5、Operation

5.1 Switching

Switching can be controlled by PVW, PGM, CUT, AUTO, PAT Keys and T-Bar. PAT:

Pattern select for current layer in PVW

PVW KEY 1-4: Source select for current layer in PVW

PGM KEY 1\~4: Source select for directly switch in PGM. When there are two layers in PGM, the selected source will display as Layer B

CUT: Switch PVW and PGM directly and immediately AUTO

:Switch PVW and PGM automatically with preset effect T-Bar

:Switch PVW and PGM manually with preset effect

5.2 Layer control

Both PGM and PVW support up to two layers, Layer A and Layer B. Each layer can be separately configured, including source, size, position, mask and keying.

A KEY/B KEY: Layer A/B control

If A/B KEY isn't active, Layer A/B doesn't display in PVW and A/B KEY is pressed, the A/B KEY will be active and Layer A/B will display in PVW.

If A/B KEY isn't active, Layer A/B already displays in PVW and A/B KEY is pressed, the A/B KEY will be active and Layer A/B will display on the top layer in PVW.

If A/B KEY is active, and A/B KEY is pressed, the A/B KEY will be inactive and Layer A/B will be removed in PVW.

Note: PVW needs at least one layer. Therefore, if Layer A is inactive, B key will active and Layer B will display in PVW, and vice versa. If there is only one layer in PVW, the corresponding Key will be active and it will keep active even being pressed.
