After connecting a different Model 4404-16, select Change Serial Number
from the Tools menu and select the correct serial number from the drop-
down list. If this is a new counter, enter in the serial number.
Two different types of triggering are available to get the counts from the
Model 4404-16 Counter. GPS triggering uses the NMEA RMC message to
trigger a reading from the Model 4404-16 every one second. When using
the Model 4404-16 when a GPS signal is not available, for example when
calibrating the instrument inside Internal triggering can be used. This uses
an internal one second timer in the software to trigger a reading from the
Model 4404-16.
