Checking if EEPROM is present on UUT...EEPROM is not present on UUT Count of I2C devices in range 0x20-0x27 on UUT = 1 Detected MCP23008 Select the board type (Other) 1 - I2CIO8 board 2 - I2CIO8X board Select board >
- Select 1
Init I2CIO-8 card C=Card Tests, D=Direct, E=EEPROM, I=access Internal DIGIO32
Running Loopback Card Test
- Use loopback cable
- Select Card Tests = "C"
- Select Run Tests = "T"
- Observe test results
L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Test, X=eXit sub-menu Testing UUT = I2CIO-8 Test PASS = 1, FAIL = 0
- Hit ENTER to display menu
L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Test, X=eXit sub-menu
Running Internal Tests
- Remove loopback cable
- Select Card Tests = "C"
- Select Run Tests = "I"
- Observe test results
L=Loop/S=Single, T=Test, B=Bounce LEDs, I=UUT Int'l Tests, X=eXit sub-menu UUT Internal card tests Test PASS = 2, FAIL = 0
- Hit ENTER to display menu
