Connector and Flat cable
The DE2011-DL scan engine is equipped with a Kyocera 21-pole ZIF con-
nector having a pitch of 0.3mm – series 6283 - ordering code 04 6283 021
00
2 868.
For further details and requirements related to the flat
cable, please refer to
the manufacturer’s datasheet, available at

Powerup sequence
In order to guarantee the correct operation of the engine, it is mandatory to
use the following powerup sequence timing constraints:
• VDD_SENSOR must be stable at 3.3V not late
r than 6ms after the VDD is
at 2.1V.
• VDD_ILLUM_SYS
must be stable at 3.3V at least 20ms before issuing
any camera start command.
Engine latency at powerup
At powerup the engine begins executing the code when the power supply
level reaches 2.1V. To complete the boot sequence, a 12ms time is required.
After this, the engine is ready to parse commands.
