1.2. System Configuration
Figure 3 Backplane Front View
The backplane contains a user-configurable setting for system identification. In the Trusted
TM
Expander Chassis, this setting represents the system number 0 to 15. The setting is implemented via
three 4-position DIP switches (IDA, IDB and IDC) and is provided to the Trusted
TM
TMR Processor
connector. Adjacent to the three DIP switches is a table which shows the required settings for each
system. See Tables 1 and 2 below.
Note: On some early models of Trusted
TM
Expander Chassis, the designation of the ‘Off’ and ‘On’
switches detailed in the table on the backplane was reversed.
In all cases, ‘1’ = Off and ‘0’ = On and ‘down’ means logic 1.
All three address settings must be the same, otherwise an error condition will be reported.
The first expander chassis should be set to IDA=2, IDB=2 and IDC=2, the second expander chassis
should be set to IDA=3, IDB=3 and IDC=3. The last expander chassis should be set to IDA=8, IDB=8
and IDC=8.
