Portland Temperature - Live

Well, here we go! A new project.

I decided to refurbish an old TemPageR unit, add some digital temperature sensors, and create a remote monitoring station. Something like this would be useful for a server room or a wiring closet, but it’s also a great addition to the lab. While this unit is a bit ancient, it still performs the task quite well and uses very few resources. It’s all powered by an embedded Lantronix XPORT server running at a terrifying 25 megahertz. The sensors themselves are digital.

When I first got the unit, it had no power supply and was in pretty rough shape. It had one digital external sensor and a built-in sensor on the board. I also did not have the password. Using some detective work, I figured out that I could get the password from the system if I used the Lantronix dev toolkit package to read the password directly from the config’s memory. It was in plain-text. Good for me, I guess.

From the Lantronix site:

AVTECH decided on the Lantronix XPort embedded networking module because of its ease-of-integration into their existing product design. XPort is an extremely compact, integrated Device Server that gives OEMs the ability to quickly and easily design Ethernet networking capabilities to virtually any device with a serial (UART) interface. Smaller than the average thumb, XPort includes all the essential features to network-enable OEM equipment, including a 10Base-T/100Base-TX Ethernet connection, proven operating system, an embedded web server, email alerts, a full TCP/IP protocol stack, and 256-bit AES encryption for secure communications.
