The HHP IT3800 and/or 3900 are very common in self-checkout configurations for Evergreen ILS.
This document describes how to configure that device is a common setup. A modern Windows based PC, Keyboard Wedge, Quiet, Slow Scanner.
Use the Low Power scan rate, 67 samples per second
We set this to quiet and short
Configure a medium delay on good scans, long delay on duplicates.
Automatically scan the codes, no manual trigger needed; presentation leaves the lights off until a barcode is presented.
Try the wireless Honeywell 3800g.
Realistically, ANY scanner that acts like a keyboard, can scan your barcodes and can be programmed to do a carriage return after scanning the barcode will work just fine. Unlike some other ILS software, Evergreen is not picky.
