Selector

1:

ECP

mode

The

ECP

mode

enhances

the

normal

bidirectional

communications

between

the

facsimile

equipment

and

the

connected

PC

for

higher

transmission

speed.

•

Selector

2:

Recovery

from

inactive

PC

interface

If

the

facsimile

equipment

recognizes

via

the

STROBE

signal

line

that

the

connected

PC

is

powered

off,

then

it

will

turn

the

PC

interface

output

Low

to

protect

the

PC

from

hazards

that

could

be

caused

by

weak

electric

current

accidentally

fl

own

from

the

equipment.

This

selector

determines

whether

the

equipment

should

recover

from

the

inactive

PC

interface

to

normal

interfacing

state

upon

receipt

of

data

from

the

PC.

•

Selector

3:

PC

power

-off

recognition

time

This

selector

sets

the

time

length

from

when

the

equipment

detects

the

PC

powered

off

until

it

recognizes

the

detected

state

as

power

-off.

If

selector

2

is

set

to

"0,"

it

is

recommended

that

selector

3

be

set

to

"1":

otherwise,

the

equipment

may

mistakenly

detect

PC

powered

off.

•

Selector

5:

Escape

from

phase

C

This

selector

determines

whether

or

not

the

equipment

will

escape

from

phase

C

when

it

detects

an

RTC

(Return

to

Control)

in

non

-ECM

mode

or

an

RCP

(Return

to

Control

Partial

page)

in

ECM

mode.

•

Selectors

6

through

8:

Lower

limit

of

frequency

to

be

ignored

after

detection

of

calling

signals

(Ci)

At

the

start

of

reception,

if

the

equipment

detects

the

frequency

of

calling

signals

(Ci)

specified

by

selectors

1

through

4

of

WSW14,

it

will

start

the

ringer

sounding.

When

doing

so,

the

equipment

may

fail

to

detect

the

calling

signals

normally

due

to

noises

superimposed

at

the

time

of

reception.

To

prevent

it,

use

selectors

6

through

8

of

WSW36.

If

the

equipment

detects

higher

frequencies

than

the

lower

limit

specified

by

these

selectors,

then

it

will

regard

them

as

noise

and

interpret

that

detecting

state

as

being

normal,

allowing

the

ringer

to

keep

sounding

(until

the

equipment

starts

automatic

reception

of

FAX

data

if

in

the

FAX

mode

or

enters

the

TAD

mode

if

set

in

the

TEL

mode,

according

to

the

preset

number

of

ringers).
