Mercedes LIN Bus

I have my RealDash about ready to deploy into my car. However, I want to add one more feature, and that is to interface a 2016-18 C-Class MB steering wheel. I have one on the bench, and have figured out the wiring for the LIN bus. I have a LIN → RS232 transceiver hooked up, and it does seem to pass data. However, I have not figured out the data rate. Does anyone happen to know what that might be? Later, I have an Arduino (Teensy 3.2) based board with LIN and CAN onboard, and will use that to translate the LIN commands to RD CAN.
