 +| {{:​mgv:​hardware:​gca141c_pict_01.jpg?​600}} |   IR led, not on this picture, ​  ​\\ ​  ​should be connected to J2   ​\\ ​ The 5 pin connector is conncted to GCA133 or GCA141 ​ | \\
 +To avoid any problems on longer connections between sensor and GCA133 or GCA141 board, the sensor is mounted on a little driver board.\\
 +In case of use for GCA141 wheelcounter,​ the outside of IRled , positioned between the rail, is liable to be short circuited to the rails by train wheels.\\
 +Precausions have been made to avoid that ths will cause damage to the IR-led, or any other parts in the system.\\
 +Extra power filter is on-board, to make sure the sensor is working according specifications.\\
 +The IR led can be connected to J2, or can be mounted straight on board, instead of J2
