IS15 Instruments as NMEA repeaters
Figure 6-20, Figure 6-21 and Figure 6-22 are examples of how
IS15 instruments can be used as NMEA repeaters. Depth, speed
and temperature can be displayed when connected to a Simrad
CEXX Chart plotter/Echo sounder or CAXX Multifunction
radar. Any preferred combination of instruments can be used, the
IS15 Combi for example is an excellent display also for wind
data presentation.
Installing the Roblink Power Cable
The configuration in Figure 6-20 is limited to a total of 3
instruments and a Roblink Power Cable (P/N 22093587) is
required to enhance the Roblink signals. Connect the cable to a
circuit breaker. Extend the cable if necessary using a wire gauge
of 0,75 mm
2
(AWG18).
Notes !
1.
If an IS15 Wind Transducer is connected to the IS15
instruments when using this configuration, it must be
plugged into connector no. 2 (Roblink) on instrument head
no. 3. Refer to note 2 for NMEA connection.
2.
If only a single instrument is installed (
) there is
no need for the Roblink Power Cable. Simply cut the 0,3 m
(1’) cable that comes with the instrument in two and extend
the halves to the 12V supply and the NMEA source
respectively using twisted pair cable. – Also refer to
instructions for Roblink turn-off (paragraphs 7.3 or 7.11.)
Installing the IS15 Power Supply
The IS15 Power Supply (P/N 22093595), like the IS15
Transceiver is capable of driving a total of 7 instrument heads. A
5m Roblink cable (P/N 22092548) is included as standard.
Figure 6-21 shows an example of this configuration.
The physical dimensions are equal to the Transceiver and the
connections are similar with the exception of the speed and depth
transducers. These connections are not applicable since the unit
does not contain depth sounder and speed/temp. electronics.
Please observe the total length of Roblink cables. See page 61.
Also observe the cabling instructions in sections 6.6 and 6.7.
