NB: If using the CC-300 with this unit, you must upgrade to the latest
firmware: CC-300 CORIOconsole firmware updates
Please also see C2-160, C2-260, C2-1000, C2-2000, C2-3000, 1T-C2, C2-7000
Series Windows Control Panel software (WCP) for the latest version

The above is a self-extracting file which includes the firmware data
file, plus the firmware programmer. You will need either:
1. a null-modem serial cable and a spare COM / RS232 port on your
computer (see RS232 connection / cable); or
2. an ethernet connection for both the C2-7000 series unit and your
computer, with the IP addresses set up correctly (you should be able to
'PING' the C2-7000 series unit).

Version 120: c25firmup_1.0.44_v120.exe
1. Made Lock H/V shift item accessible when in Lock & Mix mode as well as
Genlock mode.
2. Fixed C2-7100 Ethernet upload issue on newer boards.
3. Can now lock to a 525i/625i YUV / YPbPr source - but requires that
source is clean and jitter free.
4. Fixed CV/YC genlocking jitter issue on newer units.
5. Added advanced field swap / line offset adjustment to Adjust source
(set Advanced menus = On)
6. Changed description of some inputs to more closely match the physical
connector type.
7. Fixed bug where tlYUV setting for HD outputs did not restore on
power-up if saved.
8. Added transitions to Dual PIP and Independent modes.
9. Increased maximum transition time to 999.9 seconds and improved
transition time accuracy.

1. Improved colour quality for CV/YC/SDI inputs.
2. Improved fine-detail colour quality for CV/YC/SDI outputs.
3. Fixed problem where only Macro 1 would actually run (although others
would store, etc.).
4. Macro load/delete time (for button hold) increased to approx. 1s/5s
respectively in response to customer demand.
5. Improved sync separation for 720p 50Hz YPbPr sources.
6. Improved analog sync (RGBHV, YPbPr, YUV, etc.) input on RGB1/2/3 –
more accurate resolution detection.
7. In Switcher mode, blanking the output (using 'Output enable') now only
affects Program and not Preview.
8. Reduced jitter visible on very high resolution (UXGA and above) analog
RGBHV inputs.

1. Autoset for analog RGB (in Adjust sources menu).
2. Improved 1080i in/out performance when no zoom/shrink active.
3. Edge-blending now present - see Edge blending function and setup guide
4. 'Auto' mode in Adjust sources for RGB inputs now defaults to YUV
(instead of RGsB) if no analog sync detected.
5. 'Output res' changes (for changing the output resolution) now only
takes effect when no longer adjusting the value (i.e. when the brackets
stop flashing). This makes resolution changes much faster.
6. Revised EDID data (for DVI-D connection) to include chromaticity data.
7. Bug fixed where Z window (background image) was not updating during a
Takein Switcher mode, if nothing else had changed.
8. Improved fade transition in Switcher mode to help prevent 'Z
leak-through' if a background is present. As long as no Shrink value has
changed, and keying not active, leak-through will no longer be present.
9. Fixed occasional problem with 2nd output in independent mode.
10. CC-300 functionality improvements.
11. Fixed problem where (in Switcher mode) a non-valid signal could cause
a 'Take' to become instant.

2. Added Colour transient improvement & digital noise reduction to CV and
YC inputs (always active).
3. Fixed problem where EDID data for RGB3 input was not always correct.
4. Many extra resolutions added - so therefore some numbering will have
5. Added 'Output enable' in 'Adjust outputs' for fast blanking of output.
6. Greatly improved all image locking and centering functions - removes
the need for TL/BR changes in 'Adjust sources' for DVI, SDI and HD-SDI
