3.Connect MBC interface output cable to “Analog/ECL” on the RGB 120p.
4.Connect the MBC Power cable to the RGB 120p.
5.Connect the MBC’s CPU cable to the computer’s video output.
6. Apply power to the RGB 120p, the CPU and monitor.
Automatic Sync Output— See Sync Output illustration. The RGB 120p will automatically output Sync on the coax cables being used, if they are terminated with less than 1K ohm.
• Sync on
•Composite
(not V).
• Separate H&V
Sync is automatically stripped from the Red,
Green and Blue channels.

V CENTER | PEAK |
Level Control: Increases (clockwise) the output video level from .3 to 1 volt
Peaking Switch: Selects from three levels of peaking to compensate for mid and high frequency signal losses due to cable length. This is similar to the sharpness control on a monitor. The 3 switch positions are 0 (for no peaking), 50% peaking and 100% peaking. Select the peaking level for the sharpest image on the display. Note:
Universal Input: Using EXTRON’S MBC input cables and buffers, allows viewing on both the computer monitor and
MBC Power Source: Use only to power EXTRON’S MBC buffers.
Termination Switch: 75 ohm video termination for applications with no local monitor (Sw7, below).
