C2-2855 Frequently Asked Questions
Which input source can I genlock to?
You can genlock to any available input source.
If I’m using any of HDMI, YC, CV or PC/HD why can’t I select any of these for another layer?
Due to the hardware architecture it is not possible to use 2 of these I/O connections at the same
time. You can overcome this by using the DVI-U dongles to expand the I/O connectivity.
Does the C2-2855 accept 3G SDI level A and B?
C2-2855 only accepts 3G SDI level A only.

That’s correct you will get a black screen as you can’t display HDCP content over 3G-SDI or HD-SDI

resolution to PAL or NTSC which is (SD-SDI).

Which versions of HDMI can C2-2855 support?
The C2-2855 has support for the High-Definition Multimedia Interface (HDMI) to V1.4 on both
dedicated Inputs/Outputs
I have plugged an HDMI source into the DVI-U input via a dongle and I’m getting no audio?
The C2-2855 by default broadcasts its DVI capabilities using an EDID packet to the video
source. As DVI does not carry audio, this EDID packet does not say the unit supports it and
therefore when using HDMI you get no sound. Fix this by changing the EDID to HDMI; select
Setup, select Sources, select Inputs, select DVI-U, select Digital Settings, change EDID to
‘default HDMI’. Press and hold OK button to save settings and then power cycle the unit
I don’t understand how to select my keying color with Y, U, V
On the USB stick shipped with the unit, and in the user documentation there are some simple
guides that help you. The USB stick contains 2 helper images with U and V values to help
select your color. The reason for 2 is that SD video and HD video use different maths to
convert from the data to a picture, and this makes a difference when selecting your keying
values. The documentation contains a worked example for calculating your keying color

My output resolution changes when my Background source is removed
The unit only has 1 scaler. That scaler is always applied to the Primary layer. That means when
a Background is selected (and used), it determines the output resolution. If the background is
removed, the unit has to make its own decision and falls back to the current
Setup\Outputs\Video\Resolution\Resolution Index setting.
I am not hearing the audio I expect when setting the Live\Audio to ‘Follow Primary’ and my
Primary carries embedded audio?
With this setting the output audio will reflect the setting made for
Setup\Sources\Inputs\<connector>\Audio. It does not mean SDI video= SDI audio and HDMI
video = HDMI audio etc. This means it is possible to map any audio source (including mute)
against any video connector. If this mapping is incorrect, you will not hear the audio you
expect. Also see “I have plugged an HDMI source into the DVI-U input via a dongle and I’m
getting no audio?”
Where has my Digital Settings, RGB/YUV Settings, Signal Type=YC/CV menu gone
There is a restriction in the current software, some menus are only visible when the
associated source is connected. In the Case of inputs, the Digital Settings and RGB/YUV
Settings will only be present if a corresponding digital or analogue input is detected.
The YC/CV output signal type option will only be visible IF the output resolution is either PAL
or NTSC, as these connectors are not supported by any other resolutions.
I change between Primary sources and my video disappears?
In certain situations, if you change from a Primary source to another which is not present, and
your transition effect is NOT set to cut, rather than seeing the ‘On Source Loss’ video – the
transition effect will make the Primary disappear and the disconnected source will not appear.
I’m changing the position of my PIP/Logo and the numbers change, but the PIP/Logo doesn’t?
PIP and Logo placement is controlled using percentages in the current software. The position is
based on the center of the logo/pip. So if the PIP is 20% of the output resolution width, then
settings of < 10% and >90% will have no effect as this would move the PIP/logo off-screen which is
not possible. The origin for PIP/Logo placement is the top left of the output video.

I’m changing my Primary Layer size and it’s having no effect on the output video
The Home\Setup\Layers\Primary\Size setting only effects the output video when the Primary
layer is viewed in PIP mode
I’ve made a mistake, nothings working, how do I get back to something good?
Two things can be done here. The unit can be reset to factory defaults by pressing and holding the
OK, power and Back buttons for ~5seconds. This will reset all the menus to their factory settings.
This may get you back to a useable setup, if not. Access the Preset menu and ‘Load Default’ which
will give you a Primary of HDMI full screen, in Scaler mode, with an output of 720P60.
These 2 options can be swapped if necessary
YC input is not being detected on the DVI-U input
The YC input signal cannot be detected on the DVI-U port 'Auto' mode. You need to manually
select it by navigating setup/sources/inputs/DVI-U/Input Type and manually selecting YC.
Remember to save settings otherwise this changed will be lost on a power cycle.
