The LANUSB combines the Ethernet connectivity of the LANCNC with the USB interface of the USBCNC-INT.The Ethernet side of the LANUSB acts as an FTP server for file storage that in turn an operator can access at the control panel on a CNC. Connection to the FTP server can be done with standard software tools that are provided with most PC’s. No logon is required as the LANCNC FTP Server accepts anonymous logins. Special software is not required. The most popular of these are Explorer and Internet Explorer from Microsoft. Anyone on the network can drag and drop files to the CNC server where they can be transferred to machine memory or drip fed (DNC). Conversely, files residing in CNC memory can be sent to the data server where they can be accessed by anyone on the network. File information is stored on an SD card resident on the LANCNC. A 4 GB SD card is provided as standard. Other sizes may be substituted. In the event of a network outage, the SD card may be removed and inserted into a PC. Files can be added or stored at the PC and replaced in the LANCNC.The LANUSB employes a unique design to provide network lag protection. CNC controls can be extremely sensitive to the flow of data through the RS-232 port. Any disruption to this flow can create problems in the part being machined. To protect against this, the LANUSB always buffers the entire program at the machine. The LANUSB is a dedicated computer that responds immediately to changes in the data flow to and from the CNC. Since the programs are buffered or stored on the LANCNC, the LANUSB continues to run even if the network fails. If the network starts to lag or lose integrity, the LANUSB will continue to run in real time.The USB interface is as simple as loading a file from an office computer to any size USB flash drive. Plug the USB flash drive into the panel mount USB connector and the operator is ready to download or drip feed (DNC) to any CNC that uses G code files. Files on the CNC can be easily uploaded to a USB flash drive for storage.
