NETRS232 Advanced Features
This document describes the advanced configuration features of the NETRS232. It covers:
1. NETRS232 port modes
2. Virtual port (driver) settings
3. Virtual port (driver) bindings
4. Virtual port COM number assignment
1. NETRS232 port modes
The NETRS232 converts serial port data to and from TCP/IP packets over Ethernet. Each NETRS232 port exchanges
TCP/IP packets on its own unique TCP port (called the "Local Port" in the Properties dialog box). Each serial port on an
NETRS232 device can be configured independently to perform this conversion in one of eight modes:
Driver Mode (Default mode)
This mode enables the physical port of a NETRS232 to communicate directly with the serial port API of a supported
operating system as a local COM port. In this mode, authorized users can set bits per second, data bits, parity, stop bits,
and flow control port-by-port, or the port will accept its serial port settings from the application/operating system that
is accessing it. Driver mode is the factory default mode when a NETRS232 is installed.
When installed on a LAN, a NETRS232 in Driver Mode has all the functionality of an internally installed serial port.
When installed on a WAN or the Internet, the serial port of a NETRS232 gains enormous flexibility and power. To use a
NETRS232 port on a remote network:
1. configure the IP address and TCP port of the WAN connection in the IP-Extender Manager to match the gateway IP
address of the remote network,
2. map the IP address and TCP port of the remote gateway to the IP address of the NETRS232, and
3. configure the NETRS232 itself for Driver Mode.
Applications: General serial port access from applications running on a PC.
