Vx cards installation and setup reference (PDF)

Hardware Requirements
One standard type II card slot, PC-Card compliant.
One available IRQ line (level sensitive).
16 bytes of available I/O space.
One Analog and Digital Cable (included in the standard package)

Hardware Installation
Installing the card : check for a free PC-Card extension slot and gently insert the card. Press down to set it firmly into the slot.
Interrupt request : the Interrupt Request (IRQ) number is set up at start-up by the PnP BIOS. Be sure there is at least one IRQ resource available.
I/O address : addresses are set up at start-up by the PnP BIOS.

Software Requirements
VX sound cards are managed by the VX kit, a comprehensive set of drivers for Windows and Mac operating systems. Latest VX kit version for your operating system.
In some particular cases, np runtime may be required by the OEM application used. Contact Digigram technical support for more information.
