Configuration Dip Switch Settings
The 9018 has four 4 segment dip switches mounted on the forward edge of the PCB (Fig 4.); one for each
converter. These configuration switches provide the capability to set the 9018 converter to display a color bar
test pattern, turn setup on or off, and turn the chroma on or off. The switches work identically for each converter
and function as follows (Fig. 5).
Output Analog Video Gain Adjustment
To adjust the output amplitude of the analog composite output, use the potentiometers located on the front of the
card next to the 4 position configuration switches (Fig. 4). Each converter has one adjustment potentiometer
labeled "A" for the "A" converter, "B " for the "B" converter, etc. Turning the adjustment clockwise increases the
output amplitude, while counter-clockwise rotation reduces the output amplitude.

Color Bar Test Pattern: ON (up) (requires valid SDI input)
VBI Enable: ON at all times regardless of Switch setting
Setup: ON (up) or OFF (valid when in NTSC only)
Color Enable: ON - turns Chroma on, OFF = Chroma off
