5.3.17: IRIG-B 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® meters located at different geographic locations. The Nexus® meter utilizes an
unmodulated signal from a satellite-controlled clock (such as the 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.

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 Time. Click Update
Device Profile to save the new settings. (See Communicator EXT User's Manual.)
2. Before connection, make sure that the meter is set to the right year (IRIG-B 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.
