Resumen
El SDM-SIO1A es un módulo de expansión puerto serie I/O para dataloggers Campbell Scientific. Se ha diseñado para añadir un puerto serie adicional RS-232, RS-422, o RS-485 (half- o full-duplex) a un datalogger compatible SDM, con el objetivo de interactuar con sensores inteligentes, actuadores o visualizadores. Se pueden conectar hasta 15 módulos SDM-SIO1A al puerto SDM del datalogger. El SDM-SIO1A se comporta de forma similar al puerto serie nativo del datalogger y utiliza los mismos típicos comandos de E/S serie. El SDM-SIO1A incluye protecciones contra transitorios y descargas en el interface puerto serie según norma IEC61000-4-5 level 4, lo cual evita tener que adquirir a parte un protector contra sobretenciones.

Descripción detallada
The SDM-SIO1A connects to a remote serial device using industry-standard hardware that can be set to true RS-232, RS-485, or RS-422 signal levels. When operating in RS-232 mode, the module also supports hardware handshaking. RS-422 mode is functionally the same as RS-485 mode, except the connection is limited to a point-to-point system. Connections and programming for RS-422 are otherwise identical to RS-485.
The SDM-SIO1A will accept serial data up to 6143 bytes and store it in its buffer. This allows remote equipment to transmit large amounts of data without needing to stop other processes in the datalogger.
Up to 15 SDM-SIO1A modules can be connected to a single datalogger using the SDM port, allowing a user to connect 15 different serial devices to a datalogger with ease. This is in addition to any connections made to the dataloggers via other serial ports.
The SDM Jumper Wire Kit (pn #32505) connects up to four SDMs to the datalogger. This kit is recommended when multiple SDMs are connected to one datalogger or for extremely short distances between the SDM and datalogger. The CABLE5CBL-L cable is recommended for connecting a single SDM to the datalogger, and for longer distances between the SDM and datalogger.
