Chapter 1Introduction and Installation
About CM50
NLS-CM50 Area Imaging Engine, with small size and full automation design, is ideal as drop-in modules for OEM applications.
Combined with Newland`s decoding software, NLS-CM50 can easily read all kinds of 2D and 1D bar codes as well as OCR fonts.
This chapter will provide the installation instructions for the engine.
ESD Precautions
CM50 is shipped in ESD safe packaging. Use care when handling the engine outside its packing. Be sure grounding wrist straps and
properly grounded work areas are used.
Unpacking the Engine
After you open the shipping carton containing the engine, please check to make sure everything you ordered is present and also check
for damage during shipment. Report damage or short item immediately to your supplier. The shipping container is suggested to be
saved for later storage or shipping.
Dust and Dirt
CM50 must be sufficiently enclosed to prevent dust particles from gathering on the imager and lens. Dust and other external
contaminants will eventually degrade unit performance.
Mounting Orientation
There are two machine screw holes on the bottom of the engine. When the engine is in right direction (as shown below), these two
hole sites are downwards.

Interface Connector
Molex Connector 501912-2190 drawings taken from Molex Catalog page MX01. 0.3mm (0.012 in.) SMT, ZIF, Bottom Contact. Be
carefulwhen handling the connector and flex strip so as to avoid any damage to the connector. The connection between flex strip and
the connector should be solid and effective to ensure the engine`s normal work. Follow the connector manufacturer`s recommends to
select suitable flex strip including thickness, contact material and geometry.
