Data sheet:

Com-Server OEM Mini, 10/100BT

  • Com-Server plug-in module

Ethernet TCP/IP for embedded systems

Details: Com-Server plug-in module


  • Network connection to TCP/IP Ethernet:
    • 10/100BT
  • Serial connection to embedded system:
    • Serial TTL level
    • optional RS232, RS485, RS422
  • Options:
    • All signals to header connectors
    • Alternative Ethernet connectors: Coax (10Base2), AUI, 100BaseFX
    • Customized board formats
    • Customized board functions, e.g. redundancy switching
    • Suitable RS232, RS485, RS422 modules available
  • Hardware:
    • Dimensions: 71 x 96 mm (or customer-specific format)
    • EMC-proof design
  • Software:
    • Full control on all properties of the module, including network addressing both from the network and the embedded side.
    • Behavior of the plug-in modules identical with that of other W&T Com-Servers. Existing equipment that doesn’t allow for built-in modules can thus be easily upgraded with a network connection.

Options for software integration:
The options for integration range from simple COM port redirection to user-friendly drag&drop programming in Visual Basic style on the PC side. More advanced options allow for the full integration of the end user. All the while, it is never necessary to program within the module, as it is fully equipped with all you need, while still flexible and controllable according to your requirements. You therefore maintain full control over the properties of your hardware. Network and web access is now achievable with a minimum investment of time and money. Make our advantage yours!
