When you create your SIMPL program, you'll define the various devices within the program. Each is assigned to an IPID. When you compile and load your code, the IP Table is automatically configured on the processor, based on your program. There's an option when loading to let the program update the IP Table, so make sure you allow that. So now, your processor knows what connections to expect (touchpanels and other Crestron devices, including Crestron Connected devices), and what connections to initiate (like TCP/IP connections to other controlled devices). For connections the processor is expecting, you'll need to set your touchpanels (for example) to use the same IPID you defined for them in the program, and point them at your processor's IP address. The touchpanel will initiate the connection, and when the processor sees a device connect on that IPID, it'll say "ah, I've been expecting you, and I know your a touchpanel, and I'm already programmed to know what to do with each join number I might see from you."
