What to do if DeviceInstaller shows “No response from device!” message for Lantronix Network Hardware?
This message usually appears because the hardware address is incorrect, the IP address is invalid for your subnet, or the subnet mask is wrong. Double-check the parameters you've entered. Note that you cannot assign an IP address to a device server through a router.
Why can I ping but not Telnet to Lantronix Network Hardware on port 9999?
This could be due to an IP address conflict on your network, or you are not Telneting to port 9999. It is also possible that the Telnet configuration port (9999) is disabled in the device server security settings or a network device, like a router, is blocking port 9999. To resolve this, turn off the device server, then use the DOS prompt on your computer to enter the commands ARP -D X.X.X.X (where X.X.X.X is the device server's IP address) and PING X.X.X.X. If you get a response, there's a duplicate IP address on the network. If you don't get a response, use the serial port to verify that Telnet is not disabled.
How to fix Lantronix Network Hardware not communicating with serial device?
The most likely reason is the wrong serial settings were chosen. The serial settings for the serial device and the device server must match. The default serial settings for the device server are RS232, 9600 Baud, 8 Character Bits, No Parity, 1 Stop Bit, No Flow Control.
What to do if nothing happens when I press Enter after seeing “Press Enter to go into Setup Mode” on Lantronix Network Hardware?
This happens because you didn't press Enter quickly enough. You only have 5 seconds to press Enter before the connection is closed. Telnet to port 9999 again, but press Enter as soon as you see the message “Press Enter to go into Setup Mode.”
Why is my Lantronix Network Hardware not communicating with my device across the network?
If the serial port settings are correct, you might not be connecting to the correct socket of the device server. Check the cables and wiring. To check whether there is a socket connection to or from the device server, look at the Ready LED. If the Ready LED is blinking consistently, there is a good socket connection. If the Ready LED is solid green, the socket connection does not exist. Use the Connect Mode option C0 for making a connection to the device server from the network. Use Connect Mode option C1 or C5 for a connection to the network from the device server.
How to fix “The ARP entry addition failed: 5” error on Lantronix Network Hardware?
This message indicates that your currently logged-in user does not have the correct rights to use this command on this PC. To resolve this, have someone from your IT department log you in with sufficient rights.
What to do if Telnet connection fails after assigning IP via ARP method on Lantronix Network Hardware?
When you Telnet into port 1 on the device server, you are only assigning a temporary IP address. When you Telnet into port 9999 and do not press Enter quickly, the device server will reboot, causing it to lose the IP address. Telnet back into Port 1. Wait for it to fail, then Telnet to port 9999 again. Make sure you press Enter quickly.
Why do I get a “No Connection With CoBox” message when connecting to the Web-Manager in Lantronix Network Hardware?
Your computer is not able to connect to port 30718 (77FEh) on the device server. Make sure that port 30718 (77FEh) is not blocked with any router that you are using on the network. Also make sure that port 77FEh is not disabled within the Security settings of the device server.
Why Lantronix Network Hardware device server won't power up properly and LEDs are flashing?
