Advanced Settings
Ports that have been activated on your PC can generally be used without any further
configuration. There are, however, additional configuration options available through
the IP Extender Manager.
Port Modes
The interface converter converts serial port data to and from TCP/IP packets over
Ethernet. Each port exchanges TCP/IP packets on its own unique TCP port (called
the "Local Port" in the Properties dialog box). Each serial port on a device can be
configured independently to perform this conversion in one of four modes. To edit
the port mode settings, open your IP Extender Manager and click on the "Port 1" (or
whichever port you want to edit) tab. Choose from the following:
Windows Mode (Default mode)
This mode causes an NETRS232 serial port to operate as a virtual port on a
Windows 2000/XP PC. In this mode, the port accepts its serial port settings from
the application/operating system that is accessing it. This is the factory default
mode when the device is installed.
Applications: General serial port access from applications running on a PC.
Raw Mode - Server
This mode is used to establish a raw connection to the device. In this mode, the
device accepts those settings specified for the "local port" in the Port Settings
dialog box as its serial port settings. Operating as a server, the device opens the
serial portand buffers serial port data until a client (PC) retrieves it.
Applications: Remote monitoring, security systems.
Raw Mode - Client
This mode is used to establish a raw connection to the device. In this mode,
the device accepts the settings specified for the "local port" in the Port Settings
dialog box as its serial port settings. Operating as a client, the device directs that
port to wait for data from server (PC), then open the serial port and transmit
data. In this mode, the user specifies a target IP address and TCP port for
device to use.
Applications: Remote control.
RFC2217 Mode
This mode opens an NETRS232 port when a TCP connection is established to
the "local port. " Port settings are embedded in data stream in accordance with
RFC 2217.
Applications: Recommended for use over the Internet.
