Hardware and Wiring
This section describes installation and wiring information for the interface ports. There
are two bi-directional serial ports, one parallel port with TTL inputs and outputs, and one
load cell input port. The serial ports are used to interface to 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. The load cell input is used
to interface to the scale platform.
Load Cell Connector - TB3
NOTE: JP1 and JP2 on the circuit board can be used to disable remote sensing.
