CARROLL TOUCH Appendix A - Smart-Frame Protocol Command Reference
Touch System Programmer’s Guide A-17
05H* Communication error.
A communications error has been detected between the frame and 
controller (NOT between the controller and the host).
68705 Smart-Frame: Interprocessor comm error
8031 Pre-modular separate controller (UFP III): Comm error over the 
frame to controller interface.
8031 Smart-Frame (SDSF): All beams on at least one axis appear to be 
broken.
Modular: All beams on at least one axis appear to be broken - may be 
caused by having no frame attached to the controller.
06H 
& 
07H
Reserved.
08H* UART (Universal Asynchronous Receiver/Transmitter) error.
A parity or framing error was detected on data received from the host. 
Perform initialization procedures to reset the touch system.
09H* Serial overrun error on data received from the host.
Commands were received by the touch system faster than it could 
process them. Increase the timing delay between commands.
0AH* Invalid command received. A command that is not recognized as valid 
was received from the host. Note that a 0DH will be treated as valid 
command during the autobaud phase, but as an invalid command after 
the autobaud phase.
0BH External RAM (Random Access Memory) checksum verification error.
68705 Smart-Frame: N/A (No external RAM)
8031 Pre-modular separate controller (UFP III): Controller (External 
RAM)
8031 Smart-Frame (SDSF): Frame (ASIC RAM)
Modular: Frame (ASIC RAM)
0CH -
0DH
Reserved.
0EH* Power-On Reset (POR) Detected. 
The touch system has been reset (usually due to a power cycle) and the 
touch system has not yet been reinitialized.
0FH -
10H
Reserved.
11H* High Ambient Detected.
One or more beams are being treated as failed beams when determining 
the coordinates of touches due to excessive ambient light.
The beams are not failed, however, and when the excessive ambient 
light is removed, the beams recover immediately.
