CHAPTER 2 Optimization and Trigger
Programming
Introduction
The HE45T comes with SXGA mode and its dual field optical system activated
for all the triggers. From the moment you turn on your HE45T, you are taking full
advantage of the dual path 1.3 megapixel imager and the
400 MHz processor with Microscan’ industry leading DPM technology.
The HE45T is easily customizable; each trigger can be independently
programmed for different behavior.
• Near Field (NF) — The nearest field of the HE45T’s two image fields. It has
an optimal focal point of 4” (101.6 mm) away from the lens of the reader.
The width of the Field of View is 1.5” (38.1 mm) at the optimal focus point.
• Far Field (FF) — The farthest field of the HE45T’s two image fields. It has
an optimal focal point of 9” (228.6 mm) away from the lens of the reader.
The width of the Field of View is 4” (101.6 mm) at the optimal focus point.
The following sections provide you with the ability to program individual
triggers, or all triggers, to perform with different parameters.
