What to configure
The switch S1-1 is used to discriminate between Flash EPROM configuration or DIL-
Switches configuration. If it is set OFF, the DIL-Switches are irrelevant for configuration
purposes. Otherwise, they set the GW-21 parameters as described in the following
section.

Configuration by DIL-Switches
To configure the CPU board by DIL-Switches, the DIL-Switch S1-1 has to be set ON.
When you configure the GW-21 by DIL-Switches you have to:
§ specify which subsystems is connected to each gateway UART;
§ set the baud rate for the installed protocols;
§ set the Cerban vitality telegram option;
§ set the ciphering option, when needed.
4.2.1
Subsystem setting
To specify the type of subsystem connected to each UART you have to use the follow-
ing two tables.
First of all define the DIL-Switches settings: look at Tab. 4 and identify the settings for
the subsystem type you wish to connect to GW-21. For instance, a CS11 requires the
(OFF, OFF, ON) setting.
Then, using the Tab. 5, find out the DIL-Switches that are used by the UART to which
the subsystem is connected; set the three DIL-Switches as specified.
In a GW-21 up to six UART are available and so 18 DIL-Switches are reserved. They
are divided into groups of three. Each group can assume the value corresponding to
the subsystem you want connect.
You must remember that you can have up to table 4 subsystems and up to 2 LMS
lines. These values cannot be exceeded.
