I can use an Arduino Uno and the libraries to communicate with the Reader. But when I try to connect a FTDI cable to the board, without the arduino attached, I am not able to communicate with the board using the Universal Reader Assistant software. The FTDI cable is functional, I can loop TX to RX and see the characters come back. When I look at the RX and TX lines using a scope, as soon as a character is sent all I get is very high frequency noise on the serial port lines. I’ve tried several FTDI Cable, other serial to TTL cables, and a USB isolator on the FTDI Cable. Has anyone else seen this issue? Has anyone been able to use the reader with an FTDI Cable?
