Is there a device that has multiple serial ports that I can connect to my computer so that I can connect other networking devices that can be configured from the serial port to this device and then configure these devices from my PC?

Here is a diagram of what I am trying to accomplish. I am looking for a device that I can use in the red position in the diagram.

  • What is the AUX port? Are you talking about a serial port? – heavyd Mar 7 '14 at 18:26
  • Yes, I'll edit my question – ρss Mar 7 '14 at 18:27
  • There is this that will do serial with an RJ45 (you'd have to get DB9 to RJ45 cables for it): digi.com/products/serialservers/connectportts4x4 - It might help to know more specifically what the devices/pinouts/uses would be. – MaQleod Mar 7 '14 at 18:27

You are looking for a serial terminal server or console server. Many manufacturers make them such as Raritan, Lantronix, and Black box.


As @Bert said, one way to do this is with a Serial Terminal Server or a Console Server.

However, if you will only be using one of these devices at a time and you will be in the same physical location, you could use a much simpler physical switch box, like this one:

4-port serial switch

These devices usually have a bunch of buttons or a dial on the front and they actually physically switch between the different connections and your computer.

It's much more old-school, but much easier and cheaper if that's all you need.

  • +1 Thanks this also a good idea, but it is not what I require. – ρss Mar 11 '14 at 8:09
