6.1.7 NCI POS
6.1.7.1 OVERVIEW
The serial communications protocol is used to interface Weigh-Tronix/NCI POS (Point-of-Sale) scales to
ECR (Electronic Cash Registers), or other computing equipment (eg. personal computers).
Baud rate and parity will be configurable. Start and stop bits will each be fixed at one (1). Data bits will be
fixed at seven. Baud rates supported will be 1200, 2400, 4800, 9600 and 19200.Responses to serial
commands will be immediate, or within one weight meter cycle of the scale. One second should be more
than adequate for use as a time-out value by the remote (controlling) device.
There are two types of serial commands:
mandatory
and
optional
. Mandatory commands must be
supported by all products.
If weight is negative, in motion, over capacity or under capacity, or if a zero error exists, only the scale's
status is returned in response to a weight ('
W
') command.
