GENERAL.
The AM-2.5E and AM-5E transmitters are designed for complete remote con
trol operations (refer to Figure 2-8 ). The transmitters will interface with almost any re
mote control unit such as the Broadcast Electronics model VMC-16 voice remote control
system. The following text presents a description of the transmitter remote control func
tions and indications. The remote control connections are located at 25-pin D-type con
nectors J1 and J2. J1/J2 are located on the transmitter top-panel. The remote control
functions are activated using a +5 to +15 volt dc signal. The remote indication functions:
1) require current limiting resistors and 2) provide up to 100 mA for indicators. A +5 volt
supply is provided at J1 for remote control operations.
2-60. Power Level Controls/Indicators. The transmitter is designed with five customer adjust
able operating power controls. The controls are located at J1-1 through J1-5. A +5 to +15
volt dc signal is required to activate the desired function.
2-61. Indications of power level control operations are located at J1-7 through J1-11. The power
level status indicators will go LOW (0 volts dc) when activated.
2-62. Transmitter Off Control/Indicator. The transmitter off control is located at J1-6. A +5 to
+15 volt dc signal is required to operate the transmitter to off. The indicator for the trans
mitter off control is located at J1-14. The off indicator will go LOW (0 volts dc) when acti
vated.
2-63. Power Level Raise/Lower Controls. The transmitter is designed with raise and lower con
trols to adjust the transmitter output power level. The controls are equipped with ability
to raise/lower power from 10% to 15% of the selected output power level. The controls are
located at J1-15 and J1-16. A +5 to +15 volt dc signal is required to activate the desired
function.
2-64. Antenna Interlock Input. The antenna interlock inputs are designed for the connection of
the status signals from antenna A, B, and C. The inputs are located at J1-19 through
J1-21. The inputs require a +5 to +15 volt dc signal to indicate an antenna ready status.
2-65. Transmitter Mute Input. The transmitter mute input is designed to mute the transmitter
when activated. The input is located at J1-22. The input requires a +5 to +15 volt dc sig
nal to mute the transmitter.
2-66. Remote Failsafe Input. The remote failsafe input is designed for the remote control unit
failsafe control line. The input is located at J1-23. The input requires a +5 to +15 volt dc
signal to indicate an enabled remote control unit.
2-67. External Interlock Input. The external interlock input is for the connection of an interlock
external to the transmitter. The input is located at J1-24. The input requires a +5 to +15
volt dc signal to indicate a closed interlock.
2-68. Int5V. The int5 volt supply is provided for the external interlock. The +5
volt supply is located at J1-25.
2-69. Exciter Mode Controls/Indicators. The transmitter exciter is designed to be operated in
the mono left, mono right, mono L+R, or stereo modes of operation. The controls are lo
cated at J2-1 through J2-4. A +5 to +15 volt dc signal is required to activate the desired
function.
2-70. Indications of exciter modes of operations are located at J2-5 though J2-8. The exciter
mode indicators will go LOW when activated.
2-71. Remote Forward/Reflected Power Meter Indications. Remote reflected power meter indi
cations are located at J2-9 and J2-10. The indications are designed to be programmed for
+5 volt dc full-scale meter indications or +2.5 volt dc full-scale meter indications.
