9.4 mtx
The two first matrices change sizes to suit the AES port directions but both have 64 sources.
• mtx 0 is de-multiplex source control.
• mtx 16 is multiplex timeslot control.
• mtx 32 is used to report the SDTI input in use. 0 is the electrical input, 1 is the optical
input.
• mtx 33 is used to indicate that the Master clock mode is active.
• mtx 34 is used to set the SDTI input selector mode. 0 is Auto, 1 is fixed to electrical, 2 is
fixed to optical.
9.5 pin and lsr
The optical option parameters and status are read from the installed Nevion video SFPs
9.6 pwr
The pwr blocks from 0 to 2 list the levels of the power supplies as measured by the micro-controller.
• 0 is digital 1.2V
• 1 is the frame 5V
• 2 is digital 3.3V
The frame supply is measured after the module fuse and filtering.
9.7 vmon
The vmon block is a video stream analyser block which can identify a number of different errors
in the video frame. The info page shows the errors that occurred since the last GYDA update with
red.
Errors that will be present as a result of other errors are masked out to allow the user focus to see
the most important error. i.e. If the lock error is active (red), the other errors will be green.
The block has an error counter with accumulates the number of video frames that have had errors.
The counter may be reset on the info page.
The different errors may be masked out individually by the user in order to isolate certain events.
The vmon block is configured on the conf page but the error mask is only shown after the black
’pulldown’ triangle has been clicked on. The masking effects the counter as the vmon block no
longer sees the error. Masked out errors are shown as grey blocks on the info page.
The signal integrity alarm will be triggered if the error parameters shown on the conf page are
