Appendix B - Smart-Frame Protocol II Function Reference CARROLL TOUCH

B-28 Touch System Programmer’s Guide

The touch system responds with the following report:

E0 03 02 20 00 FF

This report indicates that the second parameter byte was erroneous via

Cmderr (the 02 byte), and echoes back the parameters that the host

sent. The fact that Cmderr is set to 02 reflects the fact that the touch

system expected more parameters than were actually received.

If the host sends the SetTouchModes (20H) command as follows:

66 04 20 01 01 01 FF

The touch system responds with the following report:

E0 05 00 20 01 01 01 FF

This report indicates no errors in Cmderr and reports the values for the

three parameters defined for the function after the parameter values

were changed as a result of the host sending the command (the three 01

values in the report).
