COMMAND/RESPONSE DESCRIPTION
Automatic Baud Rate Selection (0D)
For most applications a jumper selected baud rate is recommended. If automatic baud rate selection is required, contact the
factory for assistance. (The autobaud command will be ignored if a specific baud rate is jumper selected.)
DC1, Ctl Q, XON Software Handshaking (11)
DC3, Ctl S, XOFF Software Handshaking (13)
RS-232 flow control is provided by these commands. Note: A shunt must be placed on Jumper A (SOFTHAND) to allow
software handshaking. Absence of a shunt requires hardware handshaking. (See also ENABLE TOUCH PANEL command.)
*Enable Touch Panel (26)
Disable Touch Panel (stop scanning) (27)
The touch panel must be enabled for normal operation. When the touch panel is disabled, commands are processed as
they are received, allowing changes in modes of operation, but discarding any report operations.
This differs from XON/XOFF software handshaking. When the touch panel receives an XOFF character (13), commands are
executed until the touch panel requires transmission of a report, then all commands received are buffered and are not
executed until an XON character is received. If the buffer becomes full, the touch panel sends XOFF.
Enable CONTINUOUS/disable TRACKING mode (24)
*Disable CONTINUOUS/disable TRACKING mode (25)
This coordinate reporting mode will continuously report the coordinates of a stylus that remains in the touch panel. This
mode can be used individually or in combination with ENTER point, or EXIT modes. The following report format is used. If
more than one stylus enters the touch panel, a non-contiguous report will be generated.
41 = start of coordinate report
xx yy = binary X and Y, > = 0, X, Y = FE if non-contiguous
