| + | ===== Description ===== | ||
| + | LNet, a compatible sytem with LocoNet® 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.\\ | ||
