4 INSTALLATION

4.1 General

The desktop

Controller

unit should be

installed

location

convenient

to the operator. The

ontroller

contains a single RJ-11

connector,

which is used

for

both

power and data

connections.

In most

applications,

the supplied 3 m (10 ft)

power/data

cable is

connected

directly

to the supplied

interface

unit. The

interface

unit

converts

the RS-232 data

generated

the

Controller

unit into

Allegiant

biphase control

code.

The

interface

unit also

provides

a path to

connect

power to the

Controller unit.

An LED

visible

on the top cover of the

interface unit

will flash to

indicate

that the RS-232 data coming

from

the

Controller

has

successfully

been

converted into

biphase control

code.

There are no video

connections

to the

Controller. The

video signal(s) from the camera site(s) should

connected

to an

appropriate viewing

monitor, or

other

video

processing equipment (switcher, multiplexer,

etc.).

If the

application

will utilize an RS-232

data

communication

link, or will be

connected directly to

RS-232 Series

AutoDome

cameras or RS-232

Allegiant

Receiver/Driver

units, the

installation

is done

without

using the supplied

interface

unit. For

232

applications,

an LTC 8557 Series Remote

eyboard

Hookup Kit should be

purchased

simplify the

installation

process. One of the junction boxes

supplied

with the LTC 8557 Series Kit can then be used

connect the RS-232 wires TX and GND from

the

Controller’s

output to the

user-supplied

232

communication

link. The RS-232 protocol requires

simplex

link

operating

at 9600

baud.

Three

installation

sections are detailed

below; select

the type of

application

you will be

using.

This

document

also includes

various diagrams of

typical applications,

that will be helpful to refer

during

installation.

4.2 Installation Using Biphase Code

(See Figures 3 and

)

Install the supplied

interface

unit in a location

enough to the

Controller

unit so the that

supplied

3 m (10 ft) data cable can be used. Note that

the

interface

unit is rated for indoor use only. If

desired,

four holes are

provided

for

mounting

the

interface unit

to a flat surface. The power supply (to power

the

Controller

and

interface

unit) should also be located

a convenient

location near the

interface

unit.

onnect

the

bayonet

style

connector

of the power supply

cable

into the jack located on the side of the

interface

unit.

the power supply cable must be

attached

to the

power

supply, the

polarity

is not

important;

the

Interface Unit

is not

polarity sensitive.

Plug the power supply into

suitable AC power

source.

Connect

the supplied 3 m (10 ft) data cable with

two

RJ-11

connectors, between

the

Controller

unit and

the

interface

unit. The

orientation

is not

important

either

end may be

connected

to either

device.

The next step is to connect the biphase control

code

outputs of the

interface

unit to the data

cables.

Typically,

a single camera site

receiver/driver

can

connected

to each output, but the outputs of

the

interface

unit are rated to handle up to eight (

)

receiver/drivers

when

connected

in a daisy

hain

configuration,

to a

maximum

of 1.5 km (5000 ft). In

daisy

hain

connection,

the cable is looped

through eac

AutoDome

camera or

receiver/driver

along the

way

The last (and

only

the last) unit in the daisy

hain

connection

should be

terminated.

All other

receiver/

drivers should have the

terminating

resistor

removed

when the looping cable is

connected.

Connect

shielded

twisted

pair cable (Belden 8760

equivalent) between

the camera site

receiver/

driver

location and the biphase output

connections

located

the

interface unit.
