Note
The selection of the standard dedicated line profile not only depends on the required
transmission speed but also on the interface to be used, the RS-232 or the RS-485 interface.
Standard dedicated line profiles 8 to 14 are only suitable for use with the RS-232 interface. If
you require the RS-485 interface, the user-configurable dedicated line profile 15 must be set
and configured. Profile 15 can, however, also be used with the RS-232 interface.
Loudspeaker ON or OFF
The MD3 modem is equipped with a loudspeaker. The loudspeaker allows you to hear all the
signal tones during the connection phase and during data transmission. The loudspeaker
can be turned on for test purposes or for normal operation.
