Network link speed
This field indicates the Ethernet physical link speed. “Auto” indicates
that the speed has automatically been assigned by the NETRS2321E
adapter. You can also specify 10Mbps or 100Mbps, depending on the
speed of the hub to which the adapter is connected.
DHCP client
This field will indicate either enabled or disabled status. Enable DHCP
if there is a DHCP server on your network, otherwise, leave this value
as disabled.
Socket Port of HTTP Setup
The socket port used to conduct the browser setup. Normally, HTTP
protocol uses TCP port 80 for communication. If the field is changed to
81, port 80 will be reserved as an Internet connection.
To enter the browser setup page, “http://x.x.x.x:81” should be entered
for port 81, and “http://x.x.x.x” for socket port 80, where x.x.x.x is the
NETRS2321E IP address.
Socket port of serial I/O (RS-232/422/485):
• Port number:
A socket port assigned to the serial port. This 16-bit
number ranges from 1 to 65535. Because the numbers
below 1000 are used for specific purposes (i.e. 80 is
for the http protocol), it is advisable to select a number
larger than 1000. Generally, the port number 4660 is
used for serial communication. However, you should
specify a different port number for each serial port.
• Socket type:
TCP Server:
TCP protocol, passive open, to be
connected from TCP clients.
TCP Client:
TCP protocol, active open, connect to the
TCP Server.
UDP:
UDP protocol, connectionless.
