Serial/SMT Controllers
The Serial/SMT controllers are compact (3.5 x 2.25 x 0.3 inches),
RS-232 serial controllers. The controller can be internally mounted in
your monitor, or enclosed in a molded plastic case (3.75 x 2.5 x 0.9
inches) and mounted to the back or side of your monitor.
Daughterboard Controllers
The Daughterboard controller is a CMOS serial add-on board (3.5 x
2.25 x 0.3 inches) that you mount onto your CPU board. You can
easily integrate the Daughterboard controller onto a system board you
may be designing.
PC Bus Controllers
The PC Bus controller is a half-slot, bus card that you install in your
system. It has its own serial communication (COM) port, enabling you
to use your existing COM ports for other peripherals.
To use the PC Bus controller, your computer must have an available
16-bit ISA (Industry Standard Architecture) expansion slot. The
touchscreen cable connects to the port on the controller.
TouchPen Controllers
The TouchPen controller offers the same features as the Serial/SMT
capacitive controller, with the addition of pen support. The controller
can accept touch input from both a finger and the touch pen.
This RS-232 serial controller, which measures a trim 1.35 x 4.8 x 0.3
inches, is designed to easily fit inside flat panel displays and CRTs.
The TouchPen controller is always mounted internally.
The tethered touch pen attaches to your display. Several cable lengths
are available.
