Compliance and Warranty

This TAA-compliant device is manufactured in the United States and meets RoHS environmental standards. Backed by a comprehensive 1-year limited warranty, ensuring reliable performance for your industrial communication needs.

El convertidor BLACK BOX® Universal RS-232 a RS-422/485 con aislamiento óptico aísla y convierte señales RS-232 en señales RS-422/RS-485 y viceversa. A diferencia de otros convertidores, no se requiere software externo para controlar el flujo de datos. La entrada RS-232 está cableada para DCE a través de un conector DB9 hembra, y las señales RS-422/RS-485 se interfazan a través de un bloque de terminales extraíble. Para suministrar energía externa al bloque de terminales, necesita nuestra Fuente de Alimentación de Montaje en Pared de 120-VAC/12-VDC (PS1003). Para RS-232, la conexión requiere RD, TD y Tierra de Señal. En modo RS-422, el controlador está siempre habilitado para comunicaciones de doble vía. Se requiere un par trenzado para transmitir, y también se requiere un par trenzado para recibir. También se necesita un cable de referencia a tierra. Configuración de interruptores: Interruptor 1: RS-422; Interruptor 2: Eco Activado; Interruptores 3 y 4: 4 Hilos. En ambos modos RS-485, el controlador RS-485 se habilita automáticamente durante cada estado de espacio por la presencia de una señal RS-232. Cuando los datos RS-232 están en un estado de marca o inactivo, el controlador RS-485 se desactiva y las líneas de datos RS-485 se mantienen en un estado de marca gracias al sesgo proporcionado por una resistencia de 4.7 ohmios; el valor de esta resistencia puede necesitar ser cambiado, dependiendo de la terminación que utilice. Para conectarse a varios dispositivos RS-485 con un cable mínimo, seleccione el modo RS-485 de 2 hilos y medio dúplex de la unidad. Cuando se solicitan datos, el dispositivo dirigido transmite y luego vuelve al estado de recepción. Configuración de interruptores para este modo: Interruptor 1: RS-485; Interruptor 2: Eco Desactivado; Interruptores 3 y 4: 2 Hilos. Para circuitos de maestro/esclavo de 4 hilos, seleccione el modo RS-485 de 4 hilos y dúplex completo de la unidad. En este modo, los dispositivos dirigidos pueden recibir datos mientras transmiten datos de una solicitud anterior. Cuando se utiliza como maestro en un sistema de un solo maestro, el Interruptor 1 puede seleccionarse porque la unidad es el único transmisor en el sistema. Cuando se utiliza como un esclavo RS-485, el dispositivo RS-232 debe proporcionar direccionabilidad. El sesgo en un sistema maestro/esclavo es proporcionado por el esclavo de línea final. Configuración de interruptores para este modo: Interruptor 1: RS-485; Interruptor 2: Eco Activado; Interruptores 3 y 4: 4 Hilos.

FAQ
The Black Box Universal RS-232 to RS-422/485 Converter features 2000-VAC isolation, selectable RS-422 operation, RS-485 support for both 2-wire half-duplex and 4-wire full-duplex modes, and automatic RS-485 driver control. It doesn't require external software for data flow control and comes with a DB9 female connector for RS-232 input and a removable terminal block for RS-422/RS-485 signals.
The converter has compact dimensions measuring 1.7 inches in height, 0.9 inches in width, and 3.9 inches in depth. It features an external form factor design that makes it easily accessible and installable.
In RS-485 mode, the driver is automatically enabled during each space state by RS-232 signal presence. When RS-232 data is in mark or idle state, the RS-485 driver disables and data lines are held in mark state by a 4.7-ohm resistor. It supports both 2-wire half-duplex and 4-wire full-duplex operations, with specific switch settings for each mode.
The converter requires external power supplied through a terminal block connection. It specifically needs a 120-VAC/12-VDC Wallmount Power Supply (PS1003, sold separately) to function properly.
The converter is RoHS certified and TAA compliant. It's environmentally friendly and manufactured in the United States, meeting various regulatory standards for electronic equipment. The 2000-VAC isolation certification ensures robust protection between input and output circuits.
For RS-422 mode configuration, set Switch 1 to RS-422, Switch 2 to Echo On, and Switches 3 and 4 to 4 Wire. In this mode, the driver is always enabled for full-duplex communications, requiring a twisted pair for transmit, another for receive, and a ground reference wire.
The Black Box Universal RS-232 to RS-422/485 Converter comes with a 1 Year Limited Warranty, providing coverage against manufacturing defects and ensuring customer support during this period.
In 2-wire half-duplex RS-485 mode, the device allows connection to multiple RS-485 devices with minimal wiring. The configuration requires Switch 1 set to RS-485, Switch 2 to Echo Off, and Switches 3 and 4 to 2 Wire. In this mode, devices transmit data when requested and then return to receive status.
