Power Supplies – Series 1000 Chassis
Front pair pr5 VDC
Rear pair provides –5 VDC
Every chassis has three switch cards. Each switch card handles one element of
video signals (red, green, or blue), and two of the switch cards also handle
keyboard and mouse signals (serial signals are switched internally by the serial
cards and are not routed through the switch cards). All switch cards have a
temperature sensor that may be read through the front panel display or through
the user interface.
There is one control card in every chassis. The control card coordinates actions
within the chassis and provides a serial port for user interface and control.
Several attributes of the Matrix-Hub are user-defined and may be set using the
control card (see Appendix A, Control Card Settings).
The user-specified input and output cards allow individual users to access
computer resources through the matrix switch. One video input may be routed to
one or more video outputs, but keyboard/mouse and serial inputs may only be
routed to one output at a time. Inputs may be switched to outputs in whatever
groups of video, keyboard/mouse, and serial are required by the user.
