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.
