In the normal operation mode (SW1-7 OFF), the switch
state is scanned immediately after the master reset has
done, and is set in the SRN controller. Master reset
must therefore be done when the transmission speed
setting is changed.
In the diagnostic mode, the transmission speed is set
each time, immediately before the execution of the SRN
basic test or the host terminal emulation.
SW2-6,7 Used to set the carrier off monitoring time.
