How to Solder an 8-Pin Transducer Connector on a Sitex CV106

The Sitex CV106 is a portable fishfinder mounted inside boats to help locate fish underwater. The device uses echolocation -- a type of sonar technology that sends an electronic pulse from the transducer into the water. If it locates fish, or other objects like sunken logs, its signal bounces back and is displayed on a monitor. The transducer on the Citex is connected via an eight-pin connection cable. These connectors are durable and are able to withstand dampness and humidity. However, soldering the eight-pin connector can help to reinforce the transducer's ability to transmit information with less interference.

Instructions

    • 1

      Disconnect the power cable by unplugging it.

    • 2

      Loosen the back panel on the fish finder, using the screwdriver, so both the outer and inner sections of the eight-pin connection port are visible.

    • 3

      Plug the eight-pin connector plug into the port. The terminal pins from the plug will be visible and accessible on the inside of the port.

    • 4

      Heat up the soldering iron, and then hold the solder above each connector pin. Melt a small dab of solder onto the each of the eight pins to solidify the transducer connection.

      Replace the back panel and screws, and reconnect the power cables.
