104-ETH to implement Plug and Play & NE2000 compatibility . The Radio and Ethernet adapt-
er can be configured for Full Duplex.
However, this is not recommended
for the PCFW-104-
ETH. The full duplex function enables simultaneous transmission and reception on the twisted
pair link to a full duplex Ethernet switching hub. This mode of operation is only recommended
for the FGR-115RE when connected to a LAN Switch.
PnP and Jumperless modes
The Microsoft Plug and Play function frees the user from setting the PCFW-104-ETH configu-
rations such as I/O and memory address and IRQ, etc. For certain applications Plug and Play
cannot be used. For cases such as these the RTL8019AS also supports jumperless operation.
In jumperless mode the configuration parameters can be configured using the RSET8019.EXE
utility provided on the utilities disk.
LAN Parameters
The LAN adapter should be configured for Half Duplex and Autodetect mode. Configuration
for Full Duplex is recommended only for switches and the PCFW-104-ETH cannot function as
a switch.
I/O addressing
The PCFW-104-ETH supports 16 base I/O addresses. The I/O address will be automatically
configured in a Plug and Play environment. In a jumperless system the module can be config-
ured to any of the available address ranges shown below in Hex.
0x200 - 0x21F
0x220 - 0x23F
0x240 - 0x25F
0x260 - 0x27F
0x280 - 0x29F
0x2A0 - 0x2BF
0x2C0 - 0x2DF
0x2E0 - 0x2FF
0x300 - 0x31F
0x320 - 0x33F
0x340 - 0x35F (Factory Default)
0x360 - 0x37F
0x380 - 0x39F
0x3A0 - 0x3BF
0x3C0 - 0x3DF
0x3E0 - 0x3FF
The PCFW-104-ETH is supplied pre-configured in jumperless mode with a default I/O address
of 0x340h.
Interrupts
The PCFW-104-ETH can be software configured to generate interrupts on one of eight PC/104
