6 on page 23.

5.1.1 Network Planning / Equipment Location

Typically, comparator interfaces (CIBs and AIBs) will be mounted near the comparators, either in rack mounts or in DIGITAC Bracket and Cable Rear Mount.

For DIGITAC comparators, the DIGITAC Rear Mount is the preferred method to mount the CIB because it includes a ribbon cable for quick and easy connection. It also conserves rack space. For other comparators, the Quad Rack Mount is preferred. It can mount (4) modules.

For Console Logic I/O, the IIBs will mount near the console electronics (CEB). This may be local to the comparator and AIBs, in which case they can mount to the same rack mounts as the AIBs. They may also be located at an extended distance from the comparators. In which case, they can be rack mounted near the CEB and connected to the comparator interfaces via an extended length network cable. These are called Extended IIBs in the ordering worksheet.

HIBs connected to modems will normally be mounted locally to the CIBs.

HIBs connected directly to PCs will mount close to their PCs and will connect to the comparator interfaces through an extended length network cable. Extended HIBs can be mounted with their own rack mount, a wall mount, or placed in the bottom of a console enclosure without a mount.

5.1.2 AIB Considerations

AIB modules are ordered per ASTRO-TAC RF channel. Only one AIB module is used per ASTROTAC comparator, up to 13 receivers. Each channel will need its own AIB module. Remember that PC display systems can only display and control the first 8 ports on an ASTRO-TAC comparator. AIB modules are available exclusively through M otorola.

5.1.3 IIB Considerations

IIBs monitor and control ASTRO-TAC receiver ports in banks of 8. You will need 1 or 2 IIBs per AIB. Note that consoles and transmit-only base stations each take up a port. If you use the Link Fail indicator option on the IIB, it will take up the highest receiver in the system (#8 or #16).

If you have any receivers on ports 9-13, you will need (2) IIBs per AIB.. Also, if you have a receiver active on Port 8 and you need the Link Fail Indication option, you will need (2) IIBs per AIB. Otherwise, you will need (1) IIB per AIB.

If you will be using both logic I/O (IIBs) and PC display (HIBs), please note that the console display can get out of sync since it has a bi-directional Disable line. See the Appendix E System Limitations when using HIB and IIB Modules Together section of this system planner for more details.

5.1.4 CIB Considerations

Normally, you will order one CIB for each comparator card cage. This corresponds to 8 receivers on Motorola comparators. Even if not all the receivers are used, configuring the system for the maximum number of receiver slots allows for easy system expansion when receivers are added. This is especially true in the case of DIGITAC comparators. When you use the DIGITAC Bracket and Cable, you must dedicate a CIB to each DIGITAC cage.

Typically, divide the number of receivers per channel by 8 and round up to the next whole number. For example, a 20 channel DIGITAC system will have 3 card cages and would require 3 CIBs.

Page 24 MCN Comparator Display System Planner

Designing an MCN system

Can you connect multiple channels (card cages) to a single CIB to save cost? Yes, so long as you are connecting only one type of comparator to one CIB. For example, in a system that had 6 Spectra-TAC channels each with only 4 receivers, one CIB could be connected to 2 channels, and only 3 CIBs would be required, but there would be no pre-wired expansion. When you control multiple channels or comparator card cages, be sure to use the punch block wiring option to make the field wiring easier. If you control multiple DIGITAC cages from one CIB, you can’t use the DIGITAC bracket and ribbon cable mount.

A standard configured system can have a maximum of 20 comparator modules (CIBs and AIBs) on a network segment. Larger systems can be custom-configured by CTI Products, Inc. If you need more than 20 CIBs and AIBs on one network, call a system engineer at CTI Products, Inc.

5.3 Custom System Configuration Worksheet

Step Operation

1 Determine the number of networks required.

With PC Display, typically only 1 network will be used, so that the PC can see all the comparators. If you are using ASTRO-TAC comparators and Logic I/O (AIBs and IIBs) exclusively, they can be

configured as multiple stand-alone networks. Contact a systems engineer from CTI Products, Inc. at (513) 595-5900 if you have any of the

following systems:

Remotely located (> 4000 ft.) comparators

•

Multiple PC Displays and one or more remotely located comparators

•

Sub-Comparators

•

Greater than 20 total CIBs plus AIBs

•

Greater than 64 total modules (CIBs, AIBs, HIBs, IIBs)

•

Transmitter Steering (TSAM) Units and TIB modules

•

For each network, do the steps 2 through 20.

2 AIB ASTRO-TAC Interface Modules and cables:

Count the number of AIB ASTRO-TAC Interface Modules to order. If you do not have ASTROTAC comparators, skip to step 3:

CDN6119 AIB ASTRO-TAC Interface Module Qty: _________ Order the same quantity of AIB to ASTRO-TAC serial cables:

CDN6131 AIB to ASTRO-TAC cable (10 ft.) Qty: _________ Order these items from Motorola.

3 IIB Logic I/O Interface Modules:

If you need logic I/O to connect to the I/O lines of a console, calculate the number of IIB Input/Output Modules required. If you want to use only PC display, skip ahead to step 4.

IIBs monitor and control ASTRO-TAC ports in banks of 8. You will need 1 or 2 IIBs per AIB. An IIB can also monitor one CIB module. See IIB Considerations section for more details.

Count the number of IIBs required for all channels and order that quantity of IIBs: S2-60433 Input/Output Interface Module (IIB) Qty: _________

4 CIB Comparator Interface Modules:

Calculate the number of CIB Modules to order. You will need CIB modules for DIGITAC, SpectraTAC, and TAC comparators and Ericsson / GE analog voters. If you do not have these type of comparators, skip to step 5.

Enter the number of CIBs required for each comparator type and order the total quantity:

CIBs for DIGITAC _________ CIB for Spectra-TAC _________ CIBs for TAC _________ CIBs for Ericsson / GE analog voters _________

7.3 Example 3 - Extended Distance Spectra-TAC or Ericsson Comparator Connected to a Console -- 16 Receivers

A multiple comparator system is shown in Figure 17. This system implements monitoring and control of 3 different comparators from one console.

This system assumes the following:

• Spectra-TAC or Ericsson / GE Comparator, 16 Receivers maximum

• Console Display

• CIBs will be rack mounted

• IIBs will be rack mounted

• 400 feet between comparators and console electronics

• Punch blocks are used for connection to comparators and to the consoles (Note that the punch

blocks are not shown on the diagram.)

Why in the world would we use an MCN system to connect the comparators to the console electronics? Can’t they be connected directly? Normally, they can. In this case, the console electronics enclosure is located 400 feet from the comparators. For the logic signals involved, there is a typical limit of about 200 cable feet between the comparator and the console electronics. We are using the MCN system as wire extenders to get rid of the 200 ft limitation. Only a single network cable for the MCN system has to be run the 400 ft. The MCN system can function to 4000 feet. If more than 4000 feet are required, CTI Products can furnish MCN EXB System extender Modules which can extend the network over telephone lines.

Notice that in this system, one CIB module is being used to control receivers from two comparators (comparators 1 and 2). The only requirement for this setup is that both comparators 1 and 2 are the same type (in this case they are both Spectra TAC or both Ericsson / GE). Comparator 3 does not have to be the same type as comparators 1 and 2 since it connects to a different CIB. We are using punch blocks in this system so we can easily connect comparators 1 and 2 to CIB module 1.

7.4 Example 4 - 24 Receivers with Multiple Operator Positions

The example in Figure 17 shows a much larger system than the previous examples. Three CIB modules are used to control a total of 24 receivers. The three IIB modules can be used to provide control of all receivers from the main console. Each PC in the system can control all receivers as well. The HIB modules provide both local and remote control of all receivers. With the HIB connected directly to the modem, the comparators can be accessed from anywhere that has a dial-up phone line.

This system assumes the following:

• (2) Spectra-TAC Comparator (comparators 1 & 2), 8 receivers each

• (1) DIGITAC Comparator (comparator 3), 8 receivers

• 1000 feet between comparators room and the CEB room

• Local PC display in the console electronics room

• Console Display using Ext ended IIBs

• All comparators are mounted in the same rack.

• The Dial-up HIB and the CIBs for the Spectra-TAC comparators will be rack mounted in same

cabinet as the comparators

• CIBs will be connected to Spectra-TAC comparators with blunt-end cables wired directly to the

back of the comparators.

• The CIB for the DIGITAC comparator will mount to the rear of the comparator with a Digitac

Bracket and Cabling kit.

• IIBs will be rack mounted in the CEB room

• The HIB in the CEB room will be mounted under a desk-top using a wall-mount kit.

7.6 Example 6 - Multiple Remote PCs using EXB System Extenders

When only one remote PC is needed to monitor remote comparators, a HIB Host Computer Interface Module and a pair of modems are used. If multiple PCs are required, that method would require multiple telephone lines, one for each PC.

Figure 19 shows a way to connect multiple PCs to remote comparators using only one phone line. pair of EXB System Extender Modules extend the MCN network at the remote site to the local site. The remote network of CIB Comparator Interface Modules is essentially re-created at the local site. Multiple PCs are then connected to the local MCN network through standa rd HIB Host Computer Interface Modules. The number of PCs at the local site is limited only by standard MCN system limitations.

7.7 Example 7 - Multi-Site Comparator Networks Zone & Master/Slave (Sub) Comparators

Many voting systems covering a large geographic area will have comparators located at multiple sites. In this way, comparators for particular zones are located close to their receivers, with the voted audio brought back to the dispatch center on a single phone line for each zone. This greatly reduces the length and cost of the associated telephone lines.

Some state-wide or city-wide systems use Master-Slave (or Sub-Comparator) systems. In these systems, the City-Wide or State-Wide channel is broken into zones, each with its own comparator, called Slave or Sub-Comparators. The voted audio from the Sub-comparators is br ought back to a Mast er comparator at the dispatch location. The Master comparator then picks the best signal from the subcomparators.

Figure 20 shows a way to monitor and control the comparators in a Zone or Master/Slave (Sub) Comparator system. Each of the remote sites has its comparators connected to CIB modules on its own MCN network. Each remote site is conne cted back to t he central (master ) site through a pa ir of EXB System Extender modules. The master site has its Master Comparator connected to CIB Comparator Interface Modules.

Since all the MCN networks are connected together at the master site, the PCs there can monitor comparators at multiple sites simultaneously. If, for instance, a wide-area channel has 3 subcomparators, the PCs can monitor all 3 sub-comparators and the master comparator simultaneously.

Appendix D Module Addressing and Receiver Banks

8. Appendix D Module Addressing and Receiver Banks

8.1 Module Addressing

Each MCN module is identified by a unique address that must be set at installation time. This address is specified by the combination of a Group number and a Module number. The Group and Module numbers are assigned with the rotary switches on either the front or back of the module. Whenever the Group or Module number is changed, the module must be reset or power cycled for the change to occur.

MODULEGROUP

CA-80046-100

Figure 22 - Group and Module Switches

Figure 22 shows a view of the Group and Module switches. Valid ranges of these switches are:

• Group number = 0 0 through FE

• Module number = 0 through F (16 module s per group)

Group number FF is reserved and should not be used for any module in the system. If Group number FF is assigned to a module, the module, when reset, will lock on its ERR LED and halt. All modules in a system must have unique addresses. If two or more modules are set to the same address, your system will not work properly and you could have unintended operation. Other than those restrictions, any Group/Module combination can be used for any module.

Certain MCN modules must have two addresses specified. One is for the MCN module that it will operate with and the other is for the module itself. The IIB module requires this dual address information. Refer to the IIB’s hardware reference manual for details about setting the two addresses.

Assign all Comparator I/O Modules to the same Group or set of Groups (if you have more than 16 modules), typically beginning with Group 00, Module 0 and progressing sequentially. Although modules can be added at higher addresses later, if you have plans to expand a channel, you may want to leave module addresses open for the expansion.

Assign all User Interface Modules to the same Group or set of Groups (if you have more than 16 modules), beginning with Group 80, Module 0.

When using the HIB User Interface Module with the MCN Remote Comparator Display software, only four Groups can be monitored and controlled at a time on one PC. If you are going to be using this User Interface Module, plan the addresses of your Comparator I/O modules so that you use as few different Groups as possible.

In a large system, you can monitor and control more than 4 Groups on a PC using the HIB; you are just limited to 4 groups simultaneously. For these types of large systems, group your modules so that all the receivers you may want to watch simultaneously are within the same 4 groups. Large systems (over 20 CIB and AIB modules) will be custom designed by CTI Products.

Page 44 MCN Comparator Display System Planner

8.2 Receiver Banks

The CIB parallel Comparator Interface Module controls and monitors 8 receivers. The AIB supports all 16 receivers of an ASTRO-TAC comparator.

For Comparator I/O Modules such as the AIB module that support more than 8 receivers, the receivers are grouped into MCN Remote Comparator Display software support only bank 0. Other User Interface Modules, such as the IIB, can be configured to control any one of the 8 banks.

Below is a list of the MCN banks and the receivers contained in those banks.

of 8 receivers. Some User Interface Modules, such as HIBs operating with the

banks

Table 8 - MCN Receiver Banks

In the example shown in Figure 23, the ASTRO-TAC comparator supports 16 receivers. The AIB divides the receivers into two banks (receiver banks 0 and 1) for its communications with the User Interface Modules (the IIB modules). Two IIBs are installed in the example system to support these 16 receivers. When the IIBs were installed, each had to b e configured (through front panel option switches) for the bank of receivers that each will be monitoring. The first IIB is configured to monitor receivers 1 through 8 (bank 0). The second IIB is configured to monitor receivers 9 through 16 ( bank

1). With this configuration, the consol e can monitor and control receivers 1 through 16 .

Appendix E System Limitations when using HIB and IIB Modules Together

9. Appendix E System Limitations when using HIB and IIB Modules Together

Because the console VOTE and DISABLE lines are bi-directional, the console’s LEDs will be lit if the console’s outputs are active. Because of this, the console could still indicate a DISABLE or VOTE on a receiver even if there is a problem in the network cabling or the Comparator I/O Module. Take for example the system shown in Figure 4.

When the DISABLE button on the console is pressed, the DISABLE LED on the console will immediately turn on and stay on after the DISABLE button is released since it is a latched output. The console will show a Disable condition, even if there was a problem with the network or the AIB.

Likewise, in a mixed system with HIBs and IIBs, if a receiver is disabled through the console (with its latching output) and then a PC user re-enables the receiver, the receiver will actually be enabled, but the console will show it as disabled. In this case, the console operator must press the disable button again to release the latch in the console.
