Convertidor RS232 a RS485 bidireccional pasivo de grado industrial para comunicación de larga distancia entre dispositivos industriales (comerciales).
El circuito de E/S controla automáticamente el flujo de datos, lo que elimina la necesidad de una señal de protocolo de enlace, lo que garantiza que el programa escrito en modo semidúplex RS232 pueda ejecutarse en modo RS485 sin modificaciones.
El supresor de voltaje transitorio (TVS) incorporado admite protección contra sobretensiones de 600 W y protección estática de 15 KV, protegiendo eficazmente los dispositivos contra daños.
No se requiere alimentación externa, utiliza una "bomba de carga RS232" para que el convertidor funcione y puede recibir energía sin inicializar el puerto serie 232.
Adecuado para sistemas de control de acceso, equipos de vigilancia, equipos terminales, control industrial, adquisición de instrumentos digitales, microcontroladores, etc.
