shipment or appears damaged, contact AMP with detailed description of problem.
5.2. 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, 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). 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 CDT1 wiring diagram.
Configure the transmitter as instructed in Section 6.2. 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 (as applicable) is present, refer to Section 7.2 for troubleshooting instructions.
5.3. 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).
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

AMN-CD-C 8
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 for a complete wiring diagram.
Configure the receiver as instructed in Section 6.2.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 is present, refer to Section 7.2 for troubleshooting
instructions.

AMN-CD-C 11
6.3. Camera Supply Output(s)
CDT1 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.
6.4. Monitor Supply Output(s):
CDR1 Receivers offer a +12 Vdc a Monitor Supply Output. The output current limit on either supply is
0.5A. The Monitor Supply Output is only active when DC power is applied to the receiver.
6.5. Audio Output(s) (receivers only)
CDR1 Series Receivers, when equipped for audio, offer dual buffered audio outputs.
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.
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.
6.6. Signal Strength Meters (receivers only)
CDR1 Series Receivers are standard equipped with dual Signal Strength Meters mounted to 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

AMN-CD-C 12
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 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.
6.7. Mating Connectors
The CD 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 and/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.
6.8. Use of Heat Sink
CDT1 Transmitters 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 SNK4030-S07B0 heat sink for
use with the CDT1 transmitter.

AMN-CD-C 13
CD 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.
6.9. 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 6.2. To assure optimum performance, the user
should be familiar with the camera, monitor, microphone, and speaker/headphones used with this video
system.
6.10. Shut Down
If the transmitter 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.
7. MAINTENANCE INSTRUCTIONS
7.1. 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.
7.2. Troubleshooting
To avoid poor performance, ensure all mating connectors are tightly fastened, clean, and have no pins
bent or damaged.
Verify configuration of the transmitter and receiver (refer to Section 6.2). 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 transmitter, 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 transmitter and/or receiver, reverse the connections between the
DC voltage supply and DC Power Cable, and reconnect the DC Power Cable.
If all connections are adequate, the transmitter and receiver are correctly configured, and DC voltage is
correctly applied, check the video camera, monitor, video cables, 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. If you still have no audio, check your headphones or audio input using an alternate audio source,
such as an MP3 player. 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.
