Front Panel Operation

Auto Power – Senses computer power and automatically turns the RGB 202xi power ON.

Level Boost – Similar to a contrast control, this control raises and lowers the output signal level from the original input level. e.g. a VGA input of 0.7v peak-to-peak (p-p) can be adjusted for an output level of 0.3 to 0.8v p-p (without boost). Within the boost (red) range, the output can be raised to 1.25v p-p.

Peak Control – Similar to a sharpness control, this control compensates for mid and high frequency bandwidth response in data monitors and projectors, and for signal losses due to cable capacitance. A sharper image will be seen from most computers, regardless of cable length. For long cables, the setting will probably be above the 50% level. Use your visual judgement when using this adjustment.

Blue Enhance – Used with TTL signals (Input #1), allows the mixing of blue with green for displaying text that is easier to read (blue-green color).

V Centering (vertical shift) – Moves image up or down on the display screen. (Not active if DIP switch #1 is On) Memory stores settings to keep image centered when switching inputs.

H Centering (horizontal shift) – Moves image left or right on the display screen. (Not active if DIP switch #1 is On.) Memory stores settings to keep image centered when switching inputs.

LCD Screen – Alternately displays the horizontal and vertical frequencies of the selected input.

H LED (red) – Lights when the LCD is displaying the horizontal frequency of the selected input.

V LED (green) – Lights when the LCD is displaying the vertical frequency of the selected input.

Input Switch – Used to select Input #1 or #2 (both video & audio) for output from the RGB 202xi. (If in the #1 position, a constant contact switch may be connected through the rear panel for remote switching.)

Introduction • Features and Specifications

LCD Sync Processing – Exclusive to Extron, our LCD sync

processing makes the RGB 202xi work with CRT and LCD based presentation displays.

Input Switch – The RGB 202xi interface can be connected to the outputs of two computers at the same time, making it a two-input switcher as well as an interface. The Input switch is used to select which input source (#1 or #2) will be displayed on the connected monitor or projector. Both inputs are universal.

Termination Switches – These switches allow for 75 ohm termination of the connected computer for either of the two inputs. With this feature, an external termination adapter is not required when using an Analog type computer without an external local monitor (i.e., a Laptop).

Automatic Sync Stripping – Sync is automatically stripped off any incoming signal with sync on the red, green and blue video channels. If desired, it can be added back to the green output signal by the use of a dip switch, or Auto Sync output detection.

Auto-Sync Output Detection – Automatically senses the impedance on each BNC output, determines which ones are being used and sends the proper sync output.

Audio Interface – The RGB 202xi includes a PC/computer audio (600 ohm) to line-level audio (balanced) converter. For computers that have a sound card, the audio interface will select that audio input together with the video (audio follow). The audio output can be connected to an external stereo system.

Two-Input Switching – The RGB 202xi may be used as a two input (one Analog/ECL and one Analog/TTL) switcher. Input selecting can be done by the front panel toggle switch or with an optional external switch plugged into the rear panel remote connector. Audio input is switched with video.

Local Monitor Compatibility – Using an MBC (Monitor Breakout Cable) with the RGB 202xi allows for computer monitor and large screen display image to operate at the same time. This allows the presenter, or computer operator to use the computer's (local) monitor while the audience watches on the large screen.
