Hall Effect Switch:
The scanner module also adds a Hall Effect Switch (HE Switch) that enables the unit to
automatically set the Trigger mode of the Scan Engine depending on the location of
anexternal magnet (included in scanner cradle).
The output of the HE Switch switches low (turns ON) when a magnetic field (south
polarity) perpendicular to the Hall sensor exceeds the operate point threshold, BOP
(typically 100 G magnetic field). When the magnetic field is reduced below the release
point, BRP, (typically 45 G magnetic field) the HE Switch output goes high (turns OFF).
The Hall Effect Switch goes to the USB Controller's DSR input. As the HE Switchopens
or closes, it causes the USB Controller to initiate a USB Interrupt message to thehost.
When the Host Application software detects the DSR input active LOW via theUSB
Interrupt and a CDC message (HE Switch is ON), it sends a 'Continuous Trigger'SSI
command.
