The GPS Options tab in CompuSync sets how often the computer's clock is updated from the GPS or CompuSync Receiver. It can be found from the main Options menu of CompuSync.
From the Options menu, click the GPS Options tab.
To set the GPS Receiver as the time source, select the check box Enable GPS as time base. When enabled, CompuSync will synchronize the operating system time to the GPS time at the interval specified.
When this setting is enabled, CompuSync accesses the GPS at the interval specified, independent of the timserver settings selected (e.g. Manual, Periodic, Auto).
Set the Sync frequency in minutes. Sets the number of minutes between GPS time readings. Updating the operating system clock from the GPS stabilizes a system with erratic time keeping.
Set the SyncTime to continuous, as the GPS should be continuously sending data.
To connect to an external timeserver when GPS is unavailable, select the check box Use external timeserver as a backup when GPS is unavailable.
This is not recommended as Internet time servers may not be synchronized to the Primex System.
CompuSync will get the time from a backup external timeserver specified in the settings in the Timeserver tab.
In the Timeserver tab you can choose to use either an Internet based timeserver or contact the NIST directly via modem (Direct Modem).
Set the warning level under the Settings tab to determine when the backup timeserver should be used.
