 +^^^^By Fred Jansen and Peter Giling ^^^^
 +===== Description =====
 +This a very nice and cheap way to switch leds on and off, with a timing included in Rocrail.\\
 +Also a dedicated program is available to control the boards directly.\\
 +The board is connected to the serial (COM) port of the computer and controls 8 leds individual.\\
 +A protocol called SPL is used to control the leds, and also a special command is included to change address of this board.\\
 +The board can be connected into a chain of more than 50 boards, all with individul pre programmed address.\\
 +Supply of 5 V is needed, which should be adapted to total demand of power in the chain.\\
 +A nice supply unit for this could be [[http://​wiki.rocrail.net/​doku.php?​id=gca08-en|GCA08-1]] or [[http://​wiki.rocrail.net/​doku.php?​id=gca08-en|GCA08-3]].\\
 +
 +===== Firmware =====
 +The firmware is simple and could be dveloped in basic , using PicSimulator IDE form www.oshonsoft.com.\\

 +^ N.B. Only complete ordered kits will be supported! ^
 +
 +===== Connections =====
 +To give the user multiple choices of how to connect the board, there are several options.\\
 +Explanation and drawing are pending.......
 +
 +
 +=====The final result =====
 + 
 +A nice pc-board is available, in the same quality you are used to from GCA.\\ ​

 +===== Stand alone controller =====
 +
 +A standalone control program is available from www.modeldigitaal.nl\\
 +
 +===== Connection LM 2 to PC. =====
 +One of the LM2 boards should be connected to PC as follows:
 +^  Connector J1 or J2  \\  GCA_LM2 ​ ^  Sub-D9 ​ \\  ComPort PC  ^  Function ​ ^
 +|  - (min)  |  5  |  Ground ​ |
 +|  S  |  3  |  Send, Tx  |
 +
 +===== Connection between ​ GCA-LM2 boards =====
 +Boards could be connected from one to another by using either J1/J2 or with the use of flatcable and J5.\\
 +In case J1/J2 just use 3 wires: \\
 ++  to +\\
 +s to s\\  ​
 +- to -\\
