GUIDE TO INSTALLATION AND OPERATION
12 | HCO-1822
Video – Video Error alarm
This error is always ENABLED and the level set to 1, 2 or OFF. The
factory default value is level 1.
Use the slider to set the duration for which the error must
continuously exist before the alarm is flagged. The nominal range of
durations is 0.05 to 90 seconds. When durations ≥1 sec are
selected, there is an additional 0.5 seconds intrinsic to the error
detection algorithm that will prevent switching when there are nearly-
coincident errors at the two inputs.
The LED color is not configurable.
NOTE: This is the only error that can be triggered in the ASI
operating mode. All other errors will be disabled.
Video – Format Mismatch
The user sets an expected format for each input using the pulldown
in the control panel. The HCO-1822 compares this with the actual
format detected at the input, and flags an error if they do not match,
after a 0.5 second delay.
Formats listed in the pulldown are:
• 525
• 625
• 1080i 59.94 Hz
• 1080i 50 Hz
• 720p 59.94 Hz
• 720p 50 Hz
• SD
• HD
This error can be Enabled using the checkbox, and the level set to 1,
2 or OFF.
Use the LED Color pulldown to choose the color that will be
displayed by the status LED on the card edge when a Format
Mismatch error is detected. Choices are:
• Green, Yellow, Red, Flashing Red
