12.2 General troubleshooting for device recognition
1. Ensure all jumpers are correctly placed as outlined in the EVM User’s Guide. This includes ensuring
jumpers J2 and J3 are connected if using the battery stack/resistor ladder to supply power for the
EVM. Also ensure that SW1 is set properly to base or stack.
2. Ensure that the device lower in the stack is connected using its “High Side Comm” connector to the
higher device in the stack’s “Low Side Comm.”
3. Run auto-addressing and see if all devices show up in the top left dropdown menu. If a device does
not, the device may not be configured properly as described above and in the EVM User’s Guide.
