A Remote Bus Extender Master Module MRB04XM (Figure 1-1 ) is located in each of the three
-
hand slots of any local extension chassis that is connected via fibre op
right
remote extension chassis. The three Master Modules (A, B and C), together with their
corresponding Remote Slave Modules, provide an interface between the processor modules
(MPPs) in the main chassis, the I/O modules in the extension chassis and the I/O modules in
the remote chassis.
This document is intended to provide a general understanding of the function of the Remote
Bus Extender Master module sufficient to enable basic maintenance operations to be effected
in the field.

TECHNICAL DESCRIPTIO
N
PHYSICAL
Th
e MRB04XM Remote Bus Extender Master Module is a 9U high PCB with integral front
panel. A general view of the main components is shown in Figure 2-1 . DIP switches SW1 and
SW2 are used to set the enable and addresses of up to four remote chassis.
EXTERNAL CONNECTIONS
Each module is plugged into an extension chassis backplane bus system via two DIN41612
connectors J1 and J2 (Figure 2-1 ). The connections to remote chassis are serial links along
fibre-optic cables which plug into ST type transmitter and receiver connections on the front
panel. The top four connectors are the transmitters and the lower four are receivers enabling
two
-
way communication between the master modules and up to four slave modules in remote
chassis.

Connector J1 links the Remote Bus Extender to the I/O modules in the local chassis.
Extensions are provided 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’ are specially extended to enable the installation of

The I/O modules interface to three isolated communications buses (shown collectively as the
‘I/O Bus’ in Figure 2-5 ), each bus being served by one of the Remote Bus Extenders. Columns
‘a’ and ‘c’ of connectors J2 link each Remote Bus Extender to the expansion bus via rear
backplane connectors ‘e’. The same basic chassis is used for the main chassis, the extension
chassis and the remote chassis.
