TableScanner = USBScanner
Settings are identical to USBHHScanner/HandScanner, except that Usage =
18944
(4A00 hex), and DeviceNameOverride = “…USB Scanner”
Scale
Under the SCALE in the registry, there are five named entities. Some are redundant and
have been maintained for legacy applications. The following screen shots cover the
important user-configurable settings for each category of scale.
MagellanSC = SCRS232Scale
IMPORTANT NOTE: COM port settings for this scale device are identical to
the corresponding scanner names; this is because the two devices share
the same COM port and must use the same communication parameters.
The same caveats apply to changing these values in the registry and scan-
ner/scale – the settings must match.
