8.3Rear Port Configuration

This section provides information on setting up and configuring the rear port modem device (or a direct null modem serial cable connection) with the CXC to provide inbound web server support and/or outbound e-mail alarm support and/or SNMP trap dial-out support. To save changes, refer to Section 4.9.

The Alpha Cordex Controller (CXC, Alpha P/N 018-557-20 or 018-587-20) supports connection to one of the following:

Alpha-supplied internal modem daughterboard module (via rear RJ-11 jack), or

External AT-class V.34 or V.90 modem (via rear RS-232 serial port with DB-9 connector), or

Null modem direct cable connection (either front or rear RS-232 serial port) to a computer running Windows 2000.

8.3.1Internal Modem Support

The V.90 internal modem (Alpha P/N #707-329-20) module requires the CXC to be supplied with List Option 101 (modem module supporting global usage); which includes the List Option 95 Communications Board assembly.

8.3.2External Modem Support

The CXC also supports the use of a standard external AT-class V.34 or V.90 modem (e.g. US Robotics Sportster 33.6 or similar). The external modem must be connected by a standard DB-9 straight through serial cable to the rear RS-232 serial port (requires the CXC to be supplied with the List Option 95 Communications Board assembly).
