EFIS Operation
This change is only used if the primary OAT (or entire DSAB network) fails and the EFIS switches to the
locally connected OAT.
ENGINE (Manifold Pressure and RPM)
The engine informational item allows you to display engine manifold pressure and RPM on the
EFIS page. This requires that the manifold pressure sensor and tachometer pickoff are properly
installed and configured on a DSAB-connected EMS-based product.
DIM – Changing screen brightness
In the EFIS > DIM menu, press BRITR or DRKR to change the brightness of the display. It is not possible to turn the
screen completely black. Note that if power to the EFIS-D10A is cycled, the screen is reset to full brightness.
The DIM function also exists in the EMS main page menu. You may dim the display via either menu.
All screens in a DSAB network share a common dim level. Pressing BRITR or DARKR on one unit changes
the brightness level on all screens if the change is possible. If you have any D100-series bright screen units in
the system, you must press BRITR on any bright screen unit to get the bright screen units to their final step of
brightness.
The HS34 and AP74 have built-in light sensors which can be used to automatically dim all of the screens
connected to a DSAB network (if both installed, their sensor values are averaged). To turn this function on,
press AUTODIM. When you enable auto-dim, the screen does not immediately change brightness. Instead, the
system records the unit’s current brightness level as the desired brightness. From that point on, all networked
units react to changes in light intensity and maintain perceived brightness at the desired level. If auto-dim is
enabled and the screen is too bright or dark, continue to use the BRITR or DARKR buttons as you would
