The GPS system comprises of 24 satellites (operating globally 24 hours a day) grouped into six separate orbits. Up to 5 of the 24 satellites are tracked at any one time, and the difference between the unique signal from each satellite is used by the ST50 Plus GPS receiver to calculate your exact posiion. The ST50 Plus GPS and Navdata units also incorporate a security feature designed to protect instruments mounted in vulnerable areas, such as the cockpit or helm.

Therefore, the control head must be sited where the rear case is protected from contact with water. The rear case is fitted with a foam gasket to form a water-tight seal between the instrument and the selected installation face.

Make sure that the selected location is clean, smooth and flat. 2. Apply the self-adhesive template (supplied) to the selected location and mark the centres for the fixing studs (2) and the cable boss (1). 3. Drill two 4mm (5/32in) clearance holes for the fixing studs (2) through the bulkhead. Remove the template. 4. Cut the clearance hole for the cable boss (1) using a 50mm (2in) diameter cutter. 5. Screw the two fixing studs (2) into the control head. 6. Pass the SeaTalk cable and transducer tails through the cable-boss (11 clearance hole. 7. Assemble the control head to the bulkhead and secure from behind using the thumb nuts (31. I P baj =y k .a`w Chap&r 1: Control Head Installation 5 Bracket Mounting The ST50 Plus GPS/Navdata can, as an alternative, be bracket mounted using the Autohelm Mounting Kii (Catalogue No. D130). Note: Because the instrument breathes through the vent in the rear case, this bracket is for interior use only. flush Mounting A flush mounting kii is available for installations where a flush mount is required or more desirable. Full installation instructions are provided with the kii Katalogue No. D187). 6 S730 Plus GPS & Navdata Operation and htallation Handbook fi sb 1.3 Power Supply (stand-alone operation) 1. Connect the 2m (6ft.I power supply cable to the distribution panel. 2. Cut the cable to length and connect the red wire to the +12V terminal and screen to the OV terminal. 3. Cut back and insulate the yellow wire. 4. Protect the circuit with a 5A circuit breaker. Longer runs to the vessels power supply can be made using one of the SeaTalk Extension Cables. 1.4 Power Supply (SeaTalk operation) All instruments in a SeaTalk system receive power and information from the SeaTalk bus. Each instrument has two SeaTalk connectors (3 pin) on 150mm (6in) tails. To supply power and information to the instrument simply plug the tails from adjacent instruments into the ST50 GPS/ Navdata tails. I SeaTaik tails SeaTaik tails ",,,, 9 Chapter 1: Control Head Installation 7 :;?Y 1.5 Connection of Separated Instruments Separated SeaTalk connector it is cut instruments can be connected using one of the range of Extension Cables. These cables are supplied with a SeaTalk fitted to each end. A junction box can be used to join the cable if for easier routing or shortening. If preferred, any 2 core, screened cable conforming to the following specification may be used instead of the SeaTalk cable. l 22 AWG, 2 core screened cable with a minimum copper area of 0.5mm2. SE0 Plus GPS & Navdata Operation and Installation Handbook r'-` `G 1.6 Ring Connection Installations with a large number of instruments on a SeaTalk bus may require a second ringmain connection to the power supply breaker to prevent excessive voltage drops. Whether a second ring main is required can be determined from the following: CablerunuptolOm(33ft) Single connection: Second connection: Single connection: Second connection: 13 instruments maximum 26 instruments maximum 7 instruments maximum 13 instruments maximum Cablerunupto20m(66ft) The second ringmain should be connected to the spare lead on the last instrument in the chain and directed back to the circuit breaker. 1.7 Connection to SeaTalk Compatible Autopilots lf the installation includes a SeaTalk compatible Autopilot, ST50 Plus instruments may be connected to the SeaTalk bus at any point. No independent connection to the 12V power supply is necessary as the instruments receive power from the Autopilot course computer.

The position transducer should be connected to your SeaTalk system in one of the following ways: 1. Directly to the ST50 Plus GPSflavdata NMEA port. Red (Data in + ve) Blue (Data in - vel Power To other SeaTalk instruments or autopilot control units Navdata White (Data in + ve) Green (Data in - ve) ST50 Plus GPS & Navdata Operation and Installations Handbook ;?Q `1 w Note: When used with a Navcenter, the ST50 Plus Navdata/GPS can only be used in `Repeater ' mode (refer to Chapter 5, Calibration for details). Refer to the Navcenter handbook for accepted NMEA sentences. The Navdata is also capable of receiving navigation information directly from a Navstar 2000D Decca system. Connection is identical to NMEA but the instrument must be setup in Calibration to receive the special Navstar data format (refer to Chapter 5). ._ ._. . ,.--. 4 `, x %4+ Chapter 2: Fault Finding and Maintenance 11 Chiapter 2: Fault Finding and Maintenance 2.1 IFault Finding All Autohelm products are, prior to packing and shipping, subjected to comprehensive test and qualii assurance programmes.

This will not ham the instrument and can be cleared by increasing the illumination setting to Level 3. Chemical and abrasive materials must not be used to clean the ST50 Plus GPS/Navdata instrument; if it is dirty, clean with a soft, damp cloth. Transducer Refer to the Installation and Maintenance instructions supplied with the transducer. Cabling Examine all cables for chafing or damage to the outer shield and, where necessary, replace and resecure.
