I'm trying to use a USB-to-Serial converter on a Brightsign LS322 unit, but I can't get it to work properly.
I'm using the USB-Serial converter that HMS Electronic sells with its boards, so it has the Prolific chip that is required by Brightsign. I want to use one of HMS' serial input boards to connect more than 8 buttons to the unit.
1. Can you use a USB-to-Serial converter on the LS322's USB port?
2. If yes - how do I interface with the board in Brightauthor? I have tried the "USB input" option in Brightauthor, but it seems the Brightsign doesn't read the inputs from the board. I've already tried different I/O-port settings, but still can't get it to work.
Any idea would be much appreciated.
