default setup code. The fourth press completes the addition of the TV device with this default setup code.
If you had Home Theatre set up, that will have been deleted automatically when the last "ordinary" device
was deleted.
Let the LCD display time out (go blank) and make another long keypress of the Magic key to re-enter
device setup. This time press LCDRight, Enter and LCDLeft to select the menu item Advanced
Setup/Reset. With Reset displayed, press Enter once so that User Reset is displayed, and then Enter a
second time to perform a User Reset. The LED should flash twice, then twice more, and the LCD display
should return to Reset.
Next, start up IR.exe, connect your remote and download the setup as it currently is. You should see on
the General tab that you have exactly one device set up, Dev1 with type TV. Go to the Devices tab and
select, in turn, each device setup code that needs to be deleted. Note that neither of the steps you have
taken so far remove or modify in any way any device setup codes you have installed as upgrades. As
mentioned above, the device setup codes you need to delete are any installed from Remote Master that
include Key Moves, as the Key Moves have already been deleted by the User Reset so that these codes
will need to be re-installed later on. If you are making a re-installation of the extender on top of an
existing extender, you also need to delete the device setup codes that correspond to the extender and its
special protocols. With the present extender, and probably most others, these are:
TV/1800, VCR/1800, TV/1101, TV/1103, TV/1104 and TV/1106.
For each device code that needs to be deleted, make a note of the Protocol ID shown in the Device
Information pane of the IR.exe display. Similarly select in turn each device that you do not want to
delete. Look at its Protocol ID. If that ID is one that you have noted down, cross it off your note. Then
go to the Protocols tab and see which of those remaining on your note are listed in the left-hand pane, in
the form Protocol: $xxxx, where xxxx is the Protocol ID you have noted down, padded on the left with
zeroes to give four characters. Those remaining on your note and which are listed must be deleted. This
will certainly include the protocols for the devices just mentioned that correspond to any existing extender
and its special protocols. To delete a protocol, simply select it in the left-hand pane of the Protocols tab
and press the Delete button at the bottom of the display (not the other one marked Delete that is in the
Data Addresses pane). You will be asked, for each one, "Are you sure you want to delete this upgrade
protocol?" Answer Yes to each. Repeat this process on the Devices tab to delete each of the devices that
need deletion. Again there is a corresponding confirmation question.
When you have deleted all the protocols and devices that need deletion, select the Advanced menu from
the top line of the IR.exe display and click on Clean Upper Memory. This removes any garbage left over
by the device and protocol deletion. When IR.exe "deletes" a device or protocol it actually only deletes
its reference from a lookup directory, in the same way that "deleting" a file on a PC actually only deletes
its directory entry, not the file data itself. The Clean Upper Memory process removes any device and
protocol data that is no longer referenced by the relevant lookup directory.
If you have followed this carefully, IR.exe now contains a setup for an unextended remote (even if you
are re-installing over an existing extender) that contains one device (TV), any device setup codes (with
corresponding protocols if required) that you installed through internet or phone downloads and any
installed from Remote Master that do not have associated Key Moves. Nothing else is present, except
possibly for a little remaining garbage in the area that manages device labels. Even this garbage will be
removed in the next step, which is to merge this setup with the extender. This merge process will create a
".ir" file that is your own version of the file
URC-7781 Extender A1.ir
or URC-7780 Extender A1.ir
supplied in the extender package, personalised by the inclusion of the device setup code upgrades that you
have retained and completely free of any garbage left over from your original setup.
