NetCom 423 WLAN is an industrial-strength network-based serial device server for connecting four 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 423 WLAN provides completely secured communication for configuration and to the attached serial device, this is implemented by openVPN tunnel software. Further a 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 device via adding NetCom devices to the existing serial port.
NetCom 423 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.
Keywords: Serial to Ethernet / WLAN converter, RS232, Device Server, Serial Port Server, RS485/RS422, RS232 zu Ethernet LAN Adapter, TCP/IP, Com Port Redirector, IEEE 802.11b/g
A Serial Device Server for TCP/IP on Ethernet/WLAN and Internet, RS232/422/485 as Com Ports in Windows. Modbus was tested by users.

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 and WLAN 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 and WLAN. 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 |
ART |
Automatic Receive Transmit control for RS485
|
DNS |
Domain Name Server support
