Precautions

The controller is an indispensable device in the integrated video conferencing system, providing full control of all front-end cameras, pan/tilt and motorized lenses. There are usually many numeric keys and function keys on the controller. The numeric keys are used to select the camera or decoder address, and the function keys are used to perform various control operations on the selected front-end device. An LCD liquid crystal display is provided on the control keyboard for displaying control commands or working states of various monitoring programs in the system. One system use one controller for remote control of the entire video conferencing system.

3. Parameter Setting and Query

3.1 PTZ Setup

E.g. With address code 28, steps to change to Pelco-P protocol and baud rate to 9600 are as follows: Press【SETUP】button for 3 seconds under normal working mode, it displays as follows:

Then press 【ENTER】,there will be a 1sec beep sound when setting done. Press【ESC】 3 times to back to normal working mode.

Note: Steps to set all devices to be with same protocol and baud rate are as follows:

Enter into the setup page and choose the corresponding protocol and baud rate. Then all devices within 0-255 addresses are set with the same protocol and baud rate.

3.2 System Setup

System setup includes: password setting, Restore factory setting, Indicate sound switch setting, Keyboard ID and Keyboard lock switch setting.

Here shows the steps to restore factory setting and set keyboard lock switch.

3.2.1 Password Setting

Press【SETUP】button for 3 seconds under working mode, it displays as follows :

Then input the new password again,press【ENTER】,there will be a 1sec beep sound when setting done. Press【ESC】twice to back to normal working mode.

3.2.2 Restore Factory Setting

Connection with surveillance dome camera

Connection with video conference camera

  1. control output:connect camera RS485+ with keyboard Ta, RS485- with Tb.
  2. Deputy control device:either RS485 output from DVR or keyboard is available.
4.2 Connection Analysis
4.2.1 connection between keyboard and camera

With RS422 bus connection way, the keyboard third pin (Ra) is connected with the camera third pin TXD IN- , the keyboard fourth pin (Rb) with the camera fourth pin TXD IN+ , the keyboard first pin(Ta ) with the camera first pin RXD IN-, the keyboard second pin (Tb)with the camera second pin RXD IN +.

The camera can be controlled by any connection way mentioned above.

4.2.2 Connection between cameras

With the RS422 bus cascade connection, the output of camera 1 is connected with the input of camera 2, and the output of camera 2 is connected with the input of camera 3, and so on so forth. As shown below:

The RS232 cascade connection way is almost the same as that of RS422. The output of camera 1 is connected with the input of camera 2, the output of camera 2 is connected with the input of camera 3, and so on so forth.

5. Appendix

5.1 RS485 bus introduction:

RS485 bus, RS is the abbreviation of English “recommended standard”, 485 is the identification number. The RS485 serial bus is widely used in applications where the communication distance ranges between dozens of meters to 1km more. RS485 uses balanced transmitting and split receiving, so it has the ability to reject common mode interference. In addition to the high sensitivity of the bus transceiver, it can detect voltages as low as 200mV, so the transmitted signal can be recovered beyond the kilometers away. As RS485 adopts half-duplex working mode, and only one point is allowed to be under sending status any time, the transmitting circuit must be controlled by the enable signal. RS485 is very convenient for multi-point interconnection, which help save many signal lines. RS485 can be used to make a distributed system, which allows up to 128 drivers and 128 receivers to be connected in parallel, depending on the chip used by the driver and receiver, and the bus drive capability is limited by the weakest one. However, in practical applications we can extend it with the RS485 distributor

5.2 Transmission distance:

When a 0.56mm (24AWG) twisted pair cable is used as the communication cable,the theoretical value pf the maximum transmission distance varies with different baud rate: 1800 meters can be transmitted when the baud rate is 2400 bps, and 600 meters under 19200 bps. When using a thinner communication cable, or using the product in an environment with strong electromagnetic interference, or when too many devices are connected with the bus, the maximum transmission distance will be shortened accordingly, or the maximum distance is longer.

5.3 Connection method and terminating resistor

The RS485 industrial bus standard requires daisy chain connection between devices. The two ends must be connected with a 120Ω termination resistor. The two balance distances must be within 7m.

5.4 Problems in Actual Application

The star link mode will always be used in actual constructions, requiring the terminating resistor to be linked with the two devices in the farthest distance. But it does not meet the requirements of the RS485 industry standards. When the distance between each device are too long, signal reflection and anti-interference ability reducing would frequently happen, which will decrease the reliability of the control signal. It means the camera will not be under control or under control intermittently. In this case, the application of RS485 distributor is recommended, which can effectively convert the star link mode to one qualified by the RS485 industry standards. It will help avoid problems and improve the communication reliability
