*1: The ground wire is connected to the earth bar.
*2: The ground wire is connected to the earth terminal on site.
*3: Two communication converters are required for 2ch.
*4: (a) shows cable connection of RS-232C communication.
Please refer to the following for flow control setting.
RS control: None, DR check: YES (Recommended), CD check: None
If the instrument to be connected accepts NULL modem-type connection, wiring (b) is also applicable.
