Input Line Details

The general purpose input line signals are connected to I/O lines 1 and 2, which have the following
features for control or status indication.
Feature set: LineSelector (RW), LineName (RO), linePinAssociation (RO), LineFormat (RO),
•
LineMode (RO), lineDetectionLevel (RW), lineDebouncingPeriod (RW), LineInverter (RW),
LineStatus (RO).
Connector: See 10-pin I/O Connector Details for connector pinout and electrical information.
•
The cable shell and shield should electrically connect the Genie Nano chassis to computer
chassis for maximum EMI protection.
Line Transition Validation: Each input incorporates a signal debounce circuit (following the
•
opto-couple) to eliminate short noise transitions that could be wrongly interpreted as a valid
pulse. The duration is user-programmable from 0µs to 255µs with CamExpert.
Line Signal Propagation & Timing: Maximum delay values are defined in Input Signals
