Serial Commands
Addressing Commands
If the switcher is being used in RS-232 mode (no other devices connected in parallel) there is no
need to assign an address for this unit. If you are using multiple Inline products connected in
parallel to a single serial port using RS-422 or RS-485 communications, you will need to assign
an address for each unit.
The factory default for the unit is no address. The address for the unit must be between 01 and
98. Address 00 is a broadcast address and all units on the buss will perform the action
commanded; however, they will not issue any responses.
To open communications to an addressed device, you must send a [CCxx] command. All other
devices on the buss will ignore commands until addressed.
COMMAND DESCRIPTION
[ADDRxx] Assigns an address to the unit, 01 to 98. Address 99 is reserved for future
products.

[ADDR@] Removes an address from the unit. This is the factory default, and is the
typical way to use the switcher when in the RS-232 mode
