Parallel Protocol
Overview
This chapter describes hardware and software protocol information
necessary for parallel communication between the 150XB/C and host
computer without using an SP232 module. All commands and
instructions remain the same as when using an SP232 module.
Note: In order to use the 150XB/C in parallel communication mode,
you must have a parallel interface cable that attaches between the
150XB/C Option Port connector and the host computer.
This cable is not furnished. You have to supply your own. Please
refer to the next page for a list of pinouts necessary to manufacture
the interface cable.
Also, the host computer must have a parallel I/O card (Anasco
41-404 for example) installed before parallel communication is
possible.
Setup - Parallel Interface Cable Setup
1. With the 150XB/C turned off, plug the parallel interface cable
into the connector at the back of the Option Port. There is no
module installed in the Option Port.
