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.  

Interfaces:

• 1 x serial standard interface
  • 9-pin SUB-D connector
• 1 x TTL interface
  • 12-pin male header with 2mm spacing

Management and connectivity:

• Tiny plug-in interfaces
• Interface
  • RS485/RS422

Standards & more

• Conforms to standards both in office and industrial environments:
  • High noise resistance for industrial environments
  • Low noise emission for residential and business areas
• 5 year guarantee
