The earlier firmware did have a separate access program made for it. I don't have have exact version where the launcher did access the later firmware in an ISY994i The latest firmware for an ISY994i is 5.3.4

NO. The 2414U or 2414S are not a PLM. The 2412U 2412S 2413S and 2413U. Are the PLM models. They are the original PLC Power Line Controller. That we could compose programs and download into them to run alone. Using the SALAD assembler we got in the original Developers Group. Use a completely different set of commands and will not work where a PLM is needed. Also if you are using a 2412S make sure only three wires are in the cable are being used. The 2412S has unregulated +12VDC on one of the pins. Normally are around 18VDC to about 19.5VDC

The 2450 I/OLinc is power line only communications. You may have some new power line issues. Like a signal sucker or power line noise maker. The trouble shooting link information may give some insight on what the problem maybe. It is also possible it has failed. As it has a switching power supply and the same capacitor issues we see in the 2413 PLM. I have seen different capacitors Smarthome tried to help but can't say exactly what yours may have,

The replace function would work if the replacement is a similar model. To do it you add the replacement with a new name. Then high lite the old one and pick the replace with function. Using the name you gave the new module. If it is a new power line only. It could take eight messages and acknowledgement to add one link to the replacement. So it would take awhile and if you have a power line noise issue. It may fail. If the new one is dual band replace may or my not be an option. As it may not be close enough for a swap.

Is it dual band or the power line only keypad?

I also don't think the 2477D or 2477S are not being gotten rid of. I also seen some of the ones that where not available. Being brought back along with the improved PLM. Both USB and Serial.

Do you have an eisy or polisy? That module is supported by their later firmware. If you are still using an ISY994i is it not supported by its latest firmware before being discontinued.

One other fact. There is going to be an eisy price increase in early May. https://www.universal-devices.com/price-increase/

Try power cycling one of the switches. You can pull out the Set button to turn off the switch power then push it in to its normal position. Do NOT go past the normal position or you may factory reset it. You may also go into the Administrative Console and see how many links are in it and the PLM. That may give you a clue. Restoring one of the problem switches and testing may also show something.

Latest for an ISY994i is 5.3.4. In the ISY994i area not any Polisy or eisy areas. I also feel do not try any updates until you get into the ISY994i. If everything us working OK I would also say do not do it. https://forum.universal-devices.com/topic/33287-534-isy994-last-release-for-isy994/ https://forum.universal-devices.com/topic/24381-iox-launcher/#comments

Then you have a chance to get a different module if you care to. I do know early ones had a history of failing and I don't know if they ever fixed it.

Turning on a high capacity relay does sound like a go way to go. Elk made a heavy duty 220VAC relay in an enclosure. With a 120VAC relay coil in an enclosure. Controlled by a On/Off module or any other similar module. Not sure if it would be anything you can use. https://www.elkproducts.com/product/heavy-duty-relay-contactor-9200/ Insteon sales site shows a 220VAC controller. https://www.insteon.com/load-controller

Sounds like a good point. Way back machine here. Early Developers days. We where able to get modules at the wholesale distributors price but had to promise not sell them.

Some versions may not have the Jumper Header. Just two solder pads where it was mounted on the PC board. In the early manuals. Was to set the reduction in sensing field. Jumper On is reduced sensitivity. The small jumper block was many times on one of the two pins on the PCB. Some have used the power connector in them to run them on an external USB power supply. They are supposed to not have to go into the power saving mode on an external supply.

That also crossed my mind.

If it is like the one never seeing the light of day in the FCC Database. It would have a larger faster Link Database; faster processor clock, more universal power supply. Like 120 220VAC 50 60Hz.

Make sure the PLM is totally booted before you power up the eisy. If it is like the older ISY994i PLM detection is during its boot up.

The sticker should also have a revision number on it. That also may give us information on the PLM.

The 2413S and older 2412S PLM use a unique cable. RJ45 to a DB9S connector. Only three wires are used. Serial In; Serial Out; common and in a unique pin out . The other pins are different signals like TTL in and out and the older 2412S also unregulated +12VDC normally around 18.5VDC. To be safe do not connect any other wires to the RJ45 PLM serial connector. Other than the three signals the serial PLM uses.

I agree. Electrician has made a incorrect statement. You need the actual voltage the lights are wired to, type of lights, maybe the current they use and the wattage. If the shop gets warm I may think of halogen or fixtures using vapor discharge. More data is needed to even see if an Insteon switch is capable of safely controlling them directly or maybe controlling a contactor to then control the lights.

Actually there was a 0-10V dimmer module. That was discontinued and now one is being brought back. No info on if it is the same one or a new design.

Have not seen it lately. We use to have LED bulbs that had a repetitive current spike and in rush current at startup. Manufactures gave us a figure to calculate the wattage we should use when we added up wastage to see if we where maybe overloading a dimmer switch. I remember a few said use 80 watts. 😀

Adding a dual band module. In the pass trough outlet is a good move as the I/OLinc is power line only. Adding the pass through module was recommended by Smarthome and now Insteon company.

Not sure if it has changed but we have seen brand new directly from Insteon modules. Having factory test links in them and a factory reset was need. Many here actually factory reset all our new modules before using them.

The new PLM sounds very interesting.
