Features
The SC 210 is a 250 MHz sync processing device. Any type of
RGB signal can be converted to any other type. This is determined
by cable connections and DIP switch settings. For example:
Input
Output
RGsB
RGBS, RGsB, or RGBHV
RGBS
RGsB, RGBS, or RGBHV
RGBHV
RGsB, RGBHV, or RGBS
RsGsBs
RGsB, RGBS or RGBHV
The SC 210 can also be used as a sync stabilizer to eliminate jitter.
The SC 210 automatically strips incoming sync from the red, green
& blue video channels.
Operation
Power LED: Indicates if the SC 210 is receiving power.
Automatic Sync Output Detection
Sync can be output in three ways, depending
on the impedance detected through the
output cables:
Impedance = 75 ohms on R, G, and B,
or up to 1 kohms on Sync lines.
• Impedance on only R, G & B channels,
output = Sync On Green.
• Impedance on only R, G, B, & H/HV channels,
output = Composite Sync.
• Impedance on R, G, B, H/HV & V channels
output = Separate H & V Sync.
DIP Switch Settings
As stated above, the SC 210 outputs sync
according to the impedance detected on the
output cables. However, the DIP switch
settings take priority. If a switch is set, it forces
a condition, regardless of what is detected.
The DIP switch settings are shown below. In
the default positions (all switches OFF), sync output is determined
by the impedance detected through the output cables.
