2.4GHz Transmitter Inputs & Controls:
1. POWER INPUT
Accepts a 6-12 Vdc power source such as the standard 7 Vdc adapter (Trango part
number PT07800-1), or an optional battery. The nominal current draw is 145
milliamperes. If using an adapter from a third party, use a well-regulated 200 mA
minimum output supply.
Do not use the PT07800-1 to power a camera or video
distortion may occur.
2. ALARM INPUTS
These inputs are used to send alarm signals to the receiver. They sense an open or
closed state and reflect that state to the receiver whenever it changes. The alarm
inputs operate independently of each other. The transmitter is capable of sending
either
alarms
or
stereo audio, selectable via the Stereo/Alarm switch.
3/4. RIGHT & LEFT AUDIO INPUTS
Designed to mate to standard RCA connectors, each input accepts 1 Vpp audio input
and is terminated with 600
Ω
unbalanced configuration. It is designed to interface to
“lineout” audio sources. A preamplifier must be used to connect a microphone to this
input.
5. STEREO/ALARM SWITCH
When this switch is in the “R Audio Active” position, stereo audio transmission is
enabled. This permits the transmission of stereo audio with no alarms. When it is in
the “Alms Active” position, R audio is disabled. In its place, the alarms are
transmitted. The left audio(mono) is always active.
6. VIDEO INPUT
Designed to mate to a standard RCA-F connector, this input accepts 1Vpp video in
both NTSC and PAL formats. This input is terminated with 75
Ω
. RCA-BNC
adapters are available for use with some cameras and VCRs.
7. CHANNEL DIP SWITCH/ STATUS LED
This switch controls the transmitter channel. Remember to change the receiver
channel as well, since it is not automatically changed when the transmitter channel is
changed. The status LED will blink to indicate the channel number after the switch
is changed.

DO NOT APPLY EXTERNAL VOLTAGES TO THE ALARM INPUTS AS
PERMANENT DAMAGE TO THE UNIT MAY RESULT. USE ONLY DRY
CONTACTS WITH THESE INPUTS.
