NetCom 823RM 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 823RM 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 823RM 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.
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.
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
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
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 WPA2-AES, WPA-PSK/TKIP
