PREFACE
This manual provides the necessary information for the user to
insta 11 and maintain
the
Perkin - Elmer 2 - Line and 8 - Line
Communications Multiplexors ( COMM MUX ) . The COMM MUX interfaces
the multiplexor bus of a Perkin - Elmer processor system with a
variety of
half
-
duplex
( HDX ) or
full
-
duplex
(
FDX
) a
synchronous
data sets or local terminals . The system conforms to the RS - 232C
transmitters / receivers interface and can be programmed
for
a
variety of baud rates and character formats .

CHAPTER
1
GENERAL
DESCRIPTION
1.1
INTRODUCTION
The
Perkin
-
Elmer
Communication
Multiplexors
(
COMM
MUX
)
are
available
in
two
formats
:
The
2 -
line
COMM
MUX
(
Product
Number
M47-104
)
and
the
8 -
line
COMM
MUX
(
Product
Number
M47-105
) .
The
COMM
MUX
interface
the
multiplexor
bus
of
a
Perkin
-
Elmer
processor
system
with
half
-
duplex
(
HDX
)
or
full
-
duplex
(
FDX
)
a
synchronous
da
ta
sets
or
lccal
terminals
.
The
system
conforms
to
the
RS
-
232C
interface
and
can
be
programmed
for
a
variety
of
baud
rates
and
character
formats
.

SCOPE
This document describes the installation and functional operation
of the COMM MUX and provides useful maintenance information for
digital
technicians who maintain these devices . A block diagram
analysis and a functional analysis of major areas
of each
COMM
MUX ( 2 - line and 8 - line ) are included .
