Dynon Avionics EMS-D120 Installation Guide - Manual (Page 64)

DSAB Configuration
Initial Setup
Please refer to your EFIS-based product’s Installation Guide for detailed information on setting
up and configuring your DSAB network.
Brightness Configuration
In a DSAB network, changing the brightness level of one instrument affects all connected
instruments. Dynon Avionics sells D100-series instruments with both regular and bright screens.
Each instrument connected to your DSAB network must have its display type configured to
ensure that perceived brightness matches across all screens. To do this, enter the SETUP >
DSAB > BRIGHTNESS menu on each product in the system. If you purchased the bright screen
option for your EMS-D120, press TOGGLE to change the BRIGHT SCREEN status to YES.
Otherwise, ensure this is set to NO.
If the DIM setting of one of the screens in a DSAB network gets “out of sync” (some
dim, some bright), this can be corrected by adjusting the DSAB Bus Master screen to the
desired DIM and then performing a DSAB CONFIGURE.
Network Status
The STATUS submenu displays
information on all configured devices,
their serial numbers, their roles on the
network, and their status.
The first line indicates how many devices
are configured on the network. This
number is independent of the number of
devices actually currently turned on and
communicating. It simply reports how
many instruments were present during the
most recent execution of DSAB
configuration.
The next several lines indicate the available roles that the selected instrument can provide. A “*”
is placed next to the roles that the instrument is currently providing to the network. If any of
those roles cannot be detected (e.g., the EFIS’s compass has been disconnected), a “?” is
displayed next to that role. Any given instrument in the list can have one of the following
STATUS messages:
ACTIVE – The device is communicating normally on DSAB.
STANDALONE – During configuration as Bus Master, no other DSAB devices were found.
UPGRADE REQ – Device has a different firmware version than the Bus Master and thus
cannot communicate on DSAB.
OFFLINE – The specified device cannot communicate on DSAB or is powered off.
PEERS LOST – (Only appears on Bus Master) – The Bus Master was configured with other
DSAB devices present; however, all of them are currently offline.
