Introduction
The Wulfsberg C-5000 Communication Management Controller (CMC) is a microprocessor-based control
head device that controls one or two Wulfsberg transceivers. The C-5000 supports the full line of
Wulfsberg 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.
Features
The C-5000 provides a host of powerful features, including
Controls Wulfsberg RT-5000, RT-406F, RT-450, RT-138(F), RT-30, RT-118, RT-9600(F) and
RT-7200 transceivers.
700 preset channels, programmable from the front panel or using Wulfsberg’s Remote Programmer
software.
Users can dial in frequencies, PL tones, and transmit power on two “manual” channels.
Advanced multi-radio modes, such as Simulcast, Relay, Repeater, and Relay-Simulcast.
Control encryption functions embedded in the RT-5000 transceiver such as P25 Digital Modulation
and encryption with Over the Air Rekey (OTAR) capability.
Transceiver Overview
The C-5000 provides support for the Wulfsberg 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.
FLEXCOMM II
This product line consists of the RT-5000 AM/FM transceivers, which cover 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
DCS 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-rekey (OTAR)
capability.
FLEXCOM 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.
FLITECOMM
This product line is no longer manufactured, but remains in wide use. It consisted of the RT-7200, RT-
9600, and RT-9600F transceivers. They were available with a two-channel, crystal-controlled, Guard
Receiver that could be user-specified for any Guard frequency between 138.000 and 173.9950 MHz (RT-
7200) or between 150.000 and 173.9975 MHz (RT-9600/9600F). They were equipped with CTCSS tones
on both the Main and Guard Receivers.

Basic Operation
Front Panel & Controls
DISPLAY - The C-5000 has a 2 line display, with 20 characters on each line. It provides the visual
feedback for the system. Exactly what is displayed depends on the current operating mode of the C-
5000. During normal operation, the top line shows information for transceiver #1 and the bottom line
shows information for transceiver #2.
UPPER SOFT key – This key’s use depends on the current operating mode of the C-5000. Some
examples of its use are: increasing the display brightness and selecting radio 1’s guard receiver.
LOWER SOFT key - This key’s use depends on the current operating mode of the C-5000. Some
examples of its use are: decreasing the display brightness and selecting radio 2’s guard receiver.
OUTER VOLUME knob – This rotary switch is used to control the volume of radio 2.
INNER VOLUME knob – This rotary switch is used to control the volume of radio 1.
ON button – This button is used to turn the C-5000 on or off.
CURSOR knob – This rotary switch is used to move the cursor around the display.
VALUE knob – This rotary switch is used to modify values above the cursor.
ENTER button – This button’s use is dependent on the C-5000’s current operating mode, but is primarily
used to finalize data entry operations.
DATA TRANSFER PORT – This serial port is used to transfer data between the C-5000 and the
Wulfsberg Remote Programmer software. While preset channels can be programmed from the front
panel, the best method is to use a PC and the Wulfsberg Remote Programming (RP) software.
