Device is not PIN capable
From KB
This message will appear under two circumstances.
1 If you are trying to select the Debit prompt from the Sale screen while you are using either the Unimag or Walker Audiojack Readers
2 If you are using the Miura device to accept a Pin Debit Transaction and your processor is not able to accept a Debit transaction.
The only fix for this message is to run the transaction as a Credit transaction, not Debit
