6. Carefully insert the card into the vacant slot, and push until it is firmly seated. Screw the

metal bracket at the end of the card to the computer case (this must be done to minimise

ground-conducted interference).

7. Replace the computer case and reconnect the power cord.

8. Plug a speaker or headphones into the audio jack at the rear of the card. Alternatively, if

you have a sound card and wish to route WiNRADiO through it, you can plug an audio

‘patch’ cable from the audio jack to the ‘Line In’ jack on your sound card. Note that a

3.5mm stereo plug must be used, otherwise you will hear no audio from the receiver. A

suitable patch cable is included with the WiNRADiO Digital Suite option.

9. Connect the antenna to the BNC jack at the rear of the card and extend the antenna up

and as far away from the computer as possible.

10. If you have a plug-and-play computer, you may have to configure the BIOS under

'PNP/PCI CONFIGURATION' to set the appropriate IRQ and DMA to 'Legacy ISA'

instead of 'PCI/ISA PnP' to avoid conflicts with any plug-and-play devices in your

computer. You should also make sure that any PCI IRQs are not the same as

WiNRADiO's.

Jumper Settings

The WiNRADiO receiver card is provided with jumpers which select the desired I/O port

address. The jumper may need to be changed from the factory default settings to avoid

conflicts with other cards already installed in the computer.

There are eight possible I/O addresses which the WiNRADiO card can use: 180, 188, 190,

198, 1A0, 1A8, 1B0 and 1B8 (all specified in hexadecimal). There are also 8 different IRQs:

3, 5, 7, 9, 10, 11, 12 and 15, and 2 DMA channels: 0 and 3. The factory default is I/O port

180, IRQ 12 and DMA 0.

If more than one WiNRADiO card is to be installed in the computer (up to 8 depending on

available address lines), each card must be assigned a unique I/O address and IRQ. The

DMA channels can be shared, all eight are able to run on one DMA channel, but it is

recommended to evenly distribute the card’s DMA settings across the two channels if

possible.

Some of the WiNRADiO IRQs can be used by other devices, for example: IRQ 3 is normally

used for COM2, 5 for a sound card, 7 for an EPP or ECP printer port, 9 for a video card, 10

for a network card, 11 for a SCSI card, 12 for a PS/2 mouse port and 15 for the secondary

IDE port. If you wish to use any of these interrupts, make sure that either these devices don’t

exist, or disable them.
