LP-8841
Embedded Linux Controller with Dual 10/100 Base-TX Ethernet Ports and 8 I/O slots, Linux Operating System. Supports operating temperatures between -25 ~ +75 °C (-13F ~ 167F). LP-8841 is phased out and replaced by LP-8841.
Features
The LP-8841 has officially been phased out and will no longer be available. It has now been replaced by LP-8821.
LinPAC-8000 allows enthusiastic Linux users to control their own embedded system easily within the Linux Environment. It equips a PXA270 CPU (520MHz) running a Linux 2.6.19 Operating System, variant connectivity (VGA, USB, Ethernet, RS-232/485) and 1/4/8 slots for high performance parallel I/O modules (high profile I-8K series) and serial-type I/O modules (high profile I-87K I/O modules).Users programs can be saved in external storage devices, such as microSD Cards, USB devices or RAM via Ethernet. A LinPAC SDK is provided for users to develop LinPAC I/O applications rapidly and easily when I-7000/8000/87k series I/O modules are used in the LinPAC. Users can develop LinPAC applications by using GNU C or Java Language. In the meanwhile, all kinds of servers and functions built-in make the LinPAC more powerful and users will be able to operate LinPAC to achieve their own project smoothly. With LP-8000 series, users can achieve the redundancy function and it will make the whole control system safer.
