3F. Master Keys: Part 3 - Direct IR, Sequence IR, and Managers
One of the key automation features of the IntelliControl is its ability to select Preamp and
Television “Inputs” and “Modes” three different ways:
Direct IR - A Different “Single” IR Code for each of the Component’s Inputs.
This is the most desirable type of preamp, television monitor, or projector to automate.
Access to inputs is quick and absolutely reliable. The end user may freely use the
component’s original remote control as well as the IntelliControl.
Testing Direct IR
Try each of the IR input commands twice. If any of the input commands act like a “toggle”
on the second push (and actually switch the television back to another input), “Direct IR”
input selection will not be reliable. If some of the IR input commands do not toggle,
consider routing the components to only those TV inputs that do not “toggle”, leave the
other inputs that do “toggle” unused.
Sequence IR— a Single “Input Toggle” Command and a Secret Back-Door
“Anchor” Command(s)
This is a very desirable type of preamp, television monitor, or projector to automate. The
“Anchor” IR command (or series of commands) takes the device to a known input, then a
sequence containing the required number of “Input Toggle” commands is issued to take
the device to the correct input for the source selected.
Access to inputs will be delayed up to 2.5 seconds for some sources (if 5 input changes
were programmed into a sequence). “Sequence IR” input selection is absolutely reliable.
The end user may freely use the component’s original remote control as well as the
IntelliControl.
Finding the Secret Back-Door “Anchor” Command
Most manufacturers do not acknowledge the existence of “Anchor” commands. Basically,
it is an IR command (or sequence of IR commands) that has some other normal purpose,
but the manufacturer has designed the device to go to a specific input (or execute a
specific function) when this command is given, regardless of what input the component is
currently in. These functions are typically reserved for use by factory service technicians or
engineers.
The most common television input “Anchor” commands are “Channel Up”; “Channel
Down”; “0,0,ENT”; “9,2,ENT”; “9,1,ENT”, but there are several others. When you test a
new television model, use your imagination when trying various code combinations, since
each manufacturer has their own ideas as to what is effective.
Testing the “Anchor” Command
Once you have found the anchor code(s), they must be tested. Make sure that no matter
what input the component is in, issuing the anchor code will select the specific anchored
