Triggering Recording from External Timecode
The PIX 250i can be configured to start recordings when incoming timecode begins rolling and stop
when it becomes stationary. This is generally referred to as Record Run timecode. The master time-
code device should be setup in this manner. To configure the PIX 250i to follow Record Run com-
mands:
1. Set Setup Menu option [Remote Control - Rec Start/Stop] to Timecode.
2. Make sure that the device that is sending timecode is configured to send stationary
timecode while stopped and running timecode while recording. To cause the PIX 250i
to stop recording when linear timecode signal is absent (disconnected), set Setup Menu option
[Timecode/Sync - Timecode Mode] to Ext TC (LTC Halt).
3. Some cameras do not send the correct timecode in the first few seconds of a recording, or
they send short bursts of timecode causing the PIX 250i to record short unintentional files or
incorrect timecode values. The [Timecode/Sync - Auto Record Hold Off] feature is designed
to eliminate these issues. When a hold off value is applied, the PIX 250i will begin capturing
the moment timecode begins rolling but will only go into record if a valid timecode signal is
present after the hold off time has elapsed.
Triggering from external timecode will not cause the PIX 250i to automatically stamp ex-
ternal timecode to recorded files. The timecode stamped to files is determined by the setting
[Timecode/Sync - Timecode Mode]
Triggering Recording from SDI Flag Bits
Start and stop flags embedded in the SDI signal from some cameras can be used to
start and stop recording of the PIX 250i. To enable this feature, set Setup Menu option
[Remote Control - Rec Start/Stop] to the SDI Flag option that refers to the manufacturer of the
connected camera. Setup Menu option [Timecode/Sync - Timecode Mode] must also be set to
Ext TC (SDI,HDMI).
GPIO (General Purpose Input / Output)
The 10-pin Phoenix connector provides six GPIO logic points. These can be used as simple-closure
inputs, and to drive LEDs or relays. The following table lists the pin assignments of the GPIO con-
nector.
Pin Function
- (-) Ground. Provides access to ground for triggering logic-low connections.
1 REC Input. Triggers PIX 250i record.
