With over 8 months of engineering and testing, Great Lakes Modular is proud to present the ultimate DCS trough receiver board! With highly sensitive IR

Some other shortcomings in the original design include high current consumption and heat generation, lack of indicators showing the status of the IR LEDs, and and just plain flimsy PCB construction.

The newly redesigned board has a number of significant advances that improve over the original:

• Highly sensitive IR sensors, yet filters almost all visible light!
• Tapered PCB conforms perfectly to the space provided and is significantly stiffer than the original, reducing board flex. Larger traces and pads for better reliability and longevity.
• Visual status LEDs allow for quick and easy troubleshooting of problems in the ball trough. Six green leds indicate the presense of a ball, while a seventh red LED at the far right indicates a ball in the jam location. As with the transmitter board, all LEDs are easily checked by opening the coin door!

In the above images, the receiver board can be seen under various operating conditions.
