SC300 Setup
Not all modems are suitable. If your modem does not operate correctly check the modem setup
string. Contact your Eaton dc product supplier or Eaton for further assistance. See Worldwide
Support on page 153.
► To enable modem communications
1 Connect to the SC300:
2 On web, go Interfaces > Physical Ports > Serial.
3 In DCTools, go to Communications > Physical Ports > Serial > Modem.
4 Click on + to expand Serial. Configure the following settings:
Enable Modem: Enabled
Modem Power Reset: Optional. If this is enabled, then the SC300 will attempt
to reset a non-operating modem by turning its power
supply off and on using digital output 2.
Modem Set Up String: The string sent to the modem on reset.
The modem AT command should not be included as it
is automatically sent. The Auto-Answer Rings
parameter is also sent, so it does not need to be
included here. For complete details of appropriate
commands, consult your modem documentation.
Modem Auto Answer Rings: Number of rings before an incoming call is answered.
Setting this parameter to zero disables incoming calls
(the modem can still be used for alarm reporting).

Worldwide Support on page 153.
► To enable SMS alarm messages

3 For each cellphone to receive SMS alarm messages set the Phone Number and other details as
required.
4 Type the required Prefix string if alarm messages are to be sent to an email address.
This requires a GSM-Email Gateway connected to the GSM network. Contact the GSM network
operator for details of the Prefix string required at the beginning of the SMS message.
Emails can also be sent via an IP network. See details on page 110.
