Hardware and Wiring
This section describes installation and wiring information for the interface ports. There
are three bi-directional serial ports and one parallel port with TTL inputs and outputs.
The serial ports are used to interface to a weight indicator, a printer and to a host device
or PC for continuous output. The parallel port is used to interface to parallel printers and
for remote switch input and relay control using the TTL I/O.
