escription
D
GeoStamp+®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, GeoStamp+®can
also display a user defined message as well as real-time distance and bearing to a
user defined waypoint.
GeoStamp+®produces a self-generated screen if no video input source is available.
All NMEA 0183 compatible GPS receivers are supported.

IP Switch Configuration
D
GeoStamp+®comes configured for NTSC video format and 4,800 baud GPS
operation. To reconfigure these settings GeoStamp+®has 4 internal dip switches.
To access the dip switches disconnect all cables from the GeoStamp+®unit then
remove the 2 screws from the rear of the enclosure. After removing the rear panel
and bezel the circuit board will slide out.

gsLayout+ GPS Field Layout Utility
In addition to the GeoStamp+® built-in on-screen GPS field layout formats (e.g. standard,
top, etc) custom GPS field layout screens can be created using gsLayout+, a powerful
Windows PC based GPS field layout utility (see figure 2). The gsLayout+ utility
manages positioning and formatting of all the on-screen GPS fields. The user
configurable information is uploaded from the PC to the GeoStamp+® unit via a
RS-232 null modem cable. All uploaded information is stored in the GeoStamp+®
device's non-volatile memory.
gsLayout+ system requirements: Microsoft Windows 2000 operating system or
later with minimum 1024 x 768 video screen resolution and one RS-232 serial port
(or USB to RS-232 converter).
To install gsLayout+ insert the Intuitive Circuits Utilities disc and run setup.exe
located in the gsLayout+ folder. Follow the installation instructions.

O
After power is applied GeoStamp+®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.

Solution
• Verify power supply output (7.0 to 14 volts DC)
• Verify polarity of supply to GeoStamp+
• Verify internal fuse is good.
• 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)
• The attached GPS receiver does not have a
satellite fix but is communicating properly
with GeoStamp+
• Verify a clear view to the sky
• Wait up to 10 minutes for initial GPS receiver fix
• Verify that the GeoStamp+®"VIDEO IN" has
a noise free video signal
• Enable the Background Frame in the Display
