E271-2200 and E271-2210 Controllers 111
In mode 00, the controller transmits a single coordinate only upon first
touch in ASCII hex format. Seven ASCII characters are transmitted as
follows:
XX<,>YY<CR><LF>
The "XX" and "YY" values are each two characters, made up of uppercase
hex values from 00 to FF. <CR> and <LF> are carriage return and line feed
characters.
Mode 01 - ASCII/Single-Point/Untouch Flag N/A; 1,3
In mode 01, the controller transmits a single coordinate upon first touch
and another coordinate for the untouch location, possibly different. Nine
ASCII characters are transmitted in the format:
XX<,>YY<,><T|U><CR><LF>
As in mode 00, the "XX" and "YY" values are each two characters, made
up of hex values from 00 to FF. Mode 01 differs from mode 00 in that a
"U" or "T" character indicates if the coordinate is for first touch or
untouch. For example:
7F,34,T<CR><LF>...............7F,34,U<CR><LF>
Mode 20 - ASCII/Stream/No Untouch Flag J2-Y, J4-N, J10-Y, J11-Y; 0,3
Mode 20 differs from mode 00 in that coordinates are continually updated
and transmitted until untouch. Untouch status is not reported. For example:
7F,34<CR><LF>72,32<CR><LF>6F,31<CR><LF>6E,34<CR><LF>
Mode 21 - ASCII/Stream/Untouch Flag N/A; 1,3
Mode 21 is like mode 20, with the addition of the touch/untouch flag. For
example:
7F,34,T<CR><LF>72,30,T<CR><LF>72,32,T<CR><LF>72,32,U<CR><LF>
Mode 06 - Binary/Single-Point/No Untouch Flag N/A; 0,2
Mode 06 is the first mode discussed that transmits optimized binary data.
In this mode, touch coordinates are transmitted with only three characters.
The application can read these values directly into numeric variables
without conversion.
