MADE IN THE USA
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 data­stream. 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.
Serial control is handled via two RS-232/422 ports, selectable by an internal switch. A front panel LCD indicates Encode, Standard, Decode and Baud Rate. 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.
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.
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.
