Before making remote configuration, make sure that the route between the
computer and the switch is reachable.
Before making a local configuration, make sure that the IP address of the
computer and the serial server are on the same subnet.
Note:
When the serial server is first configured. If it is configured locally, make sure the current
computer network segment is 1.
For example, suppose that the IP address of the computer is 192.168.5.60, need to
change the IP address of the network segment "5" to "1"
Operation steps
The steps are as follows:
Step 1 Open “Control panel > Network connection > Local area connection > Properties >
Internet protocol version (TCP/IPv4) Properties”.
Step 2 Change the "5" selected by the red frame in the figure to "1".
Step 3 Click "OK".
Step 4 End.

enter the error 3 times in succession, the browser will display "Access denied" to deny
access to the information. Please refresh the page and try again.
Step 5 Click “OK”.
Step 6 End.
After successful login, you can configure the relevant parameters and information of
the WEB interface as needed.

IP Report IP Report configuration column.
Note：
When the serial server adopts the "automatic IP address", it
reports the IP address of the user by intermittently, so that the user
knows the new IP address of the serial server in time.
Sever Address The server that receives the IP address report.
Sever Port The port that sends the IP address report.
Repeat Time The sending frequency of IP report.
When the DHCP server assigns a new IP address to the serial server, the host needs to
detect the new IP address of the serial server when the serial server is in a network
environment that dynamically assigns an IP address. When the dynamic IP address
changes, the serial server reports its own IP address to the user by intermittently, so that the
user knows the new IP address of the serial server in time.

Delimiter If the packet length or forced transmission time is 0 and the
number of delimited characters is greater than 0, the system
will receive the serial data and perform delimiter detection.
Whenever a matching delimited character (or combination
of characters) is received, the system immediately sends all
the cached data to the serial port over the network.
Character Handing Select the character handling method. The options are:
Retain: The system sends the received delimited
characters along with other data over the network.
Delete: The matching delimited character (or character
combination) will be deleted and the system will only
transfer data other than delimiters.
Transmit time If the forced transmission time is greater than 0, the system
sends the serial data received within the specified time
through a packet, in the range of 0 to 65535 ms. When the
transfer time is 0, it means
that the data transmission
interval is not restricted.
