3.2 DEVICE INSTANCE

It is possible to install 16 3420 AC Monitors on a NMEA2000® network so they need to each have 

a unique Device Instance Address. The Device Instance of each unit is set by turning the small 

rotary switch with a small screw driver. Valid Device Instances range from “0” through to “F”.

NMEA2000® Parameter Group Numbers (PGNs)

Note: The “line to line” voltage values on PGNs PGN127747, PGN127748 and PGN127749 are 

calculated from “line to neutral” voltage (not available on single phase, VLL = VLN • 2 for 

2-phase and VLL = VLN •  for 3-phase setup).

Note: The frequency values on PGNs PGN127747, PGN127748 and PGN127749 are the same as the 

system frequency. They are not measured on each phase separately.

Note: The power values on PGNs PGN127744, PGN127745 and PGN127746 are calculated from 

the measured voltage and current values (P = U • I).
