Control Operator's Reference Manual

Chapter

1

Introduction

This

chapter

provides

an

overview of Control Operatorlevel

commands

and

describes

the

fonnat

of

the

reference section

in

the

following

chapter.

Control

Op

Commands

The

Control

Op

commands

pennit

the

repeater's Control Operators to enable

and

disable

various

repeater

functions

and

to place

the

repeater

into

its

various

modes

ofoperation.

They

pennit

the

Control Ops to comply

with

FCC regulations

regarding control

and

regulate

the

day-to-day

usage

of

the

repeater

and

its

features.

A full

complement

of

independent

commands

are

provided

with

each

function or

mode controlled independently

of

other

functions

or

modes.

The

Control Op

commands

are

always available for modifying

the

state

of

the

controller.

Macro

Sets

There

are

over two

hundred

Control Op commands. To simplify day-to-day

operation,

the

controller

can

store

ten

complete

sets

ofControl Op

setup

information.

These

Macro

Sets

are

stored

by

the

repeater

owner

in

non-volatile

memory.

They

permit

the

Control Ops to. in effect, execute a

set

of

commands

with a single code.

Macro

Set

#0

is

special

because

it

is

always selected

by

the

controller

on

powerup.

The

repeater

owner

can

defme exactly how he'd like

the

repeater

to

power

up

in

case

power

is

lost

to

the

system

and

no

battery

backup

is provided.

Scheduler

In addition to

manual

selection of

the

Macro Sets

by

the

Control OPt

the

repeater

owner

may

define time

and

day-of-week changeovers to

the

different Macro Sets.

This provides for fully automatic, scheduled operation of

the

repeater, simplifying

the

chores

for

the

repeater's Control

Ops

and

enhancing

the

service prOvided

by

the

repeater

system,

See

the

Operation Manual for details

on

the

Scheduler.

Command

Control Op Touch-Tone

commands

may

be

entered from

any

of

the

repeater's

command

channels

the

the

receivers,

the

owner

to

security.

Control Operator's Reference Manual

Response

Messages

The controller

responds

to Control Op

commands

in

one of

three

ways:

(1)

It

may

provide a

unique

response

message for

each

command, verifying

that

you've

entered

the

command you intended.

(2)

It

may

respond

with

a programmable "generic" message, acknowledging

entry

ofa Control Op level commanc:l

without

identifying which

command

was

entered.

This

mode

enhances

sy~te!ll

security

by

providing no clues

as

to

what

your

command

accomplished.

(3)

It

may

provide no

response

of

any

kind.

The

response

mode

is

selectable with one

of

three

Control Op commands.

The

generif

response

message

may

be

programmed

by

the

repeater

owner

using

the

message editor (Programming Reference Manual).

The.response

is

provided to one ofseveral

channels

depending

on

the

command

input

channel.

Control

Op

Prefix

and

Root

Set

The Control Op

command

codes

consist

of

a prefix,

which

is remotely

programmable

by

the

repeater

owner, followed

by

three-digit

root

codes defined

later

in

this

manual.

The prefix

may

be

between one

and

seven digits long

and

can

include Touch-Tone 0-9,

*,

and

A-C. The Control Op

commands

therefore

may

be

between four

and

ten

digits long. The entire

command

is

sent

as

one

sequence, i.e., prefIX-root. Long

commands

enhance

security;

short

commands

are

easier to remember. The

command

code prefix

and

root

set

selection

can

be

changed

at

any

time

by

the

repeater-owner.

Four

complete

sets

of root codes

are

available

and

one

of

the

four is selected for

use

by

the

repeater

owner.

The

ability to change to a different root

set

enhances

security

by

allowing

the

repeater

owner to completely

change

the

command

root

codes. Ofcourse,

he

can

change

the

prefix

at

any

time

as

well.

Control Operator's Reference Manual

User

Mapped

Control

Op

Commands

The

repeater

owner

may

specify

up

to

ten

Control Op

commands

to

be

available

as

User

level

commands,

with a

separate

command code prefIx. This allows

users,

or

another

level

of

Control Operator. to access a small

set

ofControl Op

commands

without

the

need

to widely release

the

Control Op prefIX

and

root

codes.

The

User

Mapped Control Op command

is

descnbed

in

detail

in

the

Programming Reference Manual.

Command

Entry

From

the

Telephone

When

entering

commands

over

the

air.

the

controller knows you're done

entering

tones

when

it

sees

your

carrier drop. It

then

evaluates

the

Touch-Tone

command

you've

sent.

When

controlling over

the

phone.

there's

no

"carrier" to

drop.

It

therefore

is

necessary

to terminate a Touch-Tone

command

with

the

#

key.

which

serves

as

an

"Enter" key. When

the

controller

sees

the

#.

it

evaluates

and

acts

on

the

command

you've entered.

For

example.

if

the

Control Op command

is

4932031.

it

should

be

entered

over

the

telephone

as

"4932031#".

An

alternate

Control

Op

prefix

can

apply to control over

the

telephone.

For

example.

it

may

be

deSirable to include fourth column keys for

the

"over

the

air"

code prefIX

to

enhance

security. Since

there

is

no

fourth

column

on

most

Touch-Tone

phones.

however.

you

may

want

to stick to

the

12 keys

on

a regular

phone.

The

repeater

owner

can

define

the

telephone Control Op prefIX to

be

the

same

as

the

over-the-air code

or

to

be

different.

If

you

make

a

mistake

when

entering a command over

the

phone. simplywait a

few

seconds

to allow

the

command decoder's interdigit

timer

to clear

the

command

buffer before proceeding. The interdigit timer value is programmed

by

the

repeater

owne

and

is

typically

set

at

approximately

five

seconds.

Remarks

The

Purpose

This

command

allows a Control Op to synchronize

the

time-of-day clock

seconds

to

an

accurate

time source.

Remarks

If

the

"seconds

hand"

is

at

less

than

30,

this

command

resets

seconds

to zero. If

it's

greater

than

30,

minutes

are

incremented

by

and

seconds

set

to

zero.

The clock

has

a cumulative

error

due

to fmite

accuracy

and

temperature

drift

in

its

time

base.

This

command

proviqes a simple

way

to

periodically

adjust

the

clock.

Example

We

noticed

that

the

clock is off

by

about

20

seconds.

and

enter

the

Clock

"straight

to synchronize

the

Note

If

the

must

be

Purpose

To select

Remarks

The controller

can

respond

to

each

Control Op

command

with

a

unique

acknowledgement to verify

that

the

intended

command

was

entered. Or,

as

an

alternative,

it

can

respond

with a programmable "generic" message,

such

as

a

Morse "dit-dit", simply to acknowledge

that

a Control Op level

command

was

accepted.

The

generic

response

is

useful

if

you're concerned

about

someone

trying.to

monitor

your

control activities. Finally,

the

response

can

be

completely

inhibited

so

there's

no

clue

that
