Audio interface
Matrox 4Sight-II supports 16-bit stereo audio input and output along its audio
interface. The interface is only designed for line input/output operations. Because
there is no output amplifier or input preamplifier, it will not support speakers nor
microphones.
Parallel port
Matrox 4Sight-II has a parallel port to connect to a printer, or to other devices
that integrate a parallel interface. The port can operate in enhanced parallel port
(EPP) mode or extended capabilities port (ECP) mode. In addition to supporting
bi-directional transfer, these modes can transfer data up to ten times more quickly
than the "standard" parallel interface.
The parallel interface can be configured to operate in either EPP or ECP mode,
using the BIOS Setup program. For more information, please refer to BIOS
reference.
You can connect a standard floppy disk drive to the parallel port connector by
enabling the floppy disk controller. This is done by changing certain BIOS
settings. Refer to BIOS reference for information on the BIOS configurations
necessary to enable the floppy disk controller.
In addition, you will have to assemble a custom cable. Please refer to Connecting
a floppy disk drive to the parallel port connector for detailed instructions.
Auxiliary I/O interface
Matrox 4Sight-II can send and receive up to sixteen low-voltage TTL (LVTTL)
signals to and from external devices through the auxiliary I/O interface.
Auxiliary input signals have interrupt-generation capabilities. You can assign IRQ
10 to transmit the interrupt
appropriate menu item. For more information on the BIOS Setup program, please
refer to BIOS reference.
If you do not want the signals to generate interrupts, your application can poll the
auxiliary I/O bits to determine their state.
1. Note that the maximum interrupt frequency tested with the Matrox opto-coupling
module was 1 KHz.
