Overview
| VS 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.
VS NetCom 123 WLAN provides completely secured communication for configuration and to the attached serial device.
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, XP and 2003, Vista
Driver Mode creates virtual Com port. |
TCP Raw Server | Raw data transfer over TCP/IP. Accepts multiple incoming connections. |
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. |
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 automaticly 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 automaticly 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 | Domain Name Server support |
Serial interface | Serial Interface configurable with DIP switch and by software |
Firewall | Special precautions for Firewall environments |
Firmware | Firmware update over WEB Browser, Telnet, ComPort |
LEDs | LEDs for Power, serial Tx, Rx, Ethernet Link, Speed, WLAN |
|
Security
