Assignment of the Address on the Network
The addresses can be configured from 0 to 99. However the following addresses are
reserved:
 0 to 1: for the DP masters,
 2 to 99: for the slaves.
When assigning the addresses, each slave and/or master must be assigned to a
specific and unique address. A configured address is acknowledged at boot-up. It
cannot be modified if the cover is not removed.
NOTE: The default factory setting is the address 2.
NOTE: Any change to the Splitter Box address shall be taken into account only once
it is powered on again.
Automatic Transmission Speed
At power up, the Splitter Box is in listening mode in order to adapt its transmission
speed to the one used on the network. As soon as it is detected by the master, it
receives its configuration and settings data. Once the configuration is over, it is
operational and ready to exchange data.
Transmission Speed and Cable Length
Each transmission speed has a corresponding cable length.
The following data is indicated without a repeater and with a maximum of 32 slaves
on the segment.
