 +===== Features =====
 +- up to 4 WA2 drives can be connected.\\
 +- green/led signal for each drive indicates position.\\
 +- separate feed-back for each drive.\\
 +- polarity relay for turnout frog\\
 +- Automatic fuse protection for turnout frog\\
 +- supply 8 - 12 V ac/dc
 +
 +===== Description =====
 +This interface is specially ment to be used with the nice Bohler WA2 turnout drive.\\
 +It provides an extra relay for high current switching of the polarity of the turnout frog..\\
 +Also a feed-back is generated, back to either GCA50 or CAN-GC2.\\
 +In case of wrong polarity of the frog, depending on how the drive is mounted, a fuse is on board to take care that everything will survive even with high current DCC power boosters.\\
 +Polarity is to be corrected by swapping the two booster lines on appropriate connectors HS1..4.\\
 +The fuse is self resetting and an indication led will show that the fuse is activated.\\
 +Also extra connection of a light in the turnout lantern is available.\\
 +The internal switch of WA2 is used to activate Frog relay.
