SECTION 1 – GENERAL INFORMATION
1. Introduction
This section contains information relative to the physical, mechanical, and electrical
characteristics of the Wulfsberg Electronics “2000” Family of Communications Systems.
2. Applicability
This manual applies only to the P-2000 panel mount transceiver, C-2000 control unit, and RT-
2000 remote mount transceiver.
3. Equipment Description
The Wulfsberg “2000” family FM Communications System is a dual transceiver FM voice
communications link between the aircraft and ground facilities. The system has not been
designed by the manufacturer to be installed on Type Certificated aircraft. Installations on these
type of aircraft are subject to applicable FAA regulations.
The “2000” family consists of the P-2000 panel mount transceiver and C-2000/RT-2000 control
and remote mount transceiver.
A. P-2000 Panel Mount FM Communications Transceiver
The Wulfsberg P-2000 is a FM Tactical transceiver that incorporates one or two transceiver
modules and control functions into a single panel mount unit. Part number variations of the
unit exist for any combination of the following frequency bands: 138-174 MHz, 403-470 MHz,
450-520 MHz, and 806-870 MHz. Each transceiver module with the exception of the 806-870
MHz band can transmit with 1 or 10 Watts transmit power. The 800 MHz unit produces 1 and
3 watts transmit power. The P-2000 can operate by itself or in conjunction with the C-2000
control display acting as a remote slave control. Input voltage is 28 volts DC and the keypad
is backlit from either 28VDC, 5 VDC or 5 VRMS AC.
The P-2000 transceiver is designed to be mounted in the instrument panel that will fit a
standard DZUS mounting. Two connectors, a DB-25 and DB-15 accept all harness wiring on
the rear of the P-2000, while two TNC type RF connector provides the antenna connection
through conventional coaxial cables. For models containing one transceiver, only one
antenna port is provided.
The P-2000 consists of functional subassemblies interconnected via standard connectors and
ribbon cables. The case of the P-2000 is designed to be disassembled easily to expose most
subassemblies or circuit modules for service. All adjustments to audio levels can be made
via software and do not require the disassembly of the box. Internal test points are exposed
and available to the service technician without having to remove circuit module
subassemblies or use extender cables or cards.
The P-2000 is designed to be drop-in replacement for the C-962A/S Control unit for the
Wulfsberg RT-9600/7200 transceiver systems also known as the ARC-513 with the exception
of the 28 Volt input power. Due to increased 28 power requirements of the P-2000, wire size

on this input may need to be increased to 20 AWG. All other microphone inputs/headset
outputs and backliting are compatible.
B. C-2000 Control Display Unit
The Wulfsberg C-2000 is a control display unit that can be used as a slave control head with
a P-2000 panel mount transceiver, or as a primary or slave control head for the RT- 2000
remote transceiver. Versions of the C-2000 include black faceplate and options for either
Standard or NVG compatible displays. Input voltage is 28 volts DC and the keypad is backlit
from either 28 VDC, 5 VDC or 5 VRMS.
The C-2000 Control Display Unit is designed to be mounted in the instrument panel that will
fit a standard DZUS mounting. Two connectors, a DB-25 and DB-15, accept all harness
wiring on the rear of the P-2000.
Front panel controls establish and display the operating status of all RT-2000 or P-2000
functions when operating as a slave control unit.
C. RT-2000 Remote Mount FM Communications Transceiver
The Wulfsberg RT-2000 is a FM Tactical transceiver that incorporates one or two transceiver
modules and control functions into a single panel mount unit. Part number variations of the
unit exist for any combination of the following frequency bands: 138-174 MHz, 403-470 MHz,
450-520 MHz, and 806-870 MHz. Each transceiver module with the exception of the 806-870
MHz band can transmit with 1 or 10 Watts transmit power. The 800 MHz unit produces 1 and
3 watts transmit power. The RT-2000 is designed to be controlled by a C-2000 control
display. Input voltage is 28 volts DC and the keypad is backlit from either 28VDC, 5 VDC or
5 VRMS AC.
The RT-2000 transceiver is designed to be mounted rack mounted. Two connectors, a DB-
25 and DB-15 accept all harness wiring on the rear of the RT-2000, while two TNC type RF
connector provides the antenna connection through conventional coaxial cables. For models
containing one transceiver, only one antenna port is provided.
The RT-2000 consists of functional subassemblies interconnected via standard connectors
and ribbon cables. The case of the RT-2000 is designed to be easily disassembled to expose
most subassemblies or circuit modules for service. All adjustments to audio levels can be
made via software and do not require the disassembly of the box. Internal test points are
exposed and available to the service technician without having to remove circuit module
subassemblies or use extender cables or cards.
The RT-2000 is designed to fit into a rack space equivalent with the Wulfsberg RT-9600 with
exception of depth. The RT-2000 is only approximately 7 inches deep vs. the nearly 14 inch
depth of the RT-9600.
Multiple C-2000’s can be used for multi-point control of the RT-2000.

2000/RT-2000. Close adherence to these suggestions will assure a more satisfactory
performance from the equipment.
2. Unpacking and Inspecting Equipment
Exercise extreme care when unpacking the equipment. Make a visual inspection of the units for
evidence of damage incurred during shipment. If a claim for damage is to be made, save the
shipping container to substantiate the claim. The claim should be promptly filed with the
transportation company. It would be advisable to retain the container and packaging material after
all equipment has been removed in the event that equipment storage or reshipment should
become necessary.
3. Equipment Installation
The P-2000/C-2000/RT-2000 installations will conform to standards designated by the customer,
installing agency, and existing conditions as to the unit location and type of installation. See
Figures 2-1 through 2-7 for an outline drawings of the LRU’s, installation tray, and antennas.
Before beginning installation the installing agency should review the drawings, electrical
interwiring diagram and installation pictorials which are located in this section, and establish
requirements to a particular aircraft.
A. Cooling Considerations
The greatest single contributor to increased reliability of all modern day avionics is limiting the
maximum operating temperature of the individual units, whether panel-mounted or remote-
mounted. While modern day circuit designs consume far less electrical energy, the watts per
cubic inch dissipated within the avionics units still remains much the same due to high density
packaging techniques utilized. Consequently, the importance of providing avionics cooling is
essential to the life span of the unit.
The combined heat load of several units operating in a typical avionics location will
significantly degrade the reliability of the avionics if provisions for cooling are not incorporated
in the initial installation. Failure to provide cooling will certainly lead to increased avionics
maintenance costs and may void the Wulfsberg warranty.
B. P-2000 Mechanical Installation
(1) Select the P-2000 mounting location. Insure that unit will be easily accessible and
clearly visible to the operator. The location should be free from excessive moisture,
vibration, heat and noise generating sources. The unit has standard Dzus mount
dimensions as shown in Figure 2-1. Allow adequate space and service loops for
installation of cables and connectors.

(2) The installing agency will supply and fabricate all external cables. The connectors
are supplied separately and are listed in Section 1.F.
(3) The length and routing of the external cables must be carefrully studied and planned
before attempting actual installation. Avoid sharp bends and placing cables too
near other aircraft cables.
(4) Use only recommended wire sizes and wire type for interwiring. Wire sizes and wire
type are listed on the interwiring diagrams.
C. C-2000 Mechanical Installation
(1) Select the P-2000 mounting location. Insure that unit will be easily accessible and
clearly visible to the operator. The location should be free from excessive moisture,
vibration, heat and noise generating sources. The unit has standard Dzus mount
dimensions as shown in Figure 2-1. Allow adequate space and service loops for
installation of cables and connectors.

D. RT-2000 Mechanical Installation
(1) Select the RT-2000 mounting location. The location should be free from excessive
moisture, vibration, heat and noise generating sources. The unit can be rigidly
mounted. Allow at least one inch of free air space around the top and rear of the unit
and one-half inch along each side. Allow adequate space for installation of cables
and connectors.
(2) Refer to Figure 2-3 for the RT-2000 mounting dimensions.
(3) Mark, punch, and drill the mounting holes. Care must be taken to avoid damage to
adjacent equipment or cables.
(4) Secure the mounting tray firmly in place.
(5) Secure the RT-2000 to the mounting tray and connect all appropriate connectors
taking care to apply the correct RF connector to the desired transceiver.

E. Antenna Mechanical Installation
(1) Antenna installation is critical to the range and quality of the transmitted signal.
Care should be taken to keep all antennas a separated as possible. A minimum of
70 cm should be observed if possible.
(2) Whenever possible, mount antennas on the bottom of the aircraft. The only
exception is if two antennas covering the same frequency band are used, put one
on the top of the aircraft and the other on the bottom to achieve maximum isolation.
If this is not possible, put on the front of the aircraft and one on the rear.
(3) The antennas should be mounted on a flat metal surface to obtain a proper ground
plane. Ensure the antenna is adequately grounded to the aircraft skin (<5 mohm is
a standard rule of thumb).
(4) P-2000/RT-2000 antennas should be mounted a minimum of 20 cm from each
other.
(5) Wulfsberg recommends the use of RG-193 on most installations. Installers can
substitute other types of coax than RG-193 to get better performance especially at
higher frequencies. Be aware that each type of coaxial cable requires specific
connectors that may only be available from the coaxial cable manufacturer.
