Using the Combination Power/Video Connector(s)
As an alternative to using standard audio and video interconnect cables,
the VT900-3 transmitter and the VR900-3 receiver each provide a
combination Power/Video connector on the unit’s rear panel. The pinout
of these connectors is the same for both transmitter and receiver.
The pinout of the combination Power/Video/Audio jack, and its mating
plug (not supplied), is illustrated in Figure 3 and Table 1. Contact Applied
Wireless, Inc. if you wish to purchase an optional Combination
Power/Video cable.
Signal Strength Indicator (VR900-3 Receiver)
The VR900-3 receiver will display the relative strength of the received RF
signal, by illuminating some or all of the four red Signal Strength LEDs on
the front panel. The Signal Strength indicator(s) will also illuminate if
local in-band interference is present. If the Signal Strength LEDs are
indicating that a strong signal is being received, and yet the video and/or
audio quality is poor, turn off the transmitter (by unplugging its power
connector). If the receiver’s Signal Strength LEDs continue to indicate
reception of a strong signal, changing the channel of operation (on both
the transmitter and receiver) may improve the results.
