+==== Connection variant 1 ====
+Advantage: Power is fed via Ethernet cable. Disadvantage: Occupies Ethernet cable.
+<code>
+[HR20] <--- Ethernet cable ---> [Converter module]
+Converter module supplies both power and serial. If two HR20s should be controlled, then the same Ethernet cable can be used. Four wires per module suffice (Gnd, +3.3v, Tx (TTL), Rx (TTL) ).
+HR20a:
+Power(Gnd) - Rx: T568A/B White/Blue (4) -  Blue (5) cable pair
+Power(+3.3) - TX: T568B White/Orange (1) - Orange (2) cable pair
+HR20b:
+Power(Gnd) - Rx: T568A/B White/Brown (7) -  Brown (8) cable pair
+Power(+3.3) - TX: T568B White/Green (3) - Green (6) cable pair
+</code>
+==== Connection variant 2 ====
+Advantage: Power is fed via PoE Module. Can be routed further if a PoE Router is being used.
+HR20 with PoE PD module integrated
+==== Connection variant 3 ====
+HR20 without PoE PD module. Power for the HR20 and Ethernet/wifi to RS232 converter is fed via a separate power supply.
+===== Master/Slave connectivity =====
+Each HR20 is per default connected to the master connecter. An additional slave output can be used to connect another slave.\\ \\
+Adapter cables convert RJ45 to DIP10. This requires a small module with multiple RJ45 connectors.
+==== Unsorted ====

+=====
+I've build a HM-11 Module into a "prototype" HR20-BTLE Version.
+====
+FYI,
+I just got around to programming the rest of my thermostats, and had to
+do the following:
+sudo avrdude -p m169 -c dragon_jtag -e -B 12 -U flash:w:hr20.hex
+sudo avrdude -p m169 -c dragon_jtag -U hfuse:w:0x99:m
+sudo avrdude -p m169 -c dragon_jtag -e -B 12 -U flash:w:hr20.hex -U
+eeprom:w:hr20.eep -U hfuse:w:0x91:m
+If I didn't flash the hex first, I was not able to set the fuse.

+Security of HR20:
+The best description I know of is in repository,
+rfmsrc\doc\hr20-security.pdf

+HR25:

+(Compile with make hr25. The resulting hex file will be hr25.hex)
