To set the I/O serial port from port 1 to port 2, see Setting the I/O serial port to RS485 on page 29.
If you need a two-wire RS485 after setting the I/O port to serial port 2, Hewlett Packard Enterprise
recommends that you use an external USB-to-RS485 adapter. For more information and examples for
validating the MODBUS protocol communication, see Validating the MODBUS protocol
communication on page 31.
