4.4 Control Protocol and Baud Rate
Control protocol and baud rate must be set correctly in the dome camera in order to establish proper control communication between the camera and control device. Be sure that the same protocol and baud rate must be implemented in control device, too.
3 types of protocol and 3 levels of baud rate are provided by this speed dome, through an
DS 1
1.
2.Bit 1 and 2 are for baud rate setup
3.Bit 3, 4 and 5 are for protocol selection
4.Bit 6 is reserved future use
5.Bit 7 is for firmware upgrade
6.Bit 8 is for cooling fan on / off switching
First, installer needs to choose a communication protocol with bit number 3, 4 and 5. Watch that the same protocol is chosen for speed dome and controller. The following table shows the three protocols provided in this speed dome.
Check what are available in the controller before choosing the protocol.3 |
