PELCO-D/P to SONY-D70P VISCA code converter
Posted on

The SONY EVI-D70/D100 is a popular mainstream camera in the video conferencing system/conference discussion system. The camera has an 18x/10x optical zoom lens and supports a wide range of high-speed pan/tilt movements (horizontal angle -170°). Up to +170°, maximum horizontal speed 100°/sec, vertical angle -30° to +90°, maximum vertical speed 90°/sec), support for preset operation, widely used for remote shooting in halls, courts, concert halls, etc. application. Thanks to SONY's deep brand influence, excellent imaging results and high-quality structure work, this series of cameras almost occupy more than 50% of the market share of this high-end field. With the continuous expansion of video surveillance systems, products in the security industry and products in the video conferencing industry have gradually penetrated each other. Many customers have proposed to use the security matrix/DVR/direct control keyboard to control the SONY EVI-D70/D100. However, similar to the security industry's PelcoP/D control protocol, the D70/D100's built-in SONY VISCA protocol is also unique in the video conferencing industry, resulting in incompatible versions of the two protocols.

 
one,        SONY-D70P communication introduction

This product mainly solves the problem that the SONY video conference camera cannot be compatible with the surveillance video recorder, matrix and control keyboard system in the monitoring system. The original SONY-D70P communication protocol is a SONY-VISCA proprietary protocol that must be controlled with the SONY-VISCA dedicated control keyboard. In addition to the remote control, the D70P can be controlled by the host computer software through its RS232 communication interface and PC. However, the remote control control distance is within 10 meters, and the RS232 control is only 15 meters. In the system, it is often necessary to centrally control the D70P cameras in each video conference room. In this case, the RS422 communication of the D70P camera is required to achieve remote control, up to 1200 meters. RS422 is connected to TX+ TX-RX+RX- four ports by one 4-core cable. It can be controlled by the main control without returning 2 wires. The D70P can also be controlled, that is, the RS485 communication format controls D70P. It can be passed through the 2-core control line.
 
two,        Set up the connection
Although the SONY EVI-D70/D100 only provides the RS-422 port on the back and does not provide the RS-485 port, we can implement data communication and control devices by simplifying the connection, such as: matrix / DVR / direct control keyboard / DVS RS- The 485 port is connected to the code, the RS-485 port A of the code is connected to the RXD IN- of the D70/D100, and the B is connected to the -RXD IN+ of the D70/D100.
 
three,        Code to use instructions

1. The protocol code converter input is the standard RS485 communication format, and the output is also the standard RS485 communication format.
2, code conversion input automatic identification monitoring industry PELCO-P\\D two protocols, the baud rate can be set internally, the default setting is 2400bit / s.
3. The main control room of the monitoring room can be controlled by the address control code of 0-63. The code can be set internally by the dial switch. The default setting is 01.
4. The code-to-output is a fixed baud rate of 9600 bit/s, the output protocol is fixed SONY-VISCA, and the output address is fixed at number 01.
5. If there are multiple D70P cameras in the system, you need to place a transcoder next to each D70P camera.
6, code conversion has 4 standard RS485 communication port output, and the other 3 channels are reserved. The communication line can be used with one RVVP0.75*2.
7. It is recommended to use hand-in-hand connection for engineering construction wiring, that is, pull a 2-core RVVP0.75*2 communication line into the main control room, and the front-end code is connected and connected.
8, the third switch under the D70P should be dialed to 422 mode, the code-to-output OUT-B is connected to the third pin of the D70P green terminal, and the OUT-A is connected to the fourth pin.
