Ethernet
The VXIpc-850 uses the SMC 91C92 ISA-Ethernet controller from
Standard Microsystems Corporation as a 10BaseT node. The
VXIpc-850 provides four diagnostic LEDs that are activated by
transmit-and- receive activity, by link integrity status, and when the
91C92 register space is accessed.
The 91C92 supports IEEE 802.3 and you can reconfigure it without
changing jumpers. In addition, it does not require any memory space,
using 16 bytes of I/O space for all communication.
Configuring Your Ethernet Addresses
National Instruments programs the E thernet address and other values
into a serial EEPROM from which the 91C92 loads its power-on
configuration . The defaults should be adequate for most situations;
however, using the ISMC9000 software, you can change the default
settings (except the E thernet address) for the needs of your system.

The ISMC9000 software resides in
c:\images\enet
. Under
DOS or a DOS shell under Windows, type
c:\images\enet\ismc9000
to run the configuration
program. If you do not want to change the default settings, you do
not need to run this program.
