The M760REM-USER is a controlled document and may not be chnaged without the prior consent of Miroair Avionics. 2.0 Development History The M760REM is a development of the Microair M760 Airband Transceiver. This development replaces the human interface display assembly, with a serial data interface. The M760REM retains the serial data SL30 interface from the M760, for control over the active frequency, standby frequency, and dual monitor mode. The serial data interface replaces all controls normally accessible from the display assembly, with serial command codes. A third party control unit can use these commands to maintain full control and operation of the M760REM. Existing controls and interfaces such as the microphone audio in, headphone audio out, and PTT line remain unchanged from the original M760. Microair Avionics M760REM User Manual M760REM-USER 01R1.doc Page 4 of 12 10 th March 2011 3.0 Installation The M760REM has no display or human interface control. The unit can fixed to any appropriate aircraft structure which is inside the aircraft cabin. The M760REM should be located clear of air vents or cabin heating, and should not be subject to outside weather. For pressurised aircraft, the M760REM shall be located inside the pressure hull, in a temperature controlled space. 3.1 Mounting The M760REM has mounting flanges with four M4 x 10 (5/32” x 3/8”) slotted holes. 3.2 Connection Electrical connection is made using a Sub- D15 connector, which is held in place using thumbscres or lock bolts (4-40). The RF connection is made using a 50 ohm BNC connector. 3.3 Location The location of the M760REM should consider access to the adjustment trimpots for microphone gain, sidetone level, and headphone aduio level. Consideration should also be given to the connector and cable bending radius for the wiring harness and coax cable. 3.4 Antenna The M760REM is compatible with any TSO C37d/C38d compliant Airband antenna. The coaxial cable shall be 50 ohm (eg RG58/RG400).

Where necessary, the performance items are referenced to RTCA standards, which define the performance items and the method of measurement. All performance measurements for this document are made at Microair’s factory at Bundaberg Australia, under standard environmental conditions. 2.0 Development History The M760REM is a development of the Microair M760 Airband Transceiver. This development replaces the human interface display assembly, with a serial data interface. The M760REM retains the serial data SL30 interface from the M760, for control over the active frequency, standby frequency, and dual monitor mode.

Microair Avionics M760REM Declaration of Design Performance M760REM-DDP 01R3.doc Page 4 of 21 18 th April 2011 3.0 Product Description The M760REM consist of three major sub assemblies:  AF Board (p/n M760_AF_01R18-6A)  RF Board (p/n M760_RF_01R19-2)  Micro Board (p/n M760UAV_MICRO_01R1-0) 3.1 AF Board The AF (Audio Frequency) board holds the following systems:  IF filter, three stage strip, & Detector  AGC  Mute  Microphone input and audio compression  PTT switching  Audio PA  DB15 electrical connector  RS232 line driver  9.5V regulator  5V regulator Microair Avionics M760REM Declaration of Design Performance M760REM-DDP 01R3.doc Page 5 of 21 18 th April 2011 3.2 RF Board The RF (Radio Frequency) board holds the following systems:  TCXO  PLL/VCO  Receiver front end & LP filter  Transmitter & PA  Modulator Microair Avionics M760REM Declaration of Design Performance M760REM-DDP 01R3.doc Page 6 of 21 18 th April 2011 3.3 Micro Board The Micro Board holds the following systems:  Microcontroller  Squelch adjust  Headphone audio adjust  5V regulator Microair Avionics M760REM Declaration of Design Performance M760REM-DDP 01R3.doc Page 7 of 21 18 th April 2011 3.4 Chassis The M760REM has a sheet aluminium chassis with a divider plate in the centre, to which the AF and RF boards are fixed. The MICRO board is fixed to the front of the divider plate. Harnessing from the MICRO board connects the AF and RF boards. The chassis is completed by a base plate, front plate, back plate, and top cover. The top cover features mounting flanges, to facilitate installation. Microair Avionics M760REM Declaration of Design Performance M760REM-DDP 01R3.doc Page 8 of 21 18 th April 2011 4.0 Frequency Tuning The M760REM frequency control is via the SL30 command interface. Upon receipt of a valid “set active” or set standby” command, the microcontroller will decode the frequency value and pass it to the PLL via an SPI interface. The PLL will set the control volts for the VCO, which in turn provides the signal source to the transceiver. 5.0 PC Emulation Microair provides a PC application to emulate a standard M760 display. The emulator interfaces to the M760REM via the PC’s serial port, and used the SL30 command set. All functions can be tested, and the application provides a communications window to confirm the command traffic.

Operating Procedure for M760REM Radio Document: 002-760-0150 Date: 03-15-11 Revision: New Page 1 of 3 Operating Procedure for M760UAV VHF COM radio Equipment setup: Required equipment: 14 VDC power supply, 0-3 A PC with RS232 port, 9-pin connector Test harness provided by PS Engineering Microair Control panel software provided by PS Engineering Installing the Terminal Program File: Extract file M760 Test Panel PC App.zip to local hard drive Launch the file, m760UAV.exe, from PC App folder. Using the Terminal Program: With the EUT connector to the computer RS-232 port, and after power applied, click the Connect button. Operating Procedure for M760REM Radio Document: 002-760-0150 Date: 03-15-11 Revision: New Page 2 of 3 The display will read the last used frequencies in the radio. The M760REM can now be controlled using the terminal program. Frequency control (1) Four preset frequencies are available in the Frequency Control section (band ends and mid band) that enter into the active frequency, plus a direct access frequency entry that can be entered into either active or standby frequency register. Frequencies are entered with the decimal point, and all significant digits for 25 kHz channels. NOTE: The EUT only transmits in the frequency range 118.00 to 136.975 MHz. Frequencies bwtween 108.00 and 117.95 are receive only in the aeronautical navigation band. Receiver squelch control (2) The receiver squelch threshold is adjusted in the “Squelch Function” section. The receiver squelch can be instantly set at the ends and middle of the range, in increment of a single step (single chevron) or in increments of eight steps (double chevrons). Operating Procedure for M760REM Radio Document: 002-760-0150 Date: 03-15-11 Revision: New Page 3 of 3 NOTE: The higher the squelch number, the smaller the RF signal is required to open the squelch. Max (127) is the squelch completely open. Miscellaneous (3) Misc Functions are for troubleshooting and debugging, and not used for control. Receiver volume control (4) Unit receiver volume is factory set to maximum, and screwdriver adjustable through the hole on chassis. Turn clockwise to decrease volume. Shutdown procedure Remove power from the EUT, and exit the terminal program.

Microair Avionics M760REM Declaration of Design Performance M760REM-DDP 01R2 Page 9 of 18 11 th March 2011 4.0 Frequency Tuning The M760REM frequency control is via the SL30 command intrface. Upon receipt of a valid “set active” or set standby” command, the microcontoller will decode the frewquency value and pass it to the PLL via an SPI interface. The PLL will set the control volts for the VCO, which in turn provides the signal source to the transceiver. 5.0 PC Emulation Microair provides a PC application to emulate a standard M760 display. The emulator interfaces to the M760REM via the PC’s serial port, and used the SL30 command set. All functions can be tested, and the application provides a communications window to confirm the command traffic. 6.0 Receiver Function The M760REM has a superhetrodyne receiver with an IF frequency of 10.7MHz. The receiver is “high side” tuned (eg for 127.000MHz the VCO is tuned to 137.700MHz. The M760REM is also fitted with a dual monitor function, where the PLL is rapidly switched between the active and standby frequencies. If carrier is detected, the switching process is locked to receive that signal. When carrier is no longer present the M760REM will return to rapid switching between the active and standby. If the M760 is receiving on the standby frequency, it will regularly resample the active for the presence of carrier. If carrier is detected on the active, the M760REM will switch back to the active frequency. The M760 can be pout into or out of dual monitor by setting the applicable bit in either the set active or set standby commands.
