Pelco-P and Pelco-D code merger, PTZ control via 2 keyboards simultaneusly, Video matrix switcher, PTZ protocol integration, mixing PTZ data. EW-Pelco-Merger, RS-485, telemetry, Pelco code protocol
EW-Pelco-Merger is device dedicated to systems of PTZ cameras, which should be control by using two keybords. By using the Merger code the operator can control two PTZ cameras without Video matrix.
It has 2 ports RS-485, which work as inputs (to connect PTZ keyboard) and one RS-485 output, which communicate composite code to PTZ cameras.





Data mixer of Pelco protocol EW-Pelco-merger
Multiplex receiving and sending of data
Special algorithm, which protect from loss important command of Pelco code, in big sheer volume. Automatic filtered of unnecessary packages and sequential sending of data in order to minimize delays and ensure smooth of camera control.

Dual buffering of data
It’s protect from sending replayed of data in big sheer volume and provides transmission of important commands – beginning and end of movement, pattern, etc.

2 fold increase of RS-485 interface
Devices by using separate RS-485 drivers, may extend the length of bus between PTZ keyboards and cameras.

2 ports with independently adjustable transmission rate
Input port No1 and output port have always the same transmission rate. Input port No2 can have set a different transmission rate, which allows to increasing of universality of device and enables to use keyboards of different manufacturers.

Automatic detection of protocol mode.
The Merger automatic detect Pelco-P and Pelco-D protocols and transmit data in unchanging form to RS-485 output. It’s possible of simultaneous transmission of two different protocols in this same network without mutual interference.


Merger Pelco-P
Control simultaneous of two independent cameras



Detection of control by the same camera
When camera is controled by one operator, second operator has automatic lock of access to the same camera, which protected the  system from collisions and unspecified control. When second operator ended control of camera, the first operator can take the same camera after 5 or 30 seconds(time adjustable). The opposite situation is in moment, when first operator take control of camera as a first (Port 2).


Function of priority for Port 1
Standard input ports 1 and 2 have the same access priority for the same camera. After switching on priority function, the first operator(Port 1) always be able to take camera controlled before the second operator (Port 2). The second operator must wait, until the first operator ended control or will choose other camera to control.


Code Merger of Pelco-D protocol
Automatic lock access to camera, which is supported by other operator.
