Communication, Touch Screen and Power Connection Overview Diagram
The Devil Ray controller will automatically detect and configure itself for the communication and touch screen type
connected. The controller can differentiate between the industry’s two most common 4 and 5 wire touch screen pinouts as well as detect an 8-wire touch screen connection. In addition, it will automatically detect a USB or a serial
(RS-232) connection. This eliminates the need to configure the Devil Ray controller manually for any analog resistive
touch screen type or RS-232 or USB communications. Refer to Fig. 6.0 for the correct connection procedures.
