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

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

Camera selection is controlled by pin 21 (External Unit) on the

EXTERNAL connector (see CONNECTIONS, page 3).

Coax Controller (Stand-Alone)

To enable manual (front panel) camera selection, leave pin

21 on the EXTERNAL connector open.

In this mode, the front panel Channel Select buttons select a

camera input for control (see Manual Camera Selection,

page 8).

Control Follower (Used in External Switcher)

To enable External camera selection (from a compatible

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

the rear panel) must be grounded..

The front panel controls must be enabled for camera

programming (see Programming Blocking, page 5).

To program all four camera select buttons for a switcher

camera number:

1. Press the front panel PGM button on the AD1202.

The PGM LED illuminates steadily, and the Channel Select

button 1 LED flashes repeatedly.

2. Press the desired camera select button on the switcher. The

switcher should indicate the selected camera. (Refer to the

appropriate switcher installation manual for the camera

3. Confirm that the AD1202 Channel Select button LED and

the switcher selection indicate the desired choice. (Either

selection may be changed prior to the next step.)

4. Press the front panel SEL button. This accepts the choices

and programs the AD1202 external camera selection to

respond to the switcher camera selection.

The flashing Channel Select LED advances to the next

sequential Channel Select button to permit further

programming.

5. To program the remaining camera select buttons repeat

steps 2 through 4. After the fourth camera select button has

been programmed the first LED above the first camera

select button will again begin to flash. If all the camera

select buttons have been properly programmed, simply exit

the programming mode.

6. To exit programming mode, press the PGM button. The

PGM LED turns off and the Channel Select LED’s indicate

the channel selected prior to the start of programming.

Note: All programming of the select buttons will be held in

4. Confirm that the AD1202 Channel Select button LED and

the switcher selection indicate the desired choice. (Either

selection may be changed prior to the next step.)

Note: Do not program two different AD1202 buttons to the

same switcher camera number. If two buttons are

programmed for the same camera number the

AD1202 selects the lower numbered button for that

camera, and the other button is ignored.

5. Press the front panel SEL button. This accepts the choices

and programs the AD1202 external camera selection to

respond to the switcher camera selection.

The flashing Channel Select LED advances to the next

sequential Channel Select button to permit further

programming.

6. To program another channel select button repeat the above

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

programming (see Programming Blocking, page 5).

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.

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.
