AR-FX4 SIMULATION - 6

Set the signal send level to 0dB or the soft SW set value, and specify
one dial to be delivered to.

The DTMF signal of the specified dial number is delivered until the
interruption command is provided by pressing the [BACK] key.) When
another dial number is specified during delivery of the signal, the new
dial number is delivered.

The signal send level is returned to the soft SW set value before exe-
cution of the mode after completion of the mode.

Note: Executable only when the FAX is installed.

The following FAX information is printed.

Note: Executable only when the FAX is installed.

When the relay state of the polarity reverse relay, the external tele-
phone hook switch is changed, the content of change is displayed
regardless of the soft SW setup. The display of change is kept until an
interruption command is supplied by pressing the [BACK] key. 

Note: Executable only when the FAX is installed.

The data received from the line are checked to insure that the following
reception data are identical to the judgment data. If identical, "OK" is
notified. If not, "NG."

A judgment is made according to the reception start data. Continuous
coincidence is required.

Note: Executable only when the FAX is installed.

The send/receive test is performed, and the time required for send/
receive of the image data in the test is measured and displayed.

When there are two or more send/receive operations of image data in
one communication, only the time of the last send/receive data near
the end is measured.

Note: Executable only when the FAX is installed. 

The following test sound is delivered to the line and the speaker to
adjust the sound kind and volume.

The send level to the line is the set value of soft SW.

The set values of the selected sound kind and volume are written to
each soft SW.

System error

Used to print the system error log (error

system error log is always stored as the 
ring buffer in the SRAM 256byte area.

Protocol monitor

Regardless of soft SW19-1 status, the 
protocol monitor of the preceding 
communication is printed. (Printing is 
allowed at any time before starting the 
next communication.) For this operation, 
the protocol monitor of one 
communication is always buffered.

2. Internal process

1) Used to check if the installed expansion memory is ready to use.

If  an  expanded  memory  is  available,  write  the  target  data  of  the
SRAM. 

2) After  completion  of  writing,  management  information  is  written  to

the management information block.

3) For the management information, refer to the table below. 

However, the FAX program version No. area is written into the data
version no. area (FFF0 - FFFF). 

*TEST pattern

Recognized that the card normally reads the next data.

In normal cases, when installation of an expanded memory is detected
after  turning  ON  the  power,  the  expanded  memory  is  cleared.  When,
however, there are some SRAM data in the expanded memory, it must
not be cleared. When the ROM data name (FED0 - FFDF) in the man-
agement  information  of  the  expanded  memory  is  "REGISTRATION,"
the expanded memory is not cleared.

AR-FX4 SIMULATION - 8

1) After  checking  the  data  in  the  management  information,  reading

from  the  expanded  memory  and  writing  into  the  SRAM  are  per-
formed.

2) After completion of writing into the SRAM, the expanded memory

is initialized for normal use again.

3) After  completion  of  initializing  the  expanded  memory,  the  SRAM

RESTORE operation of the simulation is terminated. 

1) Before  saving,  install  the  expanded  memory  to  be  used.  (During

power OFF)

2) In the SRAM backup menu (66-53), SRAM BACK UP is selected,

and the process to save SRAM data into the expanded memory is
executed.

3) After completion of saving, turn off the power.

1) Install the expanded memory into which data are written according

to the above procedures. (During power OFF)

2) In the SRAM backup menu (66-53), SRAM RESTORE is selected

to write the SRAM data which was saved into the expanded mem-
ory into the SRAM of the FAX board.

Note: Executable only when the FAX is installed.
