Product description
Bar code evaluation:
• All standard bar code types
• Max. 10 codes per reading pulse (max. 100 characters), max. 3 per scan
• Separation of identical bar codes of the same code type
• Code comparison (max. 2 matchcodes), can also be used as filter for the reading result
• Sort sequences: code position, FIFO, LIFO, code length list
• Manipulation of the data output string via filter or format mask
Reading pulse:
• External reading pulse, via switching input or serial interface
• Free running with timeout
• Continuous Read
• Reflector Polling for generating the reading gate automatically
Electrical interfaces:
• Serial host interface (RS 232, RS 422/485) with variable transfer rate, protocol and
telegram structure
• Serial terminal interface (RS 232) as auxiliary data interface with special diagnosis
functions
• CAN interface for integration in the SICK CAN scanner network or a CANopen network
• 2 switching inputs for external reading pulse and special function (e.g. teach-in of match
code)
• 2 switching outputs for signaling defined events in reading mode
Connections:
• All interfaces are connected via a cable with one 15-pin D Sub HD plug
• CDB 420 or CDM 420 Connection Module for connection to host (stand-alone) and for
integration in SICK CAN scanner network
• CMF 400 Connection Module Fieldbus in the CDM 420 Connection Module for
connection to field bus systems
