DS6300 REFERENCE MANUAL2833.4 INPUTSThere are four optocoupled polarity insensitive inputs available on the scanner: Input 1(External Trigger/PS), Input 2 (Encoder), Input 3 and 4 generic inputs.The electrical features of the inputs are:Maximum voltage: 30 VdcMaximum current Input 1 and 2: 12 mA (scanner) + 12 mA (CBX)Maximum current Input 3 and 4: 12 mA (scanner)CBX100/500 Function+V Power Source - External TriggerI1A External Trigger A (polarity insensitive) for PSI1B External Trigger B (polarity insensitive) for PSI2A Input 2 A (polarity insensitive) for EncoderI2B Input 2 B (polarity insensitive) for EncoderI3A (CBX500 only) Input 3 A (polarity insensitive)I4A (CBX500 only) Input 4 A (polarity insensitive)I34B (CBX500 only) Common Reference for Inputs 3 and 4 (polarity insensitive)-V Power Reference - External TriggerThe active state of all the inputs is selected in software (open or closed). Refer to theGenius™ Help On Line.All inputs are optocoupled, polarity insensitive, and driven by a constant current generator;the command signal is filtered through an anti-disturbance circuit which generates adebouncing delay which can be set to 5 ms or 500 s. In particular, I1 for PS, I3 and I4 sharethe same value which usually corresponds to 5 ms when using a photoelectric sensor, whileI2 is set to 500 s when this input is used for the Encoder. The maximum Encoder frequencyis 2 kHz.Input 1 (External Trigger/PS) is used in the On-Line operating Mode and tells the scanner toscan for a code. The yellow Phase On LED (Figure C, 3) which refers to Input 1 is on onlywhen current flows through the input circuit and therefore when the active state of this inputis set to "active open", the LED lights up when the input corresponds to OFF.Input 2 is normally used for the Encoder input. The Encoder detects the conveyor speed.Inputs 3 and 4 can be used as the stop signal for the reading phase.The debouncing delay value can be changed through the software parameter Debouncing forInput x, see the "6-8 K Software Configuration Parameter Guide” or Help file.Powering InputsInput devices can be supplied by either scanner power (V+ and V-) or external powersupplies (Vext).Electrical isolation between the input command logic and the scanner is maintained whenpowering the input devices from an external supply voltage (Vext).
