This worked as advertised. I like the old model (which this one is replacing since that one stopped working...) better since it could supply power as well. These devices are so big, it is tough to also have to plug in another module to get an ISY going.
PHILLIP -- charlotte, NC   12/7/2012
Operating as expected. No issues.
RONALD -- manitowoc, WI   7/19/2012
After ordering and before receiving my ISY994i the information I read said I would need a power supply that was not provided with the unit. I ordered this and only later found out that they are indeed included! Now I have a spare.
KIRK -- toney, AL   3/15/2012

First one was defective, Smarthome replaced it quickly, new one works as advertised.
CHRIS -- huntington station, NY   11/10/2011
plug didn't fit ISY
NATHAN -- pheonix, AZ   7/4/2011
Documentation/website should be more clear, especially on the isy99 page that a power supply is required with the newer PLMs.
BENJAMIN E -- dane, WI   3/31/2011
Plug and play. I think this .87 cent part should come with the ISY, but that's just my 2 cents.
JEFF -- w st paul, MN   3/10/2011
Does not fit ISY 99 Ir Pro. Barel plug is too small!!
PHILIP -- corrales, NM   3/5/2011
As expected.

It works. Better price then from UD.
RICHARD -- toluca lake, CA   11/27/2010
Does not fit the new Universal Devices ISY-99/IR Pro. Another adapter is needed.
BRIAN D -- philomath, OR   11/20/2010
Plug does NOT fit correctly into socket. Too big.
JOSEPH -- van nuys, CA   9/16/2010
Power plug into ISY does not fit properly older ISY units.
BRIAN -- killingworth, CT   6/24/2010
DC connector end. Fit very tight on my ISY99i's DC Input. Thought it may break.
JOHN -- lexington, SC   6/14/2010
Your company is great Customer service is job one. Thanks for everything.We tell everyone
CLAUDE -- rockledge, FL   6/12/2010
Works as it should. This is needed for the ISY if you will be using the new Dual Band PowerLinc Modem (2413S) since it will not supply power to the ISY. Only the non Dual Band will supply power to the ISY.
