FO-77U UX-66U · Soft switch function description
SW-A1 No. 1 Protect from echo Used to protect from echo in reception. SW-A1 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. SW-A1 No. 3 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. SW-A1 No. 4 Length limitation of copy/send/receive Used to set the maximum page length. To avoid possible paper jam, the page length is normally limited to 0.6 meter for copy or transmit, and 1.5 meters for receive. It is possible to set it to "No limit" to transmit a long document, such as a computer print form, etc. (In this case, the receiver must also be set to no limit.) SW-A1 No. 5 CSI transmission (CSI TRANSMISSION) is a switch to set whether the machine sends or does not send the signal (CSI signal) informing its own telephone No. to the remote fax machine when information is received. When "nonsending" is set, the telephone No. is not output on the remote transmitting machine if the remote transmitting machine has the function to display or print the telephone No. of receiving machine, using this CSI signal. SW-A1 No. 6 DIS receive acknowledgment during G3 transmission Used to make a choice of whether reception of DIS(NSF) is acknowledged after receiving two DISs(NSFs) or receiving one DIS (two NSFs). It may be useful for overseas communication to avoid an echo suppression problem, if set to 1. SW-A1 No. 7 Non modulated carrier for V29 transmission mode Though transmission of a nonmodulated carrier is not required for transmission by the V29 modem according to the CCITT Recommendation, it may be permitted to a send nonmodulated 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. SW-A1 No. 8 Reserved Set to "1". SW-A2 No. 1 ~ No. 4 Modem speed Used to set the initial modem speed. The default is 9600BPS. It may be necessary to program it to a slower speed when frequent line fallback is encountered, in order to save the time required for fallback procedure. SW-A2 No. 5 Reserved Set to "1". SW-A2 No. 6 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. SW-A2 No. 7 Communication error treatment in RTN sending mode (Reception ) Used to determine communication error treatment when RTN is sent by occurrence of a received image error in G3 reception.
