KVM Over IP

Implementing KVM over IP on a PC platform requires a hardware component to deliver the keyboard/ video/ mouse interfaces. To enable this, the okvm team is delivering “open source” PCI card designs (which anyone is free to build). These low cost PCI cards can be installed in any suitable PC system running the okvm Linux software, and they will implement the keyboard, video and mouse capture/emulation support required for a fully featured KVM over IP management server. The okvm KVM over IP...

LIN, A Low Cost Alternative of Micro Networking

LIN is a broadcast serial network comprising one master and many (up to 16) slaves. No collision detection exists, therefore all messages are initiated by the master with at most one slave replying for a given message identifier. The master is typically a moderately powerful microcontroller, whereas the slaves can be less powerful, cheaper microcontrollers or dedicated ASICs. Current uses of LIN combine several such networks — usually with 16 nodes — all linked to a CAN upper layer...

NetBurner’s Fully Customizable Ethernet to CAN Server

By Tim Shannon, NetBurner SAN DIEGO - NetBurner has introduced its first product specifically targeted at providing developers with a platform for interfacing Embedded Ethernet to Control Area Networks (CAN). This low-cost and high-performance device targets the most demanding and cost sensitive applications. Embedded Ethernet to CAN Bridge This fully customizable platform is based on the 32-bit Freescale Semiconductor MCF5234. Running at 147Mhz, the NetBurner CB34-EX provides a fully...

CAN “Brotherhood” : SDS, DeviceNet and CAN Kingdom

DeviceNet, SDS and CAN Kingdom are all based on the ISO 11898 CAN communication protocol and circuits meeting the CAN specification. This implies that modules following any of the protocols can be connected to a very same CAN-bus. However, when modules following different protocols are connected to the same CAN bus, most often problems will arise due to conflicting interpretation of messages at the application level. CAN Kingdom differs from SDS and DeviceNet in one major principle way: CAN...
