CONNECTIONS
CONNECTIONS
All connections to the AD1202 Coax Controller are made on
the unit's rear panel, illustrated in Figure 2. Typical AD1202
connections with other AD units are illustrated in the Typical
System Connections section at the end of this manual.
Camera Video Inputs
The AD1202 provides four video input connections on the rear
panel for video signals from color or black and white video
sources. All inputs must be EIA/NTSC (CCIR/PAL) 1 Vp-p
composite video signals. These connectors also transmit coax
control code (camera pan/tilt/lens/preset/aux commands) to the
camera Receiver.
Connect the desired video input sources to the upper BNC
connectors, labeled 1 through 4. For coax control of the
camera, connect coax camera Receivers to these connectors.
The termination of each video input may be selected as
terminated (75 ohms) or unterminated (Hi-Z) via a rear panel
DIP switch (see SETUP, page 7). If a video input is set as
unterminated, that input must be looped to a terminated video
device using the lower BNC connector (see Looping Video
Outputs, next paragraph).
Notes: Use good grade, 75-ohm, RG-59U video cable
with BNC connectors for all video connections.
If the video source is incorrectly unterminated or
double terminated, coax control will not function
properly
Looping Video Outputs
The AD1202 provides a passive looping output for each
camera video input via the lower BNC connectors 1 through 4.
Connect each output as desired to the video input of an
EIA/NTSC (CCIR/PAL) compatible video device.
• If a looping output is connected to another video device,
terminate the video line in 75 ohms at the last device on the
line, and set the termination of the respective camera channel
to Hi-Z via the Termination DIP switch (see SETUP, page
7).

• If any video input is not connected for looping output,
terminate the respective camera channel in 75 ohms via the
Termination DIP switch (see SETUP, page 7).
Monitor Video Output
The BNC connector labeled MON provides a video output for
viewing the selected camera video input. This video output is
a 1 Vp-p, composite video signal.
Connect this output to the video input of an EIA/NTSC
(CCIR/PAL) compatible color or monochrome video monitor.
Terminate this output line in 75 ohms.
Note: Use good grade, 75-ohm, RG-59U video cable with
BNC connectors for all video connections.
