    Introduction Tankvision Multi Scan NXA83B Introduction The Multi Scan NXA83B is a configurable system designed for tank gauging and tank inventory management systems. Redundant operation with a pair of Multi Scan NXA83B linked together is supported, so that only one NXA83B will poll the gauges. The other Multi Scan NXA83B will automatically update its database with live data from the active Multi Scan NXA83B.

Ensure that COM 7 and COM 8 are NOT selected as "In Use" as either Host or Slave ports. Connect a Serial Cross-over lead from COM 7 on one Multi Scan NXA83B to COM 8 on the other for both Multi Scan NXA83B.
