  • Page 11: General Description

    Order Code..........................28 RT6512 ..........................28 Accessories ........................28 This manual describes the Becker Avionics remote-controlled VHF-AM transceiver RT6512-(XXX). The type plate on your device shows the part number for identification purposes (see "Type Plate", page 31). Before starting operation of the device(s) please read this manual carefully, with particular attention to the description referring to your device(s).

  • Page 12: Introduction

    Introduction The technical information in this document applies to the described product and variants of RT6512-(XXX). We use also the term RT6512 for descriptions instead writing the complete model number. • • If a description refers to only one of the product variants its full name is used.

  • Page 13: Purpose Of Equipment

    155.975 MHz and uses standard amplitude modulation (A3E). It can be operated by the Becker RCU6512 or RMU5000 using the RS422 control bus, or any OEM control device using the ARINC 429 control bus with standard label format.

  • Page 14: Scope Of Functionality

    It can receive a weak signal while a 2 VHF-AM transceiver in the same aircraft is transmitting. The RT6512 can operate with offset carrier in 25 kHz and 8.33 kHz channel spacing. • Transmit Mode The RT6512 has a high-quality Class 3 and 5 transmitters: The output power is 20 W under standard operating conditions (VSWR ≤...

  • Page 15: Audio Inputs And Outputs

    Figure 2: LINE_IN Schematic The RT6512 symmetrical line input has no DC connection to ground. Input impedance is 600 Ω. The maximum input level without clipping can be set as high as 6 V. The input audio signal is routed to a dynamic compressor keeping the modulation factor limited over a wide input voltage range.

  • Page 16: Audio Output Line Out

    1.5.5.1 /ON (Unit Power ON/OFF Control) /ON signal to set ON/OFF the RT6512. The /ON line is used to activate an internal electronic switch to power-up the device. It is active if the level on the /ON pin is less than 4.0 V or a resistance of less than 1 kΩ connects to ground.

  • Page 17: Rx_Att (External Rx Attenuation Control)

    /TX-ENABLE (Enabling the TX) /TX-ENABLE enables the transmitter. The RT6512 detects a low state on the /TX_ENABLE input when an external resistance lower than 1 kΩ connects to ground. The RT6512 detects a high state on the /TX_ENABLE input when an external resistance higher than 50 kΩ...

  • Page 18: Status And Control Outputs

    This /FAILURE output is coupled to the status shown at the status LEDs at the connector side of RT6512. It agrees to the OR function of the red and the yellow LEDs. When the test function is not ok, the transistor in the /FAILURE output is ON.
