    Functions and dialog boxes Sensor Setup dialog box - Fish Sensors page This page allows you to define which PI/PX catch monitoring sensors shall be used with the FM90 system. How to open Click the button. This button is located on the top bar.
  • Page 104 Simrad FM90 Reference Manual Description The FM90 supports up to six measures on six channels. This page allows you to configure the sensors so that the FM90 knows exactly what type of sensors are being used and where they are located. Update rate and communication channels are also defined. The channel number parameter is vital.
  • Page 105 This setting defines the channel number of the sensor. This is the communication channel used between the catch monitoring sensor and the FM90. If you use more than one sensor of the same type at the same time, the channel number on one of the sensors must be changed to make it unique for that particular sensor.

  • Page 106: Sensor Setup Dialog Box - Fish Receiver Configuration Page

    Simrad FM90 Reference Manual Sensor Setup dialog box - Fish Receiver Configuration page Use this page to improve the catch monitoring sensors receive signal. The default settings work in most environments. However, you can adjust these settings for specific environmental conditions.
  • Page 107 It will Sensor Filter average the data received from the sensors. The FM90 system is designed to quickly update data. After the sensors have been submerged, the receiver requires only three consecutive pings from individual sensors to calculate and display their respective information.
  • Page 108 Simrad FM90 Reference Manual • Weak The information from the last four sensor transmissions are averaged. • Medium The information from the last eight sensor transmissions are averaged. This has proven to be a useful setting for trawlers. • Strong The information from the last 16 sensor transmissions are averaged.
  • Page 109 FM90. Water Profile Use this setting to set up the FM90 for operation in fresh or salt water. Sound travels with different speeds in salt and fresh water. For this reason, it is important that the FM90 knows your water profile.
  • Page 110 These problems may occur if neighbouring channels are used, or if the FM90 is disturbed by other hydroacoustic systems in use on your own or other vessels. When you operate in areas with substantial reverberation due to the bottom conditions, or in shallow waters, you may experience “jumps”...

  • Page 115 Enter the port of the remote computer that receives the data. Note The FM90 software uses this network port to transmit information. The application on the remote computer will "listen" to this port number. You must then access the application on the remote computer to set up its local port to match.
