INTRODUCTION. The Multi Repeater
_____________________________________________________________________
The SKIPPER Multi Repeater allow important values from a variety of systems to be
displayed anywhere on the vessel. The CD401 Compact display is unique in its simple
and exible way to display vital data in almost all conditions, from no light to bright
sunlight. In addition, it is classed to IP 56 allowing it to be mounted outside and used
in any conditions. The unit is a standard 144 mm format allowing it to be mounted in
tight spaces or overhead.

Pulses of at least 60 ms on the dimming up and dimming down cables will cause the
dimming to change by one level. The inputs are optocoupled and therefore require an
external voltage to operate, (5 Volt -24 Volt (Typically 5/12/24 Volt)).

_____________________________________________________________________

The Compact Multi Repeater Display is a exible dot matrix LED display designed
to display navigation data. The Multi Repeater can be user programmed to show most
kinds of numerical data from NMEA messages. The Compact has three user denable
alphanumeric displays, each allowing up to 4 lines to be displayed.

The Compact Display starts up in runtime mode. By pressing the MENU button, the
preset runtime screens can be selected. The unit can be dimmed in any of the runtime
screens using the UP (↑) and DOWN (↓) buttons.

To change the setup of the Multi Repeater, the user must simultaneously press MENU
and SET buttons. This will give access to a menu system allowing the user to scroll
up and down the sub menus and functions using UP and DOWN, and SET button to
select. To move back and up a menu, the MENU button must be pressed. The middle
underlined line is the selected line. The other lines are dimmed.
The menu structure is shown in the MENU DIAGRAM.
Press both MENU and SET buttons to activate the menus. Press and hold MENU to
return to runtime screen.

The system can be made to shift, with a ve second period, between the activated

The system has three user preset runtime screens (SCR1, SCR2, SCR3). The Screen
Menu allows the user to congure and choose which runtime screens to be included in
normal operation. UP and DOWN buttons will scroll to the available screens. By using
the SET button, the user can control each individual screen to ON, OFF or SHIFTING.
Screens set to ON are available to be displayed by pressing the MENU button. Screens
set to OFF will not be displayed. Screens set to SHIFTING will be shown on the
display periodically. Each shifting runtime screen will
be displayed for 5 seconds.

The programming of parameters to show on the screen is very exible. It is advise to
add leading text before the parameters and not mixing too many dierent messages. A
typical conguration is to show two related parameters on the screen simultaneously
with leading text. Arrows are added to some parameters for better readability. Press
MENU and SET button simultaneously to enter the screen menus, select CONFG and
then select wanted screen menu (CFG1, CFG2 or CFG3) to start to congure wanted
screen menu. See chapter 2 ”Setting up and using the Compact Display” on how to
program the display to show wanted information on the screen.

The 3 user programmable screen menus can be set up using
the Cong (CONFG) menu. This submenu allows the user
to select one of the three screen menus, and on entering
the Cong screen menu, the user can change the data type
to be displayed in each of the 4 screen menu’s positions.
UP (↑) and DOWN (↓) will change the data type, SET will
move to the next screen menu position.
Placing text (TXT) in the bottom 4th line or 3rd and 4th line will cause the data to spread
out showing fewer data points. The system will not allow you to mix speed data from
dierent sources on the same screen. Having two text (TXT) lines after each other will
also rearrange the positioning. (See examples on next page).
The non-active parameters will continue showing the dimmed present data, when not
selected. Some combinations of data are not allowed, as they may cause confusion.
These will be automatically corrected. Note that the leading text is identical for some
data, and information about talkers are ignored. Regulations require the user to be able
to identify which data they are looking at. This can be achieved by using the TXT
function or a sticker on the unit.

Depth
The NMEA sentences DPT, DBS, DBT, DBK and PSKPDPT are all supported for
receiving information about the depth. The use of the DPT sentence is recommended
when available. Depth values in feet and fathoms (from DBK, DBT and DBS) are
converted to meters. The screen will display either DEPTH-S (depth below surface),
DEPTH-T (depth below Transducer) or DEPTH-K (depth below keel) depending of
the received sentences (DBS, DBT or DBK) or the oset value in DPT. The proprietary
sentence PSKPDPT is able to distinguish between both transducer location and channel
number. The transducer location is indicated by an arrow in the text line. The channel
number is selected by parameter PDPT1, PDPT2 or PDPT3 and is written in the text
line as DPT1, DPT2 or DPT3 respectively for each channel. The parameter name PDPT
will ignore channel number and is written in the text line as DEPTH.
The depth is always displayed in meters. Depth values below 10 meters are displayed
with 2 decimals, depth values between 10 and 100 meters are displayed with 1 decimal
and depth above 100 meters are displayed without decimals.
Maximum depth value to be displayed is 9999 meters.

Speed
The NMEA sentence VBW is supported for receiving information about the speed
through water and speed over ground (bottom) for longitudinal, transverse and transverse
aft. The NMEA sentences VHW and VTG are supported for receiving information about
relative speed.
• An arrow, indicating the direction, is added in front of the value for speed values
from the NMEA sentences VBW.In the case of 2 VBW messages from separate
SOG and STW sensors, both can be used as long as the unused elds are left blank.

• The relative  is fetched from the NMEA sentence VHW.
• The relative speed over ground is fetched from the NMEA sentence VTG.
• Speed value in km/h is converted to knots if speed value in knots is not available.
• Relative speed is displayed without arrows.
• All speed values are displayed in knots with either one or two decimals depending
of the congured parameter to display. STW2L, STW2T, SOG2L and SOG2T will
always display speed below 10 knots with two decimals and speed from 10 knots
and above with one decimal. All other speed parameters are displayed with one
decimal (see the detailed description of the parameters in Appendix 2). Maximum
speed value to be displayed is +/- 99.9 knots.

Heading
The NMEA sentences VHW, VTG, THS, HDT, HDM and HDG are all supported for
receiving information about the heading. It is recommended to use THS instead of HDT,
and HDG instead of HDM when available. The deviation and variation parameters in
HDT are ignored.
If the same heading parameter is received from dierent talkers, the heading parameter
will be prioritized as shown below:
1. Gyro, north seeking (HE).
2. GPS (GP).
3. Compass, magnetic (HC).
4. Others.
An arrow is added on the text line to indicate which direction the bow turns. If no
