So remember that Shuttle computer we got a few weeks ago? Finally had time to install it as our backup shipping station and we couldn’t get the scale to work (its a serial port device). Turns out the motherboard “COM port dongles” were wired for a different kind of motherboard! So if you ever decide to do this yourself, note that the dongles come with ‘alternating’ pins when they really should not be. Check your motherboard documentation to verify which you need, and then a quick soldering fix!
