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...
