4. Configuration
Setting Jumpers and Switches on Cards and Card Sets
There are three 8-position DIP switches on the AVC output card (EM0433), labeled S1, S2 and S3.
Switch S2 is not used. The S1 and S3 switches (labeled ‘USER SETTINGS’) configure each output
for the correct NTSC output format (pedestal or no pedestal).
The AVC input card feeds NTSC signals to the AVC output card. All 16 outputs on each output
card must have pedestal settings that match the pedestal settings on the AVC input card. For exam-
ple, if the input card’s S1-1 is set to ON, then the output card’s S1 and S2 must have all 16 switches
set to ON. Refer to the silk screen markings on the AVC output card to identify and set switches to
their proper positions. Do not use markings on the actual switch bodies.
If signals fed to the AVC output card originate from SD input cards, then each output can be config-
ured for pedestal or no pedestal (NTSC-M or NTSC-J) composite outputs. DIP switches S1 and S3
have no effect when handling PAL signals.
Note Attempting to convert NTSC-M signals to NTSC-J signals or vice versa results in
large Chroma/Luma gain errors.
