Operation

Video Gate Buttons

The Video Gate buttons turn individual color out- puts on and off. They also control the adsdition of primary color information to the NTSC / PAL video outputs on the 801GX.

The R push-button turns all of the red video outputs on and off.

The G push-button normally turns all of the green video outputs on and off. When a 2-bit digital monochrome (MDA) signal is being generated, the G push-button turns the I (in- tensity) signal of the video pair on and off.

The B push-button normally turns all of the blue video outputs on and off. When a 1 or 2- bit digital monochrome signal is being gener- ated, the B push-button turns the V (video) signal on and off.

The master output gating button overrides the settings of these buttons when turned off.

Many of the built-in analog video signal formats are stored with the RGB video signal type selected. If you are testing a monochrome monitor with the same timing, you can toggle between color and mono- chrome modes by pressing both R and B push-but- tons simultaneously.

An “m” appearing to the left of the image loca- tion on the LCD window indicates that mono- chrome analog video has been selected.
