Cause

Auto-Detect Errors stem from the PIN Pad such as an SP30 connecting to a terminal like an A920. 

Resolution

1. Turn off the Terminal
2. Remove the PIN pad cable and reseat both ends firmly. 
3. Confirm with the Merchant if they are using a genuine PAX PIN PAD cable. (Should have come with the terminal)
4. Restart the Terminal.
5. Run a Test Transaction. 

If the Above steps do not resolve:

1. Review the file build for the A920 in BroadPOS/PAXSTORE
2. In The File go to the MISC Tab > Peripherals Features
   1. Pinpad Type should read as External
   2. External Card Read should read as Auto
      
   3. If a Correction is needed please edit and push the file parameters
