NetCom 113 PRO V2 is an industrial-strength network-based serial device server for connecting one RS232/422/485 device like CNC, PLC, weighting scale, scanner and other devices directly to a network running TCP/IP.
The NetCom 113 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.
In addition to allowing serial devices to get networked, any host (PC Server or Workstation) without network access can also access remote serial device via adding NetCom devices to the existing serial port.
NetCom 113 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.

You might ask: “Why buy a book when I can Google a command?” Here is why the humble remains a superior learning tool:
Over the following weekends, Mira worked through the book like a novel. Each chapter revealed a hidden architecture of thought:
Pick one book from the list above, buy it (or borrow it from your local library’s digital collection), and open AutoCAD. The first line you draw today could be the first line of your masterpiece tomorrow. autocad book
The studio in Portland still stands today, its clerestory windows catching the morning light at exactly 15 degrees. And somewhere in Mira’s office, the coffee-stained book remains open to Chapter 4, waiting for the next person who needs to learn that every line begins with a single, well-placed point.
But the most valuable part wasn’t the commands. It was the —short, italicized stories from real projects. One described how a civil engineer once used overlapping viewports to reveal a clash between a HVAC duct and a load-bearing column before concrete was poured, saving $40,000. Another told of a young designer who forgot to purge unused layers; the file bloated to 300 MB and crashed the office server. You might ask: “Why buy a book when I can Google a command
If you have never drawn a line in CAD software, start here. This focuses on the 80% of commands you will use 100% of the time (Line, Circle, Trim, Extend, Offset, and Hatch).
This is not a tutorial; it is a collection of workflows. This niche assumes you already know how to draw but want to stop wasting time. The studio in Portland still stands today, its

| 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. |

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. |
