Com-Server 19" version, 1 serial port

  • Com-Server 19" version, 1 serial port

Due to a mistake by our component supplier the Com-Server 58301 is unfortunately no longer available. From a software point of view the most compatible replacement model could be the Com-Server Highspeed OEM 19" 58331. The following table summarizes the differences in key technical data.

Differences between the models:
Com-Server BNC 19", 58301
Com-Server Highspeed OEM 19", 58331
Serial port: 1 x RS232 to DB9/M 1 x RS232/422/485 selectable to DB9/M
Network: 10MBit/s BNC and RJ45 10/100BaseT RJ45
Configuration/management: Telnet Telnet and Web-Based-Management

Background information:

The Com-Server provides everything you need for directly connecting a serial port to the computer network. All protocols are included (see text box and applications included with the product data sheets). In place of the standard existing RS232 port, various port modules can be used. The serial and network parameters are configured via Telnet, ARP/RARP.

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).
