Figure 5-49 Possible settings with the DIL switch accessible from above
Note
The MD4 modem adopts the settings at the DIL switch only when the 24 V DC power supply
is turned on. While the settings are being adopted, the MD4 indicates this by the four lower
LEDs lighting up in sequence. As soon as the LEDs start flashing sequence, the set function
has been adopted.
Settings for dialing mode
For dialing mode, a standard profile must be set. The setting is made with the 4-pin DIL
switch. Standard profiles 0 to 3 are default settings that enable the MD4 modem to be
operated without any programming using a terminal program if one of these standard profiles
matches the intended application. Each standard profile can also be freely configured by the
user and therefore requires programming by a terminal program before it can be put into
operation.
The procedure is as follows:
Turn of the power supply and set all four switches mentioned above to the required position.
When you turn on the power supply, the modem then adopts the selected setting.
Note
Standard profile 0 should be selected for connecting the MD4 to a TIM.
The following table lists the properties of the individual profiles and how to set them using the
switches mentioned above.
