AC2
6. CODE SUB-GROUP
Four buttons on eight rows of the RC68+, identified by athe numbers 0 through 7 (see Fig. 2), will
execute the same set of 4 commands listed above, when selected by the CODE SUB-GROUP switch
on the AC2. This is useful to prevent mutual interaction in common IR systems when using more than
one AC2.
To change the CODE SUB-GROUP, simply rotate the CODE SUB-GROUP switch on the AC2 to
the number that corresponds to the desired row on the RC68+.
Remove power from the AC2 for 20
to 30 seconds.
Re-apply power and use the chosen row to execute the commands for that particular AC2.
NOTE: No changes are needed on the RC68+!
7. Code Group Numbers. The AC2 is also capable of being set to different basic code groups as well
as the sub-groups.
NOTE:
When shipped from the factory, the AC2 is set to code group number 28. Be sure to
set the RC68+ to the same number!
It would only be necessary to change the AC2 to a different code group if the common IR bus system
included more than eight AC2's. The code group change would then prevent mutual interaction.
Refer to the RC68 instructions for code group setting procedures.
DELAY SWITCH
The AC2 allows you to delay the turn ON of the SWITCHED OUTLET over a range of 0.05 second to 60
seconds, by use of the DELAY switch (Fig. 3).
The Time Delay Chart, Fig. 4, lists the available DELAY times for each position of the DELAY SWITCH.
This allows you, for instance, (with the use of more than one AC2) to space apart the turn ON times of 2
or more high powered devices (such as large power amplifiers). This prevents high simultaneous inrush
currents from overloading AC power circuit breakers, etc.
NOTE: The DELAY is the time between the start of the CONTROL IN voltage (AC or DC) or VIDEO IN sync
and-
a) the ON state of the SWITCHED OUTLET.
b) the presence of +12 VDC at CONTROL OUT.
IMPORTANT: Delay action does not apply
a)
to the IR INPUT control signals.
b)
to the turn OFF condition.
