RS-232 troubleshooting
Here are a few things to check if you are having problems
communicating over the RS- 232 interface. If you need
additional help, refer to the documentation that came with
your computer.
• Verify that the power supply and your computer are
configured for the same baud rate, parity, and number of
data bits. Make sure that your computer is set up for one
start bit and two stop bits (these values are fixed on the
power supply).
• Make sure to execute the SYSTem:REMote command to
place the power supply in the remote mode.
• Verify that you have connected the correct interface cable
and adapters. Even if the cable has the proper connectors
for your system, the internal wiring may be incorrect. The
Keysight 34398A Cable Kit can be used to connect the
power supply to most computers or terminals.
• Verify that you have connected the interface cable to the
correct serial port on your computer (COM1, COM2, etc).
