MATRIX 300™ REFERENCE MANUAL6044.5 INPUTSThere are two optocoupled polarity insensitive inputs available on the reader: Input 1(External Trigger) and Input 2, a generic input:The External Trigger can be used in One Shot Mode or in Phase Mode. Its main functionsare: acquisition trigger in One Shot Mode reading phase-ON/reading phase-OFF command in Phase ModeThe main functions of the general purpose Input 2 are: second external trigger in Phase Mode match code storage command when the Match Code option is enabledThe electrical features of both inputs are:VAB = 30 Vdc max.IIN = 10 mA (reader) + 12 mA (CBX) max.The active state of these inputs are selected in software. Refer to the VisiSet™ Help OnLine.An anti-disturbance filter is implemented in software on both inputs so that the defaultminimum pulse duration is 0.5 milliseconds. This value can be increased or decreasedthrough the software parameter Debounce Filter, see the Digital I/O folder in the VisiSet™Help On Line for further details.These inputs are optocoupled and can be driven by both NPN and PNP type commands.NOTE: Polarity insensitive inputs assure full functionality even if pins A andB are exchanged.The connections are indicated in the following diagrams:CBX100/500 Function+V Power Source - External TriggerI1A External Trigger A (polarity insensitive)I1B External Trigger B (polarity insensitive)-V Power Reference - External TriggerThe yellow Trigger LED (Figure 13, 5) is on when the active state of the External Triggercorresponds to ON.
