To change the broadcast address of an already existing broadcast group, simply send a
rs_485_bc_addr
command over the broadcast channel.
7.5 rs485_bc_master <address>
This command enables the broadcast master mode on the camera with the given device
address. If the command is transmitted as a get command (without an argument) it will not
reply with the broadcast master address, but with a flag (0 or 1) that indicates whether this
camera currently is the broadcast master or not.
Transmitting a negative address will always disable the broadcast master mode.

The functionality is explained in the following example:
Two cameras are connected to the same RS485 bus. Camera 1 has the device address 1
and broadcast address 0, camera two has device address 2 and broadcast address 0. To
enable broadcast master mode on camera 1 and disable it on camera 2 send the following
command using the broadcast channel:
0 rs485_bc_master 1
Where 0 is the broadcast address of both cameras and 1 is the device address of the new
broadcast master. You will not receive an “OK” message for this command, but all
following commands that are send over the broadcast channel will be answered by camera
1.
Note: If the commands are not transmitted over the broadcast channel, it might happen
that multiple broadcast masters exist in the system.
To disable broadcast master mode on all cameras in the broadcast group send:
0 rs485_bc_master -1
7.6 rs485_term <flag>
Enables or disables the internal termination of the RS485 interface.
