B&B Vlinx VESR321 Series - Isolated Ethernet Serial Servers

RS-422/485, RS-232/422/485 and RS-232 to Ethernet

Introduction

VESR321 isolated servers connect serial devices (RS-232, RS-422 or RS-485) to Ethernet networks, enabling the serial device to become a node on the network. The serial ports can be accessed over a LAN/WAN using Direct IP Mode, Virtual COM Port, or Paired Mode connections.

  • Three-way Isolation
  • Ethernet Pass-through Port available
  • Ethernet Fiber Options
  • Heavy Industrial EN61000-6-2 rated
  • Wide Operating Temperature
