The highly compact Com-Server Highspeed Isolated provides everything you need for directly connecting up to 3 serial interfaces to the computer network in industrial environments. All three interfaces are optically separated with a dielectric strength of 1 kV, both mutually and with respect to the supply voltage. In this way, breaks in operation due to potential differences, and problems occurring for example in the case of remote lightning strikes or when powerful rotary current motors start running, are counteracted from the very beginning.
All protocols are included (see box or applications after the product datasheets). The serial interfaces of the Com-Server can be switched between the standards RS232, RS422 and RS485. The serial and the network parameters are set via Telnet, ARP / RARP, SNMP or also via an Internet browser and web-based management.
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).
