Active Communication

Simply route your serial COM port into the network - also on 64-bit Windows systems -

• UP to 255 COM ports per computer
• Automatic setting of transmission parameters on the Com-Server
• Easy to use configuration applet in the control panel
• Supported Windows environments:
  • NT4.0
  • 2000
  • XP/2003/Vista/7 incl. 64-bit and Server-Editions
  • Win 9x/MI (Art. No. 00101)
• Automatic inventorying of Com-Servers
• Supports dynamic IP addresses in the Internet
  • Full TCP communication
  • DNS name resolution

Whether in measuring, automation or building technology, the number of serially communicating devices with their associated control tools in the field is enormous. The disadvantage when connecting these devices to the PC is on one hand the relatively short permissible distances and the cumbersome cable installation. In addition, modern PCs hardly ever still offer serial COM ports, but rather are equipped only with USB and Ethernet ports. The W&T COM Port Redirector provides an elegant solution to this dilemma. It offers for Windows up to 255 virtual COM ports whose devices are distributed in the TCP/IP network to Com-Servers - worldwide if needed. Existing serial software, which may have been in use for many years, becomes network-capable without changing a single line of code. The beneficial side-benefit of this solution is simultaneous galvanic isolation between computer and the respective terminal device.

The W&T COM Port Redirector is available for the current Windows versions NT/2000/XP/2003/Vista/7 incl. the 64-bit and server versions. Installation and configuration can be accomplished in just a few steps and without rebooting the computer: Install driver, link virtual COM to the IP address or URL and connect the serial device with the Com-Server to the network... that’s it! The application opens up as usual, e.g. the COM3 port, which is however no longer local on the computer, but rather is located somewhere in the network.

System requirements

• Operativsystem Windows NT/2000/XP/2003/Vista/7 incl. 64-bit and Server-Editions
• Network card (Ethernet) and TCP/IP protocol

When sending serial protocols, such as Modbus, ensure that their timing permits network operation with the mandatory latency times.

Companion-Tool for variable assignment of the COM ports

Although up to 255 COM ports are supported on Windows systems, many programs are static in operation and provide the user, regardless of the number of COM ports actually existing in the system, with only 9 or even 4 COM ports. By using the Companion Tool you can still connect a virtually unlimited number of terminal devices to such programs. Before starting the application simply drag 'n drop the IP address of the Com-Server to the desired COM port. That's it!
