Need help with Yamaha RX-V1400 A/V receiver

[skyhook8]

Yamaha RX-V1400

Uses NEC1 and has Standard and Extended IR codes (from http://www.yamaha.com/yec/customer/ir_codes.htm). I used Yamaha_RX-V1300.txt which is essentially the same device. It contains only the Standard codes which use the "Main Device" number 122. The Extended codes use the Main Device number of 126.

How do I add the Extended codes to my KM device file? Or do I create a new KM device file, add both devices, and then use key moves to add the Extended codes to the base device?

Thanks for your help.

"Main Device" number 122. The Extended codes use the Main Device number of 126.

So the title you put on the thread is a little misleading. It's two device numbers, one protocol.

How do I add the Extended codes to my KM device file?

There is a combo protocol "NEC 2DEV Combo" specifically for this sort of combination.

Or do I create a new KM device file, add both devices, and then use key moves to add the Extended codes to the base device?

That's probably a little easier and smaller total size within the eeprom. The main factor to choose between the two approaches is whether you're short of KeyMove memory.

Okay, I've changed the protocol to NEC 2Dev Combo and the Device numbers as such:

Protocol Name: NEC 2DEV Combo
Device1: 122
Sub-Dev1: 122
Device2: 126
Sub-Dev2: 126

Then, in the byte2 column of the Functions sheet I've added the corresponding device numbers as in decimal format above.

No worky. I could've tried some different combinations of the above numbers and hex/decimal values but I only had a few minutes at lunchtime to test and thought that there might be a quick answer.

Thanks again for your help.

Protocol Name: NEC 2DEV Combo
Device1: 122
Sub-Dev1: 122
Device2: 126
Sub-Dev2: 126

If there's no sub-device numbers referenced, they should be left blank. You should also specify NEC Style: = 1

Then, in the byte2 column of the Functions sheet I've added the corresponding device numbers as in decimal format above.

The entry in the byte2 column would be '1' for the Device1/Sub-Dev1 pair, or '2' for the Device2/Sub-Dev2 pair. Therefore, something from Device 122 would be '1'; Device 126 would be '2', etc.
