Setting Up the Serial Port(s)

zVirtual Modem—The Virtual Modem (Vmodem) profile configures a serial port to simulate a modem. When the serial device connected to the IOLAN initiates a modem connection, the IOLAN starts up a TCP connection to another IOLAN configured with a Virtual Modem serial port or to a host running a TCP application.

zControl Signal I/O—The Control Signal I/O profile enables the use of the EIA-232 serial port signal pins to be used as assigned Digital Inputs or Digital Outputs.

zModbus Gateway—The Modbus Gateway profile configures a serial port to act as a Modbus Master Gateway or a Modbus Slave Gateway.

zPower Management—The Power Management profile configures a serial port to communicate with a Remote Power Switch’s (RPS) administration port. This allows network access to the RPS and permits access to statistics and control of the RPS’s power plugs.

zRemote Access (PPP)—The Remote Access (PPP) profile configures a serial port to allow a remote user to establish a PPP connection to the IOLAN’s serial port. This is typically used with a modem for dial-in or dial-out access to the network.

zRemote Access (SLIP)—The Remote Access (SLIP) profile configures a serial port to allow a remote user to establish a SLIP connection to the IOLAN’s serial port. This is typically used with a modem for dial-in or dial-out access to the network.

zCustom Application/Plugin—The Custom Application/Plugin profile configures a serial port to run a custom application or IOLAN plugin. After you download the custom application files and specify the application name and any parameters you want to pass to it, the IOLAN will execute the application when the serial port is started.

Each serial port profile contains all the parameters that are required to completely configure the serial port scenario represented by the profile.

To select a serial port profile in the DeviceManager, connect through the DeviceManager to the IOLAN you are configuring and select Serial, Serial Ports in the navigation pane. Highlight the serial port you want to configure and then click Edit.

When the default serial port profile Terminal displays, click the Change Profile button and select the appropriate profile for the serial port. See Chapter 7, Configuring Serial Ports on page 103 for more information on the serial port profiles and their configuration parameters.
