UX-B800A
2 – 36
4.2. Soft switch function description
SW1 No. 1, No. 2 Reserved
SW1 No. 3, No. 4 Receive mode
TEL, FAX or TEL/FAX mode is set.
SW1 No. 5 ~ No. 8 Reserved
SW2 No. 1 Reserved
SW2 No. 2 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. 3, No. 4 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. 5 ~ No. 8 Reserved
SW3 No. 1 Length limitation of receive
Used to set the maximum page length. To avoid possible paper jam,
the page length is normally limited to 1.5 meters for receive.
SW3 No. 2 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.
SW3 No. 3 ~ No. 6 Reserved
SW3 No. 7 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. 8 Action when RTN is received
The operation is set when the RTN signal is received in the G3 trans-
mission mode.
SW4 No. 1 Reserved
SW4 No. 2 Dial pausing (sec/pause)
Pauses can be inserted between telephone numbers of direct dial con-
nection. Selection of 4 sec or 2 sec pause is available.
SW4 No. 3 Pulse format of D.P.
Used to set pulse format of D.P. mode.
SW4 No. 4 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.
SW4 No. 5 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.
SW4 No. 6 Reserved
SW4 No. 7 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. 8 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.
SW5 No. 1 ~ No. 8 Reserved
SW6 No. 1, No. 2 Reserved
SW6 No. 3 Digital cable equalizer for reception
Digital cable equalizer for reception
0: OFF
1: ON
SW6 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.
SW6 No. 5 ~ No. 8 Reserved
SW7 No. 1 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.
SW7 No. 2 Reserved
SW7 No. 3 ECM mode
Used to determine ECM mode function.
SW7 No. 4 ECM MMR mode
MMR (Modified MR) selects presence of the compression function.
SW7 No. 5 ~ No. 8 Signal transmission level
Used to control the signal transmission level in the range of -0dB to -
31dB.
SW8 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.
SW8 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.
