Active Communication

Options for software integration:
The options for integration range from simple COM port redirection to user-friendly drag&drop programming in Visual Basic style on the PC side. More advanced options allow for the full integration of the end user. All the while it is never necessary to program within the module, as it is fully equipped with all you need, while still flexible and controllable according to your requirements. You therefore maintain full control over the properties of your hardware. Network and web access is now achievable with a minimum investment of time and money. Make our advantage yours! For more information, please refer to the overview of ad-hoc solutions for embedded systems.

COM Port Redirector
The W&T COM Port Redirector for Windows 9x/NT/2000/XP/2003 also gives serially operating Windows programs the ability to communicate over the network. Virtual COM ports are installed on the system which behave like standard COM ports with respect to the applications. Communication with the terminal device is now however over the network and a Com-Server (data sheet with download link).

• Network connection to TCP/IP Ethernet:
  • 10/100BT
• Serial connection to embedded system:
  • Serial bit rate up to 230.4 kbit/s
  • Serial TTL level
  • optional RS232, RS485, RS422
• Remotely configurable via Web Based Management
• Options:
  • All signals to header connectors
  • Customized board formats
  • Suitable RS232, RS485, RS422 modules available
• Hardware:
  • Dimensions: 71 x 96 mm (or customer-specific format)
  • EMC-proof design
• Software:
  • Full control on all properties of the module, including network addressing both from the network and the embedded side.
  • Behavior of the plug-in modules identical with that of other W&T Com-Servers. Existing equipment that doesn’t allow for built-in modules can thus be easily upgraded with a network connection.
• Conforms to standards both in office and industrial environments:
  • Increased noise immunity for industrial areas
  • Stricter noise emission for residential and commercial areas

Protocols:

• Serial port protocols:
  • XON/XOFF
  • Hardware handshake
  • SLIP
  • other protocols on request
  
  
• Protocols for direct network connection:
  • TCP/IP:
    Socket, FTP, Telnet per client and server
  • Auxiliary protocols:
    ARP, RARP, DHCP/BOOTP,PING, RIP, SNMP
    Inventory keeping, group management
  
  
• Protocols for paired Com-Server operation:
  (connect serial devices in pairs on the network)
  • Box-to-box mode TCP/IP
