6. Frequently Asked Questions
This section describes problems that you may encounter while using HDR-80. If you have
any questions, please refer to related sections and follow all suggested solutions. If problem
still exists, please contact your distributor or the service center.
No. Problems Solutions
1. The connected monitor cannot
display 4K HDMI video sent from
the HDR. Check if your 4K monitor supports 4:2:2
because this is the only format that the HDR
unit supports. Please change a monitor if the
connected monitor supports 4:2:0 or lower
or connect the monitor to HDMI OUT 2 or 3.
2. The HDR unit cannot detect 4K
HDMI video. Please reboot your HDR unit or unplug the
HDMI cable then plug back in. If the problem
still exists, check whether your video source
format is 4:2:0 or DVI/HDCP, because they
are not supported by the HDR.
3. Can I record the video to two SSDs
at the same time? No, the HDR unit does not allow the user to
access the two disks at the same time. The
dual disk design is to allow the HDR to switch
to SSD2 to continue recording when the SSD1
is full. While recording, the system will
display an insufficient capacity error message
when the storage space runs out.
4. The HDR unit fails to receive the
12G SDI video over the 100 meter
cable. First check whether the cable is 12G SDI
compliant.
For example, if you are using an 100m Canare
SDI cable, you will then need to make sure
the cable is 5.5C UDH or above. If you are
using a 3G SDI cable, the maximum allowable
distance is approximately 70 meters.
Low grade cables have a transmission
distance of less than 1 meter so if you need
to send 4K SDI video over a long distance,
please first make sure your cable is 12G SDI
compliant.
5. Can I send video to and from the
HDR unit over long HDMI cables? Yes, you may send video to and from the HDR
unit over long HDMI cables but HDMI
Licensing Administrator, Inc. does not specify
the maximum transmissible HDMI cable
length which is entirely dependent on the
device capability and the cable grade.
For long distance transmission, we
recommend using cables approved by HDMI
Licensing Administrator, Inc. to ensure
quality of transmission.
