Serial GPS  
 

The GPS-44 is a high performance serial (RS232) GPS Receiver designed for permanent external installations in the marine environment.

This is a very tough device in an extremely slim design which can be pole mounted or flush mounted or rail-mounted (requires accessory).

Its standard NMEA output can be used to feed any compatible instruments as well as the PC (ie: DSC/GMDSS radio, RADAR, plotter etc).

    
       
   

Features

  
 

  • No driver is required
  • High-quality, slim, weatherproof design makes this an ideal GPS for permanent onboard installations
  • Supplied with 9-pin serial plug to connect straight into a serial COM port (or via a serial/usb converter), and bare wires for connecting direct to 12V or 24V DC ship's power supply

Notes

  
 


Installation
The GPS-44 can be flush mounted, pole or rail mounted.
  • Pole Mounting   The GPS base is fitted with standard diameter screw to fit inside a stainless steel pole. A funnel-shaped sleeve neatly covers the join.
  • Flush Mounting   Remove and discard the sleeve, and use strong marine sealant to glue the GPS directly to the surface.
  • Rail Mounting   The pictured accessory is required to mount the GPS antenna to a horizontal rail. This rail mounting accessory is a standard item and available from Marine Suppliers or Radio/Electronics stores.

If the cable must be cut to allow feeding through limited access areas (ie pushpit tubing) then it is highly advised to cut the 9-pin plug off the computer end of the cable.  Leave a six inch (15cm) "tail" on this plug for re-attachment, or purchase a new "9-pin male D plug" from a computer or electronics shop.
