B.2.2 Device Address
The device address is the address of the RC-1160/-1260 which is designated to receive a transmitted command,
or which is responding to a command.
Valid device addresses are 1 to 3 characters long, and in the range of 1 to 255. Address 0 is reserved as a global
address which simultaneously addresses all devices on a given communications link. Devices do not
acknowledge global commands.
Each RC-1160/-1260 which is connected to a common remote communications link must be assigned its own
unique address. Addresses are software selectable at the RC-1160/1260, and must be in the range of 1 to 255.
