Chapter 3 - Configuring a Touch System CARROLL TOUCH
3-2 Touch System Diagnostics (CTDIAG) User’s Guide
If autodetection does not successfully identify the touch system on your
computer, the Test Configuration Menu, shown in Figure 3-1, appears.
You will need to configure your touch system, which simply means
defining what combination of hardware and software is being used

Controller Type
CTDIAG supports the following types of touch controllers:
• Software-based controller (SBC).
• Hardware-based controller (HBC).
• Serial (RS-232) controller.
Note
The SBC requires the TAPI polling or TAPI interrupt interface
method; it does not function under the direct interface method.
Use the mnemonic or arrow key to select the type of controller to use;
note that it appears in the status line at the bottom of the screen. The
default controller is serial (RS-232).
If you need to change the communication parameters associated with the
SBC or HBC (interrupt number, I/O address) or serial controller (comm
port, baud rate, parity, stop bits), see Chapter 4, “Setting
Communication Parameters.”
