Interface
Modules
Up to three rectifier connector modules may be installed on the
backplane. These modules, shown in Figure 2-2, connect directly with
the rectifier interface boards (BJC1, BJC2, or BJC3). Each module
routes the signals between the external rectifier and the correct circuitry
on one of the rectifier interface boards. Various backplane modules are
also furnished with the optional circuit packs. These provide wiring
access to the circuit packs.
User Interface
and Display
The Galaxy SC’s primary user interface is a panel that includes a backlit
LCD front panel display, two rows of LEDs, two sets of test jacks, and
an array of simple pushbutton controls. See Figure 2-3.
The contrast for the front panel display is set by a thumb-wheel
potentiometer marked “Display Contrast Adjust” located on the inside
edge of the BJG Display Board. Open the front panel of Galaxy SC to
access it.
