4.2. Soft switch function description
SW1 No. 1, No. 2 Receive mode
Used to select the reception mode (AUTO or MANUAL) for receiving
faxes.
SW1 No. 3 ~ No. 6 Reserved
SW1 No. 7 Sort copy function
Used for sort copy.
SW1 No. 8 Reserved
SW2 No. 1 Forced 4800bps reception
When line conditions warrant that receptions take place at 4800 BPS
repeatedly.
It may improve the success of receptions by setting at 4800BPS. This
improves the receiving document quality and reduces handshake time
due to fallback during training.
SW2 No. 2, No. 3 CED tone signal interval
For international communication, the 2100Hz CED tone may act as an
echo suppressor switch, causing a communication problem. Though
this soft switch is normally set to "0", it should be set to "1" so as to
change the time between CED tone and DIS signal from 75ms to
500ms to eliminate the communication problem caused by echo.
SW2 No. 4 ~ No. 6 Reserved
SW2 No. 7 Footer print
When set to "1", the date of reception, the sender machine No, and the
page No. are automatically recorded at the end of reception.
SW2 No. 8 Reserved
SW3 No. 1 Reserved
SW3 No. 2 CSI transmission
CSI signal contains the sender's phone number registered in the
machine. If this switch is set to "1", no sender's name will be printed at
the receiving side.
SW3 No. 3 Action when RTN is received
The operation is set when the RTN signal is received in the G3 trans-
mission mode.
SW3 No. 4 Reserved
SW3 No. 5 Pulse format
Used to set the pulse number when actually dialing for the dialed num-
ber (N).
SW3 No. 6 DIS receive acknowledgement during G3 transmission
Used to make a choice of whether reception of NSF (DIS) is acknowl-
edged after receiving two NSFs (DISs) or receiving one NSF (two
DISs). It may be useful for overseas communication to avoid an echo
suppression problem, if set to 1.
SW3 No. 7 Non-modulation carrier for V29 transmission mode
Though transmission of a non-modulated carrier is not required for
transmission by the V29 modem according to the CCITT recommen-
dation, it may be permitted to send a non-modulated carrier before the
image signal to avoid an echo suppression problem. It may be useful
for overseas communication to avoid an echo suppression problem, if
set to 1.
SW3 No. 8 Default file format for network scan
SW setting the default of the compression format and the file type
required for generating the image data from network scanned data.
SW4 No. 1 Protocol monitor
Normally set to "0". If set to "1", communication can be checked, in
case of troubles, without using a G3 tester or other tools. When com-
munication FSK data transmission or reception is made, the data is
taken into buffer. When communication is finished, the data analyzed
and printed out. When data is received with the line monitor (SW-4 No.
8) set to "1" the reception level is also printed out.
SW4 No. 2 Line monitor
Normally set to "0". If set to "1", the transmission speed and the recep-
tion level are displayed on the LCD. Used for line tests.
SW4 No. 3 Reserved
SW4 No. 4 Sender's information transmit
When it is set at 0, sender's name, sending page number and so on
are automatically printed in the recording paper on the receiving side
during transmission. Thus, the sender can be known on the receiving
side.
SW4 No. 5, No. 6 Reserved
SW4 No. 7 H2 mode
Used to determine reception of H2 mode (15 sec transmission mode).
When set to OFF, H2 mode reception is inhibited even though the
transmitting machine has H2 mode function.
SW4 No. 8 ECM mode
Used to determine ECM mode function.
SW5 No. 1 ECM MMR mode
MMR (Modified MR) selects presence of the compression function.
SW5 No. 2 ~ No. 5 Signal transmission level
Used to control the signal transmission level in the range of -0dB to -
31dB.
SW5 No. 6, No. 7 Reserved
SW-5 No. 8 Key tone
Used to select whether or not to sound the key tone.
SW6 No. 1 ~ No. 4 Recall interval (FAX)
Choice is made for a recall interval for speed and rapid dial numbers.
Use a binary number to program this. If set to 0 accidentally, 1 will be
assumed.
SW6 No. 5 ~ No. 8 Recall times (FAX)
Choice is made as to how many recall times should be made. Use a
binary number to program this.
SW7 No. 1, No. 2 Reserved
SW7 No. 3 Dial mode
Switch the type according to the telephone circuit connected to the
facsimile.
SW7 No. 4, No. 5 Reserved
SW7 No. 6 CNG detection
When setting to "1", the CNG signal detection function.
