Some protocols and the states of the coding switches of normal baud rate of these protocols show as follows:
13.4 Communication Baudrate Setup.
As shown in Figure 12, SW2 is used to set the protocol of communication and the baud rate used by the dome camera. DIP-6 and
DIP-5 of SW2 are used to select the baud rate of communication and 4 different baud rates can be selected in maximum. If the
controller adopts non-standard baud rate, you can adjust it to be identical with that of the main machine as per the following table.
Baudrate
2400bps
4800bps
9600bps
19200bps
13.5 Selection of the Terminal Resistor of the Dome Camera.
As shown in Figure 16, JP1 is the select switch of the 120
the dome camera at the farthest end can be connected, while the terminal resistors of other devices should be opened.
