Message: Driver is not installed
Meaning: The appropriate TAPI driver for the controller must be 
installed in order to execute.
Action: Install the appropriate TAPI driver (HBC, SBC, 
RS-232).
Message: Frame fail to respond
Meaning: CTDIAG cannot communicate with the HBC or RS-232 
controller or Smart-Frame.
Action: • Check that power is supplied to the RS-232 
controller or Smart-Frame.
• Check that the communication cable is properly 
connected to the correct comm port.
• Check that the controller or Smart-Frame jumpers (if 
any) are set to either autobaud or to a fixed baud rate 
and parity that matches those shown on the Status 
line.
• Check the Status line to see that the stop bit is set to 
1.
• Check the Status line to see if the COM parameter is 
set to the comm port to which the touch system is 
connected.
Message: Hardware missing, poor connection, 
incorrect address or interrupt
Meaning: CTDIAG cannot communicate with the SBC in the 
Touch Coordinates screen. 
Action: • Check that the controller card is installed properly in 
the PC.
• Check that the frame is connected to the controller.
• Check to ensure that the I/O address and interrupt 
number settings on the controller match those on the 
Status line.
• Select another I/O address and interrupt number 
setting to avoid possible conflict with other 
hardware in the PC. The addresses of other hardware 
may be found in the IBM AT I/O Port Map of your 
controller installation instructions.
