EFC stands for Extended Function Code.
UEI remotes do a very good job of generic coverage
of most brand name equipment. However if you need functionality
that is not included in the generic setup, UEI has provided a way
to supplement these codes using EFC’s. EFC’s can be
entered through the remotes numeric keypad, and they can be pasted
(or keymoved) to remote buttons for regular use. A keymove is easy
to setup with our software and cables, but it can also be via a
keymove 994 command. See this Manual
Programming How To Quick Reference to see how to setup keymoves
without the benefit of a cable.
In order to utilize EFC’s without an upgrade,
the remote needs to be a UEI remote capable of doing keymoves and
the remote must have a setup code that properly formats a signal
according to the specific protocol rules. If you have a cable or
a modem upgradable remote, you can simply add the upgrade with the
JP1 tools.
Most UEI remotes can do keymoves. The newer flash
remotes use 5 digit EFC’s, which provide more functionality.
Older JP1 remotes, can only use 3 digit EFC’s, near the end
of the JP1 era, 5 digit EFC’s were used. During the transition,
a few remotes that we know of were not able to send EFC’s
at all. If you have an older remote, you will not be able to use
the 5 digit EFC directly, but using the JP1 tools you may be able
to find a simpler protocol which may send the same signal using
3 digit EFC's. If your remote uses 5 digit codes, you must prepend
any 3 digit EFC's with 00.
Depending on the remote, the setup key may be
labeld SET; SETUP; P; or MAGIC. You can send the EFC immediately
by using a short press of the setup key, followed by the EFC. Of
course that isn't very convenient for commonly used functions. So
the normal thing to do is to keymove the EFC to a key for ease of
use. The keymove remembers the setup code that was in use when it
was created. So if you change setup codes, the keymoves will still
reference the setup code that was in use when the 994 command was
performed. This can be very useful if you need to combine different
types of signals, but you also need to remember to delete those
keymoves if you switch out your equipment. Keymoves can be assigned
to most buttons on the remote. Most remotes also support keymoves
on shifted keys. A shifted key can be be accessed with a short press
of setup key prior to pressing the key. If however you desire to
assign the shifted key to a numeric key (0-9) you must press the
setup key twice before pressing the number key, otherwise the remote
thinks you are trying to send an EFC.
With newbies, there seems to be a lot of confusion between setup
codes and EFC’s, especially on the remotes that use 5 digit
EFC’s and 5 digit Setup codes.
A setup code is a reference to the remotes internal library of
codes. A booklet or pamphlet came with your remote listing the available
setup codes in the remotes library. The EFC’s on the other
hand are codes that translate to one function within the setup code
such as the number 1 or the volume up.
