Pin - Signal Name
t – RS-232-RTS
This pin is used to transfer information to the MTM guard.
u - HOMING SIGNAL STRENGTH
This output produces an output based on the signal strength that varies between
0 and 8 VDC, and is capable of driving a 2k Ohm load. This signal has a 3 dB
bandwidth between DC and 50 Hz.
v - MN RX 180 ENABLE
Grounding this input causes 180 degrees of phase shift in the main received
audio.
w - WIDE BAND GUARD RX AUDIO OUT
This output is the single ended wide band guard audio output. It is capable of
driving a 2k Ohm impedance and has a 3 dB bandwidth of 1 Hz to 27.5 kHz. The
output is adjustable from .1 Vrms to 1.5 Vrms and set to .6 Vrms.
x - GD RX 180 ENABLE
Grounding this input causes 180 degrees of phase shift in the guard received
audio.
y - GUARD RX AUDIO
This output is the single ended guard audio output. It is capable of driving a 2k
Ohm impedance and has a 3 dB bandwidth of 1 Hz to 3kHz. The output is
adjustable from .1 Vrms to 1.5 Vrms and set to .6 Vrms.
z - TX 180 ENABLE
Grounding this input causes 180 degrees of phase shift in the transmitted audio.
This phase shift may be required when using an external encryption device.
AA, BB, CC, DD – 28 VDC PWR
Input Aircraft power pins.
EE, FF, GG, HH – PWR GND
Input Aircraft power ground pins.
