MIL-STD IRIG B Timecode Generator 6115G-8SA-N

The 6115G-8SA-N is a MIL-STD GPS Sync IRIG Timecode Generator that outputs time, position, NMEA 0183 GGA and NMEA GSA Sentences via Serial Port.

Used in Broadcasting, Defence and many other Industrial Applications where a time reference is required

The ITS Model 6115G-8SA-N is a MIL-STD GPS Sync IRIG B Timecode Generator that provides 3 buffered IRIG B122 timecode outputs.

Firstly, the internal timecode generator is synchronized with UTC time derived from GPS. When a GPS signal is not available the unit will switch to an IRIG B reference input. If neither are available, it will automatically switch to an internal clock and continue generating output IRIG B signals.

Secondly, the 12 channel GPS receiver automatically acquires all in view satellites on power up. It locks the internal IRIG B timecode generator to the GPS time reference. If no GPS signal is present, the unit may be locked to an applied IRIG B time reference (via time zone offset). The internal clock has a battery backup. Therefore, it maintains time during power interruptions.

Thirdly, the 6115G-8SA-N has an asynchronous RS-232C port. It enables configuring of the unit as well as reading the time, event and location information. The output messages for time, location and events are individually controlled and may be set to OFF or AUTO. When set to AUTO messages are sent at one second intervals. It comes with a self-installing Windows based utility program for setting up the unit via Graphic User Interface (GUI) via the COM port.

Finally, the 6115G-8SA-N is housed in an aluminium enclosure designed to meet shock, vibration and EMI requirements of E-2C Hawkeye aircraft. All controls, connectors and indicators are accessed via the front panel. It is 19cm long x 10.80 cm width x 5.08 cm high
