Connecting a C-more touchscreen to the cRIO
 

Does anyone have any clue as to how our team could hook up one of these to the cRIO as a joystick? THey have an RS232 output that supports the modbus protocol. My team is currently considering using some sort of arduino-like thing to connect it or simply hooking it up to the digital input and output on the PSoC.

Any ideas? :)
