HELP! I have to program a Pronto to switch inputs on an Extron System 7SC. Unfortunately, I do not have the original remote, but I do have a sheet with hex values supplied by Extron. They claim to use an NEC format, but I have no idea how costruct the codes necessary. Any help would be appreciated. I have 7 inputs to switch through. Details I got from Extron are...
NEC Format (uPD 6121g)
Custom Code : 00FFh
Carrier Frequency: 38KHz
Input1: 09
Input2: 0A
input3: 0B
Input4: 0C
Input5: 0D
Input6: 0E
Input7: 0F
I have been trying to figure this out on my own, but am having a hard time...Any and all help would be MUCH appreciated...

In Pronto Hex an NEC signal basically looks like:
900A 006D 0000 0001 stuv wxyz
where you replace stuv with the custom code and replace wx with the command code and replace yz with the computed value FF minus the command code.
So for example, your Input1 is:
900A 006D 0000 0001 00FF 09F6
