Write Recall E-MEM Register (DB) Command
Write Recall E-MEM Register (DB) Command
Recall E-MEM is a write-only command. When sent, the command causes the
state data in the speciÞed E-MEM (Effects Memory) register to be recalled, thus
changing the current state of the switcher to the stored settings for the given
effects addresses. This command performs the same action as manually recalling
an E-MEM register number of 0 through 99.
Control bits may be set to force or inhibit the recall of the register as an effects
dissolve. Additionally, control bits may be used to force or inhibit the running of
an effect which contains multiple keyframes, and the recall of learned enables
prior to the recall of the register.
NOTE: Do not send this command more than once per video frame. Also note that
a new recall command received by the switcher will override any recall that is still
in progress for an effects address.

(1) Not supported in Version 5.0 and earlier
Effects Addresses
Prior to Version 5.1, when an individual Effects Address was speciÞed, the
switcher disabled all but the selected E-MEM level on the panel. With Version 5.1
and later, that no longer happens. Instead, the panel is left in its current state.
