6.3 Serial interfaces
The WebdynSunPM concentrator has three RS485/422 serial ports.
A communication protocol can be associated with each of these ports. All devices on the same serial
port must use the same protocol and the same bus parameters (speed, data bits, stop bits, parity).
The following protocols are available:
