UART Connector

A 6-pin UART connector is used in conjunction with the opto-isolated UART-to-USB

adapter included with the MultiMotor Series Development Kit to allow the monitoring and

control of the motor from a PC. Figure 7 shows the UART connector pin layout for the

Z16FMC MCU Module.

Table 5 identifies the UART connector pin signals and their functions.

DBG 4 I/O Debug.

GND 5 N/A Ground.

NC 6 N/A No Connect.
