Electrical Connections
Grounding
The chassis of the engine is at ground. Mounting screws can be used to
implement additional connections to the host ground.
Based on the host characteristics, the additional ground connections can
affect:
• the engine performance (if noise is injected into the scan engine)
• the radiated emission (depending on current loops)
It is suggested to investigate these topics at the beginning of the integra-
tion.
ESD
The engine 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.
Electrical Interface
The DE2011-DL scan engine can be connected to an external digital plat-
form via a 21-pole ZIF connector supporting:
• a parallel video port (8 bit per pix
el, vertical and horizontal synchs,
pixel clock)
• a signal to synchronize an external illumination system with the expo-
sure of the sensor (Flash
_out)
• three dedicated power supplies (for se
nsor, digital system, illumination
system)
•an I

C communication port for controlling the scan engine
Table 3 below describes the power lines and the
signals mapped on the 21-
pole ZIF connector.
