Triguard SC300E MPP Processor Module
TECHNICAL DESCRIPTION
Physical
The MPP is a 9U high PCB with integral front panel. Some aspects of MPP operation are
determined by link settings.
External connections
Each module is plugged into the main chassis backplane bus system via two DIN41612
connectors J1 and J2 (Figure 1-1 ). Figure 2-1 shows the main chassis backplane bus
interconnections.
Diagnostic port
A 9 -pin D-type connector is provided on the front panel. The pinout is listed in Table 2-4. The
diagnostic port signals are also available at connector ‘g’ at the rear of the chassis backplane
(Table 2-5).
Chassis backplane
The signals passing through J2 are available at the rear of the main chassis backplane. The
rear backplane connectors are shown in Figure 2-2. For additional information, refer to the
Chassis User Manual (Ref 008-5097).
Connector J1 links the MPP to the I/O modules and is represented on the rear of the chassis
backplane by Area ‘d’. Area ‘d’ consists of extensions to the pins of the J1 mating connector
(96 pins in three columns a, b and c). Pins 07 to 10 of columns ‘b’ and ‘c’ arespecially
extended to enable the installation of the chassis address setting links (see Figure 2-5 ).
Column ‘b’ of connectors J2 links each MPP to the other MPPs via the Inter-Processor
Communications Bus.
Columns ‘a’ and ‘c’ of connectors J2 link each MPP to the expansion bus via rear backplane
connectors ‘e’.
