-GCA101v1 was ready for an update.\\
 Since DC power supplies are getting cheaper, this unit does not need a special on-board power supply.\\
 So the new design is smaller and fitted with a very compact and good quality switching regulator for the 3.3V.\\

 The GCA101 is equipped with a special Ethernet connector.\\
 It provides an electric isolation , which means that computer and your trains are not electrically connected together.\\
-The standard Ethernet cable can be one of the two types. Either normal or 'crossed'  cables are useable. \\

 If you do not like this situation, use a dedicated cheap router for it.\\
 Direct connection GCA101 to PC is possible but requires some experience with networking.\\
+===UDP notes ===
 One important mark to old left-over routers:\\
-Routers previously used at home with your previous Internet/ Tv provider, will experience problems with connection via UDP.\\
+Routers previously used at home with your previous Internet/ TV provider, will experience problems with connection via UDP.\\
 This is probably caused by the UDP channel inside the router, which should be opened by passwords/codes/pin numbers.\\
-In this case, that router is unuseable.\\
+In this case, that router is unusable for UDP communication.\\
 One other problem might cause no connection in Windows.\\

+The Ethernet module in you pc might be not the only one.\\
 In that case Windows sometimes has a problem to decide where LocoNet communication should be sent to.\\
 Best way to solve this, is tot find out which inside ethernet adapters are not used, and shut them off in Windows.\\
