PORT 2
PORT 4 CMD
SCALE
IND SC Specifies the type of data received by the port:
SCALE: Legal-for-trade serial scale input
IND SC: Industrial (non-legal-for-trade) scale input
KEYBD is available only on Port 1; SCALE, IND SC are available only on Port 4 and higher
(expansion ports).
Note
The keyboard interface is not hot-pluggable. Power-off the 720i
before attaching keyboard cable to the Port 1 connector.
DO NOT EDIT PORT 3 PARAMETERS. Port 3 provides communications
with the detached display module (DDM); changing these parameters will disable the
display.
Print format outputs default to Port 4; if using Port 4 for other scale connections,
reassign needed print formats to another port before configuring.
