I/O vs. Shared Mem ory Mode

The Eth er net buffer RAM can be ac cessed in ei ther of 2 ways. In the typi cal NE2000 com pati ble

mode, the RAM is ac cessed through the NIC via I/O ports. An al ter nate ac cess scheme is avail able us -
ing the shared mem ory mode. In this mode it is soft ware com pati ble with the WD8013EBT from Stan -
dard Mi cro sys tems (for merly West ern Digi tal). In this mode a 32K win dow in the PC adapter space is
used to ac cess packet mem ory. The ad dress of this win dow is con trolled by the driver. For NE2000
com pati bil ity the I/O mode should be se lected. The jump er ing for each of the ac cess modes is shown
be low :

2.22.5

Me dia Type Se lec tion

The me dia type is also jumper se lecta ble via 2 pins on J35. The avail able choices are :

Twisted- pair 10BASE-T J22
Thin Eth er net Coax

1

AUI

2

J28

Twisted- pair 10BASE-T Re duced Squelch

3

The J35 jump er ing for each of the op tions is shown be low.

1

The thin Eth er net mode is not us able with the LBC- Plus. If thin Eth er net is re quired, it is nec es sary

to se lect the AUI mode and use an ex ter nal trans ceiver.

2

The AUI is con nected via J28. An adapter ca ble, WinSystems part number CBL- 147-1, is avail -

able which ter mi nates in a stan dard DB15 con nec tor.

3

The non- spec twisted- pair mode with re duced squelch lev els al lows the use of longer ca ble lengths

than speci fied in the twisted- pair speci fi ca tion, or the use of ca ble with higher losses.
