Notes:
1. This is the same pinout as DIO-32F boards from National Instruments.
2. Pins 2, 4, 6, 8, 10, and 12 on the SCXI module connector are not connected.
3. RGND pins are connected to GND pins on the DAQDIO 6533 and on the adapter board. However, the shielded cable
does not connect these four pins from the DAQDIO 6533 to the adapter.
4. DIOA(0) on the SCXI module connector is tied to +5 V with a 100 k
Ω
resistor on the adapter board. This pin
connects directly to DIOA(0) of the breakout and DAQDIO 6533 connectors when you set SW1 for parallel mode.
When you set SW1 for serial mode, the adapter board inserts a buffer to redrive the module connector pin to the
breakout connector and DAQDIO 6533 connector.
5. DPULL is tied to +5 V with a 470
Ω
resistor on the adapter board.
