Card Configuration

Each port of the PCL-740 card has two associated status jumper

groups and one six position DIP switch. If you do not use the boards

default settings then these all require configuring prior to use. I/O

port base address, interrupt level, RS-232/422/485/current-loop

driver mode and receiver status all require setting up. The functions

of the relevant DIP switches and jumpers are shown below.
