This is an easy process that requires several steps. The only trick is to do the last 2 steps quickly enough, and you have to know how to find the Settings portion of the PS3's menus (the XMB).
1) Remove power from the IR2BT box -- remove the batteries if you are using batteries or remove power from the USB cord if that's how you are powering it.
2) Attach the original PS3 game controller to the PS3 and use it to power up the PS3 (by pressing its PS button).
3) Use the Crestron to turn on the rest of your system so that you can see the PS3's menus (the XMB) on your TV. If necessary, now switch the Crestron to a page that lets you send a "2" key command to the PS3 as if getting ready to type in a number.
2) Using the original PS3 game controller, find and select the option in the PS3's Settings for pairing a new Blu-Ray controller. This will replace the pairing already in there that was set up for the original IR2BT (the PS3 remembers only one such Blu-Ray controller pairing at a time). You now have about 30 seconds to complete the rest of this process or you will have to select this Settings option again.
3) Immediately restore power to the IR2BT. Make sure the IR2BT is positioned so that it can see the IR command light coming from the Crestron. Your installer likely placed a little IR emitter near where the IR2BT was set up, perhaps even taped to the IR window of the IR2BT itself.
4) Within 15 seconds press and hold down the "2" key on your Crestron until the TV screen changes to indicate that the PS3 is now registering a new Blu-Ray controller. The "pairing" is now complete.
NOTE 1: The IR2BT will treat a long "2" command as a re-pairing command like this only during the first 15 seconds each time it is given power. If you don't send the long "2" command to it fast enough you will need to remove power from the IR2BT and start over -- and by this point you will also likely need to re-select the Settings option in the PS3 itself (using the original PS3 game controller) to initiate a new pairing again.
NOTE 2: The PS3 will put up a message saying to press a different key combo for pairing. Those are the instructions for pairing Sony's optional BlueTooth Blu-Ray controller. To pair the IR2BT, use the long "2" key command as described here instead.
Place your IR2BT where you would like it for normal use. Make sure it can still see the IR emitter coming from the Crestron.
That's it! The pairing will be remembered from here on out even if you turn off the PS3 or if the IR2BT loses power.
