All LED outputs are active high and should be connected as shown in the picture below. The
resistor values should be chosen to get even light between different LEDs.

Network Configuration Switches
Modbus registers 0x5200 (Application switch 1) and 0x5201 (Application switch 2) can be used
for network configuration. Application switch 1 is generally used to configure the node address
and application switch 2 to configure the network baud rate.
It is recommended to provide means for the end user to set the values of these registers, using
physical switches like DIP switches, rotaries etc. The application is responsible for reading the
switch values and then writing them to Modbus registers 0x5200 (Application switch 1) and
0x5201 (Application switch 2).
If the application processor does not have sufficient input pins to connect physical switches,
there is a mechanism for I/O expansion that can be used. The switches are then connected to
the Anybus CompactCom B40 Modbus Serial instead. For more information see
.
Please refer to the applicable network appendix for a description of the contents of the registers.
