First, check the IP Address of your PC.
To check the IP Address, use the Windows Command Prompt.
-
Select Start - All Programs - Accessories - Command Prompt.
-
When the Command Prompt is started, execute the ipconfig command.
Example of executing the ipconfig command

Check that the IP Address of the PC is a proper address for communicating with the IP Address of SD-300/SD-310AN.
If the PC and SD-300/SD-310AN are in the same network segment but use a
different network number in their addresses, you need to
change either the address of the PC or SD-300/SD-310AN. Also, if
there is a router between the PC and SD-300/SD-310AN, check that the default gateway address is properly configured.

First, turn off SD-300/SD-310AN and open the Windows Command Prompt.
Ping the IP address of SD-300/SD-310AN.
-
Select Start - All Programs - Accessories - Command Prompt.
-
When the Command Prompt appears, execute the ping command.
Example of executing the ping command when the IP address of SD-300/SD-310AN is 192.168.20.20

If there is a reply while SD-300/SD-310AN is turned off, it means
there is
another network device using the same IP address as SD-300/SD-310AN. In
such
a case, change the IP address of either SD-300/SD-310AN
or the other network device.

I cannot communicate with a serial device.
If you cannot communicate with the serial device connected to
SD-300/SD-310AN, you need to check the communication settings on SD-300/SD-310AN
and the serial communication software.

When you are using SX Virtual Link for Serial Device
Server to communicate with a serial device, the serial communication
settings may differ between the serial device and serial communication
software. If the serial communication settings are different between
them, you may not be able to communicate with the serial device. Also,
output serial data may not be transferred correctly.
Check the settings on the serial communication software and match
it
with those used in the serial device. For details on how to change the
settings on your serial communication software, refer to the operation
manual that came with it.

If you are using Ecable Mode or Raw TCP Connection Mode to communicate with a serial device, the serial
communication
settings may differ between SD-300/SD-310AN and the serial device. If the
serial communication settings
are different between them, you may not be able to communicate with the
serial device. Also, output serial data may not be transferred
correctly.
You can change the serial communication settings of SD-300/SD-310AN from
the Web page. For details on how to change the settings on the Web
page,
refer to Configure Serial Port Settingsor Configuration
Item List - Serial
Port Configuration.

In Ecable
Mode, two SD-300/SD-310AN's must be configured with the proper IP addresses
to communicate with each other, and the same TCP port number should be
used for both. If these
settings are different between them, serial communication may
fail
due to a network connection not being established.
For detailed settings to use SD-300/SD-310AN in Ecable Mode, refer
to Ecable Mode
(Link to the Registered Device) - 2. Before
You Begin.

Solution

In Raw TCP Connection
Mode, SD-300/SD-310AN and the application program should be configured with
the same TCP port number. If this
setting is different between them, serial communication may
fail due to a network connection not being established.
For detailed settings to use SD-300/SD-310AN in Raw TCP Connection
Mode, refer
to Raw
TCP Connection Mode (Link to Serial Device Using TCP Raw Port) - 2. Before You Begin.

SD-310AN turns on in a wireless LAN mode although it is connected to a wired LAN using a network cable.
Solution
|
Extend the amount of time to recognize a wired LAN so that SD-310AN can turn on in a wired LAN mode.
The instructions below provide an example of how to set "5 sec" for the amount of time to recognize a wired LAN.
|
Access the SD-310AN Web page and click WEB console from the left menu.
Enter the SET NW STARTDELAY 5 to the field and click Enter.

|
|
Enter SAVE to the field and click Enter.
To check the setting, enter SHOW NW STARTDELAY to the field and click Enter.
The current setting is displayed.
