The serial port daughter board. Has a RS232 interface chip. MAX232 in <V2.3 and a MAX232EI (better ESD specification) in >V2.3. 2.4 Also added a input protection network on the two serial signals. It also has two TTL level signals on it. Though it is not protected at all. The signals tie to the TTL signals on the serial port chip and no buffer or protection at all from the outside world.

In the FCC Database. Smartlabs has a replacement for the 2413S PLM. 2234-223 serial version 2234-222 USB Much better specifications. Like universal power supply, larger link database, faster clock, better RF and power line signal processing . Serial and USB versions where shown. Now will it ever see the light of day. That is another unknown.

The 2474D has to get its power through the load and should NOT be wired to control an outlet. As a dimmer is not allowed to control an outlet where someone could plug in an incorrect load. Like a fan. It only has a Black Line and Red Load wire. If you capped off the Red wire. It would have no way to get power. Is the other switch an Insteon dimmer with the three wires? Black Line, White neutral and Red Load by chance?

The 2474 two wire switch. Steals it power through the load and designed for incandescent loads only. Other dimmable loads may or may not play nice with the switch. It is also Insteon RF only as it has no power line sending and receiving. It only has two power wires and ground. Line and Load no Neutral connection. Not 100% on this but do remember seeing it also can not work in a three way setup.

There are more than one way to wire a three way switch in a home. Depending on where the load and line are connected. Along with the traveler wires between the two switch locations. So tracing the connections is sometimes needed. Good you where able to wire it from the diagram in the manual. Not all setups could be wired like in the manual.

Was the LampLinc the older 2456D power line only one by chance?

Do you have any controls now? Like their manual wall switch or optional RF control kit?

You may want to try the Dual Band module. Plugged into the I/OLincs front pass through outlet. Yes you should be able to use the Manual Linking feature in the modules. Using the modules set buttons. To link the I/OLincs Sensor Input to the 2466S. Looking at the modules full users manuals will give you the information. You may have to pay attention to the 2466S state when linked. As you can actually link a module into a manual scene. Where an On would have the module linked to be Off.

I saw that posted in the local news. It is enabled by default and you have to opt out.

If the LED on the PLM is not On. That is one sign of a 2413S PLM failures. As its power supply has failed to the point nothing is working. If you are in a Safe Mode. That would also indicate the PLM has failed. In the Safe Mode. Some features are not available. I don't think you lost all of the programs. You will have to run the PLM replacement procedure to write the new PLM Insteon ID Number into all of the Insteon modules in use. Power down the ISY994i and old PLM. Connect the replacement PLM to the ISY994i. Power up the PLM and ISY994i so it is found during power up. Use the Restore Modem (PLM) function to write the new PLM ID into the modules. If you have a PRO model you can turn off automatic writes to battery powered devices. So you can restore each one individually as battery powered module have to be its programming mode first.

If you want to do what cpamario did and have no pump controller. Wanting it controlled by Insteon. You would not need a pump controller. You would need one of the Smartenit modules and a six conductor wire from the Smartenit module to the variable speed pump. I found a installation guide. If the pump has a waterproof connector on the side of the pump. The cable mentioned in the Smarthome post would be a good idea. There is more information in his Smarthome Forum post. https://forum.smarthome.com/topic.asp?TOPIC_ID=20867 MrBill's interface also sounds interesting.

Thank you for the clarification on the Diode V reading. I got out my DMM users manual and looked at the display. For the Diode test. Sure enough the displayed number is the forward voltage drop on the diode being tested. Thanks again on the proper information.

In may ~60 years of being an Electronic Technician. I have never seen a diode tested using the V reference. I used my meters ohms or Diode Test setting. So I have seen a new way to list a diodes test information. That was why I asked if you where powering things as voltage to me means powered up. If you are getting close to the same in both directions. Does sound like they are shot. Garbage or electronic recycle sound like a good way to go.

If you have a Diode test in your meter. The diodes should have a conductance in one direction and a high reading in the other direction. So the 30V diode should read like any other diode. If you don't have a Diode setting. Depending on the ohmmeters voltage on the probes. You should get a fairly low resistance in one direction and a much higher resistance in the other direction. I don't understand your using a V reference. As resistance is in ohms. Unless you are reading the voltage across a diode while powered up. I called out the capacitor by its value. Would have been clearer if I had said 470Uf/35V

You may want to look in the UDI Wiki for some information. It has all kinds on information in it. https://wiki.universal-devices.com/index.php?title=Main_Page The Safe Mode indicates. You have no PLM (2412S or 2413S) found when the ISY99i is powering up. It could be possible you cant register the unit. As it was discontinued years ago. If you do get it going. 3.3.10 is the last firmware released for it. So the recently released Insteon Modules would not be supported. Like a Siren Module as an example. Found this in the UDI Wiki. https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Quick_Start_Guide

You may want to open the Event Viewer in Level 3. Then you can see the messages being sent and received back from the module. You should be able to save the messages in a text form. To look at it or post it here. You may want to check you Firmware version and UI Version are the same. Help about. Latest ISY99i is 3.3.10. The 2475S is single band and the 2475SDB is Dual Band as you thought. Do you have any other Dual Band Modules, Access Points or the Range Extenders in your setup?

When you changed the PLM. Did you power down the ISY994i and old PLM. Change the PLM. Power up the PLM and ISY994i? Then use the Restore Modem (PLM) function. To go out and change the old PLMs six digit Insteon ID to the new PLMs ID? If you have a PRO version. You can turn off automatic updates to battery powered modules and then restore each on separately.

I would also say. Watch the PLM carefully. The 2413S PLM has a reputation of failing. After two years and a few months. If you have any 2443 Hardware revision 2.0 and above Access Points. They are also on the base 2413 PLM main board and can also fail. I had two myself. Some of the symptoms is Link Database is 0 or almost empty, works for a short time after a power cycle, Status LED is dimmer than you normally see. There is a real long thread here on how we rebuilt ours along with symptoms reported. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

When they changed to the 2 LED cover. I did see a Smarthome note to dealers. That you could buy older ones as a color change kit part. To match the older ones you may have in the home now. Now all the accessory plates and light pipes seem to be gone.

The condensate pump has a safety switch which can be wired in either NC or NO mode. Does it have anything connected to it now? As the I/OLinc's Sensor Input is made to use a dry contact connection with no voltage on it. As it supplies its own low current signal. I have seen reports of some variable speed controls. Generating power line noise. So you would have to see if it effects the I/OLinc and 2466S are effected by it running. Both are power line only Insteon modules.

Have you tried opening a trouble ticket with UDI. They have a good support system in place. You may want to mention this thread to them.

The power LED in mine is driven directly from the ISY units power supply and a current limiting resistor. There have been a few others posting here that their power LED was off. With no other symptoms being seen. You may want to see if anything in the troubleshooting section of the UDI wiki. I thought I saw a section on the log entries and will see if I can find them. The UDI Cookbook also in the wiki may have something in it. https://wiki.universal-devices.com/index.php?title=Main_Page#INSTEON_2 https://wiki.universal-devices.com/index.php?title=Main_Page

I have seen no posts indicating the new PLM requires 5.3.x. I have no information on what V2.6 has over the older ones. It could be possible it has revised transmitter and receiver circuits. Are your modules Dual Band or the earlier power line only ones? Coupling between the incoming power lines? If you have the 2443 Access Points for coupling and they are any V2.0 or above. They are built on the same base 2413 main board and suffer the same power line issues we see in the earlier versions of the 2313S PLM. I had a pair mess my system up until I rebuilt them. The V1.X 2443 where on a different chassis and where much better. You may want to run the built in communications tests in the Access Points, Range Extenders or Dual Band modules. To see what the tests may show. Anything new in the home or an existing device moved to a new location? Around the time the communications started to go down hill? Some electronics generate power line noise or are signal suckers. I bought a few of those new deformable garage lights. One model has a .2uF capacitor across the power input and it severely absorbs power line signals. The other model I was trying generates so much RF garbage it can kill things like a garage door openers Rf controller key fob.

The PLM has a reputation of failing. In tools, diagnostics, PLM Info/Status does it show connected and the PLM six digit ID Number? Does it get better for a short time if you power cycle the PLM and ISY994i? Is the LED on the side of the PLM On at about the normal brightness? When you tried the new PLM. You would have to do a restore PLM after a power cycle of the ISY994i and PLM or all the Insteon modules would have the old PLM 6 digit ID in them and not respond to the new PLM 6 digit ID. The system would be busy rewriting the new PLM 6 digit ID into every module. This is for Insteon. Z-Wave doesn't use the PLM 6 digit ID. The power supply also has been reported to fail. 5VDC to 30VDC. 1 amp probably best. The UDI store had a 12VDC 1 amp last time I looked. Do you have Z-Wave as the files you pointed out. Seem to be Z-Wave files but probably checked even if Z-Wave is not installed. If the power supply was flaky. It may have corrupted the SD Card. With file errors now happening. Event Viewer in Level 3 may show some of the communications failures and successes. The Log and Error Logs may also show some information.

If the fuse has continuity. Then it should be OK. D3 is the 30 volt Zener diode. One side would be on the 470uF + and the other side on the 470uF -. The + side of the 470uf would also have continuity to the AC Line pin. In your second photo. From the top edge. On the right side of the 470uF cap. MOV1,D1 (black body), D3 (glass body), D9 (glass body).
