Switcher ActiveCNX Interface

Switcher TAKE: When high, triggers analog signals
i1
and
i2
to determine
the appropriate serial string to send to the switcher, in order to execute the
switch.

NOTE:
In certain cases the Scheduler may try to send many switches in
rapid succession to this ActiveCNX Interface. This might occur if there were
several rooms in a group and one source was selected—the switcher would
have to switch the input to each room—or if more than one room were set to
the safe channel simultaneously. It is suggested to write a SIMPL+ module
that queues the input/output pair each time a TAKE is encountered. Using a
loop in the Main() function, the strings that are sent to the switcher can be
slowed to a manageable pace. The program HeadEndMSX.smw contains a
SIMPL+ module that does this.
