Chapter 2: Getting Started 13 Chapter 2: Getting Started 2.1 Introduction This chapter provides basic instructions to get you started using the DSM300 Digital Sounder Module with a Raymarine hsb2 PLUS (Pathfinder) Series display. Instructions for operating the DSM300 with a C Series or E Series display are available in the handbooks for those products. This chapter also describes Simulator mode and helps you to become familiar with the basic functions of the display’s controls in Sonar operation mode.
DSM300 Operation with PLUS Series Displays 2.3 Selecting Sonar Mode If properly connected to an hsb2 PLUS Series Radar, Chartplotter or Fishfinder display unit, you can begin viewing echo sounder data by setting the display to Sonar mode. Note: Data, such as depth, speed, temperature, log, and trip are still available even if Sonar mode is not selected.
Chapter 2: Getting Started 15 2.4 Selecting Repeater Mode Depth data that is to be shared over the hsb2 network is sourced from the device that has been designated as the master sonar unit. Only a DSM300 or an hsb2 PLUS Series fishfinder display can be a master unit. For the DSM300 master to repeat its sonar image data to a display unit, the display must be designated as the REPEATER.
DSM300 Operation with PLUS Series Displays 2.5 Sonar Mode Display When you first switch the display unit into Sonar mode, the scrolling bottom graph is displayed. This is a graphical representation of the echoes seen by the DSM300. As time passes, this display scrolls from right to left and becomes a record of the echoes seen. A typical display is shown in Figure 2-2. The images at the right hand side of the display are the most recent echoes. Some echoes indicate fish, and others show the bottom.

Chapter 5: Sonar Mode Operation 63 Chapter 5: Sonar Mode Operation 5.1 Introduction Basic operation, including a description of the different display options, was given in Chapter 4. This chapter explains how to use the display unit to show sonar data. It describes how to fine-tune the image and use the controls to get additional information. Note: This chapter describes using the DSM300 Digital Sounder Module with a Raymarine hsb2 PLUS (Pathfinder) Series display.
DSM300 Operation with PLUS Series Displays 5.2 Interpreting and Adjusting the Sounder Image The DSM300 uses sound waves to find fish and show bottom structure. The transducer sends high-frequency sound waves into the water; these sound waves strike fish, the bottom, or other objects in the water and return as echoes. The DSM300 interprets these echoes to present an image of the fish and bottom. The strength of echoes is indicated by different colors (or shades of gray in monochrome displays).
Chapter 5: Sonar Mode Operation 65 The frequency of the transducer The same target will appear differently when the transducer frequency is changed. Generally, the lower the frequency the broader the image. Using White Line The White Line feature separates echoes from fish near the bottom and the bottom itself. When the White Line is switched on, the sounder displays the echoes differently. On color LCDs, the strongest echoes are displayed in the background color with a thin line on top.
DSM300 Operation with PLUS Series Displays GAIN ADJUST 200 50 You adjust gain for each transducer frequency independently. Press the GAIN ADJUST soft key to highlight the frequency for which you are making adjustments. You may change settings for one frequency while displaying the other. ➤ To adjust a parameter: MULTI GAIN GAIN ADJUST 200 50 1. Press the GAIN key or rotate the GAIN knob on radar CRT units. The gain sliders are displayed.
Chapter 5: Sonar Mode Operation 67 The DSM300 provides three pre-defined automatic gain settings: CRUISING is the lowest automatic gain setting. It is ideal for viewing sonar image with a minimum of background noise as you are travelling to your fishing spot. AUTO TROLLING is a slightly higher gain setting that displays more detailed echos as you search for targets. 45% CRUISING FISHING is the highest automatic gain setting.
DSM300 Operation with PLUS Series Displays STC GAIN MANUAL 15% STC STC (Sensitivity Time Control) reduces surface clutter by reducing the gain in the top 100 ft of the display. This function is useful for reducing noise (caused by air bubbles and floating debris) that often appears in shallow water. A low STC value has little effect on gain in shallow water; a high STC value decreases the gain in shallow water so that only the strongest echoes are displayed.
Chapter 5: Sonar Mode Operation 69 The top line status bar shows the condition of the alarms: • indicates an alarm is enabled. The speaker symbol is unfilled until an alarm is triggered and silenced, then the symbol is shown solid. • S indicates the shallow alarm is enabled; a pop-up window indicates when the alarm is triggered. • D indicates the deep alarm is enabled; a pop-up window indicates when the alarm is triggered. • indicates the fish alarm is enabled.
DSM300 Operation with PLUS Series Displays 5.3 Using VRM VRM/EBL The VRM (variable range marker) key is used in Sonar mode to determine the depth and distance-behind-boat of an object on the display. The VRM function is available on the scrolling sonar display, bottom lock, and zoom windows. A VRM is displayed as a cross hair with height and width of the display window. The center of the crosshair is the reference for which depth and distance-behindboat are displayed.
Chapter 5: Sonar Mode Operation 71 The cursor is positioned at the center of the crosshair and has control of the VRM, as indicated by four-way arrow, the solid crosshair and the text VRM. 2. Use the trackpad to position the center of the crosshair over the desired object. The depth and distance-from-boat are updated as you move the cursor. 3. Press ENTER to drop the VRM. The crosshair is displayed as a dashed line. ➤ To move a VRM: VRM 1.
DSM300 Operation with PLUS Series Displays Note: When in chart mode, if you place a waypoint at the cursor position, it is not shown on the display in Sonar mode. If you place a waypoint at the boat position in Sonar mode it is shown in the chart window.
Chapter 5: Sonar Mode Operation 73 ➤ To place a waypoint as latitude/longitude using the Waypoint List: MARKS WAYPOINT LIST 1. Press MARKS, followed by the WAYPOINT LIST soft key. The Waypoint List and associated soft keys are displayed. WAYPOINT LIST SYMBOL NAME WAYPOINT 001 WAYPOINT 002 WAYPOINT 003 WAYPOINT 004 WAYPOINT 005 POSITION BRG _186° 50°21^966N 001°20^368W RNG _21.
DSM300 Operation with PLUS Series Displays Note: To obtain MOB position, you need either of the following: • Position data from a GPS or equivalent device • Heading and speed data, so that the position can be calculated by dead reckoning MARKS ➤ To initiate the MOB procedure, press and hold the MARKS key for two seconds. The system then performs the following tasks automatically: • Marks the Sonar image with a vertical line and the letters MOB.
