Basic device question

I have an Axcent3 master with a variety of devices (projector, DVD, etc) attached via RS-232. I am looking at some code I have inherited and am trying to learn my way through it. When assigning device numbers in the master program, how does the master know which physical device to send it to? I can't seem to find any code that links a device the programmer defines to a specific RS-232 port. So, if I send a command to device number 5001, what does the master do to make sure it goes to the device that I have assigned as number 5001 and not another one? I apologize if I'm missing something obvious here...the only I could find was a document containing recommended device numbers from AMX, but that still didn't seem to explain the issue I'm curious about.

Thanks for your help.

    If you're using an Axcent3 master, that means you're programming in Axcess, not Netlinx. Each port is its own device.

    The RS232 ports are devices 1 through 6, the Relay is device 7, the IR ports are devices 8 through 13, and the I/O is device 14.

    In Netlinx, each of those numbers would be a port on the device, but in Axcess they're actually treated as devices.

    Ahhh...thanks, I figured I was missing something simple :)
