What is the X2-SDLMC sensor port layout?

The X2-SDLMC sensor ports are labeled to outline the Universal Asynchronous Receiver Transmitters (UARTs) available on the data logger. The sensor ports on an X2-SDLMC data logger are engraved with Sensor 1 and Sensor 2. These ports correspond to the traditional P0 (Sensor 1) and P1 (Sensor 2) ports on other X2 data logger models.
