Data format refers to the type of packet the controller uses to send the X/Y touch coordinates to the host system. Format Tablet is the default format for the 3M™ MicroTouch™ EX712 controller. In Format Tablet, the controller sends 5 bytes per point and provides the most rapid response time to a touch. - Page 17 The general format of a command is as follows: <Header>Command<Terminator> Note: The following descriptions of header, command, and terminator, use 3M Touch Systems terminal emulator key sequences. You may need to enter the sequence in a different format, depending on your emulator.
