OSD-GPS+ with Carrier Board

OSD-GPS+ is an on-screen composite video overlay device that overlays GPS (Global Positioning System) latitude, longitude, heading (track), speed, altitude, date, and time onto any incoming NTSC or PAL composite video source such as a color video camera. In addition to displaying GPS information, OSD-GPS+ can also display a user defined message as well as real-time distance and bearing to a user defined waypoint.

OSD-GPS+ produces a self-generated screen if no video input source is available. All NMEA 0183 compatible GPS receivers are supported.

Dip Switch Configuration:

OSD-GPS+ comes configured for NTSC video format and 4,800 baud GPS operation. Reconfigure these settings using the onboard dip switches. 

DIP #	Description
1&2	GPS RS-232 Baud Rate:            DIP 1     DIP 2     Baud            OFF       OFF        4,800            OFF       ON         9,600            ON        OFF       19,200            ON        ON        38,400
3	NTSC or PAL video format                     OFF = NTSC            ON = PAL
4	Firmware flash update            OFF = Normal operation            ON = Firmware flash mode

Note: DIP switch inputs are only checked during power-up. 

 

On-Screen Menu Configuration:

At any time press the "MENU" button to enter the on-screen menu configuration. The "UP”, “DOWN”, and “ENTER" buttons move the cursor and change the settings. All configuration information is stored in non-volatile memory so information is retained even with loss of power to OSD-GPS+.

Operation:

After power is applied OSD-GPS+ performs the following operations:

1. Establish communications with the attached GPS receiver
2. Wait for the GPS receiver fix with a minimum of 4 satellites
3. Update the on-screen fields after each valid NMEA GPRMC and GPGGA sentence is received from the GPS receiver
4. Check for “MENU”, “UP”, and “DOWN” button presses

At any time press the "MENU" button to enter the on-screen menu configuration.  

Status Icon:If the “Show Status” option is enabled (by default) the following icons may appear: 

Icon	Status
	No or invalid communications with the attached GPS receiver
	The attached GPS receiver does not have a satellite fix

 

“GPS FIX” LED:

The “GPS FIX” LED illuminates when the attached GPS receiver has a fix with a minimum of 4 satellites.  A GPS fix is required for on-screen GPS information to update.  

Distance and Bearing to Waypoint:
If the “Show Ranging” option is enabled then distance and bearing information from the current location to the user defined waypoint is displayed in real-time.At any time while there is a GPS fix press the “UP” button to set the current location as the waypoint.  Pressing the “DOWN” button will clear the waypoint.  It is not necessary to clear the waypoint before setting it again.

 

Trouble Shooting Tips:

Problem	Solution
Green Power LED will not illuminate OSD-GPS+ will not turn on	Verify power supply output (7.0 to 14 volts DC) Verify polarity of supply to OSD-GPS+
Blinking Clock icon No GPS information on-screen or fields do not update	No valid communications with the attached GPS receiver Verify GPS receiver is connected properly and has been configured to send NMEA 0183 data at the selected baud rate (4800 default)
Blinking Satellite Dish icon Yellow “GPS FIX” LED off No GPS information on-screen or fields do not update	The attached GPS receiver does not have a satellite fix but is communicating properly with OSD-GPS+ Verify a clear view to the sky Wait up to 10 minutes for initial GPS receiver fix
On-screen text is difficult to read	Verify that the OSD-GPS+ “VIDEO IN” has a noise free video signal Enable the Background Frame in the Display Options Menu
