be conigured to record only when running timecode is present on HDMI input. The device that is
sending timecode to the PIX recorder must be conigured to send running timecode when recording
and stopped timecode when not recording (oten referred to as “Rec Run”). To make the PIX record
-
er record automatically when running timecode is sensed on the timecode input:
1. Set Setup Menu option
System

to
Timecode
2.
Make sure that the device that is sending timecode is conigured to send stopped timecode
while stopped and running timecode while recording.
Triggering from external timecode will not cause the PIX 240i to automatically stamp external timecode
to recorded iles. The timecode stamped to iles is determined by the seting

Triggering Recording from SDI Flag Bits
Start and stop lags embedded in the SDI signal from some cameras can be used to start and stop
recording of the PIX 240i. To enable this feature, set Setup Menu option
System
Rec Start/Stop
to
the
SDI Flag
option that refers to the manufacturer of the connected camera.
LANC
The LANC protocol can be used to start and stop recording of the PIX. A standard LANC controller
can be plugged into the 2.5 mm LANC connector on the right panel of the PIX recorder. When Setup
Menu option
System
Rec Start/Stop
is to
LANC In
, the PIX recorder will follow commands from
the LANC controller. LANC commands recognized by the PIX recorder are Start and Stop recording.
To send LANC commands from a controller to both a camera and a PIX recorder (or to use more
than one PIX recorder), parallel the LANC signal with a Y-cable running to both the camera and the
PIX. Set the Setup Menu option
System
Rec Start/Stop
to
LANC (parallel)
for any paralleled PIX
units.
Switch Contact Closure
The 2.5 mm LANC connector can alternatively be conigured to function as a standard GPIO logic
connection by seting the Setup Menu option
System
Rec Start/Stop
to
Switch Closure
or
Switch Momentary
. When in either of these modes, the 2.5 mm TRS “LANC” connection is no
longer used as a LANC input and the recorder will no longer function with a LANC controller. The
wiring of the TRS connector is:
• Tip: Switch Input
•
Ring: +5V LED voltage output (for illuminating an LED light for record tally)
•
Sleeve: Ground
When the Setup Menu option
System
Rec Start/Stop
to
Switch Closure
, recording will begin
when the Switch Input (tip) is connected to ground (sleeve) and recording will stop when the Switch
Input (tip) is disconnected from ground (sleeve). When the Setup Menu option
System
Rec
Start/Stop
to
Switch Momentary
, recording will begin when the Switch Input (tip) is connected to
ground (sleeve) and recording will stop when the Switch Input (tip) is connected to ground (sleeve)
a subsequent time.
To use the LED output, connect an LED between the 2.5mm ring and sleeve with a series resistor.
The anode (+) of the LED should connect to the ring and the cathode (-) to the sleeve. A good starting
point for the resistor value is 220i ohms, but the value depends on the particular LED used. The ring
is internally connected to 5V when recording (and to 0V otherwise) with a series 100 ohm resistor.
