The Dcode Syncbox Time Code Generator is designed to work with the Dcode Time Code Slate allowing complete freedom from cables. It is great for concerts where transmitted time code is not feasible. The Syncbox generates all common time code formats. It can be jam set from an external time code source or internally set and used as a stand-alone generator.Features:Generates time code from SMPTE/EBU at: 24, 25, 29.97 and 30 fps, 29.97, 30 drop frame.Generates time code set from GPS at: 24. 25, 29.97 df and 30 fps.Time code out: The local mode starts at (00:58:30:00) allowing time to set hours before the roll  over of the next hour.User bits displayed in the local mode are (00:00:00:XX) where XX indicates the internal frame rate setting.  The user bit hour position automatically increments after 24 hours.The internal LED strobes at the selected frame rate when not jammed for 10 minutes after turn on. The  strobe can be used to chekc film shutter speed.The output voltage has been increased to drive time code film cameras and can be used as a low cost Master ClockAn optional Temperture Compensated Crystal Oscillator (TCXO) gives the SB-2 GPS an outstanding stability of +/- 1 PPM from - 40C/F to +85C/185F.GPS/Time code in: The generator is jam set from external time code ot GPS signal when the power switch is turned on. Jam is indicated by a short once per second pulse that continues when the signal is unplugged.The SB-2 can cross jam time code. Time code is set on the 00 frame and the output corresponds to the frame rate switch setting.Specifications:Size: 4.75" x 2.3" x 1.0"Weight 4.8 ozsBattery life: Approximately 60 hours with an alkaline battery.Power: 6 to 18 volts at 7 ma external or battery.Stability: Standard +/- 3PPM from -10C to +60CInput: Reads down to 0.3 volts (-10db)Accepts RS232 data in the GPS mode.Output: 2.5 volts peak into a 600 ohm load.Optional TCXO +/- 1PPM from -40C to + 85c
