Serial to ethernet cable: how to connect to device

  • 772

How can I use a serial to ethernet cable to connect to a device: in my case a Hp ProCurve AP?

A serial to USB or serial to serial would have been great but I found this serial to ethernet cable from a Cisco router lying around and I though that I might use it.

Is it possible?

    That cable is not a serial to Ethernet cable. It is a female DB-9 to 8P8C plug serial cable. Cisco uses 8P8C connectors that are the same as copper Ethernet for console access to their equipment. That cable would normally go from 9pin serial on your computer to the router console which is also serial. I'm guessing since you thought it was serial to Ethernet your HP kit has a male 9pin connector on it? If so you will need a 9pin null modem cable with female 9pin connectors on both ends.

  2. The cable needs to be a DB-9 female-to-female serial cable.

    In your terminal emulator, such as HyperTerminal, use the following settings:

    Baud rate (or bits per second): 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: None
