sr-201-relay.py
===============

  sr-201-relay.py primary job in life is to document how to
  configure and control the SR-201 Ethernet relay, including
  a working example.  The documentation is in the source code.
  
  Because it is a working example it can also be used to
  configure and control a relay.


Dependencies
------------

  - Either Python 2 or Python 3.
  - Tested on Linux only.


Building, Installing and Running
--------------------------------

  There is no building required, and the only installation
  consists of download a copy of sr-201-replay.py to the current
  directory and making it executable.

  The factory default IP Address of a SR-201 is 192.168.1.100.
  To get started power it up via USB, connect a Ethernet cable,
  ensure you can ping that address, then run these commands:

      ./sr-201-relay.py			# Displays help
      ./sr-201-relay.py 192.168.1.100	# Displays the configuration
