If the PLM is on the same circuit as an UPS for the computing equipment. They can frequently absorb both X10 and Insteon power line signals. I have my UPS on the filtered bottom outlet of a FilterLinc and the PLM in the unfiltered pass through outlet on the front.

Any new or moved electronic devices. Around the time things changed? From your second test run. It sounds like you have a signal sucker or power line noise maker or a phase coupling issue. If you have an electric stove or electric dryer. They use 220 VAC and it you turn one On and the X10 gets better to areas with issues. You may have a phase coupling issue. If you have an X10 phase coupler in the system now. It may have failed. I have not seen any PLM X10 issues reported lately. I do have a 2456S3 ApplianceLinc that got X10 signal deaf but Insteon still works. Saw your mention of the firmware maybe not supporting X10 correctly. In another post. I was using X10 with v4.7.3 and v4.8.0 is supposed to have only disabled the Climate Module that was discontinued.

Do the Orbit sprinklers have low voltage AC controls? From what I can gather. The EZFlora has small triac's to control the valves and they need an AC voltage source. A model number of the Orbit you want to control. Would help in finding a solution.

Even at 100% on level. There is a short distortion of the AC power around the Zero Crossing. That may or may not effect the bulb or the bulbs electronics will not play nice with the dimmers. I would do a test of the exact bulb model if I wanted to try it and observe for unexpected results. If I wanted to try the mixture.

The EZIO2x4's GND is the reference for its 5 volt power supply. It is an isolated ground for internal use. It does not connect to the ground on the power line input or any other ground. When you are using the switched output on the device you are using. You have to have its common connection for the output switch and the GND of the EZIO2x4 tied together so the switch can be read.

You need two wires from the device to the EZIO2x4. If you are using the I2 inputs. +5 to I2+. I2- to the white wire on the device. EZIO2x4 GND terminal to the control circuits Black Common.

If you want to totally isolate the input. As the EZIO2x4 can accept up to a 30 Volt DC input. I2(I1)+ to the +24VDC. I2(I1)- to the third wire that connects to the 24 volt common when On.

Is the switch dry contact? Where both terminals are not referenced directly to the 24 volt supply? If the control signal switches to the 24 volt common or is +24 volts in one position and 0 volts in the other position. We may have to think on this a little more. Let us know if the third wire connects to the common 24 volt supply when activated. If the switch is a Dry Contact type. I2(I1)+ to EZIO2x4 5volts. I2(I1)- to one of the switches terminals. The other switches terminal to the EZIO2x4 GND Ground terminal should work. If the switch connects to the 24 volt common when On. I2(I1)+ to EZIO2x4 5 volts. I2(I1)- to the switches third wire for the switch. GND terminal on the EZIO2x4 to the 24 volt common should work.

No they are not added to the ISY setup. All you do is plug them in. Use the built in 4 tap/communications tests. To verify at least one other Access Point or Dual Band Module can communicate with it and on the same or opposite phase of the power into the home. Revision 1 white LED and Revision 2 Green/Red LED. The receiving Access Point's flash patterns are different. If they are any revision 2 Access Points. They are built on the same base board as the 2413 PLM. With the same power supply issues. I had both of mine get flaky until rebuilt.

Was much heavier and it may have a pass through outlet on the front cover? Sounds like the original EZIO2x4 was built on the Dual Band 2413 base board and the new one is on the older power line only 2412 base board. The 2412 base board used a real power transformer and was heavier. Not a switching supply like the 2413 base board. Like many here. They had issues with the power supplies on the 2413 base board and bought 2412 base boards from Smarthome. The original Smartenit (Simplehomenet) modules started out on 2412 base board then for awhile they used 2413 base boards.

The manual says it has Local Control. Normally if the module is Off. Toggling the loads built in switch from On to Off and back On. The module will turn back On with out you needing an Insteon command to turn it On. Some LED light bulbs and other loads can falsely trigger some Local Controls. Did you get random changes with a standard light bulb. Any noise makers on the same circuit?

OK. Glad you got a working spare. If the 10uF/400VDC was backwards. That would cause it to fail. Most likely it shorted and the 27 Ohm resistor did its job. Maybe preventing one of the diodes from failing with too high a current through them. If you used the 100uF 50VDC caps for C7 and C13. It is probably now close to a V2.3 component wise.

C1 on the schematic is not an electrolytic and should not have a polarity. It may have a stripe on one end. Indicating the outer foil lead. Do you know its value and voltage? Should be marked on the capacitors body. All the Electrolytic capacitors including C3 are polarized and yes it matters if they are in backwards. They will fail. Shorting is one thing and sometimes you get a rubber seal on the bottom or top bulging and blowing off steam and aluminum foil. Not familiar with your meter. On mine a diode reads 750 Ohms in one direction and several thousand ohms in reverse on the Diode setting on the meter. So 0 and .5 may or may not be correct. From the schematic and a back side photo of the main board. The 27 Ohm resistor connects to D3 side. The side with the stripe. Can you get a resistance reading on the C3 terminals?

Maybe a little more information may help. For the diodes. Set the test meter to Diode Test. Connect the test leads across a diode. Then reverse the leads. In one direction you should get a high reading in the other a low reading. The L2 coil. In Ohmmeter setting on the meter. A few Ohms. Depending on its characteristics. I have not measured one in a 2413 base board. For C3. I would connect a wire across it on the chance it is holding a charge. To discharge it. You could use a resistor as long as you are not touching both leads. This should also apply with the other electrolytic capacitors like C7 and C13 the two in the unregulated 12 volt supply. Closer to 20VDC if measured. Then the Ohmmeter probes on its connections. May start with a low resistance reading then rise to a higher level. Reverse the probe connections and again it may start low or even high go low and then back high. Make a note of the resistance after charging in both directions.

If it was a low current circuit. It maybe possible C3 charging and the electronics starting may have opened it up. The 27 Ohm resistor is supposed to limit the input current. Could be a brief current surge of a few amps. From the schematic may not match the silk screened markings. I would check the 4 diodes D1,D2,D3,D4. L2 and C3 with a meter .C3 may show a low resistance until it charges and read differently depending on which probe of the meter was on the + terminal. You may want to try both directions to see the differences. If the resistance is low and does not go higher as it charges. It is possible the U1 LNK345GN has a Source to Drain short or leakage.

I am glad you are up and running again. Will be watching for your findings on the old one.

Thanks for the information. I thought we where using the Serial PLM and an ISY994i. The V2.5 has power supply updates like the larger capacity and different series caps. Should be more reliable. Can't say about the USB Daughter Board as except for one old 2412U. All the PLMs I have information and dissections are for Serial Port PLMs. No experience with Indigo so this may not be pertinent. The new PLM has a new six digit Insteon ID. The modules being controlled may have the original PLM ID in their link database. So you may have to update their link databases.

Another option. Would get the original magnetic switch in the early Garage Door Kits. So you didn't have to use the Trigger Reverse function. I had both a NO and NC connection you could choose from.

A 2413U will not work with an ISY994i. Is this PLM for a different project not using an ISY994i? How did you get a USB model to work with an ISY994i? C7 and C13 are the higher size capacitors and the TY series designed for switching power supplies.

OK. Let us know how it goes.

If you are using a 2413U and different software. Not an ISY994i connected to it. Then the 2413U maybe what you do need. The 2413U is a USB interface with a USB B type connection. It can not interface with an ISY994i as it is strictly a serial port using an RJ45 network style connector and a network cable between the PLM and the ISY994i. Page 17 of this thread has a photo in a response showing both the older and newer version of the serial daughter board. A response on page 19 shows the new version of the serial daughter board. I have seen some excess stock older 2412 PLMs being sold on Ebay by Smartenit. Main board only, Serial and USB. The label on the unit may not be the same as the model you purchased. As exchanging the daughter board. Changed its interconnected type. If in doubt. You can see both types for sale on the Smarthome web site and even download the manuals. The USB model also needs a USB Chip Driver on the computer as the USB PLM has a internal serial to USB chip on its output.

2413U USB PLM? The PLM is not being used by an ISY994i? As it uses a 2413S Serial PLM. The 2450 I/OLinc also the 27 Ohm resistors in it. So you could compare them to your PLM. It also has a switching power supply in it but the DC filter is not the same configuration.

The V1.? 2443 Access Points the white LED will flash on Insteon Tragic. The V2.? don't seem to flash for me. You can always run the builtin 4 TAP/Beacon communications tests between them or any other Dual Band Modules. To see if they can communicate. The checking the Hop count for changes. Should also show some information on if they are helping. The Scene tests may also yield some information. With and without the Access Points in use.

Shorting I4 may help. Both I3/AN1 and I4/AN2 are a high impedance input and subject to noise. Testing mine found that all I had to do was touch the case and if they where not terminated. Resulted in a flood of random message (LED on side flashing) being constantly sent. If the wiring to the dry contacts you are using with I3 are long or near a noise source. I suppose it may pickup noise but the resistor should calm it down.

If the 2443 Access Points are any revision 2. Label on the back should show revision. They are built on the same 2413 base board as the 2413S PLM we use and subject to the same capacitor issues. So your tests may show no added communications issues if removed and already are starting to fail.
