Serial Cable
Connect the serial COM port of your PC and the 600 Series Switch using a
normal null modem cable (or a straight through cable with a null modem
adapter). You will require a cable with a 9-pin or 25-pin sub-D female
connector for the PC end, and a 9-pin female sub-D connector for the
608MFX end.
The following table shows the pin-out and the connections for both types of
cable:
