INTRODUCTION

This

chapter

serves

as

an

introduction

to

the

DIGILOG

MASS

STORAGE

UNIT

IV

(MSU

IV).

This

chapter

also

includes

a

general

description

of

the

MSU

IV

along

with

the

list

of

its

characteristics

and

specifications.

1.2

GENERAL

DESCRIPTION

The

DIGILOG

MSU

IV

(Figure

1-1)

is

a

compact,

low

cost

mass

storage

unit

for

use

with

a

DIGILOG

data

line

monitor

(DLM)

or

with

any

vendor's

data

line

monitor.

The

MSU

IV

can

be used by

relatively

unskilled

personnel

and

serves

as

an

extension

of

the

DLM

internal

memory.

The

MSU

IV

can

also

be

connected

to

any RS-232 communication

device

(modem,

terminal,

FEP,

etc.)

for

direct

digital

recording

of

data

and

status

information.

MSU

IV

uses

trouble-free,

nonvolatile

diskettes

to

provide

unattended

data

line

monitor

and

the

subsequent

analysis

of

long

data/control

sequences

(over

400k

bytes).

Recording

or

playback

is

accomplished

in

either

the

standalone

RS-232

or

the

DLM

mode.

When

operated

automatically

at

speeds

up

to

19.2

kbps

on

FDX

lines,

the

MSU

IV

will

determine

the

speed

of

the

line

from

the

data

stream.

Recording

speeds

over

19.2

kbps,

and

up

to

72

kbps,

can

be

selected

manually

by

the

user.

SELECTION

AND

FUSE

REPLACEMENT

MSU

is

normally

shipped

from

the

factory

ready

to

operate

using

a

primary

source

voltage

of

115

VAC,

60

Hz; however,

it

is

designed

to

operate

on

either

115

or

220

VAC

at

50

or

60

Hz.

Use

the

following

procedure

to

check

or

change

the

unit's

operating

voltage

configuration.

Use

Figure

2-1

AND

CONNECTORS

1.

Check

that

MSU

IV's

line

cord

is

not

plugged

into

an

outlet.

2.

Check

the

setting

of

the

rear

panel

voltage

select

slide

switch.

The

number

seen,

either

115

or

220,

must be

in

the

range

of

the

voltage

applied

to

MSU

IV.

3.

Set

the

voltage

select

switch

by moving

the

slide

to

one

extreme

posi-

tion

or

the

other.

If

MSU

IV

is

being

configured

to

operate

in

a

range

of

95V

to

130V,

set

the

switch

to

115.

If

the

unit

is

to

operate

at

voltages

between

190V

and 260V,

set

the

switch

to

220.

4.

Check

the

rating

of

the

fuse

in

the

fuseholder.

If

the

unit

is

con-

figured

to

operate

at

115

VAC,

50

to

60

Hz,

the

fuseholder

must

con-

tain

a

1.5

A

slo-blo

fuse.

If

it

is

configured

to

operate

at

220

VAC,

50

or

60

Hz,

then

it

must

contain

a

0.75

A

slo-blo

fuse.

5.

Change

the

fuse

by

pushing

the

fuseholder

cap

in

and

twisting

it

clock-

wise

to

loosen.

Replace

the

fuse

with

a

fuse

of

the

same

value.

Slide

the

fuse

back

into

the

fuseholder

cap.

Push

the

fuseholder

cap

into

the

fuseholder

assembly

and

twist

counterclockwise

to

seat

it

in

place.

2.3

APPLYING

POWER

Before

plugging

the

line

cord

into

an

outlet,

refer

to

paragraph

2.2

and

verify

that

MSU

IV

is

configured

to

operate

using

the

voltage

supplied

by

the

outlet.

Check

that

the

rear

panel

POWER

switch

is

set

to

OFF

before

plugging

the

line

cord

into

the

outlet.

Apply power

to

MSU

IV

by

setting

the

POWER

switch

to

ON.

MSU

IV

automati-

cally

performs

both

a

test

of

its

light-emitting

diode

(LED)

indicators

(except

for

the

disk

drive

activity

indicators)

and an

internal

diagnostic

self-test

each

time

the

unit

is

turned

on.

Immediately

after

the

POWER

switch

is

set

to

ON,

verify

that

MSU

IV's

front

panel

indicators

light

and

that

the

TRACK/STATUS

indicator

displays

888. A

LED

failure

may

cause

an

incorrect

indication

during

system

testing,

but

this

does

not

mean

that

the

unit

cannot

be

used;

however,

it

does

mean

that

the

indicator

should

be

repaired

as

soon

as

possible.

Upon

completion

of

the

indicator

test,

DRIVE

1,

CONT,

and

TRACK/STATUS

indicators

remain

lit

(the

TRACK/STATUS

indicator

displays

00) and

all

other

indicators

go

out.

If

the

unit

should

fail

the

internal

self-test,

the

TRACK/STATUS

indicator

displays

the

letter

E and a

two-digit

error

message.

Refer

to

Table

2-1

for

a

description

of

diagnostic

error

messages.

During

self-test,

MSU

IV

also

per-

forms a

test

of

its

own

random-access

memory

(RAM)

and

erasable

programmable

read

only

memory

(EPROM).

If

a

RAM

or

EPROM

problem

is

detected,

an

error

message

is

displayed

on

the

TRACK/STATUS

indicator;

refer

to

Table

2-1.
