VCS 40C VHF COMMUNICATION SYSTEM
INSTALLATION MANUAL
SECTION 1 – GENERAL INFORMATION
1. Introduction
This section contains information relative to the physical, mechanical, and electrical
characteristics of the Wulfsberg VCS 40C VHF Communications System. This manual is
applicable only to VC-401C Transceiver and CD-402C Control Display.
2. Applicability
This manual applies to VC-401C Transceivers and CD-402C Control Displays.
3. Equipment Description
The Wulfsberg VCS 40C VHF Communications System is a fully synthesized ATC VHF
transceiver with TSO certification to TSO-37d and TSO 38d that provides a voice/data
communications link between the aircraft and ground facilities. The VCS 40C system consists of
a lightweight, remote-mounted VC-401C transceiver and a panel-mounted CD-402C Control
Display.
A. VC-401C VHF Communications Transceiver
The VC-401C VHF Communications Transceiver is available with fixed 8.33 kHz channel
spacing and switchable 25 kHz - 8.33 kHz channel spacing. Operation within the frequency
range of 118.00 – 136.975 MHz is standard. Extended operation within the frequency range
of 118.00 – 151.975 MHz is available as an option. These units are ICAO compliant.
The VC-401C is designed for rack mounting. The case is fitted with a handle on the front
panel for ease of handling during installation and removal.
The VC-401C consists of functional subassemblies interconnected via ribbon cables. The
subassemblies or circuit modules are hinged and attached to rigid, durable main frames
permitting easy access removal for service. Adjustments and test points are exposed and
available to the service technician without having to remove circuit module subassemblies or
use extender cables or cards.
Circuit modules are plug-in, enabling fault isolation through module substitution. A single
connector accepts all harness wiring on the rear of the VC-401C, while a BNC type RF
connector provides the VHF antenna connection through conventional coaxial cable.
B. CD-402C Control Display Unit
The CD-402C Control Display Unit is designed to be mounted in the instrument panel
individually, or combined in pairs in an adapter plate that will fit a standard DZUS mounting.
Front panel controls establish and display the operating status of all VC-401C functions.
Nonvolatile memory is used to retain the last frequency used, thus eliminating frequency
changes as a result of momentary or extended power disruptions.

Rev. H Section 1 – General Information
Mar 2007

VCS 40C VHF COMMUNICATION SYSTEM
INSTALLATION MANUAL
The system uses full-time self-test to monitor key internal circuits and to display the word
"FAIL" followed by a preassigned number to indicate which specific module has failed. Refer
to the Pilot’s Guide for FAIL message details.
The system is designed for compatibility with ARINC Characteristic 429 Digital Information
Transfer System to allow external frequency control of the VHF communications system. It is
also ACARS and Selcal compatible.
4. Available Configuration Variations
The following tables list the currently available configuration variations of the VC-401C and the
CD-402C.
