Introduction
The card also permits the host PC to act as a L

ORKS
network device, running
application-specific programs while the card handles lower layer functions such as
media access control, collision avoidance, and message validation
Firmware for the card is downloaded from the host PC. This allows the card to be
updated as new versions of the software and firmware are released, without modifying
or physically accessing the PCLTA-20 card. This feature extends the useful service life
of the card, and minimizes the cost and time associated with software and firmware
updates. The card is provided with 32Kbytes of off-chip RAM for use as network and
application buffers.
