User manual SIMRAD PI REMOTE QUICK REFERENCE GUIDE REV A

[. . . ] Daily operation The PI Remote/Depth dual sensor will automatically be switched on once the waterswitch is activated. After startup, the sensor will communicate with the PI Spread sensor to measure the distance between the two trawl doors. [. . . ] (E) Using the transverse communication link, the two C sensors measure the distance between the trawl doors. Main items (A) Negative charging & fastening lug (B) Positive charging & fastening lug (C) Communication link to the vessel (D) Transverse communication link (E) Spread and Remote set identification (F) Water switch with sacrificial bolt (G) Sensor identification label for the sensors, but they must also allow for free water circulation to allow the sensor's water switch to engage. Also, the design of the inserts allows sand and mud to flow out when the trawl doors are pulled up from the water. Sensor configuration On delivery, all Spread sensors are configured as follows: Remote: Remote 1 Depth: Channel 11, 15 or 13 / Fast Note: The sensor and the PI system setup must correspond, otherwise the communication will not work. To change the setup, use the PI D B E A G F (CD012201A) Configurator utility. The sensor update rate controls how often the sensor reads and reports the depth. Three settings are available; Fast, Normal and Slow. Note that a faster update rate will decrease the battery life. Numerical presentation The numerical presentation of the PI Remote/Depth data is automatically shown in the relevant display modes. It is identical to the presentation provided by the PI Depth sensor. When the readings are stable, the digits are shown in black colour. [. . . ] (B) The PI Remote/Depth sensor is mounted on the starboard door. (C) Communication link between the PI Spread (or Spread/Depth) sensor and the PI hydrophone, provides distance information. (D) Communication link between the PI Remote/Depth sensor and the PI hydrophone, provides depth information. [. . . ]
