Isolated Industrial Ethernet serial servers
VESR321 Series
Take control of your serial devices with Vlinx
 VESR321 Isolated Industrial 
Ethernet Serial Servers.
Easy to use Vlinx
 Manager software puts access to your whole shop right 
on your desktop. Configure your serial devices, upgrade firmware and 
monitor activity from a single location. The data ports are isolated from one 
another and also from the power supply.
Multiple fiber optic options make integration into any existing network 
quick and easy. Choose from Multi-mode LC and Single-mode LC.
VESR321 series servers also feature an additional copper pass-through 
RJ45 port that functions like an unmanaged switch, allowing you to 
connect another Ethernet device or PC work-station. 
Heartbeat connectivity keeps the serial server on-line. If connectivity is lost 
it attempts to reconnect every five seconds until a connection is regained. A 
manual reboot is not required when communications 
are restored.
