3.0 INSTALLATION
This section describes how to configure the port address and base
memory address and how to install themodulein thepersonal
computer.
3.1 Initial Installation
ThePC Link Interfacemodulecan beinstalled in any ATĆcompatible
personal computer. The module requires an I/O port block of 8 bytes
and 16K of host memory space. The port address is set using the DIP
switches on the module. The memory address is set under software
control by writing to a specific port in the port block.
3.1.1 Configuring the Port Address
Beforeinstalling thePC Link Interfacemodulein thepersonal
computer, you must select an I/O port address for the module. The
switches on themoduleset thebaseport address of the8 byteI/O
block used to load software and access the module. Table 3.1 shows
thepossibleport locations and thecorresponding switch settings. It
is suggested that unless there is a conflict with some other hardware
in your personal computer you do not change the port location from
its default value(0x0250). If multiplemodules areinstalled in the
same personal computer, each must be assigned a separate port
address. Notethat if you areusing thePC Link Interfacemodulewith
the AutoMax Programming Executive software, the port location must
beset to oneof thefollowing: 0x0250, 0x0258, 0x0260, 0x0268. No
other port locations are recognized by the Programming Executive
software.
