box for the RS422 data outputs. The multiplexing box will combine and transmit the received
RS422 data from each gradiometer on a single Ethernet connection to an external laptop or

approximately 8 hours.
The multiplexing box has a removable lid for use during storage and transport.
The Network LED indicates that the system is connected to a network.
The Low Power LED flashes to indicate that the battery is nearing the end of its charge. Battery
life remaining after this point is dependent upon the number of gradiometers in use.
The External Power Input connector allows an external battery to be connected to the unit, if the
internal batteries become exhausted. This feature is currently under development.
