Introduction

Remote configuration is a network management tool that allows you to configure
modems anywhere in your network from one location. With password-protected
remote configuration, you can issue AT commands to a remote MT5634MSV mo-
dem 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.

1. Establish a data connection with a remote MT5634MSV modem.

2. Send three remote configuration escape characters followed by AT and the setup

password, and press ENTER. Example: %%%ATMTSMODEM. You have
four tries to enter the correct password before being disconnected. If the pass-
word is correct, the remote modem responds with

3. You can now send AT commands to configure the remote modem.

4. When you have finished configuring the remote modem, save the new configura-

tion by typing AT&W0, then type ATO to exit remote configuration.
You can then break the connection in the normal way.

CAUTION:

If you hang up while you are in remote configuration mode, it may

lock up the remote modem.

Setup

Multi-Tech modems are shipped with a default setup password (MTSMODEM). Be-
cause anyone who has an owner’s manual knows the default setup password, for
security you should change the password and possibly also the remote configuration
escape character.

Changing the Setup Password

1. Open a data communications program such as HyperTerminal.

2. In the terminal window, type AT#SMTSMODEM (or AT#Syyyyyy if you have

replaced the MTSMODEM password with yyyyyy) and press ENTER. The mo-
dem responds with OK if the setup password is correct, and ERROR if it is wrong.

3. To change the password, type AT#S=yyyyyy, where yyyyyy stands for the pass-

word, and press ENTER. The password can include any keyboard character, and
must be one to eight characters long. The modem responds with OK.

4. The new password is saved automatically. You can now either enter more AT

commands or exit the data communications program. The next time you remote-
ly configure the modem you must use the new setup password.
