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:
    • XP/Vista/7/8/8.1/10 incl. all 64-bit and Server Editions
    • NT4.0
    • 2000
    • 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 COM Port Redirector is available in three versions for Windows 95/98/ME, Windows NT/2000 as well as all newer Windows versions from XP and higher. It can be installed in just a few steps and without restarting 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 as usual, for example, the COM3 port, which however is now no longer local on the computer, but rather is located somewhere in the network.

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!

Companion is included in the standard installation of the W&T COM Port Redirector.


Virtual modem ports

(only COM Port Redirector Legacy, Art. No. 00102)

Comparable to Voice-over IP, W&T LAN modems are used wherever charged dial-up connections need to be replaced by the often already existing network infrastructure. Instead of the old modems, LAN modems are installed and then the dial-up number replaced by the destination IP address in the AT dial-up command... that’s it! If the software side is a Windows application, you can eliminate the hardware LAN modem and instead use a virtual modem-modem port on the COM Port Redirector.


Soft-Link between 2 computers

(only COM Port Redirector Legacy, Art. No. 00102)

Imagine you have 2 Windows applications that can only exchange their data serially, but the computers have no free COM port available. The Soft-Link function allows you to make virtual serial connections over the Intra- or Internet, without any hardware. Interested ?
