Advantech B+B Smartworx, Compact Ethernet Serial Server – (1) Serial DB9 & TB, (1) 10/100 Ethernet RJ45

SKU: VESR901 Category:


The VESR901 Industrial Ethernet Serial Servers gives serial equipment the ability to connect to a Ethernet network. If it has a serial port, it can be monitored and controlled from anywhere on your Ethernet LAN or WAN. Keep 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.

The VESR92x Series also features an additional copper RJ45 port that allows you to connect another Ethernet device or PC work-station. This pass- through port functions much like an unmanaged switch. Heartbeat connectivity keeps the serial server online. If connectivity is lost, it attempts to reconnect every five seconds until connection is regained. A manual reboot is not needed when communications are restored.
