Electrical Integration
Integration Notes
Grounding
The mounting holes of the decoder are at ground. Mounting screws can be
used to implement connections to the host ground.
Based on the host characteristics, the additional ground connections can
affect:
•
•
It is suggested to investigate these topics at the beginning of the integra-
tion.
ESD
The decoder is protected from ESD up to ±2.0Kv@ connector.
During installation it is recommended to apply standard ESD handling pro-
cedures, such as operating in a properly grounded working area using wrist
straps.
EMC considerations
OEM decoder is designed to have a reduced radiated emission. However,
OEM decoder is a board to be integrated in a product and the compliance
must be done on the end product. It is suggested to investigate the electro-
magnetic compatibility topic when designing the host and the product inte-
grating OEM decoder. Please note that analysis of integration geometry,
shielding and grounding are crucial for EMI performance of the integrating
device.
Heat Dissipation
If the DB0431 is operated in a closed environment where the temperature
can rise significantly, particular care must be taken to properly dissipate the
heat generated by an intensive operative condition, like using ALWAYS ON
mode continuously for an extended time.
In some cases, the DB0431 might detect an overheat condition of the con-
nected scan engine and might apply power reduction strategies (like reduc-
ing FPS or turning off AIM laser).
The grounded screw holes are the main thermal dissipator for the OEM
decoder.
Electrical Interface
The DB0431 OEM decoder can be connected to an external digital platform
via a 27-poles ZIF connector supporting:
•
8
the decoder performance (if noise is injected into the decoder)
the radiated emission (depending on current loops)
In the specific case of DE2011 scan engine, when using "ALWAYS
ON" mode the AIM will be disabled by default.
