6. PREPARATION FOR USE
6.1. Unpacking
Carefully remove the product from the shipping container and make sure all listed furnished items are
included as noted in the respective section. Inspect all items for damage. If any item is omitted from the
shipment or appears damaged, contact AMP with detailed description of problem.
6.2. Transmitter Pre-Test
Although each unit is thoroughly tested at the factory for both functional and environmental performance,
a minimal amount of pre-testing should be done by the operator before placing the transmitter into
service. The transmitter, an appropriate AMP receiver, transmit and receive antennas, a video camera, a
video monitor, proper cabling, and DC power supplies are the only components required to perform a
functional test of the transmitter. If testing audio or data, an audio source (microphone or line level) or
data source and a speaker or headphones (audio) or data monitor will also be required.
The transmit and receive antennas should be situated at a distance of greater than 25 feet apart to
prevent serious damage to or destruction of the receiver’s front end. Set up the receiver and make all
necessary adjustments in accordance with that unit’s Quick Start Guide. Connect the receiver video
output to the video monitor and, if testing audio or data, connect the receiver audio or data output to the
speaker or headphones (audio) or data monitor as appropriate.
Verify DC power supplies are between +11 and +16 Vdc. With the DC Power Cable (MDM-9S connector)
DISCONNECTED from the transmitter, connect DC power supply to DC Power Cable (Pin1 = positive DC
input, Pin2 = negative DC input (ground)). Do not connect DC Power Cable to transmitter until all other
connections are complete.
Connect the transmit antenna to transmitter RF output connector (SMA). Connect the Video Adapter
Cable to the transmitter video input connector (SSMA, SMB optional). Connect the Video Cable between
the Video Adapter Cable and video camera. If testing audio or data, connect the audio or data source to
the Audio/Data Cable (MDM-9P connector) and Audio/Data Cable to the transmitter (mates to MDM-9S
connector on transmitter). Refer to Section 2.2 for a complete VST1 wiring diagram.
Configure switches as instructed in Section 7.2. Connect DC Power Cable to transmitter (mates to MDM-
9P connector on transmitter). Video should be observed on the monitor and audio heard through the
speaker / headphones once the transmitter locks on frequency (requires several seconds). If no video or
audio/data (as applicable) is present, refer to Section 8.2 for troubleshooting instructions.
6.3. Receiver Pre-Test
Although each unit is thoroughly tested at the factory for both functional and environmental performance,
a minimal amount of pre-testing should be done by the operator before placing the receiver into service.
The receiver, an appropriate AMP transmitter, transmit and receive antennas, a video camera, a video
monitor, proper cabling, and DC power supplies are the only components required to perform a functional
test of the receiver. If testing audio or data, an audio source (microphone or line level) or data source and
a speaker or headphones (audio) or data monitor will also be required.
The transmit and receive antennas should be situated at a distance of greater than 25 feet apart to
prevent serious damage to or destruction of the receiver’s front end. Set up the transmitter and make all
necessary adjustments in accordance with that unit’s Quick Start Guide. Connect the video camera to
the transmitter video input and, if testing audio or data, connect the audio or data source to the transmitter
audio or data input(s).

AMN-V-C 10
Verify DC power supplies are between +11 and +16 Vdc. With the DC Power Cable (MDM-9S connector)
DISCONNECTED from the receiver, connect DC power supply to DC Power Cable with the correct
polarity (Pin1 = positive DC input, Pin2 = negative DC input (ground)). Do not connect DC Power Cable
to receiver until all other connections are complete.
Connect the receive antenna(s) to receiver RF input connector(s) (SMA). Connect the Video Cable
between the receiver video output connector (BNC) and the video monitor. If testing audio or data,
connect the speaker or data monitor to the I/O Cable or headphones to the 3.5mm Audio Jack. Refer to
Section 3.2 (VSR1) or 4.2 (VDR1) for a complete wiring diagram.
Configure switches as instructed in Section 7.2. Connect DC Power Cable to receiver (mates to MDM-9P
connector on receiver). Video should be observed on the monitor and audio heard through the speaker /
headphones. If no video or audio/data (if applicable) is present, refer to Section 8.2 for troubleshooting
instructions.
7. INSTALLATION AND OPERATING INSTRUCTIONS
7.1. Use and Function of Connectors
AMP V series products are simple to install, requiring only connection to the antenna, camera, audio or
data (if applicable), and DC power supply using the appropriate cables and jacks for transmitters and
requiring only connection to the antenna, monitor, speaker or headphones, and DC power supply using
the appropriate cables and jacks for the receivers. The use and function of the connectors are in the
respective product sections.
7.2. Use and Function of Switches
The available switches and functionality will depend on the model and configuration of your V series
product.
7.2.1. Frequency Selection Switches:
Frequency selectability is standard on all V Series products providing RF frequency control with either
rotary switches accessible through the chassis lid, programmable presets, or remote programming.
To program the desired RF frequency using rotary switches, position the rotary switches as shown in the
Frequency Selection Chart in Section 10. To program the desired RF frequency using remote interface,
refer to the V Series Interface Control Document (ICD).
7.2.2. LINE – MIC Switch (transmitters only)
The Line-Mic slide switch is accessible through the chassis lid on V series products equipped with one or
two audio subcarrier. This switch only works when the transmitter or receiver is in manual mode. When
in Preset or Remote modes, the switch is bypassed. When switched to LINE the input level is set to -
10dBV. When switched to MIC the input level is set to -55 dBV. When you have two subcarriers, both
audio levels will be set the same.
7.2.3. RS232 – TTL Switch (transmitters only)
The RS232-TTL slide switch is accessible through the chassis lid on V series products equipped with one
or two data subcarrier. This switch only works when the transmitter or receiver is in manual mode. When
in Preset or Remote modes, the switch is bypassed. Use this switch to select between RS232 and TTL
(3.3V) data inputs. For transmitters equipped with RS422 data subcarriers, the switch will not be
functional. When you have two subcarriers, both data subcarriers are controlled by the single switch.

AMN-V-C 11
7.2.4. AUD ON – AUD OFF Switch
The Aud On – Aud Off slide switch is accessible through the chassis lid on V series products equipped
with one or two audio subcarrier. This switch only works when the transmitter or receiver is in manual
mode. When in Preset or Remote modes, the switch is bypassed. This switch will turn the audio
subcarrier on or off. When you have two subcarriers, it turns on or off both audio subcarriers.
7.2.5. DAT ON – DAT OFF Switch
The Dat On – Dat Off slide switch is accessible through the chassis lid on V series products equipped
with one or two data subcarrier. This switch only works when the transmitter or receiver is in manual
mode. When in Preset or Remote modes, the switch is bypassed. This switch will turn the data
subcarrier on or off. When you have two subcarriers, it turns on or off both data subcarriers.
7.2.6. HIGH PWR – LOW PWR (transmitters only)
V Series Transmitters may be optionally configured for up to four power output levels. In manual mode,
RF output power level is controlled with a HIGH PWR – LOW PWR switch accessible through the chassis
lid. Only the highest and lowest power can be selected in manual mode. If your transmitter is configured
with 3 or 4 power output levels, you must use the presets or remote mode to select the middle power
levels. The switch is inactive if the transmitter is purchased with only one power output.
To select the higher RF output power level, position the slide switch to HIGH PWR as indicated on the
unit label. To select the lower RF output power level, position the slide switch to LOW PWR as indicated
on the unit label.
7.2.7. SECURE - CLEAR Switch
All AMP V series Video Transmitters and Receivers are standard equipped with video inversion,
selectable with a Secure-Clear slide switch accessible through the chassis lid. When selected, the phase
of the video signal is inverted (shifted 180o) in the transmitter and re-inverted in the receiver, providing a
basic level of security. If an inverted video signal is detected by a receiver not configured for inversion,
the resulting picture is scrambled.
To select standard video (no inversion), position the slide switch to CLEAR as indicated on the unit label.
To select inverted video (phase inversion), position the slide switch to SECURE as indicated on the unit
label.
The video inversion switch position on AMP’s Receivers must match that of the transmitter or the picture
will appear scrambled. If using AMP’s Transmitters with other receivers or vice-versa, position the Video
Inversion slide switch to CLEAR.
7.2.8. DIM / BRIGHT / OFF (receivers only)
The Dim/Bright/Off switch is present on VSR1 and VDR1 receivers equipped with LED Received Signal
Strength Indicator (RSSI) meters. It is a momentary switch, accessible through the chassis lid, that
toggles through DIM, BRIGHT, and OFF for the LED RSSI meters (when applicable).
7.3. Camera Supply Output (transmitters only)
V Series Transmitters offer +12 Vdc Camera Supply Output. The Camera Supply Output is linearly
regulated with approximately 0.5V Drop-Out Voltage, meaning the Camera Supply Output voltage will be
+12 Vdc for all transmitter DC input voltages above +12.5 Vdc. For all transmitter DC input voltages less
than +12.5 Vdc, the Camera Supply Output voltage with be approximately 0.5 Vdc less than the input
voltage. The output current limit on the +12 Vdc Camera Supply Output is 250 mA. The Camera Supply
Output is only active when DC power is applied to the Transmitter.

AMN-V-C 12
7.4. Auxiliary Supply Output (receivers only)
V Series receivers offer +12 Vdc Auxiliary Supply Output. The Auxiliary Supply Output is linearly
regulated with approximately 0.5V Drop-Out Voltage, meaning the Auxiliary Supply Output voltage will be
+12 Vdc for all transmitter DC input voltages above +12.5 Vdc. For all receiver DC input voltages less
than +12.5 Vdc, the Auxiliary Supply Output voltage with be approximately 0.5 Vdc less than the input
voltage. The output current limit on the +12 Vdc Auxiliary Supply Output is 1.5 A. The Auxiliary Supply
Output is only active when DC power is applied to the Receiver.
7.5. Audio Output(s) (receivers only)
V Series Receivers, when equipped for audio, offer dual buffered audio outputs for each channel. Up to
two channels may be specified.
When one channel is specified, the audio output signal is available on both pins 1 (-10 dBV level) and 2
(+4 dBu level) of the Audio Connector and the mono prong of the 3.5mm Jack (-10 dBV level). The
outputs are buffered providing one audio output for monitoring (3.5mm Jack) and one for recording (Audio
Connector). All audio outputs are 100 Ohms output impedance, unbalanced, at the specified line levels.
When two channels are specified, the audio output signals are available on pins 1 (-10 dBV level, Audio
Left), 2 (+4 dBu level, Audio Left), 4 (-10 dBV level, Audio Right), and 5 (+4 dBu level, Audio Right) of the
Audio Connector and the mono (-10 dBV level, Audio Left) and stereo (-10 dBV level, Audio Right) prongs
of the 3.5mm Jack. A 3.5mm Stereo Plug to Dual Mono Jack Adapter may be used to separate the audio
signals into two 3.5mm mono ports. All audio outputs are buffered providing simultaneous monitoring and
recording of all outputs. All outputs are 100 Ohms output impedance, unbalanced, at the specified line
levels.
7.6. Signal Strength Meters (receivers only)
V Series Receivers are standard equipped with single (VSR1) or dual (VDR1) Signal Strength Meters on
the chassis. Received signal strength is indicated by the meter(s) when the receiver is powered.
The LCD meter reads similar to an analog fuel gauge, such that when the bar is towards the left signal
strength is low (far left ≈ -90 dBm) and when the bar is towards the right signal strength is high (far right ≈
-30 dBm).
The LED meter reads similar to cell phone bars, such that when one LED bar is lit the signal strength is
low and when all bars are lit the signal strength is high. A single flashing LED indicates that the signal is
at risk of being lost or has been lost. Units equipped with LED Signal Strength meter(s) utilize either a set
of slide switches clearly labeled for turning the LED display(s) On/Off and Dim/Bright or a single
pushbutton switch which toggles among Dim/Bright/Off when depressed.
The Signal Strength Meters may aide in antenna alignment. The outline drawings for each receiver show
the relationship between RF Input ports and RSSI meters. RSSI Meter-1 indicates RSSI for RF Input-1
and RSSI Meter-2 (VDR1) indicates RSSI for RF Input-2. Position the antennas to maximize RSSI on
both input ports.
If a meter exhibits a display full of flashing bars, signal strength is excessive and damage to the receiver
front end may occur. Do not rely on flashing bars to indicate levels that may cause receiver
damage. Damage may occur at lower levels, thereby preventing flashing bars from occurring.
On the VDR1 Series receivers, a proprietary voting circuit continuously samples RSSI from both input
ports and passes the higher power signal to the video output. The RSSI output pin on the I/O connector
is derived from the higher of the two signals and is proportional to the higher of the two meters at all
times.

AMN-V-C 13
7.7. Use of Heat Sink
VST1 Transmitters operating at or above 500 mW require the use of a heat sink or must be securely
fastened to an adequate heat sinking object or surface. Advanced Microwave Products recommends the
SNK3513-S06B0!heat sink for use with the VST1 transmitter.
V Series transmitters should be fastened to AMP heat sinks using provided pan head or socket head
screws with lock washers. Use of thermal grease, such as Wakefield Engineering 120 Series Thermal
Compound, to improve thermal conduction between transmitter base plate and heat sinking surface will
reduce unit temperature and increase product reliability.
7.8. Mating Connectors
The V series transmitters and receivers use an industry standard 9 Pin Micro-D connector for power and
communication connections and 9 socket Micro-D connector for audio or data where applicable. AMP
offers optional mating connectors to wire your product. AMP mating connector WHSMDM9-SSLH0 is
used for power and communication and AMP mating connector WHSMDM9-SPLH0 is used (when
applicable) for audio or data. The mating connectors come with 18” flying leads and are
colored in compliance with MIL-STD-681E Identification Coding and Application of Hookup
and Lead Wires as shown in the diagrams below.

AMN-V-C 14
7.9. Initial Adjustments and Settings
There are no initial adjustments or settings necessary to use AMP products other than proper
configuration of the switches as outlined above in Section 7.2. To assure optimum performance, the user
should be familiar with the camera, monitor, microphone, speaker/headphones, data source, and data
monitor used with this video system.
7.10. Shut Down
If the transmitter or receiver is to be shut down only briefly, simply remove DC voltage from the DC Power
Cable or disconnect DC Power Cable from transmitter. If the unit is to be shut down for an extended
period, all external cabling including the antenna should be removed and the unit should be stored in a
container and placed in a clean, dry environment.
8. MAINTENANCE INSTRUCTIONS
8.1. Cleaning
AMP Transmitters and Receivers should be periodically wiped off with a clean, damp cloth. For more
thorough cleaning, dampen a clean cloth with glass cleaner and wipe off unit. Ensure units are
completely disconnected from their power sources before cleaning.
8.2. Troubleshooting
To avoid poor performance, ensure all mating connectors are tightly fastened, clean, and have no pins
bent or damaged.
Verify configuration of all switches (refer to Section 7.2). If poor or no operation is observed, ensure the
external DC voltage supply is between +11 and +16 Vdc with correct polarity. All AMP Transmitters and
Receivers have over-voltage and reverse polarity protection circuits. If the input voltage is over +16 Vdc,
remove the DC Power Cable from the unit, reduce the DC voltage to between +11 and +16 Vdc, and
reconnect the DC Power Cable. If the input voltage is negative polarity, remove the DC Power Cable
from the unit, reverse the connections between the DC voltage supply and DC Power Cable, and
reconnect the DC Power Cable.
If all connections are adequate, switches are correctly configured, and DC voltage is correctly applied,
check the video camera, video cable, and antenna for damage. A monitor may be connected directly to
the camera to verify proper camera operation.
For audio applications, if receiving video but no audio, check connections between microphone and Audio
Cable. Also check microphone and Audio Cable for damage.
If these efforts fail, do not attempt to repair the unit. Please contact AMP with a detailed description of the
problem. Depending on the nature of the problem, AMP may provide further troubleshooting assistance
or advise the entire system be returned for repair and retest.
Caution: Removal of the cover constitutes breaking the seal and VOIDS PRODUCT WARRANTY.

10. FREQUENCY PROGRAMMING CHART
AMP channelized V Series Transmitters and Receivers can be programmed via three rotary selection
switches located on the top of the product. There are three modes for configuration: Manual Mode,
Preset Configuration Mode, and Remote Configuration Mode. The Manual Mode utilizes the BCD rotary
switches for frequency selection per the diagrams below, the white digits of the frequency will always be
the same, so there is no rotary selection switch for those digits. The yellow, green, and blue digits are set
via the corresponding rotary switch. Frequencies selected outside the operating frequency of the
transmitter will default to closest functional frequency.
!
!
!
Pre-set Mode, selected when the two 10-position (BCD, 0-9) switches are set to zero and the 16-position
(binary, 0-F) is set to any position 1-F, allows local selection among 15 pre-set configurations. The VST1
transmitter ships from the factory with the 15 pre-sets configured with all options “ON” and set to their
max settings with the frequencies set per the table below. Pre-sets may be changed utilizing
HyperTerminal or other devices connected to the communications port. Pre-sets are reprogrammable
using Remote Mode, selected when all three rotary switches are set to zero. “Remote Only” VST1
transmitters have no rotary switches installed.
Remote Configuration Mode allows you to program your products Preset Configuration Mode or control
the product real time via the communication port (pins 6-9 on the MDM-9S power mating connector). See
the Mechanical Drawing and Connector Pin-Outs of the applicable product.
To set the Transmitter or Receiver to Remote Configuration Mode, all three rotary BCD switches must be
in the “0” position. See the ICD for details on programming your product.
