1• Verify proper operation of camera and monitor/event recorder using coaxial cable prior
to installing wireless link per the diagram below.
2• Connect the power adapter to the #6 terminals on the transmitter and receiver units per
the picture below.
3• Install transmitter (VST2500) and receiver (VSR2500) units in desired location to a wall
using the supplied mounting hardware as shown below. For optimum performance the units
should be mounted at a height of 6-7 feet above the ground and no more than 300 feet apart.
4• Connect the video audio and alarm inputs and outputs, following the color sche mes on
the cables and connectors.
5• Plug the AC adapters into the wall outlet. The LED on the unit should come on and blink
several times. The number of blinks indicates the channel. Both units must be on the same
channel for proper operation.
6• Adjust the units until the best picture is obtained. Normally this will occur when the
units are oriented as shown below, but in some cases the best picture may occur when the
units are not aimed directly at each other.
7• After the picture has been optimized tighten the bracket down using the knob on the side
of the bracket as shown below.

System Description:
The STINGRAY Wireless Video System is a professional quality system designed for
sending composite NTSC or PAL video, audio, and alarm signals using 2.4 GHz wireless
technology. The system consists of a VST2500 transmitter, VSR2500 Receiver, and
power adapters. The system is ideal for permanent or temporary video links due to its
portable nature and easy installation. It is not designed for operation while in motion.
It is not designed for outdoor operation

Installation Hints:
The STINGRAY system is factory-configured for operation on channel 1 with right and
left audio operational. The system has a very directional transmission pattern that
increases the transmission range while rejecting interference. If installed properly, the
system will provide superior picture quality, even when transmitting through walls in a
typical home or office setup.
To obtain the best picture quality and transmission distance, the following rules of thumb
should be followed:
1) Mount the transmitter and receiver antennas above human and mechanical traffic
but away from metallic objects.
2) Keep the transmission path as open as possible. Objects such as walls, ceilings
and metallic objects near the transmission path can reflect signals and may reduce the
transmission distance.
3) If operating more than one system in an area, set the channels as far apart as
possible on each system (i.e. system 1 use channel 1, system 2 use channel 4).

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 600Ω 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 75Ω. 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.
CAUTION

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

2.4GHz Receiver Inputs/Outputs & 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 400
milliamperes. If using an adapter from a third party, use a well-regulated 6-
12Vdc/500mA output supply.
2. ALARM OUTPUTS
These are dry contact relay outputs which can sink 1 ampere at 40 V AC/DC. When
the corresponding transmitter alarm input closes or opens, this output will close and
open as well. Consider these outputs mirrors of the transmitter alarm inputs. These
outputs are independent and can be used to turn on peripheral devices such as video
recorders and audible alarms.
3/4. RIGHT & LEFT AUDIO OUTPUTS
Designed to mate to a standard RCA male connector, this provides a 1.5 Volt peak-
to-peak audio output and should be terminated in a minimum 600 Ω load, as is found
in most “line in” audio inputs.
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, alarm transmission is enabled. Left audio reception is
always enabled.
7. VIDEO OUTPUT
Designed to mate to a standard RCA male connector, this provides a 1 Volt peak-to-
peak video signal output. This must be terminated with 75 Ω. RCA to BNC adapters
are available for use with some monitors and VCR inputs.
8. CHANNEL DIP SWITCH/ STATUS LED
This switch controls the receiver channel. Remember to change the transmitter
channel as well, since it is not automatically changed when the receiver channel is
changed. The status LED will blink to indicate the channel number after the switch
is changed.

INTERFERENCE
If interference such as lines in the pictures is observed, changing the transmission
channel may cure the problem.
Also, AC generators in close proximity to the transmitter or receiver may cause lines
in the picture. Move the unit away from the source of the interference.
NO PICTURE
Check that the transmit and receive channels are set the same, and make sure the
LED is glowing.
Verify all connectors are tight.
POOR PICTURE QUALITY
Raise transmitter and receiver antennas above ground and away from obstacles and
traffic, including foot traffic.
VIDEO TOO DARK
Make sure that any monitors/peripheral equipment connected to the video source are
set to high impedance termination since the VTX2500 has a built-in 75 Ω
termination.
VIDEO TOO BRIGHT
Make sure that the receiver video output line is terminated with 75 Ω.
