5.1.2 Dipswitch
Settings
Configure the FC-7402 unit by setting the 8 dipswitches, as Table 3 defines:
Table 3: Dipswitch Definitions
Dipswitch
Set as follows:
1 RGB
ON for RGB, OFF for YUV
2 VBI
1
ON to enable Vertical Interval Blanking; OFF to disable
3 PEDESTAL
2
ON for pedestal (7.5 IRE offset selection for NTSC); OFF for no pedestal
4 4XOVRSMPL ON to enable oversampling
3
; OFF to disable oversampling
For 2 X OVRSMPL (see section
5.1.3)
5 NTSC
ON for NTSC 3.58 (see Table 4)
6 PAL
ON for PAL-B (see Table 4)
7 AUTO
ON for multi-standard; OFF for user-selected (fixed) standard (see Table 4)
8 BAR
ON for machine to operate as a 75% color bar generator (based on the clock of
the SDI input)

1 For example, passing data such as Teletext
2 NTSC offsets the black level within the active video signal by 7.5 IRE when selected
3 When a signal is digitally sampled at frequencies much higher than the NYQUIST frequency. When this method is used, the
noise figure is improved
