Cheers for the replies guys - I'm really interested in the rational behind moving to USB from traditional RJ45 ports....realestate?....boggles the mind.

Hi, there is both a USB signalled console port, and an RS232 console.
The RS232 console uses a USB style connector, which is very, very poor.

Is that the "EIA console" port?  On an USB A-type connector?


Check out "Figure 1-2 Front Panel of Cisco ASR-920-12CZ-D Router" on this page:

"Console port (TIA/EIA-232F)" is RS232 on a USB connector.
"Auxiliary Console port" is also RS232 on a USB connector.

The only USB signalled ports are down the other end of the router.

Cisco sell a cable that gives you an RJ45 RS232, it???s just wires, no active components in there.

USB RS232 cable, but what you write scares me deeply...

Yeah, it's naff. Really, really, naff.
