Compact Ethernet serial servers
The Vlinx VESP211 series of Ethernet serial servers from B+B Electronics Manufacturing Co. Inc. allow serial devices to become nodes on the network and are easy to network-enable because of a compact frame.
B&B Electronics Manufacturing Co., Inc. expanded its family of Ethernet serial servers with the Vlinx VESP211 series of small form factor serial servers. VESP211 Serial Servers connect RS-232, RS-422 or RS-485 serial devices to Ethernet networks, allowing the serial devices to become nodes on the network. With a footprint of only 5.1 x 7.6 x 2.5 cm, these compact servers make it easy to network-enable any serial device, even in tight installation spaces.
Vlinx VESP211 series servers are designed, tested and proven rugged enough for heavy industrial, 61000-6-2, EMC Level 3 harsh environments. They feature a wide (-40 C to 80 C) operating temperature, a barrel connector, the ability to use 10 to 30 V dc voltage input, and an IP30-rated metal enclosure that is panel (standard) or DIN-rail mountable (with optional adapter). The servers are shipped with a 12 V dc power supply.
Three designs are available. Model VESP211 supports RS-232/422/485 (MEI) with a DB9M serial port and RJ45 Ethernet port. Model VESP211-232 supports RS-232 with a DB9M serial port and RJ45 Ethernet port. Model VESP211-485 supports RS-422/485 with a removable terminal block and RJ45 Ethernet port.
