GPS Synchronized Miniature Time Code Generator, Model 6115G-8 provides an IRIG B time code output derived from GPS.  The time code output is synchronized with UTC time unless a time offset has been programmed.  A twelve channel GPS receiver automatically acquires all in-view satellites upon power up and locks an internal IRIG B time code generator to the GPS time reference.  If the GPS lock is lost the 6115G-8 will automatically switch to an internal clock and continue generating the output IRIG B signal.  No discernible change in the IRIG B output will occur due to this transition.  Additionally a battery backed up internal clock maintains time during power loss.  An external event may be time tagged by applying an Event Trigger to the Trigger Input.  The time of the event will be captured and stored until output via the serial port. The maximum event burst rate is 100KHz and the event buffer can store up to 127 events.

The 6115G-8 features a programmable time offset to convert the time from the GPS  receiver from UTC time to local time.  

The 6115G-8 has an asynchronous RS-232C port, which provides a means of configuring the unit, as well as reading the time, event, and location information.  The output messages for time/location and events are individually controlled.  The Time/Location message may be set to OFF or AUTO.  When set to AUTO, messages are sent at one second intervals.  The Event message may also be turned off, or may be set to respond only to a Query or set to send automatically until the event buffer is empty.

Included with the 6115G-8 is a CDROM containing a self-installing utility program for setting up the unit via a Graphical User Interface (GUI) from a Windows based computer via the COM port. The program will run on Windows 9x, 2000, NT, ME and XP operating systems

The 6115G-8 is housed in an aluminum enclosure, 7.5 inches long (including mounting flanges), 4.25 inches wide and 1.45 inches high.  All controls, connectors and indicators are on the front panel. 

The 6115G-8 is also available with built-in Video Insertion.  There are three versions available, the Model 6115G-8V2, Two Channel Video Inserter, the Model 6115G-8V4, Four Channel Video inserter and the Model 6115G-8V6, Six Channel Video Inserter.  An Inserted video time message may be positioned at any one of fifteen locations in the video frame as selected by a front panel switch.  The character size is also selectable, again by a front panel switch.  The time message positioning and size selection is independent for each video channel.
