Industrial USB to Serial RS232/422/485 Converters

Industrial USB to Serial RS232/422/485 converters operate over a wide temperature range to cope with harsh operating conditions. The ISO versions are 2.5KV electrically isolated to withstand unbalanced ground loops that arise in hazardous industrial environments. Both DIN-Rail and wall-mounting options are available.

The Industrial Plus supports flexible RS232/422/485 ports (three way operation). The port configuration is done by easy-to-use DIP switches, completely jumperless. With 4 and 8 serial ports the configuration is also possible by configuration software. The metal cases can be easy used for DIN-Rail mounting, the 4- and 8-port versions also fit in a 19″ rackmount.

Installation & Configuration
Installation NetCom Plus Manager automatically finds NetCom Plus devices in the local network.
UPnP With Network discovery enabled NetCom Plus servers announce their presence via UPnP making their IP visible.
Configuration via WEB-Browser, Driver Panels, NetCom Manager, serial console, Telnet console or SNMP

Firewall Virtual-COM mode works through firewalls
Firmware Update via WEB Browser

Password Protection for all available configuration options e.g. via WEB-Browser
Secure Server create openVPN™ tunnels, for encrypted transmission of all serial and
configuration data using high security SSL/TLS standards.
viaVPN Remote Access (option)
Connect via Internet
viaVPN technology provides easy and secure access to remotely installed
NetCom Plus servers for their configuration or for connecting their virtual COM
ports through Internet. With the viaVPN option the NetCom Plus servers are
no more limited to only work inside of a local network.
Security All communications use openVPN-tunnels encrypted by SSL/TLS and AES-
256 standards.
Firewall friendly No Reconfiguration of firewalls is required for viaVPN remote access.
