I/O Type: Single Ended 5v Inputs / Outputs
Circuit Type: Sink (4.7K ohm pull-up to internal +5v)
Input Impedance: 4.7K ohms to internal +5v
Maximum Input Voltage: -1.0 v , +7.0v
Logic 0 Input Threshold: +0.8 v max
Logic 1 Input Threshold : +2.4 v min
Input Filtering: 10 microseconds typical
Output Sink Current 10 ma max
On State Output Voltage +0.5v at 10 ma
Strobe Response: Minimum Pulse Width: 10 microseconds.
Position Capture Accuracy: +/- 2 counts with an additional 10
microseconds of variance
Notes: For digital servos, these points act as the PWM / ENBL outputs and
Alarm inputs. For Analog Servos and Aux axes, these points are input
only. The listed 0v pins should be normally used for the signal return.
