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 1 start bit and 2 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 HP 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).
