I also say. Use a FilterLinc on the UPS AC input. Most UPS devices have a power line conditioner in it and it absorbs Insteon and X10 power line signals. I have my UPS AC input on a FilterLinc with the PLM in the pass through outlet on the front.

There is a special SD card replacement procedure. As you have to put the firmware back on the new card. As the ISY994i has a minimum firmware in it until the firmware is put back on it. https://wiki.universal-devices.com/ISY-99i/ISY-26_INSTEON:Replacing/Formatting_an_SD_Card No backup at all? That may require you to have the programs, scenes and modules manually redone. I would also try the cleaning the contacts on the old one and seeing if you can access it in the iSY994i and if it worked. Do a backup and then replace the SD card as a precaution.

RF devices are in a power saving state and you have to wake them up individually to read and write data to them. When doing a restore. It is best to turn off automatic writes to wireless devices. If you have that option. ISY994i PRO and I believe all eisy's have that option. So you don't have all the retires and failed message to slow down the restore.

I know there was two major 2456S3 ApplianceLinc modules and more than one firmware revision. So it could be possible some did not work well with recent PLM revisions. It was only partially supported for I2CS according to the information we got in the Developers Forums. I personally had issues with later PLM versions and the 2440 original RemoteLinc. Had to have it on the other end of the house. So the PLM didn't use its RF receiver and had to us the power line from a different RF receiver back to the PLM.

The failed one is definitely with in the warranty and contacting them should get you a replacement. V2.7 is a very recent revision.

I also have X10 addresses in my Insteon Modules and an HR12A. I also do not like the Insteon remotes. The Range Extenders I have looked at are a 2457D2 Dual Band Lamplinc with the dimmer circuit removed. They even kept the same FCC Database number on them. Four tap test also works fine. Testing to other modules. Like me and others. I have a 2457D2 or other Dual Band module being used as a Range Extender. Since it is only being used for range extending. It is not even in the ISY994i setup.

The 2456S3 is power line only. The manuals description of how Insteon works does show Insteon can also be RF and maybe what is confusing you. As Dual Band does use both the AC power line and RF. If the module is Dual Band or RF only. It would have an FCC Database ID on its label and in the specification sheet in the manual. It will show the RF frequency and AC power requirements. Manuals are sometimes confusing from what I have seen and read. Some of the Developers notes they gave us had errors in them.

1) Did you cycle the power to the PLM and then let it reboot? During then test? In case it had locked up. We have seen a PLM get lost and needed a reboot. Though a PLM starting the fail also would sometimes work for a short time. Sounds like you are correct and the original has failed. If you had also rebooted the PLM and eisy during your initial tests. What is the revision number on both PLM's? That may give us some added information.

No the 2456S3 ApplianceLinc is not dual band. It is the original Insteon relay module and is power line only. Is in the larger case like a PLM and has a pass through outlet on the front. If it is a 2856S3 it would be a Icon version of the original AppliancLinc. The 2635-222 On Off Insteon Module is dual band. The model number is on the back of the module. full 2635-222 manual too big to post here but can be found in the support section of Insteon.com 2456s3_newer.pdf 2635-222qs-en.pdf

The Revision Number on the PLM. Should be an indicator of its firmware and hardware.

V1.7 is an older PLM and it is possible it is failing. With the capacitor issues we have seen. 1222 could be week 22 of 2012.

If the wall wart supply is old. Try a replacement. ISY994i has a wide input voltage range and we have seen wall warts cause all kinds of issues here. I personally had one on an ISY99i and one on a ISY994i go bad.

Can't comment on the color wires. Yes just 3 wires. If yours is working then you got it correct.

Yes both the IRLinc Transmitter or Receiver. Are both power line only. Faded memory here. I believe they where in the drop down list with other unique modules like the motion sensors.

Just try to duplicate how the old one is wound and taped.

I have some power strips that also have a AC rated Capacitor across the line and load. They work good to remove power line noise but also absorb Insteon and X10 power line commands. That extension cord. Looks like it has no signal conditioning at all. Turning off load sensing may show something. Capacity of the two conductors or noise absorbed by the coiled cord. Maybe but maybe hard to pin down.

Openadr was standard in every ISY994i Portal Integration and Networking where purchased added modules. You can no longer purchase them and if you want to transfer it from one to a different one. The end of service post. Seemed to indicate they would do it for $125. I only used the A10/X10 module as an example. I don't know how many here actually have it. Now over on the X10 forums. Where I am a Community Advisor, I have seen some using an ISY99i or ISY994i exclusively for X10.

Especially if the load sensing feature is on.

If the restore from a unit with the A10/X10 to one with out the A10/X10 module. It probably would go through but if the A10/X10 module's features where being used by the old ISY994i. It could cause issues. Though that module was cosmetic and allowed X10 and A10 module to be seen in the console tree. Data on the A10/X10 feature. Just the info. Being available now is over. Since the ISY994i is discontinued a few years ago. https://wiki.universal-devices.com/ISY-994i_Series_INSTEON:Enhanced_A10/X10 We have seen issues with a backup from a PRO on one with no PRO. If the scene and programming information was larger than the standard unit was using. I don't have any thoughts on the. Portal Integration module.

Did a test with my spare ISY994i. Using a backup from my main ISY994i. Spare does not have the Networking Module installed. PRO,A10/X10 are on both. Also no installed Insteon modules in the spare. The backup for the main unit did program the spare. Including the Insteon modules in the main unit. Insteon modules didn't respond to tests as the PLM on the spare has a different six digit ID. The Networking Module did not get installed from the main unit backup. Password from the main unit did transfer to the spare. As did the name of the ISY994i. As my main one was an early one called My Lighting and the spare ISY. I don't think an ISY994i that includes the PRO add on. Would be a problem. As it adds more space for programs and scenes. Control of automatic writes to changes to the system. Going the other way may make a difference if the original with PRO had more programs and scenes in it than one without the PRO.

Yes the Polisy section of the UDI Wiki shows it has serial port. Polisy supports the following PLMs: 2412S and 2413S through the DB9 connector on the back. 2413U and 2448A7 through the USB port on the back. If you have a 2413S (serial), you will need our Serial PLM Kit. My thought are if you want to use the 2413S on a USB port then the adapter is needed. Since that model is supported. Opening a ticket may get more results. https://www.universal-devices.com/contact-us/

The modules are tied to the ISY994i's UUID number. That is different for each ISY994i. If you buy a used one ask the seller exactly what it has in it. You may find a similar set of modules in the replacement. The backup has the scenes, programs and setting in it. I don't believe the backup has the firmware and installed modules. My backup files also have the title with the UUID in it and my second ISY994i has its UUID in the backup's title. I will try a test if I can. To see if a backup from one ISY994i worked on second ISY994i. If both have the same set of modules them.

5.3.4 is the last firmware version for the ISY994i. It is what I have in mine and a spare. Manually is the only way. With the firmware file. To see the whole thread. Including a link to the firmware Click on the up arrow in the post from Geddy

If you can get into the Help Info Tab on your present ISY994i. It will tell you what you now have. So you can see what the ones on the auction sites have. Like the Pro and other add on features are in them. Pro adds more link and scene space you can use in the ISY994i and also allows you to turn on and off automatic updates. Your present ISY994i may also have other ones like Networking. So features you now use will still work if you get a replacement ISY994i.

Long shot here. We have seen strange things happen when the wall wart supply starts to fail. You may want to just try one and see. ISY994i has a wide input voltage range. UDI last time I looked was selling a 12VDC 2A. My originals where 5VDC 500mA or 1A
