Built-in type product is needed of connecting with TCP/IP protocol. Though materializing this, a real time O/S(RTOS) is needed but it is still very expensive because of building a development environment and license fee etc. and what is more, available RTOS is unfamiliar to general developers at present therefore it is necessary to acquire expert level of technology to develop products that utilize RTOS, and quite a long time will be spent to acquire a stable O/S and application software.

Products, which are implementing Embedded Linux on the basis of PC 104, are large in size and very expensive. Additionally, it requires another expense to implement a total system, because users must purchase it separately and install boards complying with PC 104 to add necessary circuitry.

Therefore LINUDIX provides an Embedded Linux platform, chip type CPU module mounted with Linux for Internet connectivity with you. LOC is ten times as small (1/4 business card size) as PC 104 based PC, so it is possible to install it on the smallest area of the board you want to develop and to implement Embedded Linux-based Internet connected products at a reasonable price.

It is a board for evaluation able to be used as a simple development tool for testing LOC functions. If you connect the RS-232C port of PC in which a terminal emulsator program such as Linux minicom or Windows HyperTerminal is stored to the RS-232C port of the evaluation board and supply electric power, the booting process is displayed on the terminal screen and finally a prompt is displayed.

LOC operates as a Linux machine providing the same interface as desktop Linux. The user, after he/she sets up the IP address suitable to his/her own LAN (The setting example is showed in the operating manual) can visit the basic home page stored in LOC by using the provided GCC compiler, or immediately perform a simple function test after he/she prepares/complies the same program as "Hello Linux " on the host PC and stores it in the LOC using NFS and implementing it.

The user familiar with TCP/IP or other technology can implement a gateway that is able to connect the equipment with built-in RS-232C to Ethernet using only the evaluation board.
