Product Review (submitted on September 6, 2021):

This was my third attempt to find a serial converter for a project at work. The first worked fine for everything I connected it to - except the device I needed to connect, the second used counterfeit chips (Returned for full refund), and this was the third.Short version - If the Rx to the computer works, but the Tx from the computer doesn't, you may need to get a 5V adapter (like this one). The RS-235 spec says up to 25V, so 5V is safe for anything. (3.3V is sometimes to low to be considered "high")
