Novatel DL-V3 user manual Log Triggers, Trigger Description

DL Explorer	Chapter 4
Select a destination from the Port list:
• COM1, COM2, COM3	Send this log through a receiver COM port
• AUX	Send this log through a receiver AUX port
• USB1, USB2, USB3	Send this log through a receiver USB port
• FILE	Save this log to the receiver’s CF card
• NO_PORTS	No port specified
• THISPORT	Current COM port

If the group is intended for use in a stand-alone mode of operation, choose FILE to save the logs to the DL-V3’s internal CF card. You can save ASCII or binary format logs to the FILE destination.

Choose a log output format from the Format list, ASCII or binary.

The trigger and period settings can be edited by using the fields in the Trigger and Period sections of the Logs tab.

A log’s trigger and period information is what determines when and how often the DL-V3 receiver collects that log’s information. For example, if the trigger and period for the compressed range measurements log (RANGECMP) is set to OnTime 2, the receiver logs compressed range measurements every two seconds. For 2 Hz (twice per second), use an OnTime 0.5 trigger.

To edit trigger information for a particular log, first select a trigger from the Trigger drop down box.

The Period drop down box appears dim unless OnTime is selected as the trigger. In this case, you can edit the number of seconds directly or choose a time period from the Period drop down box. Table 10 explains your choices.

	Table 10: Log Triggers
Trigger	Description
ontime	You specify when the receiver should collect the information. For example, if you
	specify On Time 5, the information is collected every 5 seconds.
onchanged	Output only if the message changes. For example, if you select the almanac log
	(RAWALMB), you can choose the On Changed option so when a log group is run,
	the receiver collects almanac information once and not again unless the almanac
	information changes.
once	Output only the current message.
onnew	Output when the message is updated (not necessarily changed).
onnext	Output only the next message.

Click on the Add button to add the log details to the group. Continue to add logs until your group contains the logs you want. To remove a log from the group, select the log in the Logs table, and click on the Remove button.

To edit a log in a receiver group, select it, change the settings and click on the Add button again. The log appears twice in the table. Select the log with the old settings and click on the Remove button.

Click the OK button to save your changes or the Cancel button to discard your changes. The logs you have selected are displayed along with their descriptions, default destination and interval settings.
