For a Windows computer, insert the 8-pin mini-DIN end of the interface cable into 
the 9-pin DB9 Connector cable adapter. Insert the 9-pin end into the COM1 or 
COM2 port on the computer and tighten the screws. If the available port on your 
computer is 25-pin, you must use the 8-pin-to-25-pin adapter.

For a Mac OS computer, connect the 8-pin mini-DIN plug directly into the serial port 
of the computer.
