Installation and Operation

Description

The RGB 116p has a Video Bandwidth of 150 MHz and is compatible with any Analog computer system with a horizontal frequency range of 15-100 kHz (optimum 15-62 kHz). Using Extron MBC Cables, the RGB 116p is compatible with VGA, Super VGA, IBM PS/2, MAC, MAC Quadra, XGA, XGA-2, DEC and many others. Call Extron or refer to Extron’S Handbook of Computer Interfacing for a complete listing.

2.Disconnect the local Monitor cable from the computer and connect it to the MBC cable.

3.Connect MBC display output cable to “Analog/ECL” on the RGB 116p.

4.Connect the MBC’s CPU cable to the computer’s video output.

5.Apply power to the RGB 116p, the CPU and

monitor.

Automatic Sync Output— The RGB 116 p will automatically strip incoming Sync from the R, G & B video channels. Sync will output one of three ways, depending on the output termination.

• 75 ohms on only R, G, & B channels, output is sync on Green.

• 75 ohms on only R, G, B, & H/HV channels, output is composite sync.

• 75 ohms on R, G, B, H/HV & V channels, output is separate H & V sync.

Installation and Operation

Operation

Power LED: Indicates if the RGB 116p is receiving power.

Horizontal Center Control: The H Center Control [ ] shifts the displayed image left or right.

Front Panel

Universal Input: Using EXTRON’S MBC input cables allows viewing on both the computer monitor and large-screen projector/monitor at the same time.

Termination Switch: 75 ohm video termination for applications with no local monitor (Sw7, below).

RGB 116p with Laptops

When using the RGB 116p with laptops (or computers without monitors) a termination adapter must be used to simulate a monitor. If not, the computer/laptop may not boot up or may default to an undesired lower resolution. Extron has termination adapters for VGA, MAC, SUN and SGI. 75 ohm video termination is selectable via DIP switch control.
