MVP 2023 Joe Tauser Posted July 20, 2018 MVP 2023 Report Share Posted July 20, 2018 1. Download the U90 software from this site. 2. If you don't have a communication cable, find your local Unitronics distributor and get an MJ10-22-CS25. Or order it online. 3. If your computer doesn't have a serial port, you'll need a USB to serial converter. Find one with the Prolific PL2303 chipset or get a Unitronics MJ10-22-CS35. Joe T.
