Troubleshooting Tamper Error

POS Communication
If you experience problems with POS communication, verify if the POS two-wire port on the
HIP Board (M07895A001) is connected to the POS two-wire.

This LED (D6) will be lit if the
two-wire to the POS is reversed.
When installing the FlexPay EMV CRIND in an existing site equipped with Bulloch POS, the
POS must be reprogrammed to identify both side 1 and side 2, as side 1. If this change is not
made, the POS will not download screen definitions and graphics properly to the FlexPay
EMV CRIND.
Pump Communication
If you experience problems with pump communication, verify if the pump two-wire port on
the HIP board is connected to the pump two-wire port on the Pump Control Node (PCN)
board.
