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
