6.1.18 When the caption decoder is set to XDS, the text sometimes
disappears momentarily.
This behavior is intentional, and does not represent a problem with the
encoding of XDS packets. In XDS display mode, the internal caption
decoder has been configured to flush its memory and reacquire all XDS
data every 16 seconds. This makes it easy for the operator to see if a
particular XDS packet has been removed from the data stream altogether.
Of course, if the packet has been replaced with another packet of the same
type, the display will be updated immediately.
6.1.19 Captioning waveform is at the wrong voltage level when
converted to analog video.
SDI to analog specifications state that there is to be no setup added to line
21. Regardless, some conversion equipment does add 7.5 IRE to line 21
when converting to analog. To correct for this, enable the CAPTION SHIFT
feature of the encoder. Please refer to your manual under the heading
CAPTION SHIFT or CAP'N SHIFT for more details.

6.1.20 When should I use "Reset to Factory Defaults"?

Factory Reset should not be used lightly. It is intended primarily for use
when Evertz technical support personnel are assisting an operator with a
problem. The Factory Reset could also be used when the encoder is
placed in a particular undesirable mode of operation and the operator is
highly unsure as to how to resolve the situation. Note that any special
features that have been enabled by the operator, such as baud rate
settings or the VBI bridge, will need to be reconfigured after a Factory
Reset.
6.1.21 I cannot get the VBI Bridge or Port Passthrough feature to work
correctly.
Use of the VBI Bridge or Port Passthrough features requires two
8074/8084/8084AD units. Make sure that the serial baud rate and parity of
both is the same for the inter-connected ports.
VBI Bridge extracts caption data from the line 21 waveform and passes it
directly to another caption encoder to re-encode.
