Chapter 5 Installation CVS-126 Chapter 5 Installation 5.1 Item of Caution on Installation To exercise fully the performance of echo sounder, the installation of CVS-126 must be performed by an engineer who is officially authorized by our company. The installation work includes the following content.
CVS-126 Chapter 5 Installation The equipment is not waterproofed. Avoid excessively damp place. Do not install the equipment in place suffering from excessive water-drops. Otherwise, the inside of display window mists over or corrosion may occur inside. Laying and Connection of Cable (1) Keep the transducer and power cable as far away from the cables of other electronic equipment as possible.
Chapter 5 Installation CVS-126 Desk-top Installation (1) Loosen the knob bolt fixing CVS-126 Display unit to the mounting bracket, push the unit to the left side and pull the unit upward. CVS-126 Display unit Knob bolt Turn two turns the knob bolt to loosen it and pull the unit upward. Fixing screw 4 (2) Place the removed unit to a safe and flat place.

Chapter 5 Installation CVS-126 5.3 Installation of Transducer The standard installation of this echo sounder is shown in figure 5.5. Figure 5.5 Installation of Transducer In case of Inner-Hull Using the optional inner-hull kit (MFB-04), install the transducer to the inner side of ship’s bottom. Caution on installation Figure 5.6 Inner-Hull Installation (1) Select the location where no bubble is generated during navigation. (2) Select the relatively thin location of ship’s bottom.
CVS-126 Chapter 5 Installation In case of through hull Install the transducer directly to the ship’s bottom Installation Procedure (1) Select the installing location. (2) Remove the fixing nut and one piece of rubber packing. (3) If the slope of ship’s bottom is greater than 5°, make a wooden base to fit to the slope of ship’s bottom. To reduce the water resistance, cut the bow direction tip of wooden base at the outer side of ship’s bottom in the triangle shape.
Chapter 5 Installation CVS-126 5.4 Wiring Connection of Cable to CVS-126 Display unit Connect the power cable and transducer to the connectors of CVS-126 Display unit. POWER Power input 10.8~31.
CVS-126 Chapter 5 Installation Connection of Power Cable and Transducer Connect the power cable to the [POWER] connector and the transducer to the [TD] at the rear of CVS-126 Display unit connector. Connection of DC power cable (CW-264-2M) 3.5 stereo jack To [POWER] connector DC+ (Red) DC- (Black) Caution: Wind the insulation tape around the un-used lead wire for core-wires not to contact each other. Connection of transducer To [TD] connector Grounding • Use heavy gauge cable for grounding wire.
Chapter 5 Installation CVS-126 Connection with Speed Sensor or Water Temperature Sensor (Option) When installing the optional speed sensor or water temperature sensor, connect to the [TD] connector together with the transducer via the transducer cable (Type: CW-840-0.3M). For wiring, see the figure below. After soldering, implement the waterproof and insulation treatment on the connected part with the self-melting tape.
CVS-126 Chapter 5 Installation Connection of External Speaker (Prepared by a customer) The ø3.5 stereo jack is provided to the power cable. If you connect the speaker with the amplifier to the external, you can clearly hear the sonar sound. Adjust the volume of speaker with the amplifier equipped to the speaker 3.5 stereo jack 5.5 Serial Data Input Data The sentences of GGA, GLL,HDT, MTV, MWV, RMC, VHW, VTG and ZDA can be received. The type of NMEA0183 Ver.1.5, Ver.2.0 and Ver.3.0 can be inputted.
