I have an early revision 1.0 2445 and gave it a look. You are correct it uses 3.3 volt logic. I found the three controller chip programming connectors. All three of them have the +3.3 Volt and ground pads on them. Not the +5 volts and ground I have seen in the PLM. It also has the same switching power supply as the 2413S/U PLM. So I suspect at sometime they will need replacement. I did a test with a serial port board from a 2413S V1.0, installed in a V2.5 Access Point. It did not act like a PLM. It just did the proper functions as an Access Point. It did not even connect with my PLM test programs. I think you are confusing the physical hardware looks with the modules normal functions. As far as I can tell a V2 Access Point hardware has no PLM functions built into it and different firmware than a 2413S PLM.

No a 2414U USB daughter board will not work. The USB interface chip is hard coded the the 2414U speed of 4800 baud rate. The PLM is 19,200 baud rate. I did put a 2414U daughter board in a PLM main unit and had to change my test speed from 19,200 baud to 4800 baud to even access it. The 2414U daughter board does have some link database memory on it but it will be at a incorrect baud rate needed to talk to a ISY controller. You also do not have any Link Data base memory on the main 2413X board. It is on the serial or USB daughter board and required for proper PLM operation. The Administrative Console has a few tests to read and compare the data in that memory and it is used for properly addressing the units being controller. All the signals you should need are on the 8 pin male headed on the lower edge of the 2413X main board. +12 volts unregulated changed to +5 volts on the daughter boards regulator, common for all the signals and voltages, 5 volt level send signal, 5 volt level received data signal, SD for the date used by the on board database memory and SC clock signal for the on board database. The PLM uses 5 volt logic signals. Can't say about the HUB as I have not looked yet. But I expect to see some 5 volt regulator on it. Though some recent electronics have gone to 3.3 volt logic. I do admire your trying to fix this terrible problem. Please keep us informed on anything you find out. I sure wish the member used a HUB and RS232 interface had provided more data on connection points and board used. To see if it had other features besides the basic RS232 to TTL function.

Yes that is true. I am well aware of what it does. I have a box full of unused ones in storage. But any version 2 Access Point is on a 2413 main board and suffers from the same power supply issues as our 2413S. I kind of doubt it uses a PLM signaling protocol between the main control chip and the RF control chip. It uses TTL logic signals (0V and +5V) and has a 5 volt logic power supply not a 3.3 volt one you have found. Though their still be a +5 volt logic supply you have not seen yet. The Link Memory in the PLM is on the serial or USB daughter board. If their is no daughter board their is no Link memory. The HUB should have its link memory on the main board. If the TTL to RS232 board you are using in your link. The part number shows it can use 3.3 Volts as a supply. TTL to me is 0 or +5 Volt signal swing. Got any schematics links you mentioned. It could be clearer to me with that information.

Can't find anything on a 2143. The 2443 is the HUB with Home Kit Enabled features. Smartlabs called it a HUB PRO. I can't say about a HUB since both my 2242-222 older HUB and 2245-222 newer HUB, are sitting unused in a storage box. I have seen a photo of the older HUB where the separate Ethernet board was removed and a serial board connected to the main board. The 2245-222 and probably the 2243-222 newer HUB have everything on one board, My FCC photos show many rows of possible connections in the 2245-222 HUB. You may find more voltage and signals available. Do you have a part number on the converters chip? That would give a clue to what voltage it needed. I did see a note on the Ebay page on a used chip. I will see if I can find more details on that chip and hopefully have better information. Said as low as 3.3 Volts.

Has anyone posted results for the also rare 2413U USB version working?

The 2412 main boards only have three capacitors. 1000uF/25V, 470uF/50V and 100uF/16V. Are power line only. Large fairly heavy power transformer. May have the always on outlet on the front cover. The 2413 main boards use the ones in their kits. Since Smartenit makes their own daughter board. Any cap for the serial port daughter board probably would not be used. There where two serial port boards but the cap differences between them should not effect their daughter boards.

You may want to peek inside one of them and see if the capacitors are the same? Smartenit used the newer Dual Band 2413 mother board in some of them and the kit should be the same caps. The early ones and latest ones went back to the older single band power line only 2412 mother board. The later ones because they also had power supply issues like our PLM has. The caps in a 2412 board are different sizes completely.

That link is the PLM Pro by the now gone Smartlabs. It had a universal power supply 100VAC to 240VAC. 50, 60 cycles. Back plate was separate so it could be changed to match the local electric outlets. Faster memory and link database increased from ~1000 links to ~4000 links. Looked similar to the case size used on the 2457D2 LampLinc. Serial, USB and Ethernet versions where in the FCC data.

It only has three wires in it. RS232 Receive, RS232 Send and a signal common wire. The remaining connections on the PLM serial connector. Are TTL send, TTL receive and if the older 2412S unregulated +12 volts. Should not normally be connected to anything.

I too would suspect the power supply. There are many posts here with failing power supply. I have had a few myself. UDI presently sells a 12 Volt supply as the ISY994i has a fairly wide power specification.

I found my rough sketch of a 2430 supply area. The C2 470uF/35V is the 30 volt main supply and the 30V Zener diode is across the cap. The black mark on the bottom is probably that diode getting warm. I have seen this before. It is used for the power line transmitters power. The C4 100uF/16V is in the +5 volt logic supply used by the electronics.

I don't know how well its features are supported but this is what I have found. In the device choice tab in 5.0.16A. There is a module they called a Smoke Sensor. Category 10, Subcategory 0A. In the 2982.222 manual it shows a Category of 0X10, Subcategory 0X0A. Good chance they are both the same module.

My bad. I would suspect the larger one as it is in the main supply. Though would not hurt do do both as a safe thing to do.

I remember your post and fix. For the 2430 ControLinc Maxi. I would at least look at the board and see if it has a similar problem. Maybe try a new capacitor. My thoughts where with the cap not working correctly. There was too much ripple current in the diodes. The black rectangular diode next to the large capacitor is a zener diode seen in many of the older Insteon devices.

On mine I had to get far enough away from the Dual Band PLM to do anything with it. Like put it into the linking mode near a Dual Band device on the other end of the house away from the PLM. So all the signaling had to go through that device and the PLM did not receive it by RF and used the power lines.

Not sure if things have changed now. When it happened to me years ago. Federal, State and Local owed taxes and fee where top of the list. Then secured loans. End users where at the bottom of the list.

I don't use any that dim. I use all relay type Insteon modules as I am from a past where LED bulbs did not dim. Though the old one I still use have local control sensing and some pulse at a few second rate.

I have seen bulb manufacturers change a hardware design and not change the description. That can effect how a dimming style LED bulb works.

The 2450 is power line only. So it has to be with in RF communications range of USB Dongle. To a dual band module that can communicate on the power line to the 2450. The 2450 also had a switching power supply chip in it and depending on its age. May have a failing supply or is the original I1 signaling standard. That used a large amount of peeks and pokes to do one link. If you have an extra dual band plug in module. You can try and plug it into the outlet on the front of the 2450 and see if anything changes to link it.

Yes the site is up The Fanlink along with everything I looked at is marked "Sold Out". Though you has the access the modules sale pages before you got the "Sold Out" message

The UDI Wiki has lots of tips, videos and how to pages. The ISY Cookbook available there is also a great help. Along with the users here. https://wiki.universal-devices.com/index.php?title=Main_Page

I have not seen a post officially killing the 2413S PLM has been out of stock for at least 6 to 9 months. I suspect it is gone unless there is an event in the future.

You may want to look at their web page drivers tab. I don't have a Polisy so I can't say if any of them are compatible. https://www.aten.com/us/en/products/usb-peripherals/usb-converters/uc232a/?source=google

Even at fast On and Off with a full On setting, on a dimmer is not a god way to go. There is still a possibility it may not play well with an inductive load. Unless it has an OK for a dimmer ratting. There is also a short time at Zero Crossing where the output is distorted. When turning on between the cycles. Switching from positive and negative.

If you don't have a PLM. You can still do z-wave with added card. There are ISY994i models that are z-wave only and could use the software that didn't flag a no PLM found.
