Serial port line to connect between PC and APC Switched Rack PDU? Either we order 1 or how to make it?
Thank you for your inquiry. According to the manual the cable needed is the APC PDU configuration cable, part number: 940-0144. Unfortunately, we could not find a source for this replacement cable and could not find a cable diagram to build one.

This is the relevant portion of the manual:
You can use a local computer to connect to the PDU to access the control
console.
1. Select a serial port at the local computer, and disable any service
which uses that port.
2. Use the configuration cable (940-0144) to connect the selected port
to the serial port on the front panel of the PDU.
3. Run a terminal program (such as HyperTerminal) and configure
the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and
no flow control, and save the changes.
4. Press ENTER to display the User Name prompt.
5. Use apc for the user name and password.
6. See “Control console” on page 11 to finish the configuration
