B&B Vlinx VESR900 Series single- and dual-port serial device servers

Click2Contact

Vlinx VESR900 Series industrial ethernet serial servers allow users to monitor and control serial devices from any point on their ethernet LAN/WAN. The easy-to-use Vlinx Manager software provides remote access to device servers and serial ports directly from the user’s desktop computer or laptop. Configure devices, upgrade firmware and monitor activity using the Vlinx built-in web server.

The series includes single- and dual-port models with support for RS232 and RS422/485 protocols. Virtual com port drivers can be installed on workstations, allowing applications to access the remote com ports as if they were directly connected to a local com port. In Direct IP mode, serial data can be sent directly to the device server’s IP address. Paired mode is also available, allowing data to be sent directly from one device server to another via the network.

The device servers provide both DB9 serial connectors and screw terminal blocks for cable termination. The servers also feature an additional copper RJ45 port that allows the user to connect another ethernet device or PC workstation. This pass-through port functions like an unmanaged ethernet switch.

If the device server looses connectivity, a manual reboot is not needed to restore communications. The device server will attempt to reconnect every 5 s until the connection is re-established. This heartbeat connectivity signal ensures the series is always online.

The device servers are ultracompact, measuring only 17 x 11 x 4 cm. Optional DIN rail mounting brackets are available.
