TPT/XF Twisted Pair Transceivers
TPT/XF twisted pair transceivers provide a simple, cost-effective method of adding a LonWorks® transceiver to any Neuron® processor-based product. The addition of a +5Vdc power source, a Neuron 3120® or 3150® processor with associated memory, an oscillator, and application electronics are all that is needed to form a complete LonWorks control node.
- Available as either a 78kbps transceiver or 1.25Mbps transceiver
- Uses transformers to provide isolation from the twisted pair network bus
- Provides excellent common mode rejection
- Reduces susceptibility to ground loops
- Meets LonMark® interoperability guidelines
