submission by Nigel Garwood – because having my bit woman I chose that it would be a great concept to put our video (Hitachi), DVD (Dansai), Freeview Box (Thompson) as well as Amplifier(Philips) in a cupboard under the stairs.

This was to avoid them being “played with”. To make this a useful service we needed to be able to manage these products from three separate locations; living room, kitchen area as well as bedroom. Our home is wired with CAT5 throughout.

Looking around the offered systems they were either much as well costly or would not totally do the job. with the UKHA_D group I found the firm system. This was originally meant to act as an extension to the Homevision system however Frank McAlinden, who developed FirM, recommended me that it might be utilized as an infrared repeater system.

I purchased one as well as eagerly awaited its arrival from Australia. The set shown up rapidly as well as well packaged as well as included…

FirM Controller

3 zone Rx Units

3 four method zone Splitters

Home Vision / firm male to male lead

3 sample Homebrew stick-on emitters

2 spare fuses

1 Dummy IR Led

The only additional I needed to have was a 12v regulated supply however I already had one of these.

I downloaded the set up file from the site as well as whilst it is mainly aimed at installation with Homevision it was simple sufficient to work out what I needed to do. The set up process went as follows:

I sited the controller under the stairs next to the AV kit. I connected the emitters to the front of each of the bits of set as well as plugged them into one of the 4 method IR splitters. This in turn plugs into the primary Controller. The emitters should not be plugged directly into the controller as the splitter has present limiting resistors.

I linked the receivers in each of the three spaces back to the controller through feline 5 which I plugged directly into the very first three zones on the firm Controller.

The only bit of info I lacked was the truth that I needed to link the IR out port directly back to the IR IN port. These ports would typically link to HomeVision. I then powered it up as well as evaluated it.

I discovered that when a signal was got from a zone receiver the firm Controller zone receiver led (green led) for that zone came on as well as at the exact same time The Tx (red) led’s flashed. The zone Rx Units have 2 led’s: a yellow one to suggest the system is getting IR as well as a red one to suggest that firm is hectic as well as not to send any type of IR….This is useful when a person is sending IR in one zone as well as somebody is in one more zone , they will see the hectic led (red) come on as well as will wait till it goes out before sending any type of IR. The hectic signal is typical to all zones so even the zone that is sending IR has its hectic led come on.

All went well as well as I was able to manage the video AMP as well as DVD player, nevertheless when it concerned the Thompson Freeview box I had problems. I discovered that it would not work whatsoever as well as after investigation discovered that it utilizes 33khz which is outside the variety of FirM. This came as a bit of a strike as this was one of the primary utilizes I had for FirM.

Another issue I had was that I discovered that every so frequently firm would seem to totally lock up. After some investigation I traced this to a “Low Energy” lamp in my lounge. It would appear that it was send out IR which was interfering with FirM, when I replaced the bulb I had no much more problems.

I am pleased with the set general it achieves what I set out to do. The only frustration was that it won’t manage the Freeview Box, nevertheless I am going to look to see if I can modification this to one that will work with it in the future. It was extremely simple to set up as well as the directions were clear.
