C7130 and C7120 C/Port Installation • 17
On the C7130, when color alignment is complete on a fine-tuned automatic alignment, all
three switches must be in position E or F. For a manually tuned system, at least one switch
must be in position 0 or 1. If these conditions are violated, the colors will be mis-aligned until
the switch positions are corrected.
Tuning Notes
Fiber C/Ports do not require any tuning.
Any C/Port, whether Auto-tunable or not, can be tuned manually by starting at switch
positions 1-1-1.
On normal restart, an Auto-tuned C7130 performs an Auto-tune cycle, then applies any
previously set fine-tuning. If the original blade or connecting cable is changed, the previous
fine tuning may not be optimal. Therefore, when blade or cabling changes are made, reset the
color switches to F-F-F to remove previous fine tuning adjustments, and retune if desired.
When a C7130 set to an improper manual or Auto-tune state is restarted, it comes up in the
manual tuning mode regardless of switch settings, and will not Auto-tune. To correct this,
reset the color switches to F-F-F for Auto-tune, or to 1-1-1 for manual tuning.
Automatic color tuning is normally superior to manual tuning. One reason is that manual
alignment allows the possibility of visual error. Another reason is that manual tuning may
conflict with the automatic adjustment built into some monitors. However, manual tuning may
give a better picture in some cases, such as with a poorly aligned display. When an Auto-tuned
system does not deliver satisfactory video performance, use manual tuning.
Using the C7130 Blade Reset Button
To restart the blade from a C7130, press and hold the Blade Reset Button for at least two
seconds to send a Reset signal to the blade. When the Blade Reset Button is pressed for less
than two seconds, a Reset signal is not sent. Instead, if the C7130 is connected to an R4300
chassis, the C/Port flashes its Link light to indicate connection to an R4300. If connected to an
R4200, nothing happens when the Blade Reset Button is pressed for less than two seconds. If
you are resetting a blade, allow the reset sequence to finish before pressing the Blade Reset
Button again.
Using the Blade Reset Button on Earlier C/Ports
The C7120 does not provide any circuitry to detect the chassis type. To restart the blade from
a C7120 or earlier C/Port, press the Blade Reset Button momentarily and then release it. Your
monitor will go black for several seconds while the blade resets. Allow the reset sequence to
finish before pressing the Blade Reset Button again.
