Section I GENERAL DESCRIPTION1.1 IntroductionThis manual describes the VHF transceiver AR6201-(XXX). The manuals DV 14300.03 (“Installationand Operation”) and DV 14300.04 (“Maintenance and Repair”) contain the following sections.Section DV 14300.03 DV 14300.041General Information XX2Installation XX3Operation XX4Theory of operation N/A X5Maintenance and Repair N/A X6Illustrated Parts List N/A X7Modification and Changes N/A X8Circuit Diagrams N/A x1.2 Purpose of equipmentThe VHF transceiver enables voice communication in the very high frequency band between118.000 MHz to 136.990 MHz (radio communication part of airband) with a channel spacing of 25 kHzin 25 kHz mode and with 8.333 kHz channel spacing in 25+8.33 kHz mixed mode.1.3 General descriptionThe VHF transceiver is designed without any verified environmental class restrictions. It can be fittedin the instrument panel of all aircraft types.The VHF transceiver can be fully remote controlled via a RS422 interface and the industry establishedCommercial Serial Data Bus protocol.DV 14300.03/04 Issue 1 05/10 Page 1-1AR6201
Configuration of the system is possible by means of a dedicated service interface implemented as aRS422 interface line with a proprietary serial data communication protocol.The VHF transceiver is a compact and lightweight single block unit. The dimensions correspond to thestandard instrument diameter of 58 mm (2 1/4 inch). Mounting is by means of four screws (rear panelmounting). All controls and indicators are located on the front panel. The equipment connectors andthe antenna socket are located at the rear of the unit.After switch on, the unit performs a self test (PBIT). After the PBIT the transceiver shows “WAIT” andthe corresponding software versions of the control head and chassis module. If the PBIT detects a fatalerror, the transceiver terminates operation and will be locked.The transmitter is designed for the 118.000 MHz to 137.000 MHz frequency range. The sidetone isavailable on the headphone output during transmission. The sidetone level can be set in the servicemenu.The frequency indication is by means of a liquid crystal display (LCD). The required operating frequen-cy is set with the frequency selector switch. The pushbutton selects the digits.Memory channelsThe VHF transceiver also contains a memory device for storing 99 different frequencies which remainstored even with the unit switched off without an auxiliary battery. Last 9 frequencies are stored auto-matically.Mike inputsThe VHF transceiver has an input for dynamic microphone (DYN_MIKE) and an input for standard mi-crophone (STD_MIKE). Each input is able to operate with single microphone or with 2 microphones ofthe same type connected in parallel.AF auxiliary inputThe AF auxiliary input enables AF signal switching of auxiliary units in the aircraft. The switched AF sig-nals can be monitored in the reception mode only .Audio outputsThe Headphone rated output power is ³300 mW @ 150 Ohm.The transceiver includes a speaker output (SPK). The rated output power from the Speaker Output ismin.4W@4OhmThe transceiver has an asymmetrical LINE output (LINE_OUT). When the transceiver is operating inRX mode the line output supplies the sum of intercom audio, receiver audio and auxiliary audio.Whenthe transceiver is operating in TX mode, then the LINE output supplies the natural sidetone.Intercom modeAircraft internal communication is possible in the intercom mode (IC). The intercom mode is activatedby a long press of the SQL/IC button.Squelch OperationThere are two kinds of squelch methods implemented. The carrier squelch (C_Squelch) and noisesquelch (N_Squelch). The carrier squelch is based on received signal strength; the noise squelch isbased on noise level detected in demodulated received signal.Page 1-2 DV 14300.03/04 Issue 1 05/10AR6201
Scan sub modeThe scan sub-mode is activated by a long press of the EXCHANGE/SCAN key in all selection modes.IlluminationThe VHF transceiver include a dimming input that controls illumination of LCD and push buttons. Thedimming entry is either 14V AC/DC or 28V DC.The illumination can be dimmed from off to full illumination.The display has minimum illumination to en-sure that the indicators are always visible.The characteristic of the dimming and illumination curve can be adapted to other units in the instrumentpanel in the service mode. The unit setup enables selection value of display contrast in range of 0 …100 %.Monitoring stage for the power supply voltageThe VHF transceiver also contains a monitoring stage for the power supply voltage which is activatedwhen the VHF transceiver is switched on. If the supply voltage drops below 10.5 V (Low BatteryThreshold), the display indicates the message “LOW BATT”.Emergency operationIn emergency operation the following performance reduction is possible i.e. when the supply voltagedropped down to 9 V.pFor TX Mode: RF Rated power is ³2W@50Ohm, modulation depth is ³50 %,pFor RX Mode: (S+N)/N ³6 dB for RF level -93 dBm, m = 30% 1 kHz sine1.4 Variants surveyType designationPart-No.:Nominal supplyvoltageTransmitteroutputPanel lighting Panel colourVHF Transceiver single blockGreen AR6201-(000)Article Nr.: 0610.321-91013.75 V ³6W 13.75 V /27.5 VblackVHF Transceiver single block-Blue-White AR6201-(002)Article Nr.: 0614.203-91013.75 V ³6W 13.75 V /27.5 VblackDV 14300.03/04 Issue 1 05/10 Page 1-3AR6201
