Serial PortsCPU310

The CPU has two independent, on-board serial ports, accessed by connectors on the front of the module.

COM1 and COM2 provide serial interfaces to external devices. Either port can be used for firmware

upgrades. For serial port pin assignments and other details on serial communications, refer to Chapter
