Before you buy this item, please check your PC based DVR system (in the setup)that supports the protocols
(see below protocol list) for Pan Tilt and motorized zoom lens.

1. Product Description

This Decoder is used with keyboard controller and matrix systems to control PAN, TILT, ZOOM,
FUCUS, IRIS and auxialiary functions in survelillance system. Receivers are RS485 or Manchester
communication, it is compatible with multi-protocol.

2. Features

- Built in watch dog function, Multi-protocol setting
- Two auxiliary relays for light, wiper and camera power controlling
- Fully optical isolation, auto reset function in strong reference environment.
- Baud rate options,0-64-256 ID setting
- Static resistant, high voltage and thunder proof design.
- Optional power source provided AC24V, DC12
- AC 24V voltage for pan/tilt unit

3. Technical parameter

- Power Input: 24VAC / 60hz
- Power consumtion: 28 ~ 50W
- Pan/Tilt voltage: AC 24V
- Pan/Tilt drive power consumption: AC 24V / 800mA
- Lens voltage output: 5~ 12V
- Provided power source: AC 24V/500mA, DC 12V /600mA (for camera power)
- Auxiliary relay: 2 NO auxiliary ( AUX1 and AUX2)
- Communication: RS 458, Manchester
- Protocol: multi-protocol setting
- Operating environment : Indoor(-10~70 deg), Outdoor(-40 ~ 85 deg)
- Transmissiion distance: 100 meters

4. Pan/Tilt setting

The Decoder can control Pan/Tilt up, down, left, right movements and auto function.
There are two kinds of voltage optional, AC 110V & AC 24V (Warning: higher voltage
will lead to the fact that Pan/Tilt be damaged)

5. Lens setting

The Decoder can control the IRIS, FOCUS and ZOOM of lens. The lens output voltage can be
varied from 6 to 12 volts DC with a potentiometer. The operator can adjust the speed of lens
via lens power, the voltage is higher then the speed is faster.

6. Auxiliary control

There are 2 auxiliary relay normally oen( AUX1 and AUX2)

7. Protocol

Pelco D, Pelco-P, Panasonic etc.

8. Baud rate

1200, 2400, 4800, 9600

9. ID Address setting up to 63 units.

10. System connections

- Use twist pair cable for correct connection per RS485 communication standard, otherwise
the communication distance will be shorten significantly if using parallel cable.
- The receiver is designed for "star" and "daisy chain" connection, the terminals marked A and
B are RS485 signal output ports which is to connect RS485 devices, connection is not allowed.
- When a lot of receivers need to connect together, a 120-ohm resistor must be connected in
parallel between the terminal marked A and B on the last piece of equipment on the time.
