MYW868B/CP WIRELESS YACHT CONTROL SYSTEM Operating Instructions

PREFACE PRECAUTIONS The MYW868B/CP is a RF microprocessor based yacht remote control system specially designed for yacht engines, bow thrusters and anchor windlass controlling. The high quality foil keyboard and relays together with a special software protocol enable high reliability yacht controlling. The transmitter is built in an ergonomic and waterproof casing which enables simple management and bearing. This remote control system comes in three versions. Version MYW868B/CP-3 controls the vessel’s engines and anchor windlass; version MYW868B/CP-4 controls the vessel's engines, anchor...

DESCRIPTION The Wireless Yacht Control System MYW868B/CP is composed of transmitter and receiver units. The transmitter - 'Remote Controller' – is fitted in ergonomic plastic casing and is managed by operator. The receiver is installed in a suitable place and it has all necessary electronics for connection to the motor boat control systems. MYW868B/CP has many systems to achieve safe and high reliability: • Frequency and output power: MYW868B/CP is designed for ISM/SRD frequency band 1f – 868.000 to 868.600 MHz, and works at frequency 868.2772 Mhz. The fact that output power is limited and...

The receiver can receive data with errors or the receiver can miss the complete data packet. The decision depends on current status - moving boat (when at least one key is pressed or switch moved) or stopped boat (when no key is pressed or no switch is moved) Moving boat decision: The receiver is able to correct or cancel all wrong data packets. After the fifth consecutive error in data packet the boat is stopped (this means that all the controls of any motor from the side of MYW868B/CP are stopped) and the sound signal and LED signal announce that there is problem with the communication....

CONTROLS AND CONNECTORS MYW868B Basic Unit (Receiver) (8) Relay LEDs LEDs to show which relays are activated. For every pressed keys or switch one double relay is activated and LED lights. (1) DC Terminal block to connect DC power supply 12V to 24V. (2) BZ Terminal block to connect optional external buzzer. Standard buzzer is mounted on the casing and already connected. (9) Receive LED LED to show the signal interruption. If the received signal is not correct the LED starts to light and buzzer is activated. (3) PORT ENGINE Terminal block to connect control wires of port engine command. (10)...

MYW868CP Remote Controller (Transmitter) (1) Anchor windlass control – up/down By pressing the control keys the anchor windlass is activated to move anchor up and down. (5) Transmitt LED The green LED indicate the transmission mode. When one or more keys or switches are pressed the LED starts to blink quickly. (2) Port engine control – forward/reverse By pressing the port control switch the system will command Ahead or Astern with Idle RPM. (6) Low Bat LED The red LED indicate that the battery voltage is too low for operation. The battery have to be replaced as soon as possible. (3) Power...

INSTALLATION The system consists of the following components: • • • • • • • MYW868B basic unit MYW868CP remote controller Resistor adapters pack Antenna 2 x CR2 battery Strap Wall-mount bracket with screws All the diagrams in this manual show the installation of the remote control system to the motor boat of a complete twin engine propulsion system with built-in anchor windlass, bow and stern thrusters. MYW868B Basic Unit (Receiver) The MYW868B basic unit have to be installed near the control board. Avoid the installation in engine room, extremely hot places and near appliances generating...

External buzzer connection The external buzzer (not included) can be connected directly to the BZ terminal block or through the relay in case of high power consumption. The standard buzzer is also included and already connected. Port and Starboard Engine connection (Appendix) The MYW868B/CP remote control system is designed to control different engines with electronic commands specially with potentiometer type control heads. By the help of Resistor Adapters Pack many different electronic commands can be connected. a) Check all the Resistors Adapters and find the correct type. The type of...

ADJUSTING THE CONTROL VOLTAGE Note: • The control voltage adjustment have to be done after the complete system installation is finished. If the vessel is equipped with the engine’s electronic commands for which the Resistors Adapter is not included the following adjustments can be achieved: a) Insert the Resistor Adapter with trimmer potentiometers into the connector and spacer support. b) Connect the 3-wire cable in parallel with the port control head wires and another 3-wire cable in parallel with the starboard control head wires. Other end of cables push through the cable bushings and...

In case of special Bow and Stern thrusters control the bridges can be removed. (Please contact your dealer for more information.) STERN THRUSTER Joystick BOW THRUSTER Joystick To BOW THRUSTER Control To STERN THRUSTER Control Anchor Windlass connection The MYW868B/CP remote control system is also designed to control the vessels with equipped anchor windlass. The control wires have to be connected in paralell with anchor windlass control Switch wires. a) Connect the 3-wire cables in parallel with the switch wires. Other end of cables push through the cable bushings and connect to the...

Remote Control Box connection If the yacht is fitted with a fly-bridge an optional control unit, MYW868BE, can also be supplied for secondary engine commands. (Please contact your dealer for more information.) Antenna connection The MYW868B basic unit is designed with an internal antenna. But if the unit is installed near metallic parts or the receiver casing is covered with a metal cover or with another equipment with metal casing the additional antenna can be connected to the antenna connector. But first the connector cap have to be removed. If the unit is installed in the place closed...
