Operator’s Manual
3. Introduction
The Cobham C-5000 Communication Management Controller (CMC) is a microprocessor-based control
head device that controls one or two Cobham transceivers. The C-5000 supports the full line of Cobham
FLITECOMM, FLEXCOMM I, and FLEXCOMM II transceivers. This manual is intended to quickly instruct
the user on the basic operations of the C-5000 and also outline the advanced operations that set the C-
5000 apart from any other communication device.
A. Features
The C-5000 provides a host of powerful features, including
(1) Controls Cobham RT-5000, RT-406F, RT-450, RT-138(F), RT-30, RT-9600(F) and RT-
7200 transceivers.
(2) 700 preset channels, programmable from the front panel or using Cobham’s Remote
Programmer software.
Note:
Software versions 10 and below are only capable of 350 preset channels.
(3) Users can dial in frequencies, PL tones, and transmit power on two “manual” channels.
Note:
One manual channel available per RT system.
(4) Advanced multi-radio modes, such as Simulcast, Relay, Repeater, and Relay-Simulcast.
(5) Control encryption functions embedded in the RT-5000 transceiver such as APCO P25
compliant digital voice and encryption with Over the Air Re-key (OTAR) capability.
Note:
Applicable to units with Motorola ITMs installed (-06xx or greater).
B. Transceiver Overview
The C-50
00 provides support for the Cobham FLITECOMM, FLEXCOMM I, and FLEXCOMM II
transceivers. It is very important that users know the number and type of transceivers connected to
the C-5000, since different transceivers have very different capabilities and features. Here is a
summary of the supported transceivers and their capabilities:
1. FLEXCOMM II
This product line consists of the RT-5000 AM/FM transceiver, which covers the 29.7 to 960 MHz
frequency range. The optional Guard Receiver can be specified as a single channel crystal guard
(available in three frequency ranges), a tunable multi-channel guard (29.7 – 960 MHz), or a multi-
band digital-capable guard (available in four frequency ranges). RT-5000’s are equipped with
CTCSS and CS tones on both the Main and Guard Receivers. The MTM (digital-capable) Guard
variant of the RT-5000 adds support for P25 and Trunking channels, with encryption and over-the-air-
re-key (OTAR) capability.
2. FLEXCOMM I
This product line currently consists of the RT-30, RT-138F, and RT-406F transceivers. The C-5000
also supports the RT-118, RT-138, and RT-450 transceivers, which are no longer manufactured but
remain in wide use. The RT-30, RT-138F, and RT-406F FM transceivers cover the 29.7 to 49.99
MHz, 138.0 to 173.9975 MHz, and 406.0 to 511.9975 MHz frequency ranges, respectively. These
transceivers can be specified with a single-channel, crystal-controlled, Guard Receiver that operates
on a customer specified frequency. An optional Guard Receiver CTCSS decoder with programmable
Guard Receiver tone can also be specified.
