ProData II
Device address (RS485)
If multiple devices are connected to each other via
the RS485 interface, a master device can only identify
the devices by their device address. Within a network,
each device must have its own device address.
The device address can be configured via the rotary
switch that is available on the ProData 2. In this way
addresses can be set in the range of 1 to 99.
