 +===== Description =====
 +LNet, a compatible sytem with LocoNetĀ® is popular because of its reliable and easy to use hardware.\\
 +So far GCA did not have a direct system for controlling servo'​s.\\
 +There was the very popular GCA136 unit, easy configurable within Rocrail.\\
 +To connect it to LNet, there always was needed a GCA50, which could handle two of these units, or one and combined with other units.\\
 +GCA183 is one step further.\\
 +It provides 4 outputs for servo'​s and additional equipped with 8 input ports, to be used directly with Hallsensors or IR sensors,\\
 +or to be connected to GCA93, GCA94, GCA133 or GCA173\\
 +Programming can be done exactly like the combination of GCA50 and GCA136,\\
 +GCA183 also provides connection for the relay-unit GCA137, to enable reversing power for frogs in switches.\\
 +Power supply can be done in two ways:\\
 +Jumpers on board will give you the choice of getting 12v supply from the LNET network itself, \\
 +or supply the board with external transformer.\\
 +The board itself is completely isolated from LNet when the external power supply is selected.\\ ​
 +For larger setups( i.e. more than 5 of these units in the network), the external supply is preferrable.\\  ​
 +This board also contains a standard RJ12 LNet connector, to easy adapt to LNet standard.\\

 +===== The prototype =====
 +To be able to finish the complicated development of the firmware, several prototypes have been made, \\
 +and are under various test situations now.\\
 +A professioinal produced pc-board and/or kit will only be available after these tests are finished completely and showed to be functional as desired.\\
