INTRODUCTION
The RD301 remote display is made for use with the EA400/
EA600 and the EN 250 navigation echo sounder. It may also be
used with other echo sounders, if they have NMEA0183 output.
The RD301 is a depth repeater with alarm setting. The operator
may select alarm depth in the meny.
Maximum depth readings are 9999 m and a resolution of 0.1 m.
Brightness is adjusted on the front panel. Brightness can,
optionally, also be adjusted from a remote controller.
OPERATION
1. To switch the unit on: Press any key.
To switch the unit off: At the same time, press both the Up

3. To select depth alarm: Press the S key once and enter alarm setting
mode. The display shows “SetA“. Set the wanted depth by
using the Up and Down keys. When wanted alarm depth is
set, the unit will go back to normal mode operation after 15
seconds, or press S to the depth occur. When depth below
transducer become the same, or less, than the alarm depth,
the display will indicate “AL“ alternating with actual depth.
To set alarm off: Repeat operation number 3. and set alarm
depth to 0 m.
4. To select readings in feet, meters or fathoms: Press the S key
twice and enter alarm setting mode. The display shows “SetU “.
Select requested reading by pressing the Up or Down key. When

key three times and enter the transducer selection mode. The display shows “SetP”. Press the Up/Down keys to select between
the four choices: Unknown, Forward, Backward or Auto.
- The Unknown selection decode any NMEA depth message and

off.
- The other selections decode the NMEA message $PSKPDPT.
If Forward is selected, only the readings from the forward
transducer is shown, and if Backward is selected, only the
readings from the backward transducer is shown.
- The Auto selection switches between Forward, Backward
and Unknown depending on the NMEA messages available.
The led for positions 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.
