Chapter 6: Using the Web Interface135Configuring the Serial PortYou can change the bit-rate of the serial port labeled CONSOLE /MODEM on the EMX device. The default bit-rate for both console andmodem operation is 115200 bps.The EMX supports the use of one of the following devices via the serialinterface: A computer or Raritan KVM product for console management. An analog modem for remote dial-in and access to the CLI. A GSM modem for sending out SMS messages to a cellular phone.Bit-rate adjustment may be necessary. Change the bit-rate beforeconnecting the supported device to the EMX through the serial port, orthere are communication problems.Note: The serial port bit-rate change is needed when the EMX works inconjunction with Raritan's Dominion LX KVM switch. The Dominion LXonly supports 19200 bps for communications over the serial interface.You can set diverse bit-rate settings for console and modem operations.Usually the EMX can detect the device type, and automatically apply thepreset bit-rate.To change the serial port baud rate settings:1. Choose Device Settings > Serial Port Settings. The Serial PortConfiguration dialog appears.2. In the "Connected device" field, select an appropriate option to forcethe serial port to enter the correct state.Options DescriptionAutomatic detection The EMX automatically detects the device type onthe serial port.Select this option unless your EMX cannot correctlydetect the connected device.Force console The port enters the local console state.Force analog modem The port enters the analog modem state.Force GSM modem The port enters the GSM modem state.3. In the Console Baud Rate field, select the baud rate intended forconsole management.Note: For a serial RS-232 or USB connection between a computerand the EMX, leave it at the default (115200 bps).4. In the Modem Baud Rate field, select the baud rate used for themodem connected to the EMX.
