USB -> RJ45 console cable for CRS?

RouterOS Beginner Basics

Folks,
Where can one buy an RJ45 to USB console cable which would connect a modern laptop (which doesn’t have serial) to the RJ45 console port of the CRS125-24G-15-2HnD-IN desktop SOHO router?

Thanks!

While I continue my search, a coworker has lent me a spare Cisco DB9 → RJ45 console cable. I’m assuming these work with MikroTik hardware and am shopping online for a USB → RS232 cable which I can connect to the Cisco console cable.

Yes, this is the approach I use.

In case anyone else comes looking for answers on this, I’ve tested this setup with Fedora and it works OK. I didn’t see any setup docs on the wiki for Linux.

Configure serial connection for Linux

[] Use a Cisco-style RJ45-DB9 cable
[] Use a USB → RS232 cable (I used a TrendNet TU-S9)
[*] Assumes you have the ‘minicom’ program installed on a Linux OS (I used Fedora)

sudo /bin/minicom -s

[] Set device to ‘/dev/ttyUSB0’
[] Set hardware flow control to ‘off’
[] Set speed to 115200
[] Save config
[*] Re-enter minicom system and you should be good to go.

I use Putty on device /dev/ttyUSB0 on linux.
COM port on Windows.

In case you use Windows 7 and are to buy an USB adapter, make sure to NOT buy a Prolific chip based adapter.
See my post about Serial Connection With Windows 7.

Zap.

Just FYI, for 3 years I’ve never noticed problems described by you using Prolific PL-2303 XA/HXA converter on Windows 7.
