New Power over Ethernet (PoE) white paper

We’ve just put out our newest white paper, on the subject of Power over Ethernet (PoE), also known as IEEE 802.3at. This technology makes it possible to deliver power to networked devices simply and easily, using existing network cabling. Power can be added to a network using either PoE endpoint devices (these are, for example, […]

OBDII Automotive Diagnostics and serial port connections

Vehicles manufactured after 1996 have a capability that few drivers realize exists: your vehicle has an interface to its computer that can provide a panoply of information about your vehicle’s operation and status, second by second. This interface, the On-Board Diagnostics (OBD) port, gives information on speed, acceleration, fuel use, temperatures (of oil, coolant, air […]
