10 – APPENDIX A: Development Kit User Guide
10.1 – CR8000 Development Board
Development Kit Overview
The CR8000 development kit includes everything needed to integrate
the CR8000 (specifically the CR8011 or CR8012) Scan Engine into a
target design. We provide a complete Scan Engine, development breakout
board and all documentation required to quickly evaluate and integrate the
CR8000.
Scan Engine
The development kit comes with a complete CR8000 Decoded Scan Engine
with Bracket which includes the imager and decoder board integrated into a
single assembly. Please see Section 2.2 for details
on this assembly.
Development Board
The development board is the main user interface to the CR8000 kit. It
provides access to all features of the CR8000 Scan Engine including the
debug and development resources available.
Interface
J23 and J24 connect to the CR8000 decoder board. J23 connects
to the host interface connector and J24 connects to the expanded
illumination connector.
Trigger/Wake Up Switches
SW1 and SW2 allow the user to trigger a barcode read and wake the unit
up from Sleep Mode, respectively. If the unit is in a sleep state when the
trigger is pushed, the CR8000 will automatically wake up before performing
a barcode read.
Scan Interface
J1 interfaces to a RJ-50 connector that carries both USB and RS-232
signals to an external interface. The connector also provides a trigger signal
to activate the CR8000 remotely.
Indicators
The development board includes a speaker (SPK1) for audible indication as
well as a bi-color LED (D1) for visual indication.
Configuration Jumpers
A group of jumpers allow the development board to re-configure and access
different features of the CR8000. J7 and J8 configure auxiliary serial port
features that appear on J2 and J3. J5 configures serial port polarity, and J6
in conjunction with SW2 controls which boot mode the CR8000 enters upon
powering up. Finally, the CR8000 host port configuration can be changed
via the jumper block J9-J18.
Auxiliary Headers
J2 and J3 provide auxiliary and debug serial communications to the
CR8000, and J19 provides access to all of the expanded illumination I/O.
