 +===== Need more Power? =====
 +It is possible that even his power supply does not match your needs.\\
 +So the idea comes near to use more than one GCA-06 units in the RocNet network.\\
 +Basically no problem but please use separate adapter/​transformer for supply of GCA_PI06.\\
 +Using the same adapter/​transformer for multi GCA_PI06 units can cause many unexpected problems.\\
 +It is strongly discouraged. \\
