Overview of frequency selection
If many acoustic systems are used simultaneously, due care must be taken to prevent acoustic
interference between the different instruments. Make sure you do not have any interfering
channel if you have a PI Receiver working simultaneously with an SR15 or SR70 Receiver.
Kongsberg Maritime Catch monitoring sensors communicate on a frequency range from
40 to 50 kHz.

SR15 and SR70 Receiver Units
• Frequency range: 39.4 to 50.5 kHz.
• An SR type receiver has 8 communication channels when interfacing the following
sensor/sensors:
– PX TrawlEye
• An SR type receiver has 16 communication channels (1 Low to 8 High) when interfacing
the following sensor/sensors:
– PX MultiSensor Mk2
– PX MultiCatch
– PX Universal
– PX Flow
PI50 and PI60 Receiver Units
• The PI50/PI60 Receiver Units frequency range is from 43.6 to 49.4 kHz. It works in the
same operational frequency band as PX TrawlEye sensor channels 4 to 8 and the rest of
PX sensors channels 4L to 8H.
• The PI50/PI60 Receiver Units channels are 1 to 30.
Make sure you do not have any interfering channel if you have a PI Receiver working
simultaneously with an SR15 or SR70 Receiver.
Lower frequencies are better for long range communications. If you need long-range
communication, you should use low channels.
