"""
Example of using two SNAP Pro wireless nodes to replace a RS-232 cable
Edit this script to specify the OTHER node's address, and load it into a node
Node addresses are the last three bytes of the MAC address
MAC Addresses can be read off of the RF Engine sticker
For example, a node with MAC Address 001C2C1E 86001B67 is address 001B67
In SNAPpy format this would be address "\x00\x1B\x67"
