I just got a Denon 3803 for my Home Theater. My installer says the Denon doesn't have the discrete codes necessary for him to program my Pronto the way he normally does. He said he can program it, but it will take him longer and not work as well as other AV recievers would. (He mentioned Yamaha.) This stuff is all greek to me. Is he right?

No he is incorrect. Here is a link to the Denon website where they actually list their IR command set for your exact model and there are discrete On and Off commands listed as well as direct input commands for DBS, VDP, etc.

[Link: usa.denon.com]

I wouldn't expect everyone to be able to interpret these commands but here is a brief explanation:

For the AVR3803 there are three system addresses (01000, 00110, 00100)

and a set of tables like this:

SYSTEM ADDRESS(C1 C5) : 0100, EXTENSION BIT(C12,C13) : 11
No. Data (C6 C11) Key Name

1 100000 POWER

System address is what we call device and the bits are backwards, in this case it is 01000 binary or decimal 2. The others are (00110 (really 01100) is decimal 12 and 00100 (00100 either way) is decimal 4)

The individual commands are a little harder. We consider Denon to use an 8-bit key code=OBC=function and it is (C6 C11)and (C12,C13): in this case:

100000 11 but again the bits are backwards so transposing:

11 000001 or 128+64+1= 193

and that is the OBC for power. You can also use the windows calculator pick view|scientific and the radio button for binary enter the ones and zeros then radio button for decimal.

With this information you can use a program like MakeHex and generate the Pronto hex using the Denon.irp protocol.

This file for the 5803 should have everything you need.

will these codes work for the 3802??

I haven't analyzed it but it is likely since dwg is a regular here who knows what he is talking about and most Denon equipment shares much of the same comamnd set.

Yes the 3802 is a subset of the 5803 codes. That file has an excel spreadsheet, as well, with the listing of all the codes-you could cross reference with the 3802 codes from the denon website- but as I remember the discrete input commands, power commands and tuner presets will work. The discrete fader commands will not however.

You should tell your programmer to spend a day or two in this site!!! I guess you can give him the address

So do you guys know if the discrete fader commands work on the 983 I should probably have found out before I promised the client?

Yes the 0, -20, -40 discretes work on the 983. This file will have them:
