Each monitor can have a specific address e.g. 007 which helps command that monitor individually and will not affect other monitors connected to
a controlling pc.
Address format command
The adressing format command is used for operating multiple monitor sets from a single pc via the RS232 command line. If you set your monitor
address to '000' it will never respond to any addressing command from the pc. If the address from the pc is 'FFF', all monitor sets will execute the
command.
The address format command is defined by one command, one line which starts with 'A' and ends with carriage return (0x0D). An address is
added at the top of a control command.
Example:
Functional execution command: "A001C05" [CR] means the address is 001 and the control command is C05
Status read command: "A001CR0" [CR] means the address is 001 and the command is CR0
The monitor can set its own address in the hotel option (see above). The address range is 000 - 999, the default address will be 000.
The baud rate indicates the unit transfer speed of data from the pc the the monitor sets.
