One for All EXTENDER A1 FOR URC-7780 Instructions Manual page 27

should consist of four FFs (even though the default label shows as HT in the Device Buttons pane). The
characters that can appear in a device label, with their hexadecimal ASCII codes, are:
A 41 F
B 42 G 47
C 43 H 48
D 44 I
E 45 J
where SP means the SPACE character. Note that SPACE can be used in a label, it is just that it should
not be the padding character, and that IR.exe considers the Full Stop (2E) to be illegal and changes it to a
SPACE. To correct a character, highlight the hex value in the Raw Data display and enter the correct
value. When you have made all the corrections, press the Apply button. Until you do so, you can undo
your amendments by pressing the Undo button, but once they are applied they cannot be undone.
Device Code Upgrades
Device code upgrades, and any associated protocol upgrades, will be carried across to the extender. No
action is necessary.
Volume Lock
Volume Lock settings can be viewed and changed in the Other Settings pane of the General tab of IR.exe,
where they are referred to as VPT (Volume Punch Through) settings. They are active in the unextended
device only when VPT Status is "On". The VPT Device (the device controlled by the Volume buttons
when Volume Lock is on) is displayed there and Volume Lock is applied only to those devices where
"Xth Dev uses VPT" is also "On".
All these settings will be carried across to the extender but it is only the settings of VPT Status and VPT
Device that it uses. When set On, by default Volume Lock is applied by the extender to all devices. The
extender uses a different method to exclude a device from Volume Lock. This is explained in section 5 of
this manual.
Learning
The learning facility is the one major feature sacrificed in the use of extenders – all extenders, not just this
one. The memory area for learning in the unextended remote is used in the extender for Key Moves and
Macros, since the memory area that these occupy in the unextended remote is used to hold the extender
code.
This lack of learning capability is rarely a serious drawback, however, since IR.exe enables you to
identify the hexadecimal code or EFC value corresponding to a learned signal, so that it can be set up
instead as a Key Move. If you need to learn a signal and discover the corresponding code after you have
installed the extender, you can always exit the extender to return to the unextended remote as explained in
section 11. This will restore the learning capability. When you have finished you need simply to re-
upload to the remote the ".ir" file of your extender setup and re-enter the extender.
It is not necessary to take any action to delete any learned signals currently set up in your remote.
Learning will be automatically disabled and the learned signals over-written, at least in part, by
installation of the extender upgrade. However, there may still be garbage left behind in the EEPROM
from learned signals that do not get over-written. A cleaner installation is therefore obtained by deleting
all learning with the menu item Advanced Setup/Function/Delete Function/Delete Learning/Delete
Learning From All Modes.
