External modem adapter
If you need to connect a Contivity 1010, 1050, or 1100 to a modem, you can order
a null modem adapter from Nortel Networks. This adapter allows you to connect
the Contivity 1010/1050/1100 console cable (shipped with the gateway) to an
RS-232-C modem port.
To ensure correct dial-in and dial-out operation, configure the modem with the
settings "verbal result codes" and "display result codes." For more information,
see the modem documentation.
The cable adapter has a DB9 connector that connects to the serial cable and a
DB-25 connector that connects to the modem
314961-E Rev 00
provides the RJ-45-to-DB9 serial interface cable pinouts.
Caution: Use only the serial cable shipped with the Contivity 1010,
1050, or 1100 and this modem adapter to connect a modem to the
Contivity 1010, 1050, or 1100. Other cables and adapters may not
provide adequate shielding for EMI regulatory compliance.
