Operating Modes

Driver mode VScom Driver for Windows NT 4.0, 2000, XP and 2003

Driver Mode creates virtual Com port.

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 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

Password access Every capabilities of configuration use the same password including SNMP V3

Secure communication OpenVPN" tunnel provides security on Ethernet and Wireless networks. The tunnel protects the configuration as well as all serial data. It is also usable across the Internet.

Strong encryption by AES up to 256 bit keys.

WEP Encryption with 64 and 128 bit for compatibility in simple installations

WPA Modern Wireless protection by WPA-PSK/TKIP
