Live Weight Display
The Datalogic 1.12 OPOS Scale Service Object supports the ability to provide Live
Weight Display functionality in accordance with the UPOS Specification (version 1.9
and above). The user’s application may be written to take advantage of this capability in
the service (see the UPOS specification for details). In addition, the DualTest
application bundled with Datalogic’s services supports this capability and may be used
to demonstrate Live Weight Display function with a Datalogic scanner/scale. The
following screen shots represent the steps used to activate Live Weight Display with a
scale using DualTest.
To demonstrate Live Weight Display, start DualTest and follow the steps to Open and
Claim the scale, as described in the previous section. Then perform the following steps:
1. Set Status Notify True: Click the “Status Notify” check box.
IMPORTANT NOTE to OPOS Programmers:
PIDXScal_StatusNotify must be set TRUE while the scale is NOT Enabled. As
per the UPOS specification, setting
PIDXScal_StatusNotify TRUE after the
scale has been Enabled will not activate the Live Weight Display function in the scale
service object.
