Alright, we just ordered 4 of the Motor 393 Integrated Encoder Modules. 2 for the drive, and 2 for the lift. How do I go about programming them? (I am new to ROBOTC).
How/Where do they plug into the cortex? I forgot to buy the extensions, so I’ll need to order those.
Thanks!

Are there multiple ports to plug them into? I have 4 total.
That page helps a lot! Thanks!
No, they are all daisy chained of the I2C port. Read the wiki entry at the link I sent, it explains everything.
an added bonus is that they seem to be more sensitive than the old quad encoders. Awesome!
So, I just have 1 motor to the next, to the next, then to the Cortex 12C port correct?
Yep, the encoder/motor closest to the cortex is unit 1, the next unit 2 etc.
The external red quad encoder has 360 counts/rev, the IME for the 269 motor is only 240.448 count/rev so less resolution. The 393, however, has 627.2 counts/rev in torque configuration and 392 counts/rev in speed configuration so it has more resolution.
The kit comes with a couple, so you shouldn’t need to purchase any extensions for testing/
I just tested the lengths, and we should be fine. I thought we had to go from each IME to the cortex. It makes it shorter daisy chaining them together.
