3 — SOG (sync on green)

On — The interface outputs sync on green.

Off — The interface outputs separate horizontal and vertical sync (on the H and V connectors) for RGBHV.

4 — V-Sync Width (vertical sync pulse width) — For some digital display devices, if no picture appears, the picture cuts in and out, or the picture is scrambled, try adjusting the output vertical sync pulse width or switching from ADSP to DDSP.

On — The vertical sync pulse is narrow. Off — The vertical sync pulse is wide.

5 — Neg Sync — This switch controls sync polarity.

On — Both the horizontal and the vertical sync signals are forced to negative polarity on output.

Off — Output sync polarity follows (is the same as) input polarity.

6— Comp Sync — This switch controls composite sync output.

On — The interface outputs combined horizontal and vertical sync for RGBS. Off — The interface outputs RGBHV or RGsB video.

Step 9 — RS-232 control

For two-way RS-232 communication, connect an RS-232 device (control system or PC) to the 3-pole captive screw connector. Software for RS-232 control is included with the interface. Refer to the “Remote Control” section of chapter 3 of the user’s manual for further details. Wire the male connector, as shown here.

Video signals passing through long cable runs of over 125 feet (38.1 meters) can decrease in strength, creating signal loss. The longer the cable, the greater the cable resistance and capacitance, and the greater the level and peaking adjustments that will be required to compensate for the resultant signal loss. These adjustments change the level and peaking of the output signal to compensate for capacitance caused by up to 1000 feet (304.8 meters) of Extron SHR cable.

NIf the displayed image is too bright or too dark, try changing the level setting. If the edges of the displayed image seem to exceed their boundaries, or if thin lines and sharp edges look thick and fuzzy, try changing the peaking setting. See the illustration below.
