CONNECTING TO A HOST TERMINAL
Six C48C units are used to monitor and control parts
packaging machines in a plant. C48C units are located at
each machine in the production area of the building. A
communication line is run to a PC located in the production
office. The drawing shows the line connection. Each
C48C is programmed for a different address and all are
programmed for the same baud rate and parity as the
computer (ex. 9600 baud, parity even). An application
program is written to send and receive data from the
units using the proper commands.
