Chapter 2: Operation
Internal Jumper
An internal jumper block with 3 jumpers determines the offset to Pedestal for NTSC. For
most instances, the factory default (all jumpers in place) will be the proper setting.
NOTE: If you will be using the GEN10 only to generate HD signals, or SD NTSC signals with Setup, no
jumper changes are required. Configuration is accomplished using the external DIP switches.
Internal jumper settings are:
• Jumper 1 installed (default): NTSC with Setup (54 mV pedestal offset)
• Jumper 1 removed: NTSC without Setup (no offset)
NOTE: Jumpers 2 and 3 are ignored—installed or not, they do not affect operation.
To access the internal jumpers, remove the four Phillips screws securing the back side of
the case (the side having the DIP switch access hole in it). Once the case cover is
removed, jumper positions 1 through 3 are clearly marked on the circuit board next to
the jumper.
