INTRODUCTION AND TEC
HNICAL DATA
PURPOSE
A Remote Bus Extender Slave Module MRB01XS (Figure 1-1 ) is located in each of the three
right-hand slots (A, B and C) of a remote extension chassis. Fibre optic cables link each
MRB01XS to a corresponding master module (MRB04XM) in a local extension chassis. The
master
and slave modules operate together as part of an interface between the I/O modules in
the
remote extension chassis and the processor m
odules (MPPs) in the main chassis.
October 2005
Figure 2-2 shows how the MRB01XSs are linked by fibre optic cables to the MRB04XMs and
then
by
ribbon cables to the MPPs.
This document is intended to provide a general understanding of the function of the MRB01XS
suff
icient to enable basic maintenance operations to be effected in the field.
The chassis that contains the MRB01XS will be referred to as the ‘remote’ chassis throughout
this
document.

TECHNICAL DESCRIPTIO
N
PHYSICAL
The MRB01XS Remote Bus Extender Slave Module is a 9U high PCB with integral front panel.
A general vie
EXTERNAL CONNECTIONS
The MRB01XS is plugged into the remote chassis backplane bus system via two DIN41612
connectors J1 and J2.
Connections to the associated master module are via fibre-optic cables which plug into
transmitter and receiver connections on the front panel.
w of the main components is shown in Figure 2-1
