An encoded test message may also be selected from
the front panel, showing Link as the manufacturer
name, model number and firmware version. A total
of nine data channels for video line 21 may be
selected: CC1, CC2, T1, and T2 in Field 1 along with
CC3, CC4, T3, T4, and XDS in Field 2.
SD SDI PDP-886. When the PDP-886 is used with
closed caption software, the unit inserts Closed
Caption data into a component serial digital data-
stream. There are two encoded serial digital outputs
plus four SD Analog NTSC/PAL outputs. One set of
the SD Analog outputs are open caption and the
second SD Analog set of outputs are closed caption.
A built-in EDH (Error Detection and Handling)
processor can monitor the incoming signal for
impairments and insert new EDH data. This function
will insure that the output EDH Checksum will reflect
the new Line 21 waveform. An optional internal
telephone modem is available for each processor.
Three LED’s on the front panel indicate RI, OH, and
CD.
Serial control is handled via two RS-232/422 ports,
selectable by an internal switch. A front panel LCD
indicatesEncode, Standard, DecodeandBaudRate.
There are two microprocessors incorporated, two
ports for each microprocessor (RS-232/422 and
modem). The SD SDI signal will bypass in case of
AC failure on one output.
