Digital IO - Test Case

Initial Setup

In order to proceed through the test case, first of all delete the Scopy *.ini file (saves previous settings made in Scopy tool) from the following path on Windows: C:\Users\your_username\AppData\Roaming\ADI .

Open the DigitalIO instrument. The interface should look like the picture below:

Press multiple times on the “Run” button to check if the instrument works.

Description	Test Steps	Expected Results
Checking individual digital pin state	1. Set DIO 0-7 and DIO 8-15 as individual pins	The interface should look like in the “Step Resources” picture (left side).
	2. Set channel 0 as output	The interface should look like in the “Step Resources” picture (left side).
	3. Set channel 7 as input	The interface should look like in the “Step Resources” picture (left side).
	4. Connect digital channel 0 to channel 7 via wires.
	5. Change the logic state of channel 0 (0/1) multiple times and monitor channel 7 state.	When channel 0 is set to logic one, channel 7 will be automatically set to logic 1. When channel 0 is set to logic one, channel 7 will be automatically set to logic 1.
	6. Connect the channel 0 to voltmeter and channel 7 to the positive power supply.
	7. Set channel 0 to logic state 0.	The interface should look like in the “Step Resources” picture (left side).
	8. Monitor the voltage value via voltmeter.	On the voltmeter the voltage displayed is be between -0.050V and 0.4V.
	9. Set channel 0 to logic state 1.	The interface should look like in the “Step Resources” picture (left side).
	10. Monitor the voltage value via voltmeter.	On the voltmeter the voltage displayed should be between 2.9V and 3.4V.
	11. Set positive power supply to voltage level between 0V and 0.8V.	The interface should look like in the “Step Resources” picture (left side).
	12. Monitor the channel 7 logic state.	Channel 7 indicates logic 0 level.
	13. Set positive power supply to voltage level between 2V and 3.3V	The interface should look like in the “Step Resources” picture (left side).
	14. Monitor the channel 7 logic state.	Channel 7 indicates logic 1 level.
	15. In step 2 replace by turn channel 0 with channels from 1 to 6 and from 8 to 15. Then, for each replacement repeat steps from 3 to 13.
	16. In step 2 replace with channel 7 and in step 3 by turn channels from 0 to 6 and from 8 to 15. Then, for each replacement repeat steps from 4 to 13.

Set DIO 0-7 and DIO 8-15 groups as Group pins:

Description	Test Steps	Expected Results
Checking grouped digital pin states	1. Set DIO 0-7 and DIO 8-15 as Group pins.	The interface should look like in the “Step Resources” picture (left side).
	2. Connect DIO 0-7 to DIO 8-15 via wires.
	3. Set DIO 0-7 as output.	The interface should look like in the “Step Resources” picture (left side).
	4. Set DIO 8-15 as input.	The interface should look like in the “Step Resources” picture (left side).
	5. Set DIO 0-7 at value 0.	The same value of DIO 0-7 group must be displayed on the DIO 8-15 group.
	6. Set DIO 0-7 at value 128.	The same value of DIO 0-7 group must be displayed on the DIO 8-15 group.
	7. Set DIO 0-7 at value 170.	The same value of DIO 0-7 group must be displayed on the DIO 8-15 group.
	8. Set DIO 0-7 at value 255.	The same value of DIO 0-7 group must be displayed on the DIO 8-15 group.
	9. Set DIO 0-7 as input and DIO 8-15 as output. Repeat step 2.	For each value set for the DIO 8-15 group, the same value must be displayed on the DIO 0-7 group.
