Setting Up the Serial Port(s)
80 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
z Virtual 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.
z Control 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.
z Modbus Gateway—The Modbus Gateway profile configures a serial port to act as a Modbus
Master Gateway or a Modbus Slave Gateway.
z Power 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.
z Remote 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.
z Remote 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.
z Custom 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 113 for more
information on the serial port profiles and their configuration parameters.
