About VESR321 Family Serial Servers
VESR321 family serial servers connect serial devices (RS-232, RS-422 or RS-485) to Ethernet
networks, allowing 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.
VESR321 family serial servers feature 10BaseT or 100BaseTX copper network media and
several fiber optic media options, depending on the model. VESR321 family serial servers feature
an additional copper Ethernet pass-through port. VESR321 family serial servers are built for use
in industrial environments, featuring an IP30 approved slim line DIN rail mountable case. They
operate over a range of DC power supply voltages and feature pluggable terminal block and
threaded barrel power connectors.
VESR321 Family Serial Server Model Numbering
