Global Cache for Dummies guide?

I'd really like to set up a universal remote, and I haven't the foggiest clue how these Global Cache gateways function. I've looked at the Global Cache website, watched tutorials on the iRule website, on the MyURemote website, searched through YouTube videos, and I'm not finding any basic information.

Right now I just want to be able to control in my kitchen my Samsung TV, Yamaha sound bar (IR) and my FireTV; and in my living room an old Vizio TV (IR), Apple TV, and an older LG Blu-Ray player.

I'd need a gateway for both rooms, correct? I'm not sure how the line of sight works on the gateways? Where do they need to be located in relation to the AV equipment?

Can anyone point me to a basic setup tutorial?

    Maybe I can answer some of your questions. Let's start with a typical Global Cache unit, the iTach IP2IR. This unit has only 5 connections. The 1st to a wall wort transformer for power. The 2nd for a network cable to connect to your home network. The last 3 connections are for ir emitters. They are named Port 1, Port 2, and Port 3.

    IR emitters are small cables with a plug on one end that connects to the iTach. The other end is a small plastic piece that has an led in it. You peel a small piece of paper off of it and stick it on your component over the ir receiver. You can also get ir emitters with 2 emitters on 1 cable. With these you can control 2 components from 1 port, useful when you have more than 3 components.

    There is also a special emitter called an ir blaster. The ir blaster is not stuck on 1 component, it is positioned in front of several pieces of gear, and can control multiple components within its range. The trick is to find somewhere to mount it in front of the equipment. The ir blaster can only be used on Port 3, and you must configure the iTach to use the ir blaster.

    Note that with ir emitters, you do not need line of sight for control. Components can be in a closed cabinet, an equipment closet, or another room.

    The iTach IP2IR comes with the power plug, 2 ir emitters, and an ir blaster. I'm not sure if it includes a network cable.

    So how does this work? When you tap a button in iRule, it sends the command over your wifi to your network, and from there through the network cable to the iTach. The iTach receives the command and sends it out one of the ir ports to the emitter, which flashes the command to the component.

    In theory, you could control both of your rooms with 1 iTach by using tthe ir blaster in 1 room for all 3 components, and the ir emitters in the other room. You would probably need at least 1 ir blaster with 2 emitters (Amazon) and some ir extension cables. It would probably be simpler for you to use an iTach in each room.

    If you can't run a network cable to your equipment locations, you could use the iTach WF2IR, which uses wifi instead of a wired connection. There are also iTach Flex models you could use. The iTach Flex units are smaller, but the principles are the same. You would need to buy a splitter cable to have 3 ir ports.

    Good Luck!

    OK, so I ordered the wired iTach, and I'm confused. If the wired IR emitters need to be attached to the back of the unit, and the other end to the AV equipment, how can it be used in multiple rooms? My router is in my living room, but across the room from the AV equipment in that room. I can't drag an ethernet cable across the floor.

    I'd love to see pictures of how people set these things up in their homes.

  • You can either place the iTach near the AV equipment, and feed it either via Ethernet of Wi-Fi depending on the model; OR

    place the iTach near the router and extend the skinny cables of the IR emitters.

    The emitters draw very little current, so we have successfully extended their cables as much as 50 feet with small (AWG#26) cables.

  • My dog chews on cables. Alas, I'm going to have to return this unit.

  • In some cases you can VERY CAREFULLY pry off your baseboards and hide the cables behind them. Baseboards can be brittle, so they will crack easily. I use a putty knife to get started. This is probably not an option if you are renting.

    An iTach WF2IR might be a better solution for you. I prefer a hardwire solution, but sometimes that is just not possible.

    Using 1 iTach in multiple rooms will normally require running cables through walls, crawl spaces, attics,etc. I guess you would do it to save money, but after buying the extra cables, you might not save much. One situation where might be pretty simple is two rooms that are next to each other and the equipment is on the common wall.

    Once you get the WF2IR and power it up, you need to connect to it for the first time and assign an IP address to it. It is HIGHLY RECOMMENDED to use a static ip. If you allow DHCP in the router to assign a random ip, it will work fine until there is a power outage, router software update, or you reboot the router, when it may assign a different ip to the iTach. This will "break" your iRule system until you figure out that the iTach's ip has changed, and reprogram all your iRule Gateways to the new ip. Very annoying!

    This webpage explains how to initially setup the WF2IR iTach:

    If you google home networks or home ip addresses first, these instructions may be easier to understand.

  • I have my iTach IP2IR in a media closet with a blaster. I blast a x10 powermid transmitter and in turn the transmitter sends the IR signal wirelessly to individual reciever in each room. The receivers then flash the IR to my TV's. For this configuration you would need one transmitter and one receiver for each room that you have IR components in. The x10 powermid receivers are blasters so they cover the whole room. They also plug in so no need for batteries. They works great , no delay. It helps if your components in each room are from different manufacturers because if components across rooms share the same codes you will be turning on / off and controlling multiple devices at the same time when that might not be the intention.
