4 Card edge operation
The control of the DEC104S will always follow the last control surface used. For
example, if a card edge lever is moved the unit will switch to and remain in the Local
Control Mode. If Statesman or any control panel menu is used, then the unit will switch to
and remain in the Remote Control Mode. The settings made will be remembered after a
power down and the last control mode used will be retained.
Piano switch and jumper settings are only read when they are changed. However, the
board will configure itself according to local configuration changes even if the changes
occurred while the board had been powered down.
The auto-configuration process performed when a DEC104S is first powered up, detects
the current configuration settings and restores the appropriate control. Once this
initialisation procedure is complete, the card can be controlled or configured from the
card edge, the frame’s local control panel, from a remote control panel or from Statesman.
Card edge controls
The front edge of the card provides LED status and power rail monitoring, menu
selection, rotary set-up controls and a ten-digit visual status display.
In general the six-lever switch changes mode or options whilst the SELECT switch is
used to select one of the main configuration menus and the ADJ shaft encoder is used to
assign values to configuration variables.
A change made using the shaft encoder is generally implemented immediately and there is
no need for a separate save or enter function.
