Bob Cat,

Does the FoxSat HDR have discrete on and off IR codes?

If there are, can you make them available in HEX format so that they can be loaded onto my Nevo SL universal remote?

Cheers

John

Hi I have a Pronto

I use "0" which will bring the Humax on & sleep to turn off

I dont believe Discrete codes exist

Re Dave

...or if they aren't currently available, could it be added to a future firmware release, for all of us with Universal Remotes?

Second or thirded, the hdr's pickup angle on IR is so narrow mine often misses the 'OFF', so goes off next time I want it 'ON'.

I use the auto power off and power on, but then my watching is normally quite regimented, so to speak.

I have asked their tech support manager about this in the past and he told me that the codes don't exist.

I use zero for on and toogle pwr for off.

I've done some work as part of a completely unrelated project and can tell you that the HDR remote uses the extended NEC IR protoco, as described at the bottom of this page:
http://www.sbprojects.com/knowledge/ir/nec.htm

If you'd have asked a cople of months earlier I could also have told you the address that the HDR is programmed to use, but it shouldn't take long to cycle through them to suss out the correct one.

If desired I can get my kit back together and tell you the address that is used, as well as some of the command codes for the various remote commands.

I'm a bit lost following this thread.

Could somebody explain in laymans terms what these discrete "on" and "off" codes are for, and what they do

Thanks

Most remote controls have a power on/off button which "Toggles". Push once for On, Push again for Off.

This is no good for Universal Remotes which, for example, control a number of devices at the same time. This is because they, say, want to turn all the devices On at the same time. For this to work reliably, with "Toggle" type commands it is necessary to know whether the device is already On or Off (very difficult/impossible to determine automatically). For this reason it is much better if the universal remote can be programmed with discrete On/Off commands which the devices can understand and respond to.

I hope this is clear.

It means that a specific IR code is sent for 'on' and a specific code sent for 'off'.

The Humax remote is sending one command from the remote when pressing the on/off button. If the box is on, it will turn it off, if it is off, it will turn it on.

This can cause problems in areas such as home automation, where multiple 'ons' or 'offs' need to be sent to ensure that the signal is received before sending the next command.

Some receivers can receive a 'discreet' on or off even though the remote doesn't have such buttons.

Thanks for that explanation, I fully understand it now. I did not realise the thread was refering to universal remotes.

Thanks again
