In a CBS-3 up to six UART are available and so 18 dip-switches are reserved (Actually
only four of them are available). They are divided into groups of three. Each group can
assume the value corresponding to the subsystem you want connect.

You must then set the communication baud rate according to the suggested proto-
col/baud rates (See section 6).

Cerban vitality telegram
The dip-switch S1-2 has the optional function to filter the Cerban vitality telegram; the
dip-switch is valid for all of the Cerban line which are defined on the gateway.
The only reason to filter the vitality telegram is to limit the traffic of messages to the
LMS station(s). Note that if the vitality check is enabled at LMS level, then this dip-
switch must be set to ON, else LMS will generate false fault events.

Configuration by Flash EPROM
If you have the configuration EPROM, you have to set OFF the dip-switch S1-1. The
default configuration for this dip-switch set is for EPROM
not
installed, so you actually
have only to verify the settings.
Even if the Flash EPROM configuration is enabled, you must set the communication
baud rate with subsystems using the dip-switches and according to the suggested pro-
tocol/baud rates (See section 6).
