Settings for a standard dialing profile
Apart from the default setting for the dial-up mode, switches SW2.2, SW2.3 and SW2.4 can
be used to select one of the 8 standard dialing profiles. Standard dialing profiles 0 to 6 are
default settings that enable the MD3 modem to be operated without any programming using
a terminal program if one of these profiles matches the intended application. Standard
dialing profile 7 can be freely configured by the user and therefore requires programming by
a terminal program before it can be put into operation (for details see section
configurable profiles
The procedure is as follows:
Turn of the power supply and set the four switches SW2.1 to SW2.4 to the required position.
When you turn on the power supply, the modem then adopts the selected standard dialing
profile.
The following table lists the properties of the individual dialing profiles and how to set them
using the switches mentioned above.
