2.2 Electrical Description
The PC Link Interface module contains a V40t microprocessor with
128K of RAM to implement the lowĆlevel communications functions.
The module's memory is divided into 8 blocks of 16K bytes. The
module's memory map is mapped into a 16K window of host
memory space. The module's memory block contains all the tables
and buffers that are used to pass information to and from the
network. There is no ROM on the module. The appropriate interface
software is downloaded to the module, enabling Remote I/O or
Network Communications using the same module by loading the
appropriate software onto the PC Link module.
