Note: ‘nc’ denotes a “not connected” connector pin.
Note: MV-801 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 Example: Driving LEDs from the GPI Outputs , on page 20,
for an example of how GPI outputs can be used to drive LEDs.
Note: MV-801 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.
