MIL-STD Miniature IRIG B Timecode Generator 6115G-8S-N

The ITS Model 6115G-8S-N is a MIL-STD miniature IRIG B Timecode Generator with NMEA messaging and provides AC and DC IRIG B timecode Outputs. The internal timecode generator is synchronized with UTC time derived from GPS and or an IRIG B reference input as selected by the operator. However, if the signal is lost the 6115G-8S-N will automatically switch to an internal clock and continue creating the output IRIG B signal. No massive change in the IRIG Output will occur during this transition.

Firstly, 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.

Secondly, the 6115G-8S-N has an asynchronous RS-232C port. It enables configuring of the unit as well as reading the time, event and location information and NMEA messages. 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. A self-installing utility program for setting up the unit on Windows via a Graphical User Interface (GUI) is provided.

Thirdly, the 6115G-8S-N is housed in an aluminium enclosure designed to meet shock, vibration and EMI requirements of Defence Aircraft. With all controls, connectors and indicators on the front panel. It is 19cm long x 10.80cm wide and 3.68cm high.
