BUS TERMINATION

The activation (DIP1 → ON) of the bus termination is made via DIP switches on the
circuit board. In the default configuration, the bus termination is deactivated (default).
STATUS LEDS
The communication is indicated by two status LEDs (above right).
Telegrams received without errors are indicated by the green LED 'ok' lighting up.
Faulty telegrams or triggered Modbus exception telegrams are indicated by the
red LED 'err' lighting up.
BUS PARAMETERS
The parameter assignment (bus address, baud rate, parity, mode) is made
via the display menu. In the default configuration, the following values are set:
Address = 1 / Baudrate = 9600 / Mode = 8N1 (default)
