CANNOT GENLOCK VIA REDCAST MODULE
SYMPTOMS
Cannot genlock the camera when a genlock device is connected to the REDCAST Module.
The GEN indicator does not illuminate green.
POTENTIAL RESOLUTION
Ensure that each of the following has the same frame rate:
Recording Frame Rate (Sensor Frame Rate)
Project Time Base
GENLOCK NOT IN SYNC WHEN USING LONG CABLES
SYMPTOM
The camera is receiving an incoming genlock signal, but third-party broadcast infrastructure (such as a switcher
or video ingest equipment) indicates that the video does not align with the genlock signal.
Since this issue occurs when the video reaches third-party infrastructure, the camera does not indicate any
errors due to this issue.
EXPLANATION
If using long cables to connect the REDCAST Module to a genlock device or the video ingest point, the video
may be delayed once it reaches the video ingest point.
For example, using a 1 km fiber optic cable to connect the REDCAST Module to a switcher creates a 2 km
round trip for the video signal. This results in a round trip delay of about 10,000 nanoseconds. For 59.94 FPS,
one pixel time is 6.73 nanoseconds, so the round trip delay is about 1485 pixels.
POTENTIAL RESOLUTIONS
Offset the signal in the broadcast truck using third-party infrastructure.
Offset the video signal in-camera to align it with the genlock signal. For more information, go to

CAN ONLY SELECT QUADRANT AS OUTPUT
SYMPTOM
In firmware v5.3, the only Output option in the REDCAST menu is Quadrant.
EXPLANATION
This is normal behavior. In firmware v5.3, the only option in the Output menu is Quadrant. To access additional
options, upgrade the DSMC
®
firmware to v6.0.
