Purpose of Equipment • The remote-controlled VHF-AM transceiver is a half-duplex voice communication system in the standard avionics VHF frequency range 118.000...136.975 MHz (136.9916 MHz with 8.33 kHz channel spacing), or optional with extended frequency range up to 155.975 MHz and uses standard amplitude modulation (A3E). The VHF-AM transceiver is capable to operate in both, the 25 or 8.33 kHz channel spacing, is primarily intended for aeronautical operational control (AOC) and air traffic services (ATS) safety communications. • The RT6512 remote controlled VHF-AM transceiver uses ARINC 429 and RS422 interfaces for communication with a control device. • RT6512 provides frequency and mode control, either by means of the Becker RCU6512 (certification is pending) or RMU5000 controller using the RS422 communication port, or by means of any OEM product using the standard ARINC 429 communication bus. • With transmitter power at least 16 W under all environmental conditions RT6512 is able to support simultaneous communication over a range exceeding 200 NM direct line of sight, within the frequency range. Variants Overview Within the part number, the meaning of "RT6512-(XXX)", is: RT 6512 - ( X X X ) 0 - Standard Type Identifier Model Number 0 - Standard 1 – Std. Freq. Range 118...136.975 MHz 2 – Ext. Freq. Range 118...155.975 MHz 1.4. General Description The VHF-AM transceiver performs AM voice communication then contains modules: RX, TX, Audio, digital communication. Mechanics: Case serves as heat sink, mount it proper as defined in chapter Mechanical Installation, page 27. Front side contains the main connector (D-Sub 37pin, male) for connection to the aircraft wiring system, and the antenna jack (BNC, female). The green LED indicates the system is operable. The yellow and red LED indicates that a warning or failure has occurred (refer to Status & Error Indication, page 40). 1.4.1. Receive Mode The VHF-AM transceiver is equipped with a high quality Class C, E and H2 receiver: standard sensitivity 5 µV, high dynamic range, high blocking rejection. It can receive a weak signal while a 2nd VHF-AM transceiver in the same aircraft is transmitting. The RT6512 VHF-AM transceiver can operate with offset carrier in both 25 kHz and 8.33 kHz cannel spacing. 10 RT6512 DV17501.03 Issue 01 June 2015 Device Description General Description 1.4.2. Transmit Mode The VHF-AM transceiver is equipped with a high quality Class 3 and 5 transmitter: output power of 20 W under standard operating conditions, output power of at least 16 W under the specified environmental operating conditions (when using antenna with VSWR=1, for VSWR>1 output power lowers), AM depth >70% - standard value for airborne application. During transmission, the transmitter delivers a natural sidetone signal, which is available on the LINE_OUT output (if enabled). The VHF-AM transceiver is equipped with a protective function to prevent from blocking the frequency channel by a stucked transmit button or a short circuit on the key line. "Stuck PTT" time limit setting can be set by factory between 30 seconds and 3 minutes. Default setting for Stuck PTT time is 35 seconds. RT6512 transmitter is protected from overheating. VSWR on Antenna connector is also monitored. See chapter Status and Control Outputs, page 13 for details. 1.4.3. Audio Inputs and Outputs 1.4.3.1. Microphone Input Figure 1 Standard Microphone Input schematic The VHF-AM transceiver is designed for a standard microphone: unbalanced, DC coupled, DC supplied from VHF-AM transceiver. The bias current for standard microphone is drawn from VHF-AM transceivers internal source 15 VDC via series resistor 470 Ohm. The input audio signal is routed to a dynamic compressor keeping the modulation factor limited over a wide input voltage range. The microphone input uses the cable guard as ground compensation so microphone input shall be connected exactly as specified on Installation diagrams. 1.4.3.2. Audio Input LINE IN Figure 2 LINE_IN schematic The VHF-AM transceivers 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. DV17501.03 Issue 01 June 2015 RT6512 11 Device Description General Description 1.4.3.3. Audio Output LINE OUT Figure 3 LINE_OUT The audio output LINE OUT design is symmetrical and has no DC connection to ground. If volume set to maximum, the audio output power delivered is 100…125 mW into 600 Ω or 200 mW into 150 Ω. 1.4.4. Control In-and Outputs 1.4.4.1. /ON line (Unit Power ON/OFF Control) The /ON line is used to activate an internal electronic switch to Power-Up the unit. It is active if the level on the /ON pin is less than 4.0 V or a resistance of less than 1000 Ω connects to ground. The /ON line is inactive if the level on the /ON pin is higher than 8.0 V or a resistance higher than 50 kΩ connects to ground. 1.4.4.2. /PTT line (Press-To-Talk Input) The /PTT line is used to initiate transmission. It is active when /PTT-input level is below 4.0 V, or a resistance to ground of less than 1000 Ω. The /PTT line is inactive if the level on the /PTT-input is higher than 8.0 V, or a resistance higher than 50 kΩ connects to ground. 1.4.4.3. /RX_ATT (External RX Attenuation Control) The /RX_ATT line is used for an optional desensitization of the RT6512 receiver. The desensitization can be required when a 2nd VHF-AM transceiver in the same aircraft is transmitting. In such case /PTT line from 1st VHF-AM transceiver shall be connected to /RX_ATT input of 2nd device and /PTT from 2nd device shall be connected to /RX_ATT input of the 1st device. The /RX_ATT is active if /RX_ATT-input level is less than 4.0 V, or a resistance less than 1000 Ω connects to ground. The /RX_ATT line is inactive if the level on the /RX_ATT-input is higher than 8.0 V, or a resistance higher than 50 kΩ connects to ground. 1.4.4.4. /TX-ENABLE (Enabling the TX) The VHF-AM transceiver detects a low state on the /TX_ENABLE input when an external resistance lower than 1000 Ω connects to ground. The VHF-AM transceiver is detecting high state on the /TX_ENABLE input when an external resistance higher than 50 kΩ connects to ground. In such case transmission is permanently blocked. For an aircraft installation /TX-ENABLE input shall be connected to ground directly on the main connector. /TX-ENABLE line cannot be routed as part of installation cable bundle. Note: Do not apply DC voltage above 5 Volts to /TX_ENABLE to avoid device damage! 12 RT6512 DV17501.03 Issue 01 June 2015 Device Description General Description 1.4.5. Status and Control Outputs 1.4.5.1. /FAILURE Figure 4 /FAILURE output schematic This /FAILURE output is coupled to the status shown at the status LEDs mounted at the connector side of the VHF-AM transceiver. It corresponds to OR function of the red and the yellow LEDs. When the test function is not ok, the transistor in the /FAILURE output is ON. This output is an open collector (drain) type with capability to: • Draw maximum 100 mA current to ground with a voltage drop of less than 2.5 V (corresponding LEDs is on), • Draw maximum 0.1 mA current to ground for output voltage 28.0 V when in "inactive" state (corresponding LEDs are off). It can be used to drive an external relay if 100 mA output current limit at the supply voltage 28.0 V is not sufficient. This /FAILURE output is protected against spikes produced from a relay. See Status & Error Indication, page 40. 1.4.5.2. /SQL_EVAL This digital output indicates that the audio signal from the receiver is available on the LINE_OUT. This output is an open collector type (the same schematic as for /FAILURE output) with capability to: This output is an open collector type with capability to: • Draw maximum 100 mA current to ground with a voltage drop of less than 2.5 V (corresponding LED(s) is on), • Draw maximum 0.1 mA current to ground for output voltage 28.0 V when in "inactive" state (corresponding LEDs are off).

ARINC 429 Protocol supported by RT6512 ...................................................................... 42 Device Description The RT6512 is designed to be operated by means of an remote control device which could either be the Becker RCU6512, Becker RMU5000 using the RS422 control bus, or any OEM control device using the ARINC 429 control bus with standard label format. 3.1.1. Device Assignment This manual is valid for the following devices: See page 26 3.2. Start-Up Excessive pulses on the DC bus of the aircraft may cause damage on electrical circuits of any installed instrument. Do not switch ON the device during engine start or shutdown. 3.2.1. Built In Tests (BIT) The RT6512 has advanced Built-In-Test. It monitors most of internal circuits against failures. In addition BIT monitors some external (installation) conditions to increase VHF-AM transceiver’s reliability. There are three types of BIT implemented: PBIT (performed after Power ON the unit), IBIT (initiated by special command via serial protocol) and CBIT (which continuously check VHF-AM transceiver operation). DV17501.03 Issue 01 June 2015 RT6512 37 Operating Instructions Start-Up The following functions are checked under BIT: • Power Supply (PSB Error) BIT function monitors internal Power Supply conditions. “PSB error” is classified as an "internal failure". • RCU Lost Connection Error If the VHF-AM transceiver does not receive any valid frame via the RS422 serial interface within each 5 seconds, then the “RCU Lost Connection Error” appears and classifies as “external failure”. If RT6512 is controlled by ARINC 429 interface, detecting “RCU Lost Connection Error” is blocked. • Channel Error If the VHF-AM transceiver receives an invalid channel name, then the "Channel Error" appears and classifies as ”external failure”. • RX Synthesizer Error The VHF-AM transceiver monitors the RX synthesizer(s). If any error behavior is detected, the “RX Synthesizer Error” indication appears and is classified as an internal failure. • RX AGC Error AGC voltage of the RX (RF-AGC) is monitored. If an error behavior is detected, the device indicate a "RX AGC Error" • TX Output Power Error In TX mode, the VHF-AM transceiver is monitoring the forward power at the antenna connector. If any error behavior is detected a “TX Output Power Error” indication appears and is classified as an "internal failure". As long as detecting the “TX Output Power Error”, the VHF-AM transceiver stays in RX mode. • TX Synthesizer Error The VHF-AM transceiver monitors the TX synthesizer while generating the TX signal. If error behavior is detected and the /PTT input is active (low), the VHF-AM transceiver indicates "TX synthesizer error" This error classifies as "internal failure". As long as detecting the "TX Synthesizer Error", the transmitter stays in TX-Off-condition. • TX OFF-Overtemp Error [W] 20 10 TX Hot no TX Hot TX Off no TX Off 75 85 95 [ C] Figure 18 Thermal behavior for TX function The VHF-AM transceiver monitors the heat sink temperature. If the heat sink temperature exceeds +95 °C at the point of measurement and on the /PTT input a low state is detected, the VHF-AM transceiver indicates a "TX OFF-Overtemp Error". As long as the error is detected, the VHF-AM transceiver stays in TX-off-condition. The error indication disappears when the heat sink temperature has fallen below +85 °C at the point of measurement. This error is indicated as an "external failure". • TX Hot Error The VHF-AM transceiver is monitoring the heat-sink temperature. If the heat sink temperature exceeds +85 °C at the point of measurement and on the /PTT input a low state is detected, the VHF-AM transceiver indicates a "TX Hot Error". The error indication disappears when the heat sink temperature has fallen below +75 °C at the point of measurement. This error is indicated as a warning. 38 RT6512 DV17501.03 Issue 01 June 2015 Operating Instructions Start-Up As long as the "TX Hot Error" indication is ON and the VHF-AM transceiver is in the TX mode, TX output power is reduced to a safe level. • Antenna VSWR Error In TX mode, the VHF-AM transceiver is monitoring the VSWR at the antenna connector. If the VSWR mismatches to more than 1:8, "Antenna VSWR Error" indication is ON. If an "Antenna VSWR Error" is detected, the VHF-AM transceiver stays still in TX mode. As long as the error exists, the output power is reduced to a safe level. This error is indicated as an "External Failure". • Stuck PTT Error When the PTT-key is pressed, a timer starts. The time limit setting is adjustable in the factory setup from 30 seconds to 180 seconds. Factory setup provides "Stuck PTT Error” detection and also the enabling / disabling of this function. When detecting a "Stuck PTT Error", the VHF-AM transceiver switches to the RX-mode. As long as this error is indicated the VHF-AM transceiver stays in a Stuck-PTT-condition. 3.2.1.1. Initiated Built In Test (IBIT) The test routine BIT activates by special command via serial interface. The green LED on the VHF-AM transceivers front side flashes for approx. 2 seconds during IBIT is running. Note: Interrupting an already started self-test is not possible. The test routine IBIT checks the following functions: • PSB Error • RCU Lost Connection Error • Channel Error • RX Synthesizer Error • RX AGC Error • TX Output Power Error • TX Synthesizer Error • TX OFF-Overtemp Error • TX Hot Error • Antenna VSWR Error • Stuck PTT Error 3.2.1.2. Power On Built In Test (PBIT) The PBIT triggers automatically and runs immediately after the VHF-AM transceiver switches on. The PBIT checks the same function as described in the IBIT. The Error indication is the same as IBIT. The VHF-AM transceiver immediately produces a NOGO-Audio Signal on the LINE_OUT after detecting a failure. 3.2.1.3. Continuous Built In Test (CBIT) During the VHF-AM transceiver is operating the CBIT test runs permanently "in the background" and controls: • PSB Error • RCU Lost Connection Error • Channel Error • RX Synthesizer Error • TX Output Power Error • TX Synthesizer Error • TX OFF-Overtemp Error • TX Hot Error • Antenna VSWR Error DV17501.03 Issue 01 June 2015 RT6512 39 Operating Instructions Start-Up 3.2.1.4. Audible Error Announcement The VHF-AM transceiver immediately produce NOGO-audio signal at the LINE_OUT if the error indication is changing from: "no error” or “warning" to: "internal failure” or/and “external failure”.

After test is completed, the VHF-AM transceiver automatically turns to receive mode. 3.2.1.11. Error-History-Flags in the Service Set up Any error occurring one or more time(s) is setting the corresponding error-history-flag. The errorhistory-flag will be hold for a time of 10 operating seconds after the error has disappeared. The state of all error-history flags is stored at each power OFF. The error-history-flags are readable in the service setup. The error history-flags are erasable immediately from the service setup. 3.3.
