Combination Connection
5.6.2 Assigning IDs
When connection is complete, assign an ID to each unit in the system. This assignment is made on your PC.
Commands: IDC (ID CLEAR) clearing an assigned ID
IDS (ID SET) assigning an ID
IDS is valid only when no ID has been assigned yet. The lowest ID is assigned to the unit directly connected
to the PC, the next higher ID number to the second unit, and so on.
Example: In the case of four connected units (when assigning IDs for the first time from your PC):
Issuing commands in the order shown above assigns IDs to the units in your system. The units should be connected by
combination cables, as shown on the previous page. Once an ID is assigned to a unit, the unit receives only those
commands bearing that ID. When issuing a command to a unit, attach the appropriate ID at the beginning of the
command.
For IDs, you may use numbers from 0 to 9 and letters A to F (case-insensitive).
Asterisks (*) may be used as in the following examples:
**IDC: Clears all assigned IDs.
*1AJY: Places all units having a second ID digit of 1 into adjustment mode.
2*IN1: Switches the function of all units with a first ID digit of 2 to INPUT 1.
Cautions about ID Assignment
Clearing an ID for any unit removes all following units from control from the computer. Issuing an <**IDC> command
removes all units from control except the first unit (the unit having ID 11 in the illustration above). In this case, issuing
a command of 11 IDS makes the second unit controllable from the computer. That is, assigning an ID to a unit makes
it possible to control the following connected unit.
