Serial Scale Interface
Serial port 4 or the expansion port can be configured
for serial scale input. The serial scale function allows
other scale indicators to send gross, net, or tare weight
data to the
720i
. Once a serial port has been configured
to accept scale data, the data format can be customized
to match the data stream sent by that indicator.
To configure a serial scale, do the following:
1. Under the SERIAL menu, set the INPUT
parameter for the selected port to SCALE
(legal-for-trade serial scale) or IND SC
(industrial serial scale).
2. Return to the SCALES menu. Under CONFIG,
drop down and use the

to match the format sent by the serial scale.
The default serial scale format is:

decimal places should be specified as
