NetCom 123 WLAN 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.

This network may be based on 10/100Mbps Ethernet or Wireless LAN as of IEEE 802.11b/g.

NetCom 123 WLAN provides completely secured communication for configuration and to the attached serial device, this is implemented by openVPN tunnel software.

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 123 WLAN 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.

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.
  Configuration
Configuration over Driver Panels, NetCom Manager, WEB Browser, serial console, Telnet, SNMP.
  SNMP
Special VScom MIB included
  ART
Automatic Receive Transmit control for RS485
  DNS
