Analog Output Option Installation
Video Format
1. Remove the 064815 Analog Output mezzanine board (the small
mezzanine on top) from the 064912 Analog Output Support mezzanine
board. This entails removing four (4) screws around the perimeter of
the Analog Output board and gently pulling the board straight up.
When you have removed the 064815 Analog Output mezzanine board,
turn it over to view the component side.
2. Locate jumpers J5, J6, J9, and J11 on the Analog Output board and set
all four jumpers to either a for Color Difference format, or b for RGB
format. See Table 2-1 for details.
3. Locate jumpers J4, J8, and J10 on the Analog Output board. Refer to
Table 2-1, and set each jumper to the desired analog output format.
Note that some formats require installing two jumpers on J8 and J10.
Extra jumpers are stored in an inactive socket, J7. If you are changing to
a format that uses one jumper at J8 and J10, store the extra jumpers at
J7. If you lose a jumper, you can make a suitable substitute from a short
piece of 24 gauge solid tinned copper wire.
4. Carefully reinstall the Analog Output board onto the Analog Output
Support board, making sure all connector pins match up with their
sockets correctly so that no pins become bent. Secure the Analog
Output board using the four screws that you removed earlier.
