[Sub16]

Hi guys

I got a Unitek Y-7503 2 Port Serial PCI card.
I install the Windows XP Pro 32 Bit driver and it installed fine.
But when i went to do the slicer driver it gave me an error.
Does anyone know how i can get this going.
Or could anyone tell me which PCI serial like Make a model to get
please thank you

The slicer driver is needed for a 2 or 4 level interface. For these interfaces, PDW needs direct hardware access to the serial port, which is established through the slicer driver. If you use a PCI or PCMCIA card, PDW can't get access to its hardware due to the PCI or PCMCIA driver.
 
From http://www.discriminator.nl/4-level/index-en.html - 'The interface is connected your scanner's or receiver's discriminator output and to your PC's serial port. That should be a 'real' serial port on your PC's motherboard. An RS232 to USB converter or a PCMCIA/PCI card with one or more serial ports will not work.'

If you use an RS232 interface, you don't need to install the slicer driver, as this interface observes the standard RS232 protocol.
