Echelon LonTal Stack - Manual (Page 19)

LonTalk Stack Developer’s Guide 7
develop your application using the Echelon LonTalk API to manage
communications between the LonTalk Host stack, Echelon Smart Transceiver or
Neuron Chip, and other L
ON W ORKS devices on the network.
The LonTalk Stack includes an example communications interface driver for the
serial link layer that manages communications between the LonTalk Host stack
within the host processor and the Echelon Smart Transceiver or Neuron Chip
with Layer 2 MIP. You need to include the physical implementation of the serial
link layer in your LonTalk Stack device design, and you need to create the
software implementation of the serial interface driver.
Comparing Neuron-Hosted, ShortStack, and LonTalk
Stack Devices
