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

The cable between the ISY994i and the RJ45 style serial port on the PLM. Is a standard network cable. So trying new one should not be too hard. Mine came with a 3' Cat5E. I am using a 6' Cat 5E from my ISY994i and the PLM. The SID message could mean the SD card in the ISY994i is corrupt or failing. There are some reports of that also.

After I create a scene. I can then control that scene in a program. Where it can be set to do things like turn on or off at preset time, dusk or dawn with even a choice like dusk +- a preset offset, days to run it. In your three way example. The scene will create the needed links and levels. So your using the switches paddles will control each other. Putting the scene in a program is not needed for it to work. Only if you wanted the scene to also be activated at a time or maybe a signal from a motion sensor.

If the original switch is not Insteon and has more than one built in function. The wall mounted wireless control would not work. With out changing the presently used switch. To an Insteon one and it would have to have the needed functions to control the fan and lights if they can be controlled separately. If the optional wall mount for the remote has not changed lately. Mine is designed to mount on to the wall and not on an electrical box where the remote seems to just fall into the box.

If they are dimmers. You can also set the On level and ramp rate of each switch when in that scene. I have my morning On scene also sounding an Insteon 2868-222 Siren Module for 6 seconds using the Siren tone not the Beep or Chime tone. Default is 30 seconds. I could also have that module in a different scene using a different set of settings. Set in the particular scene not the modules list which also has a setting choices.

I too would suspect the shorted triac if everything else still looks OK. I could not read the part number on it. In the FCC Database internal photos. It is mounted on one of the sides of the heat sink. With what looks like a rivet. It also shows a switching supply IC (LNK354GN) for running its electronics power source.

If you are using an ISY994i. The manual linking information was to be ignored. I don't have a HUB but I believe it is also recommended to ignore the manual linking information also. Modules and the controller both need links to each other to function. Some times one controller could possibly overwrite unknown links. Some modules no longer support X10 officially but may still accept an X10 address. I have mostly older modules and have both ISY99i control and my HR12A Palm Pad controls them also. Though the ISY994i doesn't see the changes. I have the optional A10/X10, Network and PRO firmware firmware add on's. Latest 5.3.4 firmware available for an ISY994i. At one time until dissolved Insteon Developers Group and the developers notes all ended up as released to the public.

If you linked the two switches with the Set Button and then added them to the ISY994i. You may have issues. As the ISY994i should always do all the linking. So it has the correct link information in it. Other wise it may cause broken and half links but I believe it maybe possible. I never tried and always used my ISY994i to do everything. Links done by your 2412N may also not be properly in your ISY994i/2413S PLM setup. The UDI WIKI has much good information in in. The ISY Cookbook is a big help along with the other helpful information and experienced users here. https://wiki.universal-devices.com/index.php?title=Main_Page

Two more papers that may help. I also started in X10. One point that sometimes makes a difference. Some X10 repeaters. See the end part of an Insteon message as an X10 message. Falsely sending a X10 message back on the power lines. insteoncomparedV2.pdf insteondetailsV2.pdf

The choice was by the former owners Smartlabs/Smarthome. Some of the other pins on the RJ45 type connector. Are TTL in and Out. Older 2412S also has a unregulated +12VDC (19VDC)thankfully not in the 2413S PLM.

This may give you some information on Insteon. http://cache.insteon.com/developer/developer-guide-022009-en.pdf There are many archived Insteon information here. https://github.com/pyinsteon/pyinsteon/commit/2533494a8b13b30b2d0938c9a18afe782b740410 Just be aware that the 2412N has a history of failing.

Correct on the USB to serial cable. The PLM serial USB to RJ45 connector side uses three connections (Send, Received and Common) not in the normally used pin out. The UDI one is special in its connections.

The I/OLinc has a switching power supply in it. Along with the capacitor issues. They did replace the main cap with a larger capacity one with a higher voltage rating. My old V1.0 the supply voltage dropped every time the relay was turned on.

If you have all the features you want or need and a new supply puts you back in business then an upgraded ISY device is not need. Though new features are nice. I don't need and use any of the new features. So my ISY994i will be all I need and use. Besides I even have a backup ISY994i.

Power supply was one of the frequently reported issues with an ISY994i and older ISY99i. My original was a 5V 500mA and it failed similar to what you where seeing. After an AC outage and restore. The LED's sarted to flash as it tried to boot and then reset due to low voltage.

ISY994i has a wide DC input range. Many here use 12V 1 or 2 amp. Been awhile but last time I looked. UDI was selling 12V 2A units for the ISY994i https://forum.universal-devices.com/topic/31558-isy-994-power-supply-question-regarding-voltage/

Plug in On and Off module? Not one of the new dual function I3 switches that can be a dimmer or a switch? The dual function module look like it has a triac so it can dim maybe in on off it is locked on or off. Unless they have a triac and a relay (doubt it).

If you did not use the replace with function. All the modules being controlled may still have the old KPL ID in them and will not respond to the replacement. With out some manual intervention.

Not 100% on this as I don't use any of them. That looks like a fuse resister and the module has issues as you found out.

You are welcome. Hope it helps and I am glad the FCC Database had the internal photos.

I have seen a post on the former owners forum. Of someone doing that. I believe it was finding a battery close enough in size and some reported the case snaps where glued in later revisions. My statement was not completely correct on not realizing the battery had built in protection. From the FCC Database web site. Battery.pdf23422ip.pdf
