5.5.3 Combination Connection

When performing control and adjustment, it is convenient to connect several sets to one PC.
By performing a combination connection and assigning IDs to the sets, it is possible to control and adjust several sets
at the same time or separately.
Connection method:
Connect the sets as shown in the figure below, and perform control and adjustment with the PC.

Note
Only the combination IN terminal or RS-232C terminal can be used at the same time on one set. Connecting them at
the same time could cause erroneous operation or be the cause of trouble, so do not connect them at the same
time. Also, do not connect pair of combination IN terminals or combination OUT terminals. Doing so could cause
trouble.
It is possible to use a general-purpose mini DIN 6-pin (straight) cable for the combination cable.
Note
To output RS-232C signals from the combination OUT terminal, an ID must be assigned.
For details, refer to section, 5.5.4, "ID Assignment (pg. 175)".
