1 DESCRIPTION

This

section

describes

the

DRU,

the

various

DRU

antennas,

and

the

AC/DC

power

converter

(accessory

item).

1.1 Digital Remote Unit

The

DRU,

shown

in

Figure

1,

serves

as

the

cellular

user

servicing

unit

for

the

Digivance

ICS.

The

DRU

consists

of

an

electronic

circuit

board

assembly

that

is

mounted

within

a

powder-

coated

sheet

metal

enclosure.

The

DRU

is

designed

for

use

within

a

non-condensing

indoor

environment

such

as

inside

a

building.

All

controls,

indicators,

and

connectors

(except

the

antenna

connector)

are

mounted

on

the

DRU

front

panel

for

convenient

access.

Figure 1. Digital Remote Unit

The

DRU

is

equipped

with

four

integral

mounting

feet

that

allow

it

to

be

mounted

on

any

flat

horizontal

or

vertical

surface.

A

typical

location

for

mounting

the

DRU

would

be

above

ceiling

tiles

(where

the

optical

fiber

and

power

cables

can

be

concealed)

or

on

a

wall.

Slots

are

provided

in

the

mounting

feet

for

securing

the

DRU

to

the

mounting

surface.

The

RF

signal

interface

between

the

DRU

and

the

cellular

users

is

provided

through

an

external

antenna

connected

to

an

SMA

connector.

The

antenna

may

be

ordered

separately

from

ADC.

Several

types

of

antennas

with

various

patterns

are

available.

Non-ADC

antennas

may

also

be

used

with

the

DRU

to

meet

various

application

requirements.

The

DRU

is

equipped

with

a

small

form

factor

LC

type

optical

transceiver

that

provides

a

point

for

connecting

the

optical

link

cables.

Depending

on

the

application

requirements,

the

optical

transceiver

may

be

connected

to

either

a

DHU

or

a

DEU.

The

DRU

is

equipped

with

a

female

RJ-45

jack

that

provides

a

point

for

connecting

a

DC

power

cable.

The

DRU

is

powered

by

34

to

48

Vdc

power

which

is

supplied

through

the

RJ-

45

connector.

Power

to

the

DRU

may

be

supplied

by

the

DHU,

DEU,

or

by

a

120

Vac

to

48

Vdc

power

converter

(available

separately

as

an

accessory

item)

plugged

into

a

properly

grounded

120

Vac

outlet.

The

AC/DC

converter

is

a

UL

Listed

stand

alone

Limited

Power

Supply

(LPS)

unit

with

a

rated

output

of

48

Vdc

at

1.2

Amps.

When

powered

by

the

DHU

or

DEU,

a

category

3

or

5

twisted-pair

cable

terminated

with

RJ-45

connectors

is

required.

The

recommended

maximum

length

of

the

power

cable

is

500

meters

(1,641

feet).

Any

distance

beyond

500

meters

requires

local

powering

by

the

AC/DC

converter.

The

DRU

user

interface

consists

of

the

connectors

and

the

LED

that

are

provided

on

the

DRU

front

and

rear

panels.

2.2 Unpacking and Inspection

This

subsection

provides

instructions

for

opening

the

shipping

boxes,

verifying

that

all

parts

have

been

received,

and

verifying

that

no

shipping

damage

has

occurred.

Use

the

following

procedure

to

unpack

and

inspect

the

DRU:

1.

Open

the

shipping

carton

and

carefully

unpack

the

DRU

from

the

protective

packing

material.

2.

Check

the

DRU

for

broken

or

missing

parts.

If

there

are

any

damages,

contact

ADC

Telecommunications

(see

Customer

Information

and

Assistance

section)

for

an

RMA

(Return

Material

Authorization)

and

to

reorder

if

replacement

is

required.

2.3 Frequency Band Selection Procedure (1900 MHz DRU Only)

The

1900

MHz

version

of

the

DRU

may

be

configured

to

operate

at

any

one

of

four

frequency

bands.

A

DIP

switch

is

provided

on

the

underside

of

the

DRU

for

selecting

the

required

frequency

band.

Use

the

following

procedure

to

set

the

DIP

switch

to

provide

the

required

DRU

frequency

band:

1.

Determine

the

required

frequency

band

for

the

DRU

(AD,

DBE,

BEF,

or

EFC)

as

specified

in

the

system

design

plan.

2.

Orient

the

DRU

as

shown

in

Figure

6

and

then

locate

the

small

opening

in

the

bottom

of

the

DHU

that

provides

access

to

the

band

select

DIP

switch.

3.

Use

a

non-conductive

probe

to

align

the

DIP

switch

sliding

handles

to

provide

the

required

frequency

band

(see

Figure

6).

4.

Place

the

copper

sticker

provided

with

the

DHU

over

the

small

opening

that

provides

access

to

the

DIP

switch.

Note:

The

copper

sticker

provides

EMI/RFI

shielding.

Do

not

use

some

other

type

of

material

to

cover

the

DIP

switch

access

hole.

2.4 DRU Mounting Procedure

The

DRU

may

be

mounted

on

any

flat

vertical

or

horizontal

surface.

A

slot

is

provided

in

each

of

the

four

mounting

feet

for

inserting

a

fastener.

The

fasteners

must

be

provided

by

the

installer.

Use

the

following

procedure

to

mount

the

DRU:

Warning:

Wet

conditions

increase

the

potential

for

receiving

an

electrical

shock

when

installing

or

using

electrically-powered

equipment.

To

prevent

electrical

shock,

never

install

or

use

electrical

equipment

in

a

wet

location

or

during

a

lightning

storm.

Note:

To

insure

that

all

optical

connectors

and

transceivers

remain

dust-free

during

installation,

leave

all

dust

caps

and

dust

protectors

in

place

until

directed

to

remove

them

for

connection.

1.

Obtain

the

appropriate

fasteners

(lag

bolts,

screws,

wall

anchors,

etc.)

for

securing

the

DRU

to

the

mounting

surface.

2.

Position

the

DRU

on

the

mounting

surface

in

the

specified

location

(per

the

system

design).

Make

sure

the

LED

will

be

visible

when

the

unit

is

mounted.

Note:

To

ensure

there

is

adequate

air

circulation

for

cooling,

provide

a

minimum

of

3

inches

(76

mm)

of

clearance

space

on

all

sides

of

the

DRU

(except

the

bottom).

In

addition,

at

least

one

surface

of

the

DRU

installation

area

must

be

open

to

the

building’s

interior

air

space.

If

a

portable/flexible

antenna

will

be

installed,

allow

a

minimum

of

9

inches

(229

mm)

clearance

along

the

surface

with

the

antenna.

Note:

In

mounting

situations

where

fiber,

power,

and

coaxial

cable

pass-through

holes

are

planned,

it

is

critical

that

these

holes

be

placed

far

enough

away

from

their

respective

connectors

to

avoid

forming

overly

tight

bend

radii.

Tight

bend

radii

can

damage

fiber

optic

cable

and

reduce

RF

signal

levels.

The

DRU

mounting

template

(part

#

1154319)

provides

the

clearances

for

the

following

cable

types:

Power

cable

(cat

3

and

5):

0.2

inch

(5.2

mm)

diameter

Fiber

optic

cable

(twin

lead):

0.12

inch

(3.0

mm)

diameter

Antenna

coaxial

cable:

0.16

inch

(4.0

mm)

diameter

If

planned

cable

diameters

are

greater

than

those

listed,

please

consult

with

the

cable

manufacturer

to

determine

the

cable’s

recommended

minimum

bend

radii.

3.

Mark

the

location

of

the

mounting

holes

and

of

any

pass-through

holes

that

may

be

required

for

fiber,

power,

or

coaxial

cables.

Observe

any

additional

instructions

that

may

be

printed

on

the

template

such

as

the

recommended

fasteners

and

clearance

requirements.

2.5 Antenna Mounting Procedure

Various

types

of

antennas

are

available

from

ADC

for

use

with

the

DRU.

All

antennas

include

a

6-foot

(1.8

m)

long

50-ohm

coaxial

cable

for

connection

to

the

DRU.

Each

type

of

antenna

provides

a

specific

coverage

pattern

in

order

to

accommodate

the

shape

of

the

area

where

coverage

is

required.

Mount

the

antenna

in

the

location

specified

in

the

system

design

plan

and

orient

according

to

the

coverage

pattern

required.

Note:

To

comply

with

Maximum

Permissible

Exposure

(MPE)

requirements,

antennas

must

be

installed

to

provide

at

least

20

centimeters

(8

inches)

of

separation

from

all

persons

per

FCC

47

CFR

Part

2.1091.

Separate

procedures

are

provided

for

mounting

and

installing

each
