We tested 1 FPR here nad found that one of the fingerprint readers had a problem - that the TD+ and RD- on the controller unit was swopped around on the FPR Controller unit. The D11 Green LED on the UCM/Access was permanently on when the JP1 KA/KB is connected, and the led goes off when the terminal block is disconnected
When the KA/KB on JP1 is reversed by plugging the terminal block in the reverse direction then the communications between the UCM and FPR started to work.
Another FPR that we have here did not have this problem and the TD and RD terminals are correct
Can you check if this is the case with your FPR on your bench? The D11 Green LED would be permanent on in this case
We will send one correct FPR and UCM to you with the wires intact as we used to test.
