Appendix 2: Preparing To Upgrade An Existing Installation - One for All EXTENDER A1 FOR URC-7780 Instructions Manual

Appendix 2: Preparing to Upgrade an Existing Installation

A setup of the unextended remote contains some or all of the following elements:
Devices
•
Home Theatre
•
Device Labels
•
Device Code Upgrades
•
Volume Lock
•
Learning
•
Key Moves ("Key Magic")
•
Timed and Key Macros
•
This Appendix provides the information needed for you to decide what changes, if any, you need to make
to each of these setup elements before you install the extender as an upgrade in accordance with section
2.5. In your decisions, please be aware of a feature of IR.exe that can cause unexpected problems. If
IR.exe finds data in a setup that it believes to be in error, it will "correct" this data without notifying you.
So when there are incompatibilities between a remote and IR.exe, as there are between the URC-7780 and
URC-7781 and the current version 7.15 and earlier of IR.exe, this hidden "correction" can actually be a
corruption that will become incorporated into your remote when you upload the setup. So merely
downloading a setup to IR.exe and then uploading it back to your remote has the potential to corrupt your
setup, even if you believe you have made no changes.
The preparations described in the Appendix should remove any corruption caused in this way. To the
best of my knowledge a remote with this extender and the accompanying RDF file is completely
compatible with IR.exe 7.15, so no further corruption should occur once you have installed the extender.
Devices and Home Theatre
If you delete all the devices, this will automatically delete all the other setup elements except Device
Code Upgrades. This corresponds to making an "Almost Clean" installation, so you should follow the
instructions for this in section 2.4, rather than continuing with those of section 2.5. This Appendix will
therefore assume that you wish to retain at least some of your current devices.
Start up IR.exe, connect your remote and download your current setup. Look at the Device Buttons pane
of the General tab. This shows how your current devices, identified by their type and code, are assigned
to device buttons Dev1 to Dev13. A type HT and code 2047 means that device button is not assigned. A
type HT and code 1011 means that device button is assigned to Home Theatre. The device button
numbers are irrelevant to the normal usage of the unextended remote, but they play a central role in
setting up the extender.
When a device is added to the remote, it will be assigned to the first available device button. It will
remain assigned to that button until it is deleted. The order in which devices appear on the LCD display
is determined by the settings 1st Dev, 2nd Dev, etc. shown in the Other Settings pane. It is these values
that are changed by the Move Device item of the remote's setup menus.
The Clean and Almost Clean installation methods ensure that devices are added in the order in which you
want them to be displayed, so that 1st Dev is Dev1, 2nd Dev is Dev2 etc. This is a convenience, but it is
not essential. These methods also ensure that Dev1 is the TV device. This is highly desirable but not
absolutely essential. If Dev1 is anything other than TV, it is the Dev1 device rather than TV that must be
selected in order to enter the extender, and you will need to press the Record key twice, not once.
