Note:
‘nc’ denotes a “not connected” connector pin.
Note:
MV-800 GPI outputs
- Open collector outputs. Require external
pull-up resistors of value between 10 k
Ω
and 100 k
Ω. Each output can
sink up to 100 mA.
•
“+5 Vdc Out” pins are provided on the connector for this
purpose.
•
Maximum voltage, +5 V.
•
See Section 2.2.4 "Example: Driving LEDs from the GPI
Outputs" for an example of how GPI outputs can be used to
drive LEDs.
Note:
MV-800 GPI inputs
- Inputs have weak internal pull-down resistors.
•
Can be driven by input voltages of up to +5 V.
•
A logic “low” input is represented by an input voltage below
+0.8 V.
