Keep it at maximum productivity without leaving your office. Even troubleshoot it from outside your LAN via the internet. The easy-to-use Vlinx™ Manager software puts access to your entire factory floor on your desk. Configure devices, upgrade firmware and monitor activity. Configuration changes can also be made using a web browser. Model VESR921 also features an additional copper RJ45 port that allows you to connect another Ethernet device or PC work-station.
