Important: Do not connect GND and SGND to different (external) ground references. GND and SGND are
internally connected through filtering circuitry which can be permanently damaged if subjected to voltage
drops over 0.8 V dc.
Note: To avoid electromagnetic interference when the reader is connected to a TCNM-ACBB1 connection
box, verify the jumper positions in the TCNM-ACBB1 as indicated in p/n 174477
