They control the load output from the module. The pair can be controlled for the load connected to it and it can be used to control other devices.

Did you have a chance to look at the revision of the 2443 Access Points? Any revision of 2.0 and above are base 2413 PLM electronics and can have the same capacitor issues. One of mine the LED on the side was off and the second one was very dim. In my case the same capacitor fix for the 2413S PLM worked. You can try power cycling them and see what happens. You can also do the 4 tap communications test on them. 4tp test also will run on the 2413S.

You may also want to run the built in tests between the two 2443 access points to see if they are still communicating. If they are any revision 2 units. They are built on the base 2413 PLM and have the same capacitor issues as the 2413S PLM. I had to rebuild mine with capacitor issues.

The internal and external photos. Look like the AC input could be changed to match the countries standards. Of course this was back in the days when they actually had modules in other countries but the PLM was 120VAC 60Cy only.

This is from the FCC Database files for the 2234-232 updated PLM replacement. Sounds like the present owners maybe thinking about producing it. Expanded operation to 100-240VAC and 50/60Hz. Increased Insteon links storage from ~1000 to ~4,000 links with faster read/writes Uses the same communication protocol and structure to match earlier models Updated all processors with increased memory space and speed Beefed up electronics to reduce failures due to AC-mains electrical spikes, noise and heat from poorly ventilated install locations New and smaller enclosure that matches other Insteon plug-in products Increased power line transmitting signaling levels and robustness New RF circuit with higher sensitivity components and calibrated antenna circuit Supplies 5VDC capable of powering single-board computers like ISY TM controllers Added fast TVS surge suppression on the Serial port to prevent static damage For the Polisy and eisy users. There was a 2234-222 USB model.

The DST issues where also reported on the Insteon Forums. So the ISY products where not the only controller with possible issues.

My older ISY994i changed as expected today.

Also they are RF devices and go in to power saving mode. Each one has to be woken up individually and then do a restore on it.

Module has to be restored as there are writes pending to the module. If battery operated module has to woken up first. Also effected by turning on and off automatic writes or battery devices.

If some of your modules are the older power line only models. They can be effected by power line devices as the new devices in the house are added. So in theory older modules may not fair better. Even with the great UDI products.

You may have to have the special UDI USB adapter on the Polisy end. As I am not too sure if it can do serial. I know the eisy can not do serial. There are other signals on the RJ45 style connector that you do not want to connect to anything. Like TTL signals.

The 2413S has a special pin out on network style connector. Only three wires are used. Common, Send and Receive are connected. The signals are true RS232 with a Serial Port interface chip. At the least you would have to create a special cable.

I had some Revision 1.3 2456S3 ApplinceLinc modules fail. 120VAC coil relay in all. Started pulsing On and Off at about a 30 cycle rate. I replaced the main filter cap and they again where OK. Had a few with the snubber across the relay contacts go bad and try and keep the load on when the relay was off. Smoke and all. The 30 Volt Zener diode in the supply was famous for shorting or getting too hot and melting the solder or burning the PCB kind of black.

Good find. Thank you for the information. I too was part of the bad tact switch era but didn't have the date code units. In the recall by the Joe Dada era Smarthome. I do remember someone doing a tact switch repair fix it video. Mine would click just fine but nothing changed. As the switch did not make electrical contact. I vaguely remember an Icon version also had switch issues.

Are you using the USB to Serial adapter cable? The eisy does not work with a 2413S serial PLM. Unless the adapter is used on a USB port on the eisy.

Some manuals also had a flow chart of set button actions and led flashing patterns. To find the beacon test but I found on some. The good old four tap test also worked OK. Only LED flashing that was different. Was the older access points with the single color white LED. In that case it was the LED flashing patterns.

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.

The Microwave probably has some capacitors across the absorbing internal noise. They also absorb X10 and Insteon power line signals. It is possible over the three years. Something has changed. Here is the XPF instructions. from the X10 sales site. Note it is fairly large as it is 120VAC 20 Amps. https://cdn.shopify.com/s/files/1/0324/7511/9675/files/xpf-is_03804f43-a696-42cf-992d-7797f3dc34ba.pdf?v=1673368020

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.

I would also be careful with a microwave and a FilterLinc. It has a fuse in it. So if I works for a while and then goes dead. The fuse has failed. They are soldered in but can be replaced.

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.
