29 Chapter 6 General Specification 31 Introduction The ST50 Plus Multi is a powerful multifunction repeater that allows you to display many parameters transmitted onto the SeaTalk bus by other instruments As well as repeating live information the Multi is able to provide computed functions derived from data supplied by other SeaTalk instruments The following computed functions are available with a full SeaTalk system VMG True Wind Direction True Wrnd Speed Tack Course Distance Madeb Good and Course Made Good The ST50 Plus Multi also incorporates a security feature to protect instruments mounted in vulnerable areas such as the cockpit helm or mast Thank you for purchasing an Autohelm product May we take this opportunity to wish you years of trouble free operation2 Chapter 1 Control Head Installation 1lOmm 433in 3875mm 15in tl 11 Sing The ST50 Plus Multi is designed for above or below deck installation where it is l Easily read by the helmsman l Protected against physical damage l At least 230mm gin from a compass l At least 500mm 20in from radio receiving equipment l Accessible from behind for ease of installation and cable running Cation To prevent moisture forming on the display window the ST50 Plus Multi breathes through a small vent in the cable boss Therefore the control head must be sited where the rear case is protected from contact with water The rear case is ftied with a foam gasket to form a watertight seal between the instrument and the selected installation face Bracket Mounting The ST50 Plus Multi can as an alternative be bracket mounted using the Autohelm Mounting Kii Cat No D130 L 1 Cable boss 2 Fg studs 3 Thmb nuts 4 Gasket 212 Mounting Procedure Note Because the instrument breathes through the vent in the rear case 1 Make sure that the selected location is clean smooth and flat this bracket is for interior use only 2 Apply the selfadhesive template supplied to the selected location Flush Mounting and mark the centres for the futing

incorporates an antitheft feature called CODE Lock Designed to protect individual instruments or complete systems in vulnerable areas CODE Lock is a four digit number that you programme into the permanent memory of a selected master instrument Note A master instrument is a digital unit on which the code number can be entered and then if part of an integrated system transmitted to other ST50 Plus instruments0 e This facility means that should a CODE Locked instrument be removed from the vessel without your permission it cannot be operated without the four digit security number CODE Lock can be used in one of three modes ModelOff As it leaves the factory CODE Lock is set to off In this mode the instru ment will operate normally when it is switched on however the unit will not be protected by the antitheft feature Mode 2 CODE Lock OnceOnly Entry page 23 This mode is designed for systems with a digital ST50 Pius instrument in a safe belowdecks location This instrument can then be used as a master to enter the four digit code number and when the power is switched on automatically transmit the code to all the instruments in the system The advantage of this mode is that with the master safely below deck code entry via the keypad is a onceonly operation on installation Master Unit t Power Once CODE Lock is set the system operates normally as soon as the power is switched

Heading information is transmitted onto the SeaTalk bus by the instrument reading the fluxgate compass This can be the Autopilot or ST50 Steering compass which in either case should be set to display magnetic headings Magnetic Only t lf you want to display just magnetic headings on the multi set the Autopilot I CAL or ST50 Steering Compass to read magnetic and set variation on the Multi to zero this is the factory default True and Magnetic To display both true and magnetic headings set the Autopilot or ST50 VARATlON Steering Compass to read magnetic If available in the Autopilot calibration menu Variation should be set on the Autopilot Otherwise set variation on the Multi using WIND to increase and HDG decrease the displayed value Note When set to display true headings significant changes in local MULTI variation will after the true display as the fluxgate compass measures the magnetic heading If you want the Steering Compass or Autopilot to display true heading please contact your local distributor or the Autohelm t Product Support Department for advice I DEPTH Storing Variation To store variation press and hold DEPTH and LOG for 2 seconds Multi Depth Log HDG and Wind
