Card edge monitoring
The front edge of the card provides useful power rail monitoring, input status, vertical
filter and analogue output format.
Board edge control was removed from Q-Down-AG 3G and Q-Down-ATG 3G in
2018. Therefore the card edge control information is only relevant for older versions
of the product.
