NetCom+ 811 is an industrial-strength network-based serial device server for connecting eight RS232 devices like CNC, PLC, weighting scale, scanner and others directly to a network running TCP/IP. The driver for Windows operating system installs Virtual Com Ports. The NetCom+ 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. With 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 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 an existing serial port. NetCom+ 811 can be configured over Driver Panels, WEB Browser, serial Port, Telnet, SNMP and serves as a transparent serial channel without platform and distance limitation. The NetCom+ 811 is based on a modern RISC processor. It is powered via DC adapter or optionally by Power-over-Ethernet (PoE 802.3af). Further option is networking by WLAN 802.11b/g/n.

VScom Driver for Windows up to 8.1, Server up to 2008 R2, both x86 and x64 Editions. The Driver creates a virtual Com port, using VScom NetCom protocol.
Raw data transfer over TCP/IP. Accepts multiple incoming connections.
Raw data transfer over TCP/IP. Connects to multiple hosts or devices waiting for incoming connections.
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
Connecting two NetCom serial ports used as virtual null modem cable.
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.
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
A Modem attached to a serial port provides Dial-In/-Out. This allows access to the serial ports without a dedicated Ethernet connection.
