CCU Hardware Reference Introduction
CTI Products, Inc.
1. Introduction
The CCU Channel Control Units are used to control functions in a Land Mobile
Radio System such as:
Main / Standby Base
Repeat On/Off
Comparator A / Comparator B
Receive: Normal / Emergency Control Station (ECS)
Transmit: Normal / ECS
The CCU allows three independent consoles to control the above functions. It
allows each console to toggle the functions and provides feedback to the consoles
to indicate the state of each function. If one console fails, the others may continue
to control the system functions.
The CCU provides status indication of each function on the MCN (Monitoring
and Control Network), similar to a CIB module. It also allows the functions to be
toggled from a PC running the MCN Remote Comparator Display (MCNRCD)
software.
The CCU is a CIB Comparator Interface Module with special firmware.

CCU Hardware Reference Theory of Operation
CTI Products, Inc.
3. Theory of Operation
The CCU contains 5 similar toggle sections:
Main / Standby Base Select
Repeat On/Off
Comparator A / Comparator B Select
Receive: Normal / Emergency Control Station (ECS) Select
Transmit: Normal / ECS Select
Each section is essentially a Toggle Flip-Flop with multiple inputs and outputs.
Depending upon the Option Switch setting, the 5 sections can operate
independently, or there may be some interaction between sections.
There is a sixth section that provides a Force Select output for a TSAM unit.
3.1 Toggle Section Overview
Each of the toggle sections has (3) toggle inputs, (2) "Normal" outputs and (2)
"Inverted" outputs. Normal and inverted outputs are available to drive the console
inputs to allow flexibility in implementation. In most sections, one of the Inverted
outputs will be used as feedback to the console, since it is active in the "abnormal"
condition (Such as Standby, Repeat Disable, ECS, etc.).
Refer to Figure 3 – Main / Standby Base Section Logic for details of a typical
toggle section.
The Toggle inputs are active low. The Flip-Flop will toggle when either input
makes a high to low transition (after a debounce time).
The debounce is followed by a one-shot, and only the leading edge (high to low)
transition is seen from the console. Thus a stuck Toggle output from the console
will not prevent the other console from toggling the function in the CCU.
Outputs are active low. The Normal outputs are active on power-up
Typically, the #1 outputs drive the system control units and the #2 outputs provide
feedback to the consoles.
Status bits provide feedback to PCs on the MCN network. Depending upon the
Display Table used for the particular function, the state of the output(s) and / or
the input(s) can be seen.
Control bits provide input from PCs on the MCN network. Depending upon the
Display Table used for the particular function, the operator may either toggle the
function or explicitly Set or Reset the function.

Note that each output can drive only (1) RYB-8 relay. If you need to control
multiple relays (for TX Audio, Rx Audio & COR), you will have to use one relay
to buffer the coils for the other relays.
3.5 Section 4 – RX Normal / ECS Select
The Rx Normal / ECS Select section has a similar Toggle function as the
Main/Standby function.
There are three external inputs:
• /Rx Toggle 1 (from Console 1)
• /Rx Toggle 2 (from Console 2)
• /Rx Toggle 3 (from Console 3)
There are four logic outputs:
• /Rx Normal Select 1 (Normal)
• /Rx Normal Select 2 (Normal)
• /Rx ECS Select 1 (Inverted) To RX ECS Select Relay
• /Rx ECS Select 2 (Inverted) To Console Input

3.6 Section 5 – TX Normal / ECS Select
The Tx Normal / ECS Select section has a similar Toggle function as the
Main/Standby function.
There are three external inputs:
• /Tx Toggle 1 (from Console 1)
• /Tx Toggle 2 (from Console 2)
• /Tx Toggle 3 (from Console 3)
There are four logic outputs:
• /Tx Normal Select 1 (Normal)
• /Tx Normal Select 2 (Normal)
• /Tx ECS Select 1 (Inverted) To TX ECS Select Relay
• /Tx ECS Select 2 (Inverted) To Console Input
The TX ECS select can be used to disable the comparator repeat function. See
details in Section 2 - Repeater Control.
3.6.1 Slaved TX Select
The TX Normal / ECS Select section can be forced to be controlled by Section 4 Rx Normal / ECS Select as shown below:
Option

Rx Normal / ECS Section
Down
Independent Mode:
TX Normal / ECS Select
operates independently from the
Rx Normal / ECS Section
Table 3 – Slaved TX Select
If the Slaved mode is used, the Toggle inputs to the TX section are not connected.
3.7 Section 6 – TSAM Force Select Output
When one of the Toggle sections (typically the TX Main/Standby) is used to
control the TX Select (TXS1 & TXS2) inputs on the TSAM Transmitter Steering
Unit, the TSAM requires an additional Force Select input. Section 6 provides a
square wave output with a period of about 1 Hz. This ensures that the TSAM's
outputs will switch within 1 second of the output change in the CCU.
The Force Select output is not fed back to the MCNRCD network, since it would
only add a lot of unnecessary channel traffic.

7. Operation in an MCN Network
The CCU can be seen in an MCN network as a CIB unit or as a CCU unit. If the
MCNRCD software is configured to see it as a CIB unit, only the first 5 (toggle)
sections will be active as Function Blocks.
For each function block (section) of the CCU, you will have to select an
appropriate Display Table to use. Standard CCU Display Tables are:
Section Type Display Table Typical Display
1 Main/Standby Base CCU Base Main / Stby
2 Repeater On/.Off CCU Rptr On / Off
3 Comparator A/B CCU Comparator Comp A / Comp B
4 RX Norm/ECS CCU ECS Norm / ECS
5 TX Norm/ECS CCU ECS Norm / ECS
Table 10 – MCNRCD CCU Display Tables
Each of these Display Tables allow the user to toggle the function with the left or
right mouse function. These tables may be customized if desired. See the
MCNRCD Software Manual for details. The bit values for display and mouse
functions are shown below.

Mouse Toggle 1 Force Set Toggle 2 Force Reset
Bit
Table 11 –CCU Display Table & Mouse Bit Functions
The Toggle 1 In and Toggle 2 In reflect the state of the Tgl 1 & Tgl 2 inputs for
the particular section of the CCU being monitored. They will normally be "Don't
Care" bits in dispatch displays. They can be displayed (in a special bit-wise
display table) for use by a technician to verify that the Toggle signals from the
consoles are being seen at the CCU.
Normally the Toggle mouse actions will be used. The Force Set and Force Reset
functions are available to explicitly set and reset the functions. They are provided
to allow a special CCU device descriptor to be made for the MCNRCD software.
The Display Table entries for the CCU can be configured to generate logging or
alarms if desired.

8. Troubleshooting
This table is a list of troubleshooting tips specific to the CCU module. For
additional troubleshooting tips, refer to the troubleshooting section found in the
Monitoring and Control Network System Manual, reference 1.
Due to the high percentage of surface-mount components, the CCU is treated as a
field replaceable unit. If any system problems are the result of a malfunctioning
CCU unit, the entire unit must be replaced and returned for repair.
PROBLEM CAUSE
Signals do not toggle Verify that the appropriate inputs are going to ground. If you are
using relay contacts to drive the Toggle inputs, be sure the
common side of the relay contacts are grounded and connected to
Pin 1 of the CCU.
TX ECS doesn't change when
TX ECS Toggle inputs are
changed
Can't enable the Repeater
from the PC or with the Rpt
Toggle inputs.
TSAM not switching audio
outputs
Data from CCU changes,
when I/O lines are static
The ACT LED on the CCU is
off
You may have TX ECS slaved to RX ECS. Check Option
Switch 1.
You may have Force Repeat enabled. (Switches 2 & 3). If so,
when the Rx ECS Select or the TX ECS Select is active, you will
not be able to turn the Repeat On until the RX and/or TX ECS is
turned off.
Be sure that /TXS1, /TXS2, /Force Sel, and Ground are
connected to the TSAM and are acting properly..
You probably have multiple CCUs programmed for the same
Group/Module address. Reset the addresses and reset the
appropriate CCUs.
For instance, one CCU may have Comparator A selected and
another may have Comparator B selected. You will see the
indication change between Comp A & Comp B.
This is a normal condition if there is no PC accessing the CCU at
any given time.
