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.

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.

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 more than 1km. 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. RS485 adopts half-duplex working mode, and only one point can be sent at any time, so the transmitting circuit must be controlled by the enable signal. RS485 is very convenient for multi-point interconnection, and many signal lines can be omitted. 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 capability. However, in practical applications we can extend it with the RS485 splitter.

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 thin 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 probably happen during construction
In the actual application, the user often adopts the star link mode. At this time, the terminating resistor must be linked to the two devices in the farthest distance, but since the connection method does not meet the requirements of the RS485 industry standard, the line distance in each device In time, it is easy to generate signal reflection, and the anti-interference ability is reduced, which leads to a decrease in the reliability of the control signal. The reflection phenomenon is that the camera is not controlled or controlled, and the self-operation cannot be stopped. For this situation it is recommended to use the RS485 splitter. It can effectively convert the star link to the connection method specified by the RS485 industry standard, thereby avoiding problems and improving the reliability of communication.

Trouble shootings

Step 1: Whether the RS485 A and B are reversed, Step 2: check whether the RS485 line is short-circuited when power off.

2.check the correspondence of camera protocol and baud rate settings with those of KBD

| Step 1: Check whether the current protocol and baud rate are correspondent.
Step 2: Restore the KBD default settings and then reset it.
3.Check whether the PTZ| Step 1: If the PTZ indicator light
| indicator light flickering when control.| flickers when control, then there is no problem with KBD.
Step 2: If the PTZ indicator light does not flash when control, there is some problem with the RS485 output of the keyboard.
Please return to factory for repairing.

Video conference camera can not be controlled by KBD| ** 1.check the control cable| Make sure a right connection of the control cable.
2.check the correspondence of camera protocol and baud rate settings with those of KBD| Check whether the current protocol and baud rate of each address are correspondent.
Please refer to camera user manual.
Not all camera can be controlled by KBD.| 1.Inspect accessories.| Inspect all connection cables.
2.Check settings.| Check whether the current protocol and baud rate  of each address are correspondent.
3.Probably a problem with star wiring.| Step 1: At the farthest end of RS485, connect an impedance of 120Ω.
Step 2: Add RS485 splitter to the star connection
Some camera rotate at the same time when control.| 1.Inspect camera address setting.| Check if the address codes of the cameras that are moving together are the same, please stagger the address code settings.
(Note:** you need to restart after modifying the dialing switch to take effect)
Forget the locking password| Long press the [SETUP] key to enter the system settings and reset the password, if happened at any time.
