通信コネクタ
(3) Configuration
For connecting only one unit
For connecting multiple units
Remarks
When a single host computer controls multiple units, register device No. for each device. Set the
device No. on the Basic setting screen. Regarding the internal resistance use setting, set the
terminator of communication line to ON. (Refer to “4. (5) Basic Setting Screen.”)
Do not set the same device No. In the one-way communication mode, perform setting so that
multiple units may not transmit data at the same time. Otherwise, data collision will be caused to
the communication line, resulting in an abnormal operation.
The RS-232C/RS-485 conversion cable and connection cable are not attached to the welding
power supply. Please prepare them by the customer.
