RS232 Interface Setting
You can remotely control the DP700 series power supply via the RS232 interface. Use
the 9-pin RS232 cable (female-to-female, straight) to connect the RS232 interface to
the PC, and set the interface parameters (such as baud rate, parity, etc.) that match
the PC. Then, you can remotely control the instrument.
