- Company overview
The main business of Nissin systems is sales, maintenance and professional service of embedded software, which include the real-time Operating System and based on the network technology.
As the engineering company, Nissin Systems developed own real-time operating system, called N-Kernel, based on μITRON 4.0 technology.
And we also developed TCP/IP protocol stack software called USNet/Plus.
Furthermore, we provide the SDK for LANTRONIX's serial to Ethernet conversion module. This SDK include N-Kernel, USNetPlus, and some network protocols.

- Exhibit introduction
・μITRON development kit
It is a development kit that transplants μITRON4.0 conforming OS(N-KERNEL) developed by Nissin systems for each platform of the device made by LANTRONIX company server, XPortAR, XPort, WiPortNR, UDS1100, and UDS2100, and mounts standard network protocols such as the TCP/IP protocol stack, SMTP/POP3, HTTP, FTPs, and TELNET as a library to develop the application software on that.
The outline of this product is as follows.
- Real-time Operating System for μITRON 4.0
- Correspondence middleware
Client libraries
TCP/IP,SNMP, HTTP, FTP, Telnet, SMTP, POP3, and NTP
- Borland C++ 5.02J、Turbo Assembler 5.0J
- Correspondence hardware (XPort and either XPortAR, UDS1100 or UDS2100)
There is no mass production royalty for the software such as OS, TCP/IP stacks, and SNMP stacks included in this kit needing when the commodity of the customer is developed by using the firmware developed with this kit.
