RS232 Command Sheet

Control your i3TOUCH remote via RS232 command protocol via serial cable connection or local network

All communication to the device should be sent with hexadecimal values.
Depending on the control software, verify that the commands are formatted and sent correctly as hexidecimal digits and not ASCII characters.

This document uses the prefix “0x” to indicate that the next characters are a hexadecimal base 16 digit. (i.e. 1 byte)
