NetCom 411 PRO is an industrial-strength network-based serial device server for connecting four RS232 devices like CNC, PLC, weighting scale, scanner and other devices directly to a network running TCP/IP.

NetCom 411 PRO V2 provides communication secured by SSL and AES-256 bit keys. This is implemented by openVPN tunnel software, which is Open Source and royalty-free for Server and Client software. Whith openVPN enabled the whole communication whith the NetCom runs through the secure tunnel. All data is automatically secured without implementing SSL into customers applications. SSL also protects the configuration and access to the attached serial devices.
In contrast to static key encryption the SSL function identifies each communication using unique certificates, so it is easy to allow or deny access per user. Further each serial port can control a modem for Dial-In and -Out via PPP.

In addition to allowing serial devices to get networked, any host (PC Server or Workstation) without network access can also access remote serial devices via adding NetCom devices to the existing serial ports.

NetCom 411 PRO can be configured over Driver Panels, WEB Browser, serial Port, Telnet, SNMP and serves as a transparent serial channel without platform and distance limitation.

Operating Modes
  Driver Mode
VScom Driver for Windows NT 4.0, 2000 up to 7, Server 2000 up to 2008 R2, both x86 and x64 Editions.
The Driver creates a virtual Com port, using Vscom NetCom protocol.
  TCP Raw Server
Raw data transfer over TCP/IP. Accepts multiple incoming connections.
  TCP Raw Client
Raw data transfer over TCP/IP. Connects to multiple hosts or devices waiting for incoming connections.
  TCP Advanced
  Settings
Special settings for user-defined modes.
  UDP Mode
Raw data transfer by UDP. The NetCom is client and server at the same time. Timeout functionality, maximum packet size and a configurable trigger string define the packets of incoming data to send over UDP
  Null Modem Tunnel
Connecting two NetCom used as virtual null modem cable.
  IP Modem
The serial port emulates a standard modem. Operates by AT-commands, and dials to IP-Addresses instead of phone numbers.
Windows "INF"-Driver provided for installation.
  Print Server
The NetCom accepts print jobs, and spools them to the attached serial printer. Operates as of RFC1197, similar to the line printer daemon in Unix-systems.
  PPP Net
A Modem attached to a serial port provides Dial-In/-Out. This allows access to the serial ports without a dedicated Ethernet connection.

Special Features
  Installation
Configuration utility automatically finds NetCom devices in the network
  Operating Mode
Automatic mode switching between Driver and TCP RAW mode. With TCP Advanced settings it is possible to configure the NetCom for using it in multiple modes, so it decides automatically which mode should be used.
  PPP Access
Dial-In to a modem attached to a serial port using Point to Point Protocol. TCP/IP is transported over the serial line, allowing access to configuration and the serial ports, even without Ethernet. A Dial-Out option is also provided.
  Configuration
Configuration over Driver Panels, NetCom Manager, WEB Browser, serial console, Telnet, SNMP.
  SNMP
Special VScom MIB included
  DNS
Domain Name Server support
  Firewall
Special precautions for Firewall environments
  Firmware
Firmware update over WEB Browser, Telnet, ComPort
  LEDs
LEDs for Power, serial Tx, Rx, Ethernet Link, Speed
