Paul,

Welcome! Obviously you need to pay attention to the physical layer and very carefully to the timings in order for your device to play well with the others. You'll also want to make sure you parse and pay attention to all the fields in the message header properly.

As far as what messages to implement it really depends on you. The absolute minimum required messages are indicated by the "Required" column of Table A-3. For your device, that would be the 3 Discovery messages, DEVICE_INFO, SOFTWARE_VERSION_LABEL, DMX_START_ADDRESS, IDENTIFY_DEVICE. There are some others that are dependant requirements. Meaning they are required if you implement certain other messages, so review the requirements indicated by that column.

Once you get the basic messages working, most find that implementing additional messages is very easy and they often implement as many as they can that are useful for their product.
