Thank you both for the information!

I don't see a downloadable document available for the ISY994i/IR PRO. I was only able to find the isy99_userguide.pdf. Does this document cover all of the models? I just ordered the ISY994i/IR PRO. It appears that I'll need to purchase a "few" other things to get started. The information available on the site, and in the document, indicate that I'll need to purchase the 2412S or 2413S PLM. I assume that also applies to the ISY994i/IR PRO. Between those two PLMs are there any advantages? Which is the best option? I do have power supplies, so that isn't an issue. Can I do better with something else? Thank you.

Hello, I hope someone can answer a few questions. Is the ISY994i series, and the ISY994iZ series, based on the same hardware? if so, can the ISY994i be later upgraded to the ISY994iZ? If I had a Zigbee enabled ISY994i or ISY994iZ device, would I be able to communicate with a custom-built Audrino-based device with an XBee radio? The description for the ISY994i indicates "An expansion slot which could be utilized to install and support other communications protocols such as a Zigbee radio". What is currently available, that can be installed, that would allow me to communicate with a Zigbee device? Thank you!
