I connected the PL2303HX into the USB port on the computer, the plugged in the serial end to the Psion connecting cable and then into the Psion port, the \pc shows it trying to connect but it fails.
Thank you for contacting Plugable support! I’d be more than happy to assist you with this issue.
You may need to change the serial port settings such as baud rate, com port, etc to successfully communicate with your device. These settings should be available from your device manufacture.
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
