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

Connection Analysis

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

Keyboard/CAMERA

• Ra: TXD INRb: TXD IN+
• Ta: RXD INTb: RXD IN+

With RS232 connection way, the keyboard (10pin connecting terminal) first pin RXD is connected with the third pin TXD of camera RS232 port, the keyboard second pin TXD with the camera fifth RXD, the keyboard third GND with the camera forth pin GND. (It is also available to connect camera with the standard RS232 port on the keyboard.)

Keyboard/CAMERA

• RXD: TXD
• TXD: RXD
• GND: RXD

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

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.

Appendix

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 can 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 kilometres 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

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.

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.

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 RS485 industry standards. When the distance between each device is too short, 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.

Troubleshooting

whether the RS485 line is short-circuited when power off.
2.check the correspondence of camera protocol and baud rate settings with those ofSDC-TR01| Step 1: Check whether the current protocol and baud rate are correspondent. Step 2: Restore the SDC-TR01default settingsand then reset it.
3.Check whether the PTZ indicator light flickering when control.| Step 1: If the PTZ indicator light flickers when control, then there is no problem with SDC-TR01.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 cannot be controlled by SDC-TR01| 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 ofSDC-TR01| Check whether the current protocol and baud rate of each address are correspondent. Please refer to camera user manual.
Not all cameras can be controlled by SDC-TR01.| 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 distributor to the star connection
---|---|---
Some cameras 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.
Button silent| Enter the system settings and turn on the button sound.
