5. Before handling the MultiModem, discharge static in your body by touching a piece of bare metal on
the chassis. Carefully remove the MultiModem from its antistatic bag, handling it only by the
mounting bracket and edges. Do not touch the gold-plated connectors along the bottom edge.
6. Look at the system’s main board to determine either PCI or Express connector. Place the
MultiModem directly above the expansion slot and gently, but firmly, push it into the connector until
the card’s retaining bracket is flush against the system chassis.
8. Fasten the retaining bracket to the system chassis with the screw saved in step 4.
9. Replace the system cover.

Chapter 3: Remote Configuration
Remote configuration is a network management tool that allows you to configure the MultiModem anywhere
in your network from one location. With password-protected remote configuration, you can issue AT
commands to a remote modem for maintenance or troubleshooting as if you were on site.
Basic Procedure
The following steps are valid regardless of whether the connection is established by the local or the remote
Multi-Tech modem.
Note: For this procedure, the remote computer must be running, and a communication program must be
ready for a data connection.
1. Establish a data connection with a remote MultiModem.
2. Send three remote configuration escape characters followed by AT and the setup password, and
press ENTER. Example: %%%ATMTSMODEM (all capital letters). You have four tries to enter the
correct password before being disconnected. If the password is correct, the remote modem responds
with OK.
3. Type AT commands to configure the remote modem.
4. When you have finished configuring the remote modem, save the new configuration by typing
AT&W0 and pressing ENTER.
5. Type ATO and press ENTER to exit remote configuration. You can now break the connection in the
normal way.
Setup
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who
has the User Guide knows the default setup password, you should change the password and possibly
also the remote configuration escape character. Record your changes for future use.
To Change the Setup Password
1. Open a data communications program such as HyperTerminal.
2. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and
then press ENTER. The password can include any keyboard character, and can be up to eight
characters long. The modem responds with OK.
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the
same case as you set it up.
3. The new password is saved automatically. You can now either enter more AT commands or exit
the data communications program. The next time you wish to set up the modem, you must use
the new password.

To Change the Remote Escape Character
To further improve security, you can change a remote modem’s remote configurationescape character
either locally or remotely. The remote configuration escape character is stored in register S9. The factory
default is 37, which is the ASCII code for the percent character (%). Setting S9 to 0 (zero) disables
remote configuration entirely.
CAUTION: If you set S9 to 0 (zero) remotely, you won’t be able to change it back remotely.
1. Establish a remote configuration link with the remote modem as described in “Basic Procedure.”
2. Type ATS9=n, where nis the ASCII code for the new remote configuration escape character,
and then press ENTER.
3. Save the new value by typing AT&W and pressing ENTER. Record for future use.
4. Type ATO and press ENTER to exit remote configuration.
