Resolution / Answer


By default, the DS3608-ER is configured for 'Extended Range Full Power Mode'. If connected to a host terminal such as the ET50 or ET55 tablet which does not provide enough current (only 500mA), Parameter # 1777 - DS3608-ER Power Mode can be changed to 'Extended Range 500mA Compatibility Mode'.

This parameter is first introduce in firmware version CAACJS00-004-R03.


Scan the following barcode 'Extended Range 500mA Compatibility Mode' or the one from e-page 146, section 5-20 of the DS36x8 Product Reference Guide. Download Files>>

DS3608-ER Power Mode
Parameter # 1777 (SSI # F8 06 F1)

This parameter determines whether the DS3608 extended range digital scanner enters full power mode or 500mA compatibility mode. When selecting the 500mA compatibility mode parameter, you may experience decreased decode performance when scanning in low light or dark environments at an extended range.

To switch back to 'Extended Range Full Power Mode', scan the following barcode.
