If antenna is installed on top of aircraft, drainage holes at smaller end of antenna should be
plugged with blanking plugs and RTV. Drainage holes in antenna base flange at mounting
face should not be obstructed.
If antenna is installed on underside of aircraft, drainage holes at smaller end of antenna base
flange at mounting face should be sealed with a small fillet of RTV.
The following section describes the wiring requirements and options for the installation of the
system. Because the system has so many features and options, it is recommended that the
installer take the time to read pin descriptions and all notes on wiring diagrams before designing
an installation.
Figure 4-1Rear View of C-5000
2.Wiring Considerations
To simplify the systems design, follow the steps below:
Step 1:Determine the type and number of radios. The C-5000 can control one or two
transceiver systems. The word system is used because a Flexcomm I installation can be
made of multiple transceivers electrically daisy chained to make one system. Based on the
type of radio, chose the part number of C-5000 that applies to your application.
Step 2:Determine the type of antenna. For each transceiver, determine the appropriate
antenna. For Flexcomm I transceivers, see the proper installation manuals for options. For
the RT-5000, the process begins by determining if the user needs optimum 30-88MHz
performance. If so, the recommended antenna system will be an “active” antenna (i.e. one
that is electrically tuned for maximum performance). If the user rarely uses 30-88 MHz, then
passive antenna is suggested. Passive antennas are less expensive and less complex to
install. Remember that performance in the 30-88 MHz frequency range is very degraded vs.
an active antenna.
Step 3:Microphone/Headset. If only one radio is installed, use the primary mic/headset
port. If two radios are installed, use primary mic/headset for transceiver system #1 and
secondary mic/headset for transceiver system #2. If only one mic/headset port is available
on the audio panel, use the primary mic/headset port and configure the C-5000 to operate in
“single mic mode”.
Step 4:Panel Lighting. Select the input pin on P500 for the desired backlighting.
Options are 28 Vdc (pin 30) or 5 Vdc/5vrms (pin 8).
Step 5:System Wiring. Based on steps 1-5, choose the wiring diagrams from this
section that apply to your configuration. Note that if you have two RT-5000’s in your system,
copy the wiring illustrated for P501 to P502. In other words, choose the wiring for each radio
and apply it to the appropriate connector.

(3)Primary Carbon Mic HI/LO (Pins 9, 29)
These pins provide a 150 Ohm input impedance for the crew microphone input. Standard
Carbon Mic bias of 15V through 300 Ohm s is provided. Standard modulation of 1 kHz
tone at 0.25 Vrms is factory set for ± 3 kHz deviation although an adjust range of 30 mV
to 1.5 Vrms is provided by A2R174 on the system interface board.
(4)Primary Mic PTT (Pin 18)
This pin, when grounded, activates the transceiver system(s) selected for the primary
mic/headset interface.
Note:The primary mic LO and PTT should be connected together at the mic interface
(audio panel or mic jack). Alternately, the mic LO should be grounded at the mic
interface as mic bias is not provided unless mic LO is DC grounded.
(5)Primary Headset Audio HI/COMMON (Pins 39, 40)
The pins provide receive and sidetone audio output for the transceiver system(s) selected
for the primary mic/headset interface. Standard audio levels of 100 mW into 600 Ohm
load is provided for standard modulation although an adjustment range of 0.5 to 200 mW
is provided by A2R86 of the system interface board.
(6)Secondary Carbon Mic HI/LO, Secondary PTT, and Secondary Headset Audio (Pins
10, 17, 20, 41)
These pins provide a similar interface as the primary counterparts with some functional
exceptions. Although levels and impedances provided are the same, the secondary
interface provides the limited function of talk and listen in clear, non-encrypted audio.
Features provided by the primary interface i.e. Selectable audio routing through internal
or external encryption systems integrated with the C-5000 are not supported at the
secondary interface.
(7)Shield (Pin 11)
All shields of signals originating at the C-5000 and terminating at other equipment should
be connected to this pin and left unterminated at the other equipment. Similarly, the
shields of signals originating at other equipment and terminating at the C-5000 should be
grounded at the other equipment and left unterminated at the C-5000.
(8)27.5 Vdc A/C Power and Ground (Pin 43, 44)
These pins provide aircraft 27.5 Vdc power to the C-5000 system. Typical loading is
approximately 350 mA, however with external loading by auxiliary equipment connected
to ±15 V and +5 V pins provided, the current requirement can be 1.3 Amp at 27.5 Vdc
and approach 2 Amps at low voltage. Appropriate circuit breaker should be provided with
consideration given to separately powered radio equipment as part of the basic
communications equipment being controlled b y the C-5000.

INSTALLATION MANUAL
(9)28V, 5V, Common Lites (Pins 8, 30, 50)
These pins provide for aircraft lite dimmer bus control of the keyboard lighting. Either
28 Vdc, 5 Vrms or 5 Vdc lighting may be used. The C-5000 does not draw power from
the buss but simply monitors the voltage for proper lite tracking. Only 5 V or 28 V may be
connected at once.
(10) RS-422 TX, RS-422 RX1, RS-422 RX2 HI/LO (Pins 2, 24, 25, 45, 46, 47)
These pins provide for a bi-directional digital data buss to other equipment on board the
aircraft. Two separate receive inputs are provided and the transmit pair may be
connected to multiple RS-422 devices. The receive shields should be connected only at
the originating equipment and the transmit shield should only be connected to the C-5000
shield pin.
(11) Internal Cipher Select A, B, C (Pins 5, 6, 55)
These pins are normally left unterminated and Internal Cipher Selection is managed from
the C-5000. Alternately, pins A, B, and C may be grounded in a binary fashion to provide
external selection of 1 of 7 internal cipher modes.
(12) Internal Cipher Disable (Pin 14)
This pin, when left unterminated, causes audio routing within the C-5000 to include the
Internal Cipher Interface. By grounding this pin, audio routing of the following signals is
to/from the external system interface for utilization with External Encryption Equipment,
auxiliary systems and functions generally used in conjunction with military equipment.
Associated signals routed to the External Interface are:
Mic output, voice band transmit audio input, wideband transmit audio input, wideband
receive audio output, voice band receiver audio output, decoded/de-encrypted voice
band received audio input, guard receiver voice band audio output.
This pin should normally be grounded unless an Internal Cipher module (or other special
module) is installed in the C-5000 and then it should be switched for Internal or External
routing of the "RT-X" signals.
(13) External Cipher Active (Pin 36)
This pin, when grounded, indicates to the C-5000 computer that external encryption
equipment connected to the system interface card is active and activated by external
control.
(14) XMT Audio IN HI/COMMON (Pins 3, 4)
This pair provides a voice band input to the transmitter(s) as selected by the crew.
Typical use is with external encryption equipment in which the mic input to the C-5000 is
routed out to the encryption unit and when the encryption unit is not active, the mic input
(voice band) is returned to this port for normal voice transmit. Standard levels are 0.9
Vrms into 600 Ω, although A2R160 and A2JP3 provide adjustment range of
approximately 40 mV (150 Ω) to 5.4 V (600Ω).
(15) Aux Audio IN HI (Pin 27)
This port provides an auxiliary input to the headset audio amplifiers (primary and
secondary). It is not switched and all inputs to this port will appear at the headset(s).
Typical use is alert tones, progress tones, medical telemetry equipment like Doppler
Monitors, etc. Typical input level of 0.5 Vrms (5k Ohm) will yield standard audio although
A2R102 on the system interface board provides an adjustment range of 0.33 to 7.75
Vrms.
(16) Plain/Cipher Select (Pin 35)
This output provides control signals to external equipment for activating encryption
equipment. For normal operation, this output is an open circuit. An active pull to ground is
provided for encryption active.
(17) Cipher/Plain Select (Pin 12)
This output is similar to Plain/Cipher, but is opposite polarity and provides a ground for
normal operation.
(18)Receiving External Encrypted Text (Pin 38)
This input, when grounded, indicates to the C-5000 computer that the external encryption
equipment at the system interface is receiving properly decoded and encrypted text.
(19) Transmitting External Encrypted Text (Pin 19)
When grounded, this input indicates to the C-5000 computer that the external encryption
equipment is active and is providing cipher text for wideband modulation to the crew
selected transmitter.
(20) PTT To Cipher (Pin 56)
This pin provides a ground to repeat the mic input (primary only).
(21) PTT From External Cipher (Pin 15)
When grounded, this pin will cause the C-5000 to remain in transmit mode. Transmitter
end of text messages can be transmitted after mic PTT has been released by utilizing this
input as a stretched or delayed PTT input.
(22) Zeroize (Pin 26)
This pin provides an output from the C-5000 to external encryption (internal as well)
equipment to erase key variables. This output is configured as standard to provide an
open circuit under normal operation and provide 27.5 Vdc to Zeroize key variables in
encryption equipment. By changing A2JP8 on the system interface board from "l to 2" to
"2 to 3", the output provides an active ground for Zeroizing (open circuit = normal).

(23) Mic Out HI/LO (Pins 48, 49)
This pair provides a buffered primary mic output. As standard configuration, the balanced
mic output is a combination of Primary Mic Input, REXMT Audio In, XMT Audio In and
Internal Cipher Voice XMT Audio. The level is set for 0.25 Vrms for standard modulation.
When external (or internal) encryption equipment is connected to the system interface
board, A2JP2 on the system interface board is typically moved from "l to 2" to "2 to 3"
and zero Ohm resistor A2R140 (system interface board) is removed. With A2JP2
changed and A2R140 removed, the mic out is only the buffered primary mic input. In
addition, the primary mic input is isolated from the rest of the C-5000 such that normal
clear text voice modulation must be routed from mic out Hi/Lo. In this configuration, the
external encryption equipment must be installed to complete the audio path from the
primary mic input to the selected transmitter(s). Jumpers from mic out Hi/Lo to XMT
Audio In Hi/Lo may be used temporarily when the external encryption equipment is
disconnected. Audio levels are typically 0.9 Vrms (600 Ω) although A2R170 on the
system interface board provides considerable adjustment range.
(24) Guard Precedence In or System Precedence Channel Select (Pin 22)
This pin, when grounded, disables nearly all of the C-5000 functions and channels the
system to a pre-stored precedence channel. The volume control is functional. This mode
is useful for an emergency mode in which all functions are disabled except basic
talk/listen on the pre-stored system precedence channel. Normal operation is with this pin
open circuited.
(25) Bandwidth Control In (Pin 23)
This pin, when grounded, activates the wideband mode on new WED radio equipment.
Normal mode is open circuit.
(26) RT-X Select A & B (Pins 16,33)
These pins, when grounded, provide and external selection (in binary format) of the
selected radio system 1, 2 or 3 to be routed to the internal or external system interface for
encryption or other functions connected to the system interface. Normal mode with
C-5000 selection of the RT-X (1, 2 or 3) system is provided when these lines are open
circuit.

(27) RT-X Guard Audio Out (Pin 13)
This pin provides the selected RT System Guard RCV Audio (voice band) signal for use
with external equipment. Typically the plain text guard audio is summed with decoded
main RCV audio and routed to the C-5000 for combined main (recovered cipher) and
guard (clear) to the headset. Standard levels are 2 Vrms at low impedance, although
A2R114 on the system interface board provides adjustment range of 0.5 to 4 Vrms.
(28) REXMT Audio In (Pin 7)
This input provides an auxiliary voice band transmit audio input and is summed with the
primary mic audio. The receive audio from other equipment can be routed to this port and
in conjunction with the "PTT from Ext. Cipher" (an auxiliary PTT input), a multi-system
relay can be established. A level of 2 Vrms for standard modulation is standard, although
A2R167 on the system interface board provides an adjustment range of 0.1 to 7.75 Vrms.
(29) RT-X REXMT Audio Out (Pin 1)
This pin provides a voice band receive audio output from the selected RT system (1, 2 or
3). The audio is normal audio from the selected radio system and includes both main and
guard audio as well as sidetone during XMT. In conjunction with REXMT control key out,
(squelch activity from this system and PTT input to other aircraft equipment) this signal
may be used in a multi system relay to provide receive audio from this system to transmit
audio to other equipment on board the aircraft.
Typical application with external encryption equipment connected to the system interface
utilizes this signal as clear text receive audio to be routed to, and returned from, the
external equipment in time of nonencrypted reception to the RT-X Decoded Audio Input.
The signal level is 2 Vrms for standard voice, although A2R108 on the system board
provides an adjustment range of 0.2 to 7.75 Vrms.
(30) RT-X REXMT Control Key Out (Pin 34)
This signal provides a ground output when the selected radio system (1, 2 or 3) main
receiver is active (squelch activity). This signal provides a PTT input to other aircraft
equipment in a multi-system relay mode.
(31) RT-X WB MN RCV Audio Out (Pin 37)
This signal is a wideband received audio signal from the selected RT system (1, 2 or 3)
main receiver. It is not squelch gated and typically is used with external encryption
equipment connected to the system interface. The standard level is 6 Vpp although
A2R135 provides an adjustment range of 1.2 to 12 Vpp. The Motorola encryption
equipment requires 4 Vpp.
(32) EXT RT-X Decoded RCV Audio (Pin 42)
This input is typically used with external encryption equipment connected to the system
interface. The signal is the decoded or de-encrypted voice band clear text from the
encryption system. By proper C-5000 system programming, this signal can be routed
directly as the selected RT system (1, 2 or 3) recovered audio or it can be internally
summed with the selected RT system guard audio, sidetone, or both. In addition, the
recovered audio can also be programmed to provide de-emphasis if required. A level of 2
Vrms is standard, although A2R131 provides an adjustment range of 0.25 to 7.75 Vrms.

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
• 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.
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.

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 lo ad 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.
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 displa y.
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.
