17
[Multiple units]
Set consecutive ID numbers beginning with "1", which are automatically assigned to the units in setting order.
Notes
• Make connections of the rear panel-mounted RS-485 port before using. (Refer to p. 14 "Connections between
Units.")
• The unit set for ID No. 1 functions as a master unit.
Step 1. Press and hold down the Unit ID Number display key on the unit.
The ID number of the unit is automatically set and will appear and flash on the Memory/Unit ID
Number display.
Step 2. Release the ID number key.
The unit's ID number setting is completed.
Note: The indication of the selected ID number continues to flash on the display even after its setting
completion.
Caution: For the second unit and its subsequent units, the ID number is set when the Master
indicator is extinguished after illuminating for about 1 second. To avoid the duplication of the
ID number, do not make settings of other units during this time.
Step 3. Repeat Steps 1 and 2 above for all units.
7.5.2. Changing the Unit ID Number
Step 1. Press the Memory/Unit ID Number selector key to change the number while holding down the Unit ID
Number display key (the display quickly flashes).
Step 2. Select the desired number and release the ID number display key. The new number is set (the display
continues to flash even after setting completion).
Cautions
• Take care not to assign duplicate Unit ID numbers. If duplicated, the unit number cannot be changed and the
indication of "Id" flashes on the Memory/Unit ID number display. In such cases, perform the ID number
setting again. (Refer to p. 16 "Unit ID number setting.")
• When the Master indicator on two or more units simultaneously light, the function of a single-PC control or
simultaneous pattern switching is disabled. To enable such functions, connect all of the units' RS-485 ports
to permit only the ID No. 1 unit's Master indicator to light.
7.5.3. Unit ID Number confirmation
Pressing the Unit ID Number Display key causes the indication of the set ID number to quickly flash on the
Memory/Unit ID Number display. When multiple DP-0206 units are connected, if the Unit ID Number Display
key on any one of them is pressed, the corresponding ID number will be displayed on each unit.
