For each byte of information, the Least Significant Bit (LSB) is transmitted first. For multi-byte information, the lower-order byte is transmitted first. External interconnection testing is achieved using an NH1.0-12P terminal wire connector (with locking mechanism) to mate with the NH1.0-12AWB SMD (horizontal mount) connector on the ranging module side. The pin definitions for the power supply and communication interface on the ranging module side are shown in the table below.
