NVT enable (for the remote serial port devices).TEA authorisation enable (useful for the security reasons).Define IP filter range (useful for the security reasons).Check and assign main network parameters (IP address, IP mask ans Gateway).List of all devices on the network segment (MAC list).Search for the devices over UDP broadcast.In this window you can assign the IP address to compatible devices ( PortBox, PortStore, PortStore2, I/O Controller, Charon 1 module, Poseidon etc.) Parameters : This tab is to be used with HW-group devices only. The Hercules SETUP is compatible with our free Virtual Serial Port, you can debug applications connected to remote serial port using Windows 2000 or higher. Test mode (TCP/IP terminal with TEA authorization support and NVT (Network virtual Terminal) parser for remote I/O pins control.UDP Config utility (IP, Port, MASK, GW setting).TCP/IP Client terminal (similar to 'Telnet').Serial port terminal (COM5 and higher support).In this case, the error appeared on a Linux when trying to upload code due to the drivers not being installed and the root permissions.Hercules is great utility if you are working with the serial and Ethernet devices & interfaces.

language:bashĪvrdude: ser_open(): can't open device '/dev/ttyUSB0': No such file or directory You may receive an avrdude: ser_open(): can't open device error similar to the output shown below. If you installed the drivers for the CH340 on your computer but have issues connecting via serial terminal or uploading code using the Arduino IDE, there may be an issue with your user settings preventing you from using the CH340. COM Port Not Available Windows, Mac, and Linux Users seem to be able to eventually get the board recognized by a combination of giving the computer time to finish the install ( close to 20 min), plugging the board back in multiple times, reinstalling the drivers, and/or resetting the computer multiple times ( repeat both steps). Others have had issues where the installation process hangs.īased on the customer experiences, this might be specific to the manufacturer and are usually isolated cases. However, the board cannot be accessed on the Arduino IDE. We have had a few reports on Windows 10 where the driver will automatically install and the board will show up under a new COM port as USB-Serial CH340, but with a different device name.
