Hi, I have an application to use the OX2 as a motor driver for a pan tilt unit for a camera assembly with absolute referencing( potentiometer feedback on each axis). Problem I have is that I have to write commands to the OX2 from a server that is approx 20 metres away and the USB won’t do the distance so have to RS232/485 direct onto the OX2. Can I do this and if so how?
You can communicate directly with the ATmega644 on the X2 via its hardware UART using TTL (5V), non-inverted serial. I recommend you use a wireless transceiver (such as an XBee) to transmit your data from your computer to the mega644’s UART.
