CARD EDGE CONTROLS
The 7711HDC series modules are equipped with an 8 position DIP switch to allow the user to select
various functions. All positions are assigned sequentially such that the DIP switch 1 is located at the top
of the DIP switch (farthest from the card ejector). Table 5-1 gives an overview of the DIP switch functions.
Sections 5.1 to 5.2 describe the assigned DIP switch functions. The On position is down, or closest to the
printed circuit board. There is also a toggle switch and pushbutton which are used to navigate the on
screen menu. (See section 6)
