Cisco 675/678 Management Cable

The DataPro 6675 series cable is a replacement for the Cisco 675 or Cisco 678 Management Cable, commonly used to configure Cisco DSL modems. Remember those? They used to be so popular!

This cable is also referred to as a "Cisco Console Management Cable", and was the bane of existence for many a home-installer back in the late 90's and early 2000's.

This cable has an RJ45 Ethernet connector on the Cisco 675/678 router end, and a DB09F 9-pin serial connector on the PC COM port end.

This cable allows you to program and update your Cisco 675 or 678 router via Hyper Terminal or a similar application. Just plug the RJ45 end of the cable into the Cisco port marked "MGMT", and the 9-pin end into your PC RS232 port.

Custom lengths are available for this cable, if you need one.

If your PC has a 25-pin (DB25) COM port, you can use this cable together with our 9-pin to 25-pin serial adaptor, but it will not work on a 25-pin parallel port.
