4.3.10 Serial Ports
Configure the three serial ports, two ports on the SOC and one legacy port.
Feature Description Choices Default
COM1 Controls and configures SOC Serial Port #1. This
port supports RS232, RS485, and RS422
protocols. If using the CBL-SER2-202-12A cable
assembly, this port corresponds to the J2
connector.

• Slew Selects UART slew rate. All drivers can be slew
limited to 250 kbps to minimize electro-magnetic
interference (EMI) by selecting the Limited option.

• Receiver
Termination
Selects UART cable receiver termination: no
termination or 120 ohms. The receiver inputs are
high impedance when termination is disabled.
NOTE: Only available for RS-485 and RS-422
modes.
