6 Using card edge controls
6.1 Introduction
Once the start-up initialisation procedure is complete, the TANDEM-300 card can be
controlled or configured from the card edge or the Statesman PC interface. This chapter
will concentrate on the card edge controls.
The front edge of the card provides power rail monitoring, menu selection, an analogue
audio monitoring output, rotary set-up controls and a ten-digit visual status display.

In general the Menu DIL switch is used to select one of four main menus, whilst the SEL
rotary hex switch selects sub-menus or internal variables. The ADJ shaft encoder is used
to assign values to variables (such as audio delay or routing assignments).
Changes made using the shaft encoder are generally not implemented immediately. The
display will normally flash alternately between bright and dim to indicate that the
displayed value may no longer be current when the ADJ shaft encoder is turned. To save
a new value simply toggle MENU switch 1 down and then up again.
