Working Principle
Number 1, 2, 3, 4 of the dip switch are used to set the address of RS485, 5 is the
reset switch, and 6 is the Terminal Resistance.
Number 5 is the reset switch: dial up and dial down. The machine will restart and
reset successfully
The right side figure shows the address number setting.
Number 6 switch is used to set the terminal resistance in RS485.
Communication: If the 485 communication wire is longer, than 100 meters, it is
needed to set the number 6 dip switch of the last reader to ON state, that is
parallel a terminal resistance of 120 ohm between 485+ and 485-.
