WE-2100T Series User’s Manual Selecting an Operation Mode

ATTENTION
Real COM drivers are installed and configured through the included Windows utility.
Real COM mode allows you to continue using your serial communications software to access
devices that are now attached to the WE-2100T module. On the host, the Real COM driver
automatically intercepts data sent to the COM port, packs it into a TCP/IP packet, and redirects it
to the network. At the other end of the connection, the WE-2100T accepts the Ethernet frame,
unpacks the TCP/IP packet, and sends the serial data to the appropriate device.
ATTENTION
In Real COM mode, several hosts can have simultaneous access control over the serial port on the
module. If necessary, you can limit access by using the Accessible IP settings. Please refer to
Chapter 9 for additional information on Accessible IP settings.
