MT5634ZBA-USB User Guide
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 MT5634ZBA-USB 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.
1. Establish a data connection with a remote MT5634ZBA-USB modem.
2. Send three remote configuration escape characters followed by AT and the setup
password, and press ENTER. Example: %%%ATMTSMODEM<CR>. You have four
tries to enter the correct password before being disconnected. If the password is
correct, the remote modem responds with
OK
3. You can now send AT commands to configure the remote modem.
4. When you have finished configuring the remote modem, save the new configuration
by typing AT&W0<CR>, then type ATO<CR> 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). Because
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 modem
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 password,
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 remotely
configure the modem you must use the new setup password.
Note: You can only change the setup password locally; you cannot do it remotely.
Also, passwords are case sensitive. The next time you enter the password, it must
be in the same case as you set it up.
