Chapter 3
Power On
DFS150-485 operation in three-modes, Master Private, Master Modbus and Slave Modbus
modes. All these modes are valid after a start-up communication period followed the power on
period T_(Power_on). During the start-up communication period T_(startup_comm), operation
mode is fixed in Slave Modbus ASCII mode, all triggers are invalid. This period can be extended
by sending arbitrary valid command to the scanner, and user may communicate with scanner in
the extension communication period as long as they want until reboot or send software reset
command.
If no command is received within T_(startup_comm), ten seconds, it will switch to the scan mode
set by user previously. The default scan mode is Slave Modbus ASCII mode. After set all
parameters, DFS150-485 provides two ways to update the setting: reboot or send software reset
command. The behaviors after T_(startup_comm) are shown below.
