Esta pasarela serial/ethernet cuenta con 4 puertos seriales que pueden trabajar con los siguientes estándares de capa física: RS-232, RS-485, RS-422.

Las aplicaciones típicas son:

Encapsular tráfico de puerto serial en socket TCP/IP
Convertir protocolos Modbus RTU a Modbus TCP (y Viceversa)
El equipo incluye fuente de alimentación, un cable con conectores DB9 para RS-232 y cuatro adaptadores de DB9 a bornera.
