DS5100 REFERENCE MANUAL6644.5 INPUTSThere are two optocoupled polarity insensitive inputs available on the scanner: Input 1(External Trigger) and Input 2, a generic input:The electrical features of both inputs are:Maximum voltage: 30 VdcMaximum current: 12 mA (scanner) + 12 mA (CBX)An anti-disturbance filter is implemented in software on both inputs so that the minimumpulse duration is 5 milliseconds. This value can be increased through the softwareparameter Debounce Filter, see the "5K Family Software Configuration Parameter Guide”Help file".CBX100/500 Function+V Power Source - External TriggerI1A External Trigger A (polarity insensitive)I1B External Trigger B (polarity insensitive)-V Power Reference - External TriggerThe External Trigger input is used in the On-Line operating Mode and tells the scanner toscan for a code. The active state of this input is selected in software. Refer to the GeniusHelp On Line.The yellow Trigger LED (Figure A, B, C, D, E, 7) is on when the active state of the ExternalTrigger corresponds to ON.This input is optocoupled and can be driven by both an NPN and PNP type command. Theconnections are indicated in the following diagrams:EXTERNAL TRIGGER INPUT CONNECTIONS USING SCANNER POWER(brown)(black) (blue)PH-1 Photocell (PNP)Figure 43 – PH-1 Photocell (PNP) External Trigger Using Scanner Power
