Newbie question about PLM for ISY-99i

[pisabell]

Hello,

 

I am new to the Universal Devices world and I am planning to buy a used ISY-99i. I checked the manual and it says that I need either a 2412S or 2413S Insteon PLM.

 

But I wonder about the serial port thing. Apparently this is not for connecting the PLM to the ISI because an ethernet connection is provided for that purpose. So this may be because there could be a need to connect the PLM to a computer. However, my computer does not have any serial port. Should I rather get USB PLM? Does this matter from the point of view of connecting the PLM to the ISY-99i? Would a 2414U work OK with the ISY-99i?

 

Thanks in advance,

 

Pierre

The PLM connects between the serial port on the ISY99i and the serial connector on the PLM.

The ISY99i is accessed by its network connection.

Also the older 2412S supplied power to the ISY99i through its serial connector. The 2413S does not have the power on the serial connection and you also have to use the ISY99i's external power input connector.

The ISY99i's firmware had to be frozen at 3.3.10 and all future firmware updates are for the ISY994i series only. So support for new model modules will not be in a ISY99i's firmware.

 

No a 2414U PLC will not work.

To add to what Brian H said…

 

The ISY has what looks like 2 network ports. However, 1 is the serial port (Port A), and 1 is the ethernet port (Network). Don't confuse the two!

Pierre,

 

Thanks so very much for your interest. Please do NOT buy ISY99i as it's no longer supported and you will be wasting your money. Please purchase an ISY994i.

 

With kind regards,

Michel
