5.23: IRIG-B Connections

IRIG-B is a standard time code format that synchronizes event timestamping to within 1 millisecond. An IRIG-B signal-generating device connected to the GPS satellite system will synchronize Nexus 1250/1252 Meters located at different geographic locations. Nexus utilizes an UNMODULATED signal from a satelite-controlled clock (such as Arbiter 1093B). For details on installation, refer to the User’s Manual for the satellite-controlled clock in use. Below are installation steps and tips that will help you.

Connect the (+) terminal of the Nexus Meter to the (+) terminal of the signal generating device; connect the (-) terminal of the Nexus Meter to the (-) terminal of the signal generating device.

Installation:

1.Set Time Settings for the meter being installed. From Communicator EXT, Device Profile, Click Time Settings. Set the Time Zone and Daylight Savings (Select AutoDST or Enable and set dates). Click Update Device Profile to save the new settings. (See the Communicator EXT User’s Manual for details.)

2.Before connection, check that the date on the meter clock is correct (or, within 2 MONTHS of the actual date). This provides the right year for the clock (GPS does not supply the YEAR).

3.Connect the (+) terminal of the Meter to the (+) terminal of the signal generating device; Connect the (-) terminal of the Meter to the (-) terminal of the signal generating device.

Troubleshooting Tip: The most common source of problems is a reversal of the two wires. Try reversing the wires.
