6.1.14 Why doesn't my caption encoder have this button/LED/menu
item?
The manual describes more than one model of Evertz closed caption
encoder. These units are similar but different. The manual attempts to
describe the product features "where applicable" without complicating the
text with model exclusions where this is fairly obvious.
Evertz is constantly upgrading our products to increase functionality and
reflect market demands. Most product improvements to a particular model
are firmware upgrades, which can immediately benefit customers with units
in the field.

6.1.15 How can I block upstream captions?

Depending on the user's specific needs, there are many ways to
accomplish this. If all upstream captions are to be blocked, the
recommended approach is to issue the serial port commands ^A6 F1 and
^A6 F2 to place both Field 1 and Field 2 into NULL STATE. Another
solution is to place the Closed Caption Encoder in FIELD mode of
operation from the front panel Engineering menu.
If only a particular data channel is to be blocked, such as Text Channel 2,
use STREAM mode of operation, and execute the serial command ^A6 T2
to place this particular channel in NULL STATE. To block all upstream XDS
material, issuing ^A6 TX will put only the XDS stream into NULL STATE.
Presently there is no way to block specific XDS packet types, unless these
are being replaced with updated packets of the same type by the caption
encoder. If an entire field is to be blocked, use ^A6 F2 to place all of Field 2
in NULL STATE.

6.1.16 How can I pass upstream captions?

If upstream captions are being blocked, either the Closed Caption Encoder
is in FIELD mode, or the user's captioning software has failed to relinquish
control of the encoder so upstream captions may pass.
The recommended solution is to switch the unit to STREAM mode of
operation.
If captioning software is leaving the unit in DIRECT STATE or REAL TIME
STATE or NULL STATE when it is sitting idle, this issue must be resolved
in the caption software itself.
