Using the Learn Command in the Mode Menu new IR Commands can be learned.
To learn commands a remote control is entered at first. This is the name of the
ASCII File used by the database to store the commands of this remote. If the
remote control already exists the new commands will be appended.
First the Name for a new Remote control is
chosen and entered.Of course it is also possible
to enter the name of an existing Remote. Then
the newly learned commands are added to the
existing ones.
After the remote has been defined, a timing has to be learned. This timing will be
the basis for the commands. To learn the timing the remote has to be kept in a
straight line with the receiver. The distance does not matter to much but the IR ray
should reach the receiver in a direct line and not reflected by walls.
The advantage of the separate learning of the timing is, that the commands can
be learned very easily afterwards because the exact timing does not matter. In
general it is best to press the key of the remote only once and for a short period of
time. If you hold the key depressed for a longer time the recognition of the codes
may be compromised by special repeat codes the remote control uses.
Now a Timing can be learned. During that
procedure the IRTrans measures the Pulse
lengths of the IR Codes and analyzes the
Protocol. This is done by shortly pressing one of
the Remote controls buttons.
When learning a timing the Remote control
should face the IRTrans directly, not reflected by
wall as that might affect the timings learned.

After the timing is learned, the IR commands can be learned. Every command
gets an alphanumeric name that is used to identify the command later on. The
normal learn mode is based on the timing learned before. If you relearn a
command already in the database, the old command will be replaced by the new
one.
Next the IR Commands are learned. To do that
a command name is entered and the learning is
started by pressing Learn Command. Now the
corresponding Remote Button is pressed.
To learn a command the Button of the Remote
Control should be pressed very short.
This procedure is repeated for every Remote
Button. The VB Client always counts the
Commands and Timings and shows the Code of
the learned Commands.
For special purposes there are additional Learn modes:
!
Repeat Code.
This mode learns Repeat Codes. These codes are
sent if a key is held depressed. Not all remote systems use repeat
codes. You only need to learn them if keeping a button depressed
does not work. You only need to learn these codes for keys like “Vol-
Up” or other keys you like to hold down. To learn these codes you
need to keep the corresponding button of the remote control pressed
a little bit longer (like 1s).
