IR301 Operation and Installation
1. Overview
The SKIPPER IR301 is a remote depth indicator for NMEA signals. It gives accurate digital depth indication
based on signals from the SKIPPER ED165, GDS101 or GDS102 echo sounder. SKIPPER IR301 can also
be used with echo sounders from other manufacturers, when these have an NMEA 0183 output. On the
SKIPPER IR301 the operator may indicate the position of the transducer, or select between transducers
(GDS102).
• SKIPPER IR301 is a digital depth repeater with independent alarm indication. The operator may select
to indicate depth alarm using the menus.
• SKIPPER IR301 will only indicate depth below transducer.
• Brightness is adjusted on the front panel, via NMEA or from the optional remote controller, IR30DIM.

3. Operation
1. To switch on the unit, press any key, to switch off, press both up and down keys at the same time.
2. To adjust brightness of LEDs, press up/down arrows to nd a suitable setting.
3. To select indication depth alarm, press the S key once and enter alarm setting mode, “SetA “. Set the
desired depth by using the up and down keys. When desired alarm depth is set, the unit will go back to
normal mode operation after 15 sec or press S key until the depth occur. When depth below transducer
becomes same or less than the set alarm depth, the display will indicate “AL “ alternating with actual
depth. To disable the alarm, repeat operation no 3, and set alarm depth to 0 m.
4. To select readings in feet (ft) meters (M) or fathoms (F), press the S key twice and enter units setting
mode “SetU“. Select wanted readings by using the up or down key. When readings is set, the unit will
go back to normal mode operation after 15 sec or press S key until the depth appears.
5. To select transducer position, press the S key three times and enter the position setting mode, “SetP”.
Press up or down keys to select between the four choices:
• Unknown,
• Forward,
• Backward
• Auto.
Mode Transducer position LEDs
Unknown Both LEDs off
Forward Forward LED on
Backward Backward LED on
Auto Active transducer position slowly ashing
• The “Unknown” selection decodes NMEA depth message and show the depth on the display. The
position LEDs will then be off. The other selections decode the NMEA message $PSKPDPT.
• If “Forward” is selected, only the readings from the forward transducer is shown. The same applies
for the “Backward” selection.
• The Auto selection switches between Forward, Backward and Unknown depending on the NMEA

4. NMEA Input
Accepted messages (received and transmitted) (NMEA 0183), talker identier is not processed:
Name Description Example Comments
DPT Depth $--DPT,xxxx.x,xxxx.x,xxxx.x <CR><LF>
DBT Depth below

$--DBT ,xxxx.x,f,xxxx.x,M,xxx.x,F)
DDC Display Dimming
Control
$--DDC,a,xx,*hh<CR><LF> Brightness percentage has priority over display
dimming preset.
Note: Baud rate xed to 4800 baud.
6. Service
• All service requests should be made to the local SKIPPER representative.
• Adjustments and repairs should only be performed by qualied service engineers, and unqualied repair
attempts will void the warranty.
5. Diagnostic information
• If the IR301 does not receive any signal from the external source for more than 3 seconds, “Error”
(“Err”) message is indicated on the LEDs. This may happen, for example if an external talker is not
connected or connection polarity is not correct.
• If input messages do not contain sentences required for indication of selected data, “_” (underline
symbol) is indicated on the corresponding LEDs. As an example: if there is no DBT message available
on the input, IR301 will indicate “_______” instead of depth.
• If elds in the received message is empty (not valid data), dots are indicated on the corresponding LEDs.
As an example: if the depth eld is empty in the $PSKPDPT sentence, “...” will be indicated instead of
the depth value.
NOTE: IR301 will always only indicate depth below transducer. I.e. draught is not processed.

messages available. The LEDs for the position will shift automatically and blink every third second
indicating that the Auto selection is active. If the transducer position is unknown, both LEDs will be
on and blinking.
Note: Repeaters can be remotely dimmed by:
• Using external buttons (IR30DIM) connected to the DIM UP, DIM DN and DIMKEY of each repeater.
• Pressing up down arrows on one repeater, when DIM lines are connected in parallel.
• Using the DDC (NMEA) command as described in section 4.
