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 congured 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 rst few seconds of a recording, or

they send short bursts of timecode causing the PIX 250i to record short unintentional les or

incorrect timecode values. The [Timecode/Sync - Auto Record Hold Off] feature is designed

to eliminate these issues. When a hold o 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 o 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.
