Step Three – Connect the USB-Serial AdapterĪfter I connected the Gearmo 4 port USB to Serial Adapter to one of the USB ports on the Pi I verified that it was recognized by the OS and that the devices were ready. Once the Pi OS has been upgraded we need to install the Serial 2 Network software. If this is a fresh install this could take some time to update all the packages. For the initial configuration I would recommend connecting the PI up to a display, keyboard, mouse, and the network. Once the new OS is installed and verified, insert the micro-SD back into the Pi. For the purposes of this tutorial I will be using Raspberry Pi OS 10-30-2021. Grab a micro-SD card for the Pi and flash the latest version of Raspberry Pi OS or whatever linux-based PI OS you would like to run and install the OS using balenaEtcher. I ran his article and figured I could test it out right away as I had a single USB-Serial adapter already and it would be easy enough to modify the configuration once the 4-port adapter showed up. ![]() I just needed to find a piece of software or way to configure the PI to work with the USB-Serial adapter.Īfter a quick search for Raspberry Pi Terminal Server I found Justin’s IT Blog and this article. I ordered it with free 1-day prime shipping. The Gearmo 4 Port USB to Serial RS232 Adapter.Īt the time (Jan 2022) it was ~$40. A quick search on Amazon and I found the second piece of the system. My idea then turned into a 24 hour mission to build a Pi-based terminal server with 4 RS232 ports. It has ethernet, 4 USB ports, and super easy to get up and running. I figured there had to be a way to build a terminal server out of a PI. I looked around my office and spotted a Raspberry PI 3B + that I had not been using. However, I didn’t feel like spending $200+ on something that I really will not use much after this project. There are also other brands out there like Digi, Lantronix, Cyclades, Xyplex, Avocent, etc… and they can sometimes be found for a reasonable price. The first thought that came to mind was the Cisco 2511 which had 16 async (serial) ports and an AUI ethernet port. My initial reaction was to hit up Amazon or Ebay to see if I could find a cheap and/or used network attached terminal server. I also needed to make the console for each of these devices available to remote administrators. While I could easily go into the basement and plugin a USB-Serial adapter into my Macbook and connect to each device individually, it wasn’t exactly convenient. I needed to be able to get to the console of two firewalls and a management server. However, I recently started building out a large lab environment in my home lab which was a mix of Meraki and Cisco Firewalls. Normally my lab environments are primarily made up of Meraki devices so there is no need for a terminal server. ![]()
