4-14 DSM250 Digital Sounder Module
Target Depth ID
You can select whether the depth is shown for sonar echoes dis-
played on the screen. When Target Depth ID is set to
ON
, the
depth is displayed just above each fish echo. When set to
OFF
, the
depth of each echo is not displayed.
Color Bar
The color bar indicates the range of echoes displayed in each
color (shade of gray for monochrome displays). When set to
ON
the color bar is displayed on the right hand side of the display.
Depth Digit Size
The depth under the boat is displayed in the bottom left hand cor-
ner of the display. You can select small or large digits for the
depth display.
Sonar HSB Mode
Note: This parameter only pertains when the display to which you
are outputting DSM250 image data is a PLUS fishfinder. If your dis-
play is a PLUS radar or chartplotter display, the REPEATER setting
is automatically selected and cannot be changed.
The Sonar HSB Mode setting designates whether the display
showing sounder data is the
MASTER
unit from which depth data is
to be sourced or a
REPEATER
of sonar data received from a master
unit. Only one unit should be designated the master at a time.
Note: Ensure that there is only one sonar master unit on the hsb 2 net-
work. Having more than one master unit will cause unpredictable re-
sults.
A sonar
MASTER
unit is connected directly to the transducer. Only
a DSM250 or a PLUS fishfinder display can be designated as the
master. A
REPEATER
display is connected via
hsb 2
to the master
unit so it can display sonar data the master has collected. A
REPEATER
can be a radar, chartplotter or fishfinder display.
Because the DSM250 does not have a display of its own, the
DSM250 is
always designated as the
MASTER
. Therefore, all dis-
play units showing sonar data from the DSM250 must be desig-
nated as a
REPEATER
.
