Installation for the NETRS2321POE involves software installation, as well as the setup of a virtual serial port using the software.
To install the software, complete the following:
Once the software is extracted, it will have to be run to first configure the device. To do this, complete the following:
The software should locate the NETRS2321POE. If it is required to change the IP address of the device, perform steps 6-9. If not, proceed to step 10.
Note: Ensure that the IP address given matches your network. If the device is connected directly to your PC, disconnect it and then connect it to your network. Ensure that you can still see the device by refreshing the Ethernet Manager.
Note: By default, there is no password required to log in.
Note: The Socket port of serial I/O number is needed for mapping the COM port to the PC, so this should be noted.
After the device is configured, a different piece of software will need to be run to create the virtual COM port. To do this, complete the following:
Note: The default values can be used, or the COM port can be changed if a specific one is needed.
In order for the serial device and your computer to communicate to each other, they both need to be on the same physical network and the same subnet.
To connect your serial device and your computer to the same physical network, plug both devices into the same router.
Typically, in order for devices to be on the same subnet, the first three numbers of the IP address must match. The fourth number of the IP address must be different, as two devices cannot have the same IP address. For example, if your computer’s IP address is 192.168.0.1, then the subnet is 192.168.0.XXX. You can replace the XXX with any number, as long as it is not currently in use by another device.
To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:
Note: To open a telnet session on the COM port, you need a telnet client like PuTTY or Hyper Terminal. Windows XP comes with Hyper Terminal.
If the loopback test fails, make sure that the serial cable or gender changer that you are using works and that the adapter is in the correct port.
You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session. When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is. Close the window for the port that you just tested to speed up the testing of the remaining serial ports.
This device's default static IP address is 192.168.1.254.
Press the Restore Default button on the device. This will immediately restore the unit to its default settings.
Du bör inte uppgradera enhetens inbyggda programvara om du inte har några problem med enhetens funktioner. Du behöver bara uppgradera om du har problem med enheten och är säker på att problemet är den inbyggda programvaran. Du kan bekräfta detta genom att läsa igenom den medföljande dokumentationen eller kontakta vår tekniska avdelning. Felaktig uppgradering av inbyggd programvara kan resultera i minskade prestanda så vi rekommenderar att du kontaktar StarTech.com först.
To troubleshoot this issue, you can try the following:
Before you begin, make sure that the serial device is on the same network and subnet. For more information, see this FAQ: http://www.startech.com/faq/serial_ip_networks_and_subnets. If the device starts with an IP address that is not on your subnet, change your IP address to match the subnet being used before you continue.
Ping the serial device
If the serial device and your computer are on the same network and subnet, try pinging the device.
To ping the device using a computer that is running a version of Windows XP, do the following:
To ping the device using a computer that is running a version of Windows Vista or Windows 7, do the following:
To ping the device using a computer that is running a version of Windows 8, do the following:
To ping the device using a computer that is running a version of Mac OS, do the following:
If you receive replies from the IP address, then you can see the device on the network and the issue is with something else.
Connect the serial device directly to the computer
To connect the serial device directly to the computer that you are troubleshooting with, complete the following:
Note: The second computer will need to be on the same network and subnet as the serial over IP device.
If you still cannot ping the device, contact support.
Make sure that you are working in a secure environment
If you still cannot connect to the device's web interface or by using the included software, contact support.
If you can access the web interface or connect using the included software, one at a time turn on your firewalls, antivirus programs, and security programs. Each time that you turn on software and cannot connect to the web interface or by using the included software, add an exception for the serial device to what you last re-enabled.
One of the most common applications of a network serial device is to use it to make a standard serial device accessible on a network. To do this, you need to connect a standard serial device to the DB-9 port on the network serial device. Next you need to connect the network serial device to a TCP/IP network using an Ethernet connection, and then install software on a client machine in order to access the network serial device. The software on the client machine communicates with the network serial device and creates (maps) a virtual COM port on your computer system. The virtual COM port is identical to a physical COM port and can be used in the same way.
You can use two network serial devices to extend a serial connection over a TCP/IP network. To do this, you need to configure one serial device as a client and the other as a server. The client and server are configured to transmit and receive data to their respective IP addresses and TCP ports. The serial settings must match for all connected serial devices, including the UART on both units. Depending on the serial device that you are using, you can use the provided software or the web interface to set the configurations.
You can use a network serial device to translate UDP data to a standard serial connection. The serial device is configured to listen for UDP traffic from specific IP addresses and ports, and will asynchronously transmit the data out of the serial port on the device. To do this, you need to configure UART on the network serial device to match the specifications of the serial receiver.
