PTC-892 SOFTWARE INSTRUCTION SET (continued)
Encode modes
(continued)
^A7 01 37
Software bypass on: This mode does the same thing that
^A0 does.
^A8 01 38
Field 1 Transparent, Field 2 Transparent: This mode allows
information already on Field 1 and Field 2 to pass
un-touched. This is the factory default encode mode.
^A9 01 39
Field 1 Monitor, Field 2 Monitor: This mode allows
information already on Field 1 or Field 2 to be re-encoded. If
no information is on Field 1 or Field 2, the PTC-892 inserts
run-in clock and null bytes. This mode is good for removing
noise and chroma from line 21.
^A: 01 3A
Field 1 Opaque, Field 2 Opaque: This mode blocks all
information already on Field 1 and Field 2, and inserts run-in
clock and null bytes.
^ANx 01 4E
Field 1 Newswire Mode, Field 2 Transparent: This mode
accepts a simple ASCII feed and the encoder itself inserts
Field 1 command codes for three-line roll-up captions, while
information already on Field 2 to pass un-touched. A
“time-out” feature will insert the “erase displayed memory”
command code after “x” seconds without a new input. (“x”
may be any number from three through fifteen. For numbers
greater than nine use hexadecimal letters A through F.
Default time is fifteen seconds.) To exit Newswire mode,
you must put the PTC-892 into a different encode mode.
^AR 01 52
Soft Reset: A soft reset of the PTC-892, by loading default
values for encode, decode, and recovery modes also clears
XDS RAM, without causing glitches in the video. This will
not reset I/O formats, bauds rates, pedestal, or weather lift
like the hard reset does.
^AS 01 53
Software bypass off: Returns the PTC-892 to the last
encode mode before Software bypass on (^A0) was selected.
Changing encode modes will also accomplish the same
thing.
^Anx 01 6E
Field 1 Newswire Mode, Field 2 Transparent: This mode is
the same as ^ANx except that this is a two line roll-up
caption mode.
