Device Address
The device address is the address of the KST-2000L 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 0 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.
KST-2000Ls which are connected to a common remote communications link must be
assigned their own unique address. Addresses are software selectable and must be in the
range of 1 to 255.
Notes:
1. 'add' is used to indicate a valid 1 to 3 character device address in the range
between 0 and 255.
2. Global address '*' is reserved for EXTERNAL KEYPAD commands.
