Upgrading An Existing Installation - One for All EXTENDER A1 FOR URC-7780 Instructions Manual

To perform this merge, open the File menu of IR.exe and select Merge Using ExtInstall. If a prompt
appears saying that the data has changed and asking if you want to save it, say yes and save this pre-
merge version where you wish. A window will then open headed "Select a .HEX File". Navigate to the
folder that contains the files you extracted from the extender package, select
URC-7781 Almost Clean A1.hex
or URC-7780 Almost Clean A1.hex
as appropriate and then press the Open button. A new window will open, headed "Save". Navigate to the
folder in which you want to save your personalised .ir file, and enter your choice of name in the "File
Name" box. Press the Save button. The merge will take place, the merged file will be saved with the
location and name that you chose and you will be left in IR.exe with this file open.
You continue by following the instructions for a "Clean installation" given in section 2.3, but using your
personalised .ir file instead of the supplied one. You already have this file loaded into IR.exe, so you pick
up the instructions of section 2.3 with the second sentence of its second paragraph, "Upload this to your
remote." The only difference is that when you come to add devices as described in the third paragraph,
you have available your retained setup codes in addition to the built-in ones. If you have recorded the list
of your original device labels and want to re-create them, this third paragraph is the point at which you do
so. The TV device is already present. Add the remaining devices in the order they appear on your list,
accepting for now the default labels. Then use Change Device Label to make any changes to the labels
that you desire. You should not need to use Move Device, as the LCD display will show the devices in
the order in which you added them. Continue to the end of the "Clean installation" instructions. You
have then completed the basic installation of the extender for your devices and should continue reading at
section 3.

2.5 Upgrading an existing installation

Do not be fooled by the fact that these instructions are much shorter than those for a Clean or Almost
Clean installation. They are shorter because those instructions spelled out in detail the preparation
required. They ensured that no garbage was left over in the EEPROM data from your original installation
and they removed any data errors that may have been present as a result of incompatibilities between
IR.exe (version 7.15 or earlier) and the operating system of the URC-7780 and URC-7781 remotes.
When you upgrade an existing installation, it is up to you what preparation to make. Appendix 2 of these
instructions provides the information you will need, but it does not and cannot tell you what to do. It all
depends on what your current setup data contains, what of it you wish to retain, and what data corruption
may have been caused by previous use of IR.exe due to the incompatibilities just mentioned.
So here are the instructions. First read Appendix 2 and make any preparations to your existing setup that
you decide are necessary. Open IR.exe, connect your remote and download its setup to IR.exe.
The next step merges this setup with the extender data, resulting in a ".ir" file for the extended remote that
includes whatever setup data you preserved during your preparation. Open the File menu of IR.exe and
select Merge Using ExtInstall. A window will open headed "Select a .HEX File". Navigate to the folder
that contains the files you extracted from the extender package, select
URC-7781 Extender A1.hex
or URC-7780 Extender A1.hex
as appropriate and then press the Open button. A new window will open, headed "Save". Navigate to the
folder in which you want to save the .ir file, and enter your choice of name in the "File Name" box. Press
the Save button. The merge will take place, the merged file will be saved with the location and name that
you chose and you will be left in IR.exe with this file open.
Upload this to your remote. You will receive a warning that the signature of the upload differs from that
of the remote, asking if you want to proceed. Say yes. The remote will then take you through its usual
