User-configurable profile 7 for dialing mode
If none of the standard profiles 0 to 6 is suitable for the required application, profile 7 can be
configured by the user and stored in non-volatile memory. As default, the configurations of
profiles 7 and 0 are identical.
When configuring profile 7, you can use all the AT commands listed in Chapter 6 of the MD 3
description 6NH7811-0AA31 that can be ordered separately.
To configure profile 7, follow the steps below:
1. Turn off the power supply to the modem.
2. Set standard profit 7 on the modem (SW2 DIL switch).
3. Connect the modem to the PC over its RS-232 port.
4. Turn on the power supply to the modem.
5. Transfer the required AT commands to the MD 3 using the terminal program.
6. Store the profile in non-volatile memory.

User-configurable profile 15 for dedicated line mode
The user-configurable dedicated line profile 15 is intended mainly for applications in
dedicated line mode in which the RS-485 port of the MD 3 is used. Profile 15 can, of course,
also be configured so that it works in conjunction with the RS-232 port. This is useful, for
example, if the user requires a transmission rate that is not available with any of the standard
profiles 8 to 14.
When configuring profile 15, you can use all the AT commands listed in Chapter 6 of the MD
3 description 6NH7811-0AA31 that can be ordered separately.
The tables summarize the AT string for configuring profile 15 for dedicated line mode for use
with the RS-485 and RS-232 port.
