Question: What are the wires that come out of the repeater box?  CAT 5, IR eye, and something else?  How is the repeater powered?
Document: An excellent product! This IR repeater is the best. It's receiver box is small enough to mount behind a flush mount flat screen and the eye is sensitive enough to work from across the room. CAT-5 is super cheap to make the long runs you need and setup was a breeze. The price is a bit higher but you definitely get what you pay for here. Five stars!
This is my second IR repeater system, works great. Really like the CAT-5 Option, as it provides a lot of flexibility in terms of positioning. You decide how far away the sensor needs to be from your equipment, including in another room in the house entirely.
The Hot Link Xl Cat-5 IR Repeater works very well. This product is rather small and fragile looking. I was afraid of breaking the IR transmit wires during install and had some trouble finding the right placement on equipment as well, but the struggle was minimal. Cat 5 option was used for I moved my local installed equipment to closet on opposite side of Wall. Now it is more easy to access the equipment and installation is no longer cable cluttered. The placement of the IR receiver was rather difficult.
Purchased the second Hot Link XI CAT-5 for the living room after having installed the first one in the home theater. Easy install and works well. The only problem encountered on both units was the tape used to attach the emitter to the equipment. Its backing just did not come off the emitters. Solved this by using some double sided clear tape.
No issues so far. Used to relocate cable box to the basement. Will recommend this product to anyone looking for an IR Repeater.
I'm a pro and normally use Xantech and similar IR extenders. Never had an issue with these...till now. I burned a week thinking I had an IR communication issue with an AT&T; STB (Cisco IPN-330HD box from Haydes) solved and then it would come back and then solved, etc. Just couldn't get consistent communication through a Xantech IR receiver and block.
Great Service!The IR eye on the unit is ridiculously sensitive and requires some care when mounting to make sure you are not getting stray IR from lights or the TV or anything else. They are not joking when they say put it behind the TV. All of my remotes work great with it mounted behind the TV from anywhere in the room.
I have tried it with a Scientific Atlanta cable box, and a Samsung DVD player with no problems at all. Every available button on the remotes gets transmitted perfectly. The only thing I'd suggest is a way to tone down the sensitivity of the receiving IR eye. Bright scenes on the plasma tv would make the blue LED blink (meaning that it was receiving an IR signal). As would fluorescent lighting. Once I covered the receiver up with a post it, it works perfectly.
Used this repeater to transmit my remote signals from my living room to the closet in another room where i put all my electronics. I used a 20 ft Cat 5 cable along with this repeater and it works just as advertised.
I purchased a new panisonic plasma which I mounted over my fireplace. Took my cable box and blue ray player and installed in my guest room 38 feet away. Purchased this ran a 50 ft cat 5 cable in my attic. Mounted box behind tv and connected the cable. Works great first time! No tweaking!!! This is awsome!
Answer: The something else is a blue confirmation LED. Only the repeater is powered by the included dc supply. The receiver is powered via utp.
