The SDI 02 is a complete memory cards interface specifically designed for an industrial use and for a direct mounting on automatic machines. The accepted memory cards are the SD (Secure Digital) and the MMC (Multi Media Card), that are the ones actally provided of the best features concerning price, handling and reliability. The SDI 02 is a complete peripheral device, capable to write and read data on the listed memories supports, that must be linked to a master system through a serial communication in different types. A list of proper commands allow the master to exchange data with SDI 02 and let manage this data with typical resources of a disk as the Folders, the Files, the Attributes, the Protections, etc.

The memory card is organized with FAT16 standard and it can be used by any personal computer, as an external removable disk. This really simplify the data transfer and use in fact each PC, provided of memory cards interface, can read, write, copy, open the available files, without any limits.

Some additional features as the presence of a Power Supply Section that acceppts a wide range input, a Plastic Container that speed up the installation and an Optional Real Time Clock that adds a time reference to saved data, complete the product with an optimum price/performance ratio.

The SDI 02 is the suitable component in all the applications where big quantity of data must be managed, up to 2 GigaBytes maximum limit, by using a communication serial line that is normally provided by each automation and control systems, available on the market. The data can be managed only on site and in this condition the interface acts as a memory expansion of the master system or they can be transfer to another system. In the last case the memory card is removed from SDI 02 and then used by any other system capable to manage the FAT16 standard; thus it can be developed applications for data logger, data exchange, configuration, update, production data collection, etc.

The serial communication with the master system can be established through an Asynchronous Line buffered in RS 232 or TTL or alternatively through an I2C BUS Synchronous Line. The selection of the used serial line and of the relative parameters is comfortably executed with a specific Configuration Modality, directly accessible to the final user.

Hardware features of SDI 02, complete of possible options, are listed below:


In order to simplify the use of SDI 02 the grifo® has realized a management firmware that speed up the development of the user application program. Generally the firmware allows to use all the hardware resources of the interface through an high level File System; in other words the user doesn't have to interact directly with the described hardware sections, but simply manage the provided commands.
The general features of the firmwares, including possible options, are the following ones:

GMM xxx and SDI 02 create a Data Logger ables to acquires Digital Temperature from sensor TC77 and, through RS232 serial line, to stores data and time on a Secure Digital card.

GMM xxx and SDI 02 create a Data Logger ables to acquires Digital Temperature from sensor TC77 and, through I2C BUS serial line, to stores data and time on a Secure Digital card.


The SDI 02 firmware can be comfortably used through its rich list of commands that solve the typical data recording problems, as described in the following table:
