Interface Modules

for serial PC cards and Com-servers using 10/100BT

  • Interface module 18813

Freely selectable serial interface

W&T interface modules equip devices having only a serial TTL interface with almost any desired standard interface type. In addition the modules allow you to adapt the interface types of many W&T devices over a wide range. The modification is done by simply replacing the standard interface modules with modules of the desired interface type.
