DESCRIPTION
The AD1202 MCS Coax Controller is a compact Pan/Tilt,
Lens, Preset Scene, and Auxiliary controller for four color or
monochrome cameras. The AD1202 provides coax control of
four cameras via the video line connection to the camera site.
Additionally, AD Manchester Control Code outputs are
available for control of non-coax camera Receivers.
Each camera can be individually selected and controlled from
the AD1202 front panel. The selected camera’s video input is
displayed via the rear panel Monitor output. Pushbutton
control is provided for camera pan/tilt, lens zoom/focus/iris,
preset scene, and auxiliary functions.
The AD1202 responds to external alarm contact closures by
automatically calling the alarmed camera to the monitor output
and calling preset 1 of that alarmed input. Separate alarm
inputs are provided for each camera input. The AD1202 also
provides a pulse output when an alarm is received at any of the
four alarm inputs. This pulse can be used to activate an
external device such as a VCR.
Camera preset scenes at suitably equipped camera sites can be
controlled by the AD1202, using AD1640 and AD1680 Series
Receivers. The AD1202 can program and recall any of the
first four presets (1 - 4) for one of these Receivers.
Looping video outputs allow the AD1202 to operate as a
control follower with MCS-compatible American Dynamics
switchers. The AD1202 can respond to camera selections
made by the switcher to allow coax control of the requested
camera. The AD1202 can be programmed to control any four
cameras of the switcher. Four AD1202 Controllers can be
cascaded to a single MCS switcher to control sixteen cameras.
A security lockout feature disables front panel programming
controls. This capability prevents inadvertent changes to
camera programming.
A built-in test procedure provides verification of AD1202 front
panel controls and indicators.
FEATURES
• Individual control of four cameras via coax video line or
separate AD Manchester Control Code line
• Selectable coax control code for variable speed (Enhanced
Code) or fixed speed (Standard Code).
• Dual-speed pan/tilt control, full lens zoom, focus, and iris
control, plus control of four auxiliaries
• Monitor output of selected or alarmed camera video input

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.

ALARM INPUTS
The EXTERNAL connector provides four Alarm Input pins
(pins 11 - 14) for external alarm contacts, one for each
camera input. The Alarm Input number refers to the
associated camera input number. The AD1202 responds to
normally open (NO) contact closures from external alarm
devices (see page 9 for Alarm Response).
1. Connect the external alarm contact signal line to the
appropriate Alarm Input (pin 11 - 14).
2. Connect the remaining side of each alarm contact to
Ground (pin 16, 22, or 24).
Alarm contact closures to ground must have a resistance of
500 ohms or less; alarm opens must have a resistance of
100,000 ohms or more.
Note: If alarm contacts are installed and the AD1202 is
connected to a switcher, connect each alarm contact
in parallel to both the switcher and the AD1202
alarm inputs. See page C-5 for an illustration of
alarm connections to both the AD1202 and a
switcher.
ALARM OUTPUT
The AD1202 provides an open collector output pulse on pin
15, Alarm Out, when an alarm input is received. The pulse
is held active until the alarm input clears, with a minimum of
five seconds duration. This pulse can be used to activate an
external device such as a VCR.
1. Connect Alarm Out (pin 15) to the external device.
2. Connect the remaining side of the device control signal
to Ground (pin 16, 22, or 24).
CAMERA ADDRESS INPUT
The binary input, BIN IN (pins 17 - 20), accepts a binary
camera number input from an MCS-compatible AD
switcher. These pins allow the AD1202 to operate as a
controller follower, permitting external selection of a camera
by the connected switcher (see Camera Selection, page 6).
Connect the camera binary address pins from the switcher to
the AD1202 BIN IN pins.
1. Connect the switcher camera address bit 0 to the BIN IN
bit 0 (pin 17).
2. Connect the switcher camera address bit 1 to the BIN IN
bit 1 (pin 18).
3. Connect the switcher camera address bit 2 to the BIN
IN bit 2 (pin 19).
4. Connect the switcher camera address bit 3 to the BIN
IN bit 3 (pin 20).
5. Connect a ground pin from the switcher to Ground (pin
16, 22, or 24).
CHANNEL SELECT OUTPUTS
The Channel SEL pins (pins 1 - 4) provide individual logic
level outputs for each camera channel. Each Channel SEL
pin is active (logic high) when the respective camera channel
is selected (see Camera Selection, page 6). These signals
can be used to control an external device.
1. Connect the applicable Channel SEL output (pin 1 - 4)
to the device desired.
2. Connect the remaining side of the device control signal
to Ground (pin 16, 22, or 24).
AD1202 CONNECTIONS
3
Use NEC Class 2 wiring only for all EXTERNAL
connector pin connections. The wiring should also
conform to all local codes.
!
Note
If any address bit inputs are not provided, connect
those AD1202 pins to Ground (pin 16,22, or 24).
EXTERNAL Connector (Continued)
AD MANCHESTER CONTROL CODE OUTPUTS
The EXTERNAL connector provides two sets of AD
Manchester Control Code lines (Code 1 - pins 5 - 7, and
Code 2 - pins 8 - 10) for output of camera control commands
(camera pan/tilt/lens/preset/aux) to AD Manchester Control
Code units, such as camera site Receivers.
1. Connect the Black Code wire to the Code Black pin of
the EXTERNAL connector (pin 5 or 8).
2. Connect the White Code wire to the Code White pin of
the EXTERNAL connector (pin 6 or 9).
3. Connect the cable shield to the Code Shield pin of the
EXTERNAL connector (pin 7 or 10).
Use 18 AWG, shielded, 2-wire cable, Belden 8760 or
equivalent for code line connections. The maximum cable
length is 5000 feet.
Each code line can accommodate a maximum of three code-
controlled units in a “Daisy Chain” configuration of less
than 5000 feet, as illustrated in Figure 3. Terminate only the
last unit on the code line in 120 ohms.
If additional equipment is required on a code line, or if
longer distances are involved, Code Distribution Units must
be used, as illustrated in Figure 4. The AD1691 Manchester
Control Code Distributor provides 64 code line outputs from
a single code line input. Terminate the last unit on each
code line in 120 ohms.
CONTROL PINS
The EXTERNAL connector provides two control pins.
External Unit (pin 21)
This pin enables camera selection to be performed by the
front panel either as a coax controller (manual) or as an
external switcher as a control follower. Refer to the SETUP
instructions for Camera Selection, page 6.
• For operation as a coax controller, leave pin 21 open
(unconnected).
• For operation as a control follower, connect pin 21 to
ground (pin 16, 22, or 24).
Code Select (pin 23)
This pin selects the type of coax control code (Standard or
Enhanced UTC) transmitted via the camera video input
lines. Refer to the SETUP instructions for Coax Code
Selection, page 7.
• To transmit Enhanced UTC code via the camera video
input lines, leave pin 23 open (unconnected).
• To transmit Standard UTC coax code via the camera video
input lines, connect pin 23 to ground (pin 16, 22, or 24).
Note: Do not mix Standard Only and Enhanced Only receiver
drivers. The 1202 can only send one code style.
Power Connection
All 120 V units are supplied with appropriate pendant 3-wire
cords and plugs for mating to the primary power source. All
230 V units are supplied with a Euro-style IEC 320 type inlet.
A suitable detachable cord should be connected between the
IEC inlet and the power source. The cord should conform to all
national and local use code requirements.
AD1202 - 120VAC, 50/60 Hz
ADS1202X - 230VAC, 50/60 Hz
There is no power switch on the AD1202 or ADS1202X. Power is
applied to the unit when the cord is plugged into the power source.

AD switcher), connect pin 21 to Ground (pin 16, 22, or 24)
on the EXTERNAL connector.
When set for this mode, camera selection is provided by the
switcher EXTERNAL connection (BIN IN pins) only; the
front panel Channel Select buttons cannot select a camera.
External camera selection can be programmed for any four
camera numbers selected by a compatible AD switcher (see
Camera Programming).
Camera Programming
When External camera selection is enabled, AD1202 camera
selection can be programmed to respond to (follow) any four
camera numbers selected by a compatible AD switcher.
The AD1202 is factory set for operation with input number 1
set to follow switcher camera 1, input 2 for camera 2, input 3
for camera 3, and input 4 for camera 4. Each AD1202 input
can be programmed to follow any of 16 camera numbers.
Note: To program the AD1202 camera inputs, the camera
address binary output from the switcher must be
connected to the AD1202 BIN IN pins (see page 3)
and pin 22 on the EXTERNAL connector (located on

steps from step 2.
Note: All programming of the select buttons will be held in
non-volatile memory and will not need to be re-
programmed upon a power failure.
Preset Scene Programming
Camera pan/tilt and lens units with preset capability can be
programmed to move automatically to preset scenes using
AD1640/1680 Series Receivers. A suitably equipped camera
site Receiver can store 72 preset scenes for subsequent recall.
The AD1202 can program and call any of the first four preset
scenes (1 - 4). Preset scenes are stored at the respective
camera Receiver, not in the AD1202.
Note: The front panel controls must be enabled for preset

To program and store a preset scene:
1. Select the desired camera by pressing the corresponding
front panel Channel Select button.
2. Using the AD1202 front panel controls, adjust the camera
pan, tilt, zoom, iris, and focus to obtain the desired scene, as
viewed on the MON video output.
3. Press the front panel PRESET SET button.
The SET LED illuminates.
4. Enter the desired preset number (1 - 4) by pressing the
corresponding Channel Select button.
The Channel Select LED illuminates briefly to confirm the
selection, then both the SET and Channel Select LED’s turn
off, indicating that the preset scene is programmed.
If no Channel Select button is pressed within five seconds
after the SET button is pressed, the function is cancelled
and the SET LED turns off.
Programmed preset scenes 1 - 4 may be called by front panel
commands any time the associated camera is under control of
the AD1202 (see Calling a Preset Scene, page 9).
If Preset Scene 1 is programmed for a camera by the above
AD1202 procedure only, that preset is automatically called by
the AD1202 when an alarm is received on the Alarm Input
associated with that camera (see Alarm Response, page 10).
Note: All presets are held in non-volatile memory and will
not need to be reset upon a power failure.
Video Input Termination
The termination of each video input to the AD1202 may be
individually selected as terminated (75 ohms) or unterminated
(Hi-Z) via a rear panel DIP switch, labeled TERM (see Figure
6). Four separate switches are provided, labeled 1 to 4, one for
each corresponding video input channel. The factory default
setting of all inputs is Terminated, 75 ohms.
To change the termination of any video input, push the
associated slide switch (switch 1 for input channel 1, etc.) to
the appropriate position: up for terminated in 75 ohms, or
down for unterminated at Hi-Z.

If an input is set as unterminated, that input must be looped to
a terminated video device using the lower BNC connector (see
Looping Video Outputs, page 2).
Coax Code Selection
The AD1202 provides two different types of code output for
coax control to a camera Receiver: Standard or Enhanced
UTC code. The selected code is transmitted to the camera
Receiver, via the video coax connection, encoded onto video
signal line 17 during the vertical interval.
Select the type of transmitted code (Standard or Enhanced
UTC) by pin 23 (Code Select) on the EXTERNAL connector
(see page 3).
To Transmit Enhanced UTC code, leave pin 23 on the
EXTERNAL connector open.
To Transmit Standard UTC code, connect pin 23 to Ground
(pin 16, 22, or 24) on the EXTERNAL connector.
OPERATION
Controlling Camera Site Functions
Camera site control functions (pan/tilt, motorized lens, preset
scenes, and auxiliary actions) are available using the AD1202
front panel buttons (Figure 7) after a camera input is selected.
Select a camera either manually from the AD1202 front panel,
or externally from a compatible AD switcher, depending on the
Camera Selection mode.
Note: Only one method of selection is enabled at one time.
See Camera Selection, page 6, to set the AD1202
camera selection method.
CAMERA SELECTION AS A COAX CONTROLLER
When the AD1202 is set as a coax controller, select a camera
from the AD1202 front panel by pressing the corresponding
Channel Select button for the desired camera input number
(1 - 4).
CAMERA SELECTION AS A CONTROL FOLLOWER
When the AD1202 is set as a control follower, the AD1202
automatically selects a camera in response to an external
switcher camera selection.
A compatible AD switcher must be connected to the
AD1202 EXTERNAL connector binary inputs (BIN IN
pins) (see CONNECTIONS, page 3). When a camera is
selected by the switcher, the camera address is provided via
the BIN IN pins and the AD1202 automatically selects the
camera input programmed for this address.
The monitor output of the switch should be used to view
the selected inputs.
Note: The AD1202 must be programmed for the camera
numbers used by the connected switcher (see
Camera Programming, page 6).
Camera Pan/Tilt Control
Camera pan/tilt units are controlled by the four AD1202 front
panel arrow buttons.
To control camera Pan and Tilt:
1. Select the desired camera (manual or external selection).
2. Press and hold the front panel pan/tilt arrow button in the
desired direction.
For control of variable-speed pan/tilt units, camera
movement speed may be selected via the pan/tilt buttons.
• Press the outer side of each button (larger arrow) for fast
movement.
• Press the inside of each button (smaller arrow) for slow
movement.
Note: To obtain diagonal camera movement, press two of the
arrow buttons simultaneously (e.g., left and up, right and
up, etc.). Be careful that you press each key either over
the small arrow or the large arrow. Pressing all four key
switches (two key switches on each key) simultaneously
will result in no camera movement on the diagonal.
3. Release the button when the camera is at the desired scene
or view, as shown on the monitor.
Camera Lens Control
Camera motorized lens units are controlled by the AD1202
front panel IRIS, FOCUS, and ZOOM buttons.
To control camera motorized Lens functions:
1. Select the desired camera (manual or external selection).
2. Press and hold the front panel button designating the
desired lens action (Iris OPEN or CLOSE, Focus NEAR or
FAR, Zoom TELE or WIDE).
Note: The available lens control functions depend on the
type of motorized lens installed on the camera (e.g.,
an Auto-Iris lens cannot be controlled by the IRIS
OPEN or CLOSE buttons).
3. Release the button when the camera lens is at the desired
Iris, Focus, or Zoom position.

Calling a Preset Camera Scene
A suitably equipped AD Receiver can store a maximum of 72
preset scenes. The AD1202 can call any of the first four preset
scenes using the front panel PRESET buttons. See Preset
Scene Programming, page 7, to program preset scenes.
To call a preset scene:
1. Select the desired camera (manual or external selection).
2. Press the front panel PRESET CALL button. The CALL
LED illuminates.
3. Press the Channel Select button corresponding to the
desired preset scene number (1 - 4). The Call LED turns
off.
If no Channel Select button is pressed within five seconds,
the function is cancelled.
Note: If a preset is called and no preset scene has been
programmed for that preset number, the camera
movement may be unexpected.
Activating an Auxiliary
The AD1202 can activate any of four auxiliary functions at a
camera site (lights, gates, etc.) using the front panel AUX
ON/OFF buttons. These buttons control either momentary or
latching auxiliary actions. The number and type of auxiliary
functions at a camera site depends on the options installed in
the camera Receiver at the site.
To activate an auxiliary:
1. Select the desired camera (manual or external selection).
2. Press the AUX ON button on the front panel. The AUX
ON LED illuminates.
3. Press and hold the Channel Select button corresponding to
the desired auxiliary number (1 - 4).
4. Release the button when the desired action is achieved. The
AUX ON LED turns off.
• If the auxiliary is a momentary type, the action stops.
• If the auxiliary is a latching type, the action continues
until the auxiliary is deactivated, as described below.
To deactivate a latching auxiliary function:
1. Select the desired camera (manual or external selection).
2. Press the AUX OFF button on the front panel. The AUX
OFF LED illuminates.
3. Press the Channel Select button corresponding to the
desired auxiliary number (1 - 4). The AUX LED turns off.
Alarm Response
There are four alarm inputs on the rear panel EXTERNAL
connector (see page 3). Each alarm input corresponds to one
of the four video input BNC’s on the rear panel. The alarm
inputs can be connected to any device that produces a contact
closure on alarm.
ALARM RECEIPT
The AD1202 detects and responds to external alarms when
there is a contact closure at any alarm input.
1. The camera corresponding to the alarm is selected by the
AD1202. In External camera selection mode, this
selection follows the switcher alarm response selection.
2. If preset scene number 1 has been programmed for this
camera by the AD1202 (see page 7), this preset is called.
If preset 1 was not programmed the preset will not be
called.
3. A pulse is output on the Alarm Out pin (see page 3).
The alarm pulse is held active until the alarm input
clears, with a minimum duration of five seconds.
4. If the AD1202 is in camera selection mode:
The Channel Select button LED corresponding to the
alarm input flashes until the alarm is acknowledged
(see Alarm Acknowledge, below).
If the AD1202 is in camera selection mode:
All active alarms are indicated by the external switcher
connected to the AD1202.
ALARM ACKNOWLEDGE
If the AD1202 is in camera selection mode:
• Press the AD1202 Channel Select button associated with
the flashing LED to acknowledge the alarm. The LED
stops flashing and remains illuminated until a different
channel is selected.
If the AD1202 is in camera selection mode:
• Acknowledge the alarm at the external switcher.
(Refer to the appropriate switcher installation manual for
alarm acknowledge procedures.)
In either mode, the alarm output pulse is reset only after the
alarm input is cleared (contact is reset), with a minimum
pulse duration of five seconds.
AD1202 OPERATION
Note
For proper alarm response when used as a control follower
camera selection mode, all alarm inputs must be connected
in parallel with both the external switcher and the AD1202.
(see page 3)
Appendix
BUILT-IN TEST
The AD1202 has a built-in test procedure that provides a
verification of AD1202 front panel controls.
To operate the built-in test:
1. Remove power from the AD1202, and remove the cover
from the unit.
2. Press the TEST button on the PCB while applying power to
the unit. See Figure A-1 for location of the TEST button.
Each of the front panel LED’s is illuminated in sequence.
This verifies that each LED illuminates properly.
If any LED’s do not illuminate, the unit is not operating
properly.
After the individual LED's have illuminated, continue with
the next step.
3. Press each front panel button, one at a time.
Each time a button is pressed, all ten front panel LED’s will
illuminate simultaneously, signifying that the switch closure
was recognized by the unit.
If the LED’s flash when a button is pressed, one or more
buttons may be shorted and the unit is not operating
properly.
4. Remove power from the unit to exit the test procedure.
If any of the above responses are not as indicated, the unit may
not be operating properly.
Note: An erroneous indication may be noted if the pan/tilt
keys are depressed incorrectly (the LEDs flash). Make
sure you press either one side or the other side of these
keys. Pressing these keys such that the two key switches
underneath are pressed simultaneously will result in
flashing LEDs.
