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-9600(F) and RT-7200 transceivers.
• 350 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 how many radios and what type are connected to the C-5000 since 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 covering 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
29.7 – 960 MHz receiver capable of being programmed with two Guard channels, or a receiver with one or two modules capable of RT-5000’s are equipped with CTCSS and DCS tones on both the Main and Guard Receivers. The MTM Guard variant of the RT-5000 adds support for P25 and Trunking channels, with encryption and over-the­air-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 RT­30, 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, crystal­controlled, 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.
C-5000 Operator’s Manual

Steps to Successful Setup and Operation

While we would like to pull products out of the box and immediately start to use them, this system is one that takes a little work to get to that point. The following checklist will help installers and initial users setup the C-5000 and RT-5000.
1. Connect C-5000 to the transceivers. Note part numbers of the Control head and all transceivers.
C-5000 Part Number = 31300-1X02- ____________
Radio #1 Model # = ___________________ Part Number = ______________________
Radio #2 Model # = ___________________ Part Number = ______________________
2. Configure the C-5000 using the steps outlined in the manual. You must know the last four digits of the C-5000
part number and the last four digits of any RT-5000’s or the model type of any Flexcomm/Flitecomm Transceiver.
3. If Radio #1 is an RT-5000 that has a MTM Guard Receiver (-06XX or greater) connect a PC to the 9-pin
programming port of the RT-5000 and run the Motorola RSS software.
4. Put the C-5000 in RSS mode for radio #1 and select the first ITM to appear.
5. Using the RSS software, read the codeplug out of the ITM.
6. Modify system settings for your application. Program personalities. Assign zone/Channels. These steps
require significant knowledge of the Motorola software. We encourage enlisting the help of someone familiar with Motorola RSS software to successfully program the ITM.
NOTE: ZONE 1 CHANNEL 1 MUST BE ASSIGNED TO A PERSONALITY THAT HAS DIFFERENT
RECEIVE AND TRANSMIT FREQUENCIES!!!!!
7. Save the modified codeplug to disk and load it into the ITM.
8. Make a listing of all ZONE/CHANNELS Information needed by the C-5000 preset channel programming.
Zone ______ Channel ______ RX Frequency = ______________________ RX Tone = __________ TX Frequency = ______________________ TX Tone = __________ Modulation = ______________(FM,P25,TRK)
9. Do the above for the second ITM if there is one in Radio #1
10. Do the above for Radio #2 only if its an RT-5000 with an MTM Guard (-06XX or greater)
11. Using the front panel or better yet the Wulfsberg RP software, program all preset channels including the ones
programmed into each ITM module in the steps above.
12. Using a communication analyzer or over the air test, verify that each radio and channel operates properly.

Changing Transmit Power

The C-5000 supports the selection of high and low transmit power. Normally high power is used, however, if interference or other transmit issues are experienced, low power may be selected to help remedy the issue. If you have a radio that supports multiple power levels, such as the RT-5000, you can alter the power setting from the EDIT PAGE as follows.
• Move the cursor under the transmit power field, as depicted below.

Enhanced System Features

Phone Patch Mode

The C-5000 can patch into the phone system using both DTMF and pulse dialing. This requires equipment on the ground, such as a transceiver and an interface box, to connect the base station radio to the telephone lines. This is NOT a cellular phone.
• From the HOME PAGE, select the radio and channel. Press the MENU button. The following display page
will appear.
DTMF SELECT PHONE PULSE DIALING MODE
• Press the UPPER SOFT KEY to select DTMF dialing, or the LOWER SOFT KEY to select pulse dialing. In
either case, the next display page will appear, and will look similar to the following. This example sho ws the dialing operation being performed on radio 1, channel 1.
