thanks guys,
some info here i need to read up on.
i have 3 rooms i want to be able to control everything from, but .... that's complicated in itself, as the rooms have different equipment... 2 are easy and a 4 device remote would suffice. the last room, no I would need a higher device remote, but I was holding off on that until i had an understanding of it all on an easier scale.
I only have 1x ofa remote... (at the moment...

)
as for the multiplexor... just to ensure i understand right. the device buttons are sat / tv / dvd etc...
if the upgrades for my devices are all loaded (and available) into the remote. pressing sat (once the unit is programmed) would allow me to control all 4 from the screen that then showed...
ok, so if i understand that right then....
pressing select & blue on the original sky remote puts it into a special mode whereby it only controls 1 of the sky boxes. i choose 0-3 & that then programs the remote to always control that box, unless i perform this function again. all corresponding IR codes from this remote are then routed by the SPC4 through the corresponding numbered outlet / receiver.
pressing select & yellow then tells it wether i am controlling a sky digibox, sky+ or skyHD box (depending on the age / version of the original remote) again the remote stores this programming, until i perform this function again.
so i could then using an ir widget collect those codes.... ok understand that....
but...
if the sky boxes are 1x digibox, 1x sky+ box & 1x skyHD box, then the device codes would / should be different...
so in this scenario, would the multiplexor still put all 3 sky device codes + 1 technomate receiver code onto the sat button? or if because they are all different device codes, would i need to keep them seperate?
I'm sorry if i am asking really noob / dumb questions. please bear with me lol... I am trying to get a clear understanding of it before i plan out what i need / need to do lol...
The reason for doing this (incase you wondered) was to ensure my kids are watching things that are suitable & have some control over it from the comfort of my workshop / lounge / bedroom... ie the 3 rooms which will have a jp1 compatible remote... eventually lol) also besides the kids, I work from home & while the wife watches soaps / chatshows & how to walk a dog, i can put something decent on from another reciever lol
The signal issue i have now resolved, I've taken a split from one of the outputs & run a new cable, working fine now

but hence no diagram yet .... cabling keeps changing / keeping me busy.....
oh, i have phone programming cables which convert usb to serial, a DKU=5 & CA-53 cable... i also have a generic USB to serial cable... do you think i could easily use on of these & just re-model the pin end?
oh, while i think of it... controlling all 3 sky boxes from the multiplexed device button.... say for example 2 of the boxes have record / playback... if the device codes are different, but i am only pressing 1 device button to get to that remote menu, how would it know which one to playback / record on? would i assign 2 buttons for playback & record? one for each box?
thanks & sorry again if i'm being overly thick lol
