Questions & Answers
We would like to communicate with an Atex certified modem via TTL (TX/RX) communication. The Atex modem you have here has an USB connection. Is there a way to convert the USB connection to RX/TX communication? E.g. does the usb driver installed on the windows machine emulate a serial connection? Or would there be an Atex modem which would support TTL communication? (1 answer)
Hi Martijn! The FXA195 is designed to operate in a Microsoft Windows environment using an USB 1.1, 2.0 or 3.0 interface. There are some boards and adapters in the market that can convert USB to TTL, for example, the FTDI Chip company produces some of them. Unfortunately we couldn't test it, therefore we cannot confirm the compatibility.
