There are loads and loads of fake Prolific adapters. Does it work with their latest driver? Even if it does, it might be counterfeit. I know FTDI adapters are generally expensive, but I've had success with this cheaper one — it appears to be legit, or did when I last ordered some a while back. http://www.amazon.com/Chipset-Speed-Serial-RS-232-Converter/dp/B005S72HHO

Hi David. Thanks for the response. Yes I'm using the latest Prolific driver. The usb-serial adapter works fine @115200 talking to a ARM Cortex board. If I hook up a logic analyzer and setup the async serial profile I can see a transmission of 0x55, 0x18, 0x55, 0x18 (presumably from ProLink) but I see nothing being received. This is connecting the green (tx) wire on the USB adapter to pin 3 (rx) on the 29b and pin 2 (tx) on the 29b to the white (rx) wire on the USB adapter. Also, if I power up the 29b with the ground wire from the USB adapter connected to pin 7 (signal ground) I get a Frame Error 41 on the 29b display during self-test. No signal ground, it passes self test and drops into remote mode. This seems a bit suspect, I'll try a different 29b, I have a couple others. Suggestions welcomed.
