Chapter 2 Installation
Mounting orientation
When the E4000 is properly placed or installed, its front view looks like the picture below. In the middle is the lens,
the two sides are aimed, the upper is the decoding circuit board, and the screw mounting holes are below. At this time, the
relative orientation of the image captured by the E4000 correctly corresponds to its orientation.
Optical correlation
Window placement
The window is made of transparent media mounted on the front of the E4000engine to isolate the inside and
outside of the product and preserve the light path for the E4000 to read the bar code. The window should be placed so
that the illumination and aiming beams are emitted as much as possible and the reflections are prevented from entering
the engine. If the illumination beam is reflected into the engine, it will reduce the engine's read performance.
The window placement distance is obtained by measuring the distance between the E4000 front plane and the farthest
plane of the window. In order to ensure good reading performance, the vertical distance between the far end face of the
window and the front end face of the E4000 is no more than 3mm, and the vertical distance between the near end face of
the window and the front end face of the E4000 is not more than 2mm.
If the window needs to be tilted, the distance requirement is the same as the parallel installation. The tilt angle should
ensure that there are no various beams that can be reflected into the lens to ensure read performance.
