#21638 - 02/23/10 10:24 AM To send an IR command

I'm trying to write a code to control the transmission of IR learned commands from an Ocelot to A/V devices. In the CPUXA protocol I see the SEND RESIDENT IR data packet, I think it is the function I have to use. Valid numbers for IRnumber data are 0 through 39. That's the point. I don't understand why there is not 1024 available IR codes.

It is very important because I have a lot of devices to control by wired IR commands.

I just looks like the document is not exctly right in the description. The command syntax itself show that you have 2 bytes, msb and lsb, and this is the command used by C-Max itself in the IR utilities, which allows you to send all 1024 IR codes.

I have a couple related questions:

1. So the docs show the "Send Resident IR" command's IRNumber parameter's value range is 0-39, and you are saying that the docs are wrong and the value range should be 1-1023? (You actually said 1024 codes, but I assume you really mean 1-1023 since it is my understanding that #0 is reserved)?

2. Since there is the "Send Resident IR" command and the "Send Remote IR" command, I assume that the "Send Resident IR" command sends the IR directly from the Ocelot and it does not support zones?

1) This needs to be updated. When the Ocelot (originally called the CPUXA) was released, it was limited to 0-39 (we had less memory at that time). It is 1-1023 now.

2) Yes, Resident IR means transmit the IR command locally.
