//
// Simple sketch to interface to the 'Relais Interface Grundgerät'
// (http://www.ak-modul-bus.de/stat/relais_interface_grundgeraet,pd10!0,,RIST.html)
// The atmega328 is wired directly to the 20 pin DIP socket of the
// original microcontroller (AT90S1200).
// 
// This sketch uses an Ciseco XRF to transmit/receive data wirelessly, it relies
// on the Ciseco LLAPSerial library - https://github.com/CisecoPlc/LLAPSerial
//
// Functions supported:
//
// * aR8RELAY#ON- (turn relay # on)
// * aR8RELAY#OFF (turn relay # off)
// * aR8RELAY#TOG (toggle state of relay #)
// * aR8RELAYAON- (turn on all relays)
// * aR8RELAYAOFF (turn off all relays)
//
// Pinout of AT90S1200 socket
