NOTE The particular alarm message chosen is the highest-priority alarm condition in effect when
dialing commences.
Connection and Configuration
The unit is shipped with a default configuration of DISABLED and 9600 bps.
Any changes to the default values can be made using the command line
interface. To change the settings, use the command line interface. Each of the
configuration items is stored in the configuration database. In addition, the
state of the connection is maintained so that recovery from a power failure will
re-initiate the connection.
Multidrop configuration (multiple units sharing a modem) is supported only by
the use of an external port-sharing device.
Modem Setup Procedures
A pair of Hayes-compatible “external” modems, 1200 bps or higher is required.
Configure each modem according to the following procedure. Note that not all
so-called smart modems are identical. Please check your modem user’s manual.
Configuring the Modem
1. To reset modem to its factory defaults (for most modems):
a. Connect the modem to a terminal using a standard EIA/TIA-232 modem
cable.
b. Wait one second then type +++ on the terminal. Pause one second again
and then type AT&F<RETURN>.
c. Cycle power on the modem.
2. Configure the modem to ignore DTR, by typing AT&D<RETURN>, or
selecting a DIP switch on some modems.
3. Configure the modem to ignore RTS, by typing AT&K0<RETURN> (Hayes
compatible modems), or AT&H0<RETURN> (US Robotics modems), or by
selecting a DIP switch on some modems.
