I bought one of these

eBay item #390167366953

Maybe I was naive but I expected this to contain a chip that did the
conversion. I plugged it in to a network and/or a Serial port but neither
was recognised. No driver disk was supplied, and I note that the DB9 has the
Cisco Systems Logo on it. The DB9 is moulded on so access without destroying
it is not possible.Any constructive suggestions as to getting it working
would be welcome.

Were you expecting to use this as a serial-to-Ethernet bridge? Because
that's not what it's used for. Some Cisco kit (and probably others as
well) uses an RJ45 socket to provide a local terminal connection.

Thanks for that. The illustration does not show the Cisco Systems logo on
the serial connector. The seller has a big pile of them to sell. I realised
I was taking a chance but maybe I can persuade PayPal to give me a refund.

To give the seller his due he refunded at once without asking for the cable
to be returned to him. Thanks Sam for the info.
