CARROLL TOUCH Chapter 4 - Setting Communication Parameters
Touch System Diagnostics (CTDIAG) User’s Guide 4-5
Type the value for the I/O address; if the value you typed is outside the
allowable range of 200H to 3F0H, an error message appears and the I/O
Address Menu reappears.
The I/O address at which the HBC attempts to communicate with the
touch system may be set by configuring jumper switch blocks on the
controller. See the HBC controller installation instructions for details.
The controller I/O address must match the CTDIAG I/O address.
If you configure the HBC to use an I/O address of 300H (the default
setting), there is no need to change this parameter in CTDIAG because
the CTDIAG default is also 300H. If the HBC is configured to use an
I/O address other than the default, CTDIAG and the controller must be
set to the same I/O address.
HBC Interrupt
The hardware interrupt request line is a dedicated hardware line
between the touch system and the computer. It defines where to search
for an HBC.
The interrupt number at which the HBC attempts to communicate with
CTDIAG may be set by configuring jumper switch blocks on the
controller. See the HBC controller installation instructions for details.
The controller interrupt must match the CTDIAG interrupt.
If you configure the HBC to use an interrupt number of 7 (the default
setting), there is no need to change this parameter in CTDIAG because
the CTDIAG default is also 7. If the HBC is configured to use an
interrupt number other than the default, CTDIAG and the controller
must be set to the same interrupt number.
TAPI Communication Parameters
The TAPI Communication Parameters Menu (Figure 4-5) lets you
define the software interrupt for the TAPI driver. Type the hexadecimal
value of the new address, then press ENTER.
