The XVSG command determines which video out- puts will be active when the format is selected. The same command controls both the analog and digital video outputs.

The value of XVSG can be temporarily changed by the operator, using the “R,” “G” and “B” video gating buttons.

The SSST parameter determines which sync type will be active when the format is selected. A setting of 0 will leave all the sync outputs off.

You have control over whether or not the op- erator can override the programmed SSST se- lection . A non - zero entry for the ASCT parameter will allow the operator to enable analog composite sync by pressing the “ACS” sync gating button. A non-zero entry for the DSCT parameter will allow the operator to turn on digital composite sync by pressing the “DCS” sync gating button. A non-zero entry for the DSST parameter will allow the operator to turn on digital separate sync by pressing the “DHS & DVS” sync gating button.

The SSST parameter does not override any indi- vidual programmed sync settings. For example, setting ASCT to zero and then selecting analog composite sync with the SSST parameter will leave all of the sync outputs turned off.

The HSPG and VSPG parameters determine if both horizontal and vertical sync are turned on when separate horizontal and vertical is selected.

Gating either individual sync output off with a setting of zero will keep it turned off even when the “DHS & DVS” button is pressed by the op- erator.
