Video input connections
1 Input 1 (computer video) input (top) connector — Connect computer or RGB
video to this female 15HD connector.
2 Input 1 (computer video) loop-through (bottom)
connector —
Connect a local monitor to this female 15HD
connector. The scaler buffers the computer video input
and loops it on this connector.
The Digital Display Scaler buffers the computer video input signal before
passing it to the loop-through connector. Beyond that, it does not alter the
loop-through video in any way. The loop through output is the same
resolution and frequency as the computer video input.
3 Input 2 (RGB or component video) connectors — Connect RGBHV, RGBS,
RGsB, or component video (R-Y, Y, B-Y for YUVi or YUVp, or Betacam) to
these female BNC connectors (figure 2-3).
Ensure that the correct Input 2 video format is selected from the front panel
menu, see Input #2 submenu, in chapter 3, Operation, or via the RS-232
port, see chapter 4, Programmer’s Guide, and chapter 5, Scaler Software.

Figure 2-3 — Input 2 connections for RGBHV, RGBS, RGsB and
component video
For RGBHV video — Connect to five BNC connectors.
For RGBS video — Connect to four BNC connectors.
For RGsB and component video — Connect to three BNC connectors.
Video output connections
The two video output connectors, the 15HD connector and the five BNC
connectors, both output the same video signal. The 15HD connector outputs
RGBHV only, not RGBS.
4 RGB/HD R-Y, B-Y, Y Output 15HD connector — Connect an RGB video or
HD component video display to this female 15HD connector.
