Does anybody know if the new Directv receivers are able to have a second discrete code so I can share a DVR with another HD receiver in the same room?I'm trying to avoid adding an rf receiver with ir routing.

Clarify please...

There are several ID code sets for most receivers.

I may have contributed some of these other sets to the RTI mega code 13 list already. I will have to look tomorrow.

There should be a switch or setting method on the remote depending on the model of receiver or at least somethhing in the manual about it

What I'm trying to do is share 1 HD DVR & 1 HD Receiver to two rooms. With the idea to be able to control either one from either room, without affecting the other. If each receiver has it's own ir codes this shouldn't be a problem.

Each model has one other alternate IR address. The address codes for the HR20 are 00001 & 00003. where the H20 addresses are 00001 & 00002.

Of course you can have infinite # of receivers set to RF.

You bring up an interesting point, Edmund. In the (very) old days of DirecTV I had a Sony SAT-A4 receiver that would work with RF. It's problem was that if your neighbor had one you could both be controlling each other's receivers. It (RF) proved to be worthless because in fact my neighbor had the same receiver.

So is RF control of the HR20 and H20 linked to one specific receiver and incapable of even accidentally controlling another receiver nearby? How (in simple terms) are they doing that? My curious mind wants to know.

Thanks

Yes, you marry the remote to a particular receiver by using the receivers unique receiver id #, the 6 digits of it.

You can marry one remote to more then one RF receiver, upto 3 on the white remotes, by marrying it to particular device key on the white remote.

Edmund,
How do I change these "unique" ir codes in the receivers and on the remotes? Once I do I assume I can learn them into my computer so I can then put them into my remote for each room.

To switch a HR20, start by programming code 00003 to either AV1 or AV2 device on the white remote, switch back to the dtv symbol device and enter the menu:

1. menu> settings> setup> remote> receiver mode>
2. you will see either DIRECTV or AV1/AV2, click whichever to reveal both
3. press AV1/AV2, the remote won't work any longer, switch to av1 or av2 whichever has code 00003
4. press done

To switch the H20 just substitute in code 00002 for 00003.

To switch a receiver and remote to RF:


1. menu> settings> setup> remote> IR/RF>
2. you will see IR or RF, click whichever to reveal both
3. press RF
4. Done, the remote won't work any longer, do the following on the remote:

a) dtv device
b) press and hold MUTE & SELECT for two blinks
c) enter 0 0 0 0 1

d) dtv device
e) press and hold MUTE & SELECT for two blinks
f) enter 9 6 1
g) press CH UP
h) enter the last 6 digits of the receiver ID #, found on a sticker in the access card compartment
i) press SELECT

Edmund could you try these directions one more time. You lost me at number 2 above. I want to have the HR20 at one code and the H20 at another code. After changing the codes, how do I program the on/off to my mx-700. I am willing to pay you a consulting fee, if you think the level of detail I am requesting merits this.

Urgent help Needed. My remote does not work now. I followed step 1 but did not read the instructions carefully enough. I did not start by programming code 0003 to either AV1 or AV2. Can this be done now or am I SOL. I am trying to set my HR20 and H20 to respond to different on/off commands. I have two remotes, one has been programmed and the other has not. I can't get my HR20 to respond to any commands after my mistake.

The Sonys could be set to any one of sixteen RF codes. As I went around setting them up, I realized this, only because I went from place to place doing it, and just set each next customer's unit to the next number, and never set one to 1 again. The RF then wasn't worthless. Oddly, it was much slower than IR, though.

My simple answer is that they're not, or at least I'll bet not.

You can program the device on the remote for any code wish at anytime you wish. If you're listening to messages at the bottom of the screen, don't.

Program the dtv symbol device with code 00001:

1. dtv
2. press and hold MUTE & SELECT for two blinks
3. enter 0 0 0 0 1

Program av1 on the remote with code 0 0 0 0 3

1. av1
2. press and hold MUTE & SELECT for two blinks
3. enter 0 0 0 0 3

What device works the HR20, DTV or AV1?

switching codesets is a two-stage process, receiver & remote.

You were supposed to enter the menu of the receiver, steps 1-4 were to direct you through the menu, the remote was already supposed to have been programmed with code 00003. steps 1-4 were to get the receiver to recognize code 00003.

Edmund, I was able to go back and program the reciever to 00003 and then I followed the rest of the prompts. I've almost got my remote just the way I want it, but there are some situations where my JVC TV is on and if I switch from the already on HR-20 to the HR20 with a discrete ON command for the HR20, then I have no problem. But if I turn on the HR20 first the discrete ON command does not turn my TV ON. This is not a big issue as I usually turn on my HR-20 first anyway. But I'm trying to make it bullet proof for my wife.
