the USB.
The power supply USB488 interface functions are described as follows:

RS232 Pins of Plug
The computer and the power supply must be configured for the same
baud rate, parity, number of data bits, and flow control options. Note that
the power supply is configured for 1 start bit and 1 stop bit (these values
are fixed).
The correct interface cables or adapters must be used, as described
under RS-232 Connector. Note that even if the cable has the proper
connectors for your system, the internal wiring may be incorrect.
The interface cable must be connected to the correct serial port on your
computer (COM1, COM2,etc.).
