public class RS485Scan
extends RS485ReadWriteServer

A class that provides the possibility to scan a serial port for connected RS485 NuDam modules. Starting with hex-address 00 all addresses up to KEY_MAXADDRESS are scanned in a way that the read-configuration command KEY_CONFIG is sent for each address, a certain maximum time-out KEY_CYCLES turns is waited for an incomming reply. If no reply is received, the next address is scanned. If there was a reply, the answer is checked and the module found is displayed on the command line.
