r/networking on Reddit: How do I build a USB to rollover RJ45 cisco console cable?
March 17, 2016 -
I haven't found a guide on the web and am wondering if anyone can point me to a how-to or show me the steps. Basically, I'd like to craft something like this: http://www.amazon.com/CableRack-Rollover-Console-Cable-Cisco/dp/B00GN5OHIW
I have a USB connector, cat5e cabling and RJ45 jacks. I assume there's some converting that has to be done in the middle to convert USB's 4 wires to cat5e's 8 wires.. I appreciate any help, thanks.

The link that you provided for the USB to console cable actually does more than a direct connection. It converts the USB to a serial connection then to the console pinout you will plug into your Cisco device. You won't be able to simply connect the wires from the USB to console cable.

I was in a pinch with a down cisco router and had to make one on the spot, basically it's 3 parts, 1: A usb to serial adapter 2: A serial cable 3: rj45 cable just cut the serial and RJ45 cables in half and join the wires according to This pinout guide Also note that a lot of usb to serial adapters automatically set the com port to something silly like com11 and many terminal apps like putty only work with com1 or com2, you often have to go into device manager and find the usb to serial adapter and manually set it to com1 or 2.

Mailing List Archive: Cisco USB to serial cable/pinouts
The documentation on cisco.com backs this... http://www.cisco.com/c/en/us/td/docs/routers/asr920/hardware/installation/guide/ASR920_HIG/hw_installation.html#pgfId-1281737 I find the decision to use a "Type A" USB port for this purely amazing, given that the USB spec explicitely forbids A-to-A cables, as that's just not how USB works (strictly host<->device and A<->B, always, if you have a host-to-host A-to-A cable it really has circuitry inside to make it look like a "device" to both hosts). Whoever designed this has been smoking interesting weed. OTOH, Fig. 3-23 suggests that there is a "real" USB host port (the "EIA Console Port") which might be able to drive a USB-to-serial, if it's the right now - if it can be used to connect a modem, it can be used to connect to a console server.
