Com-Server Display Version, 4 serial ports

  • Com-Server Display Version, 4 serial ports

Due to a mistake by our component supplier the Com-Server 58004 is unfortunately no longer available. From a software point of view the most compatible replacement model could be the Com-Server Highspeed Office 58034. The following table summarizes the differences in key technical data.

Differences between the models:
Com-Server Display, 58004
Com-Server Highspeed Office, 58034
Serial port: 4 x RS232 to DB9/M 4 x RS232/422/485 selectable to DB9/M
Network: 10MBit/s BNC and RJ45 10/100BaseT RJ45
Displays: Display and LEDs LEDs
Configuration/management: Local and 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).
