Firmware Update with DualTest
The Datalogic 1.12 OPOS Scanner Service Object supports the ability to update
firmware on select scanners 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 upgrade firmware on select scanners. The following screen shots represent the steps
used to upgrade firmware on a scanner that supports this ability using DualTest.
CAUTION
To perform the firmware update, start DualTest and follow the steps in the previous
section to Open and Claim the scanner. Then perform the following steps.
1. OpenFile: Locate the firmware file on your machine or network.
IMPORTANT NOTE to OPOS programmers:
Prior to performing a firmware update on a scanner, the Scale Service Object
should be closed. Failure to follow this step could lead to firmware update
failure and an inoperative scanner.
Firmware files are interface and scanner specific and may be obtained from
Datalogic Tech Support.
