If it is a standard DB9S connection on the USB to Serial port. It use 2, 3 and 5 on the DB9S side.. The ISY994i uses RJ45 pins 1, 7 and 8. With the signals reversed on 1 and 8 from the 2413S PLM side. So the proper signal is directed to the correct signal pins on the other device. As pointed out by mwester. It is not a simple set of connections and adapters. You do need some intelligence to process the USB signals. The FTDI chip in the 2413U normally needed a driver in the computer to get it a serial port assignment.

The serial cable between the RS232 adapter and the ISY994i does not look like the correct pins are being used. I will have to see what I can determine. I know the 2413S uses Pin 1,7 and 8. To the ISY994i. So it should also use 1,7 and 8 for its connection to the PLMs serial signals. RJ45-1 is the serial out to the ISY994i. RJ45-8 is the serial in from the ISY994i. RJ45-7 is the signal common for both devices. The included cable if used used the standard DB9P pins 2, 3 and 5 to RJ45. The information in the 2413S quick guide. May give you some added information. I will ring out the serial cable included with the 2413S. Remembering the cable was to interface with the PC serial input port. http://cache.insteon.com/documentation/2413Sqs-en.pdf

Depending on which pins where connected. There is unregulated +12 volts (about 18.5 volts) on pin 1. It maybe possible it got into some other signal pin. That would depend on which way it was shifted. I have done a similar thing myself. Though in my error. One or more of the male pins on the main board got bent and ended up on the outside of the shell on the serial card.

I also agree. The pin out digaram on the Amazon site. Shows all the signals on the incorrect pins the 2413S and ISY994i used. You will have to get the correct signals from your converter. To the proper signal connections on the ISY994i. To simulate it talking to a 2413S PLM. Only TxD RS232, Out, RxD RS232 In and SG signal ground are used. RTS,CTS,DSR, DTR, and RI are not used and best not to be connected to the ISY994i Converting the 'B' style to the 'A' style adapter. May also be a problem. The USB connector on the 2413U PLM. Does not have the +5 volt out connection on it. On a 'B' type connection it is a +5V input supplied from the device it is connected too. So you will have no power to the USB to Serial adapter.

Both rows connected but one pin off right or left? Whole row connected to the other row and the other row not connected to anything?

The 2413U USB PLM. Has a FTDI USB interface chip in it. It uses a FTDI VCP driver to make it look like a serial port to the computer. There is no +5V on the 2413U USB connector. It is a B type meant to be tied to an A type on the computer. That has a +5VDC on its pins. The USB (monitor) jack on the ISY994i is described as "The Monitor port (ISY-994i Series ONLY) is a micro USB port used for initial configuration for users without a DCHP-enabled network, or for advanced troubleshooting. Please use a standard micro USB cable to connect your ISY to an available USB port on your PC." The unit wants to see a PLM on the A Serial port RJ45 type connector.

Maybe the serial card was effected. At V2.3 they updated the serial interface chip. To one with a higher ESD protection spec. At V2.4 the serial board was redesigned with the new chip and a protective network was added to the serial I/O lines. I had seen a post that indicated some 2413S units serial ports had issues. Besides the power supply problem many of us have seen. Maybe it was effected by the power issue. You did verify the 8 pin connector between the two board are all in place?

Only the older 2412S provides power over ( unregulated 12V normally about 20V) its serial port RJ45 type connector. In the 2413S they did not put F1 on the serial daughter board. So no voltage was on the serial connector. Starting with V2.4 the serial board is a new design and there is no power to the serial connector. A ISY994i could be powered by a 2412S. It did have the pins wired. It also had a diode in the voltage input. As did the power connector on it. If booth where connected only one provided power.

Thanks for the information. I have the Pi Zero not the Pi Zero W. Though it maybe the same for the USB ports on mine.

My Pi Zero. Has a separate USB connector a power supply plugs into. That has a matching plug on it. The other USB connector is for communication with it.

Let us know if it works with an ISY994i controller. I know the ISY994i checks for a connected PLM at startup. I don't think it uses the subcategory ID. So the serial connected 2413U reporting USB. Should not effect things.

It has been suggested. I don't know if anyone has tried it and reported back with results. I did a quick test with a 2412U USB PLM and daughter board from a 2413S. The 2413 serial board has a faster link memory speed. So putting it in a 2412 should not effect it. It did work in my brief tests with some PLM test software. I did not try it in any further tests. The USB PLM with a serial port daughter board. Will report it is a USB model not a serial model. As they have a different subcategory ID when they are interrogated by software or connected controller. May or may not effect its use. Depends on what is connected to it and if it check for serial or USB.

2842-222 is the original Motion Sensor. Category 10, Subcategory 01 2844-222 is the Motion Sensor II. Category 10, Subcategory 16. You did link them with the Sensors List in the Link Menu and pick Motion Sensor II? If you added them in another way or picked Motion Sensor and not Motion Sensor II in the list. That may give some clues. If it was added as an original Motion Sensor. The features you wanted are probably not available.

The capacitors especially C7 and C13. Have been changed by Smarthome many times. In an attempt to try and fix the power supply issues. They finally went to a 100uF/50V and rated for a switching power supply at V2.3, some earlier revisions had 100uF 35V or 50V. Your C7 and C13 100uF/35V caps where in some of the revisions. One of my original V1.0 has a 10uF/25V and rework to add the coil and both capacitors hanging off the PC Board with a fly wire to back of the PCB. Another common C7 and C13 where 10uF/35V. The C7 and C13 100uF/50V where too big to fit the board space and hole pattern. In those right from the factory. Are laying bent flat on the board with their leads bent to fit into the original board solder pads. There maybe a photo buried in the thread showing them. You will probably have to lay them on the board and connect them to the solder pads. Being careful the leads don't short to things.

If you don't have a PRO. Adding that feature would increase the number of links. I believe it also increases the nodes. If you have the PRO already. Then you have hit the limit. You could ask UDI in a support question. If they don't find it here. https://www.universal-devices.com/contact-us/

I did a few double checks and I don't think there are any errors. C7 and C13. 100uF/50V or 10uF/50V. Earlier ones where 10uF. Smarthome changed to 100uF. May have to lay 100uF on it size. Most are using 100uF/50V for the 10uF/50V. https://www.mouser.com/ProductDetail/EPCOS-TDK/B41858C6107M000?qs=ziqVJVjjmkzaaRB22pWdiA%3D%3D. https://www.mouser.com/ProductDetail/Panasonic/EEU-FR1H100?qs=tfZGHB2PWd1NAbdNSgjToQ%3D%3D C3 10uF/400V https://www.mouser.com/ProductDetail/647-UPW2G100MHD1TO?r=647-UPW2G100MHD1TO C8 10uF/16V https://www.mouser.com/ProductDetail/Nichicon/USV1C100MFD?qs=6UFrbFY2dcTclg9NCH6OBw%3D%3D C11 100uF/25V https://www.mouser.com/ProductDetail/Nichicon/UTT1E101MPD?qs=isV%2BNJxyrb747oJy1YayIg%3D%3D

Well many of the stock numbers on Mouser have a Zero in stock tag. With some expected next year and others are no date known. This blog on a 2413U repair. Same main board in both. Seems to be a good read. https://1projectaweek.com/blog/2017/6/2/repairing-a-failed-insteon-powerlinc-power-line-modem-plm-2413u All of the capacitors it called out are still in Mouser stock (yesterday) except the 100uF/50V. One is a general purpose but in a circuit that should be OK with it. I may try the part numbers I used to see if they have any stock and find a 100uF/50V as I used the older 10uF/50V for C7 and C13.

https://www.universal-devices.com/docs/production/ISY User Guide 4.2.8.pdf https://wiki.universal-devices.com/index.php?title=Main_Page The connection from the ISY994i serial connector to a 2413S PLM is a CAT5e network style cable. Your ISY994i kit should have had the main unit, a power supply, 2 CAT5e Network cables and a Quick Users Guide. Not a normally seen DB9 serial cable. The pin out diagram and signals are shown in the 2413S PLM quick users guide. Only the RS232 Out, RS232 In and Common Ground are used. The TTL level signals are not used in this setup. https://cache-m2.smarthome.com/manuals/2413Sqs.pdf The 2413S PLM did come with a Network RJ45 connector to DB9 connector cable buried in the box. With only three signals RS232 Out,RS232 In and Common Ground carried through. In this case it is not used.

In the blog post linked to. A reply said theirs was different and only had a 1000uF/25V, 470uF/50V. There is also a 100uF/6.3V. If they looked at the part number of the module. That is the older 2412U power line only model. Many of us started off with the 2412S. Before the 2413S was produced. If you have an original 2413S Hardware V1.0. The board will not look the same as in the photos and the power supply will have rework on it to add to the power supplies connections. A coil and both C7 and C13 are hanging above the board and a wire will be running to the solder side of the module. You may also see C7 and C13 in yours laying on their side. With the leads connecting to the board. The 100uF/50V caps used by Smarthome. Where physically too large to fit directly into the connection pads.

The ISY994i ZW+/IR Pro. Communicates with the PLM by a serial communications signals protocol. You need a 2413S Serial Port PLM not a 2413U USB PLM. If you where strictly ZWave then the PLM would not be needed. As it is only needed for Insteon and X10.

I will see what I can find out.

The main board is the same in both the Serial and USB versions. The difference is probably what it reports when asked its ID. With a different Sub Category Number and a USB or Serial Port Daughter Board. Five electrolytic capacitors. The ones that fail. Since the power supply is a switching type and the capacitors where questionable. Starting with V2.3. C7 and C13 where changed to a version rated for switchers and maybe longer lasting. The daughter board in the serial version has one electrolytic on its 5 volt regulator for its logic power, 100uF 16V. Also four 1uF 25V for the serial interface chips internal power supply. They could be changed but I don't think they are a high failure part. Most of the users don't change them. I also saw a post awhile back on the serial interface chip failing. In V2.4 the daughter board was redone and they added some protective components on the serial signals from the outside world along with a chip with better ESD protection ratings. I don't have much information on the USB version. So it may have two electrolytic capacitors on its daughter board. That board was also in the 2443 Access Points Hardware V2.0 and above. I had a pair have the same power supply failures as my 2413S PLM.

If the 2443 is a hardware V2.0 or higher. It is built on the same 2413 base PLM assembly and has the same power supply issues the 2413S PLM we use. I also had strange issues until I rebuilt mine. That failed. The older V1.? one are on a different main assembly and do not have the same power supply issue.

Did the distributor indicate the ISY was discontinued or they have decided to no longer sell it? The 2413S PLM maybe a harder thing to find. Not sure when the Smarthome PLM Pro in the FCC Database will be available or if it is going to replace the 2413S. Due to the world wide electronic parts shortages. Unless you are doing Z-Wave and don't need a PLM.

The 2413U USB model. Uses the exact same commands, link database, power line and RF receivers and transmitters. As the 2413S PLM does. It is accessed by a USB cable for its connection to the outside world. The 2413S PLM uses serial communications. It should act like a Dual Band module. Like any other Dual Band module when connected to the AC. I have an older 2413S in a plug just sending and receiving power line and RF Insteon signals it sees. When the PLM starts having a power supply issue. Sometimes its link database looses links. So commands and modules may not be processed. In the Insteon forums. I did see some information on the serial interface chip having problems. In that case the ISY994i may have problems talking to the PLM. Long thread 25 pages when I looked. If you are technical enough to rebuild it. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/
