WARRANTY INFORMATION WARRANTY INFORMATION Doppler Systems will repair or replace, at their option, any parts found to be defective in either materials or workmanship for a period of one year from the date of shipping. Defective parts must be returned for replacement. In the US, contact the factory, or overseas your local distributor, for advice about returning any defective parts or equipment.
Page 6 Doppler MPT Users Manual Revision D Chapter 1 1 1 1 Chapter Chapter Chapter INTRODUCTION INTRODUCTION INTRODUCTION INTRODUCTION The Series 7000 is a high performance radio direction finding system that operates using the synthetic Doppler principle in which a circular array of antennas are combined in a way that simulates a single element rotating in a circular path.
Page 7 Introduction Designed to work with standard commercial narrow band FM receivers • Highly configurable allowing for autonomous operation and multiple networking options • Master-Slave configuration allows up to 32 frequencies to be monitored simultaneously using • one antenna.

It is especially important that the coaxes used have the same length. Doppler Systems antennas DDF7061 and 7062 use the same magnetic mount base and cover the frequency ranges 88-136 and 136-500 MHz respectively. Cut the whips to resonance using the chart provided with the antennas and space them approximately 1/8 to 1/4 wavelength apart on the car’s roof.

For mobile operation in the 700-1000 MHz band, antenna DDF7064 should be mounted directly on top of the RF summer. This antenna provides an extended ground plane, a wind shroud, and four stub type antennas built into TNC connectors.

Page 40: Figure 32: Doppler Df Discover Will Display All Direction Finders Connected On A Lan
Doppler MPT Users Manual The Ethernet software in the DDF7001 ships with a DHCP client enabled, so if connected to a network that supports DHCP, the DDF7001 will obtain an IP address from the DHCP server. Once it has done this it begins broadcasting its IP address on the network as a UDP broadcast message on port 9007.
Page 41: Figure 34: Network Interface Setup In Windows
DDF7001 Processor Connections The DDF7001 is shipped with a default IP address of 10.0.0.100. If you are going to connect it directly to your computer you must set your computer TCP/IP properties as shown in Figure 34 below. Once it is connected you can use the web server or the MPT User Interface software to change the IP address and the IP port number.

Doppler MPT Users Manual The DDF7056 Yaw Rate Sensor is used to provide a faster update of the heading in mobile applications where the vehicle is performing frequent turns. This device outputs an NMEA message; however, its baud rate is 38.4 k. Therefore, the MPT User Interface software must be used to set the baud rate to 38.4 k prior to using the yaw rate sensor.

AUDIO INTERFACE AUDIO INTERFACE AUDIO INTERFACE AUDIO INTERFACE The DDF7001 digitizes the receiver audio and can stream it via UDP. Once a TCP/IP connection is made the controller sends a Stream Audio (0x0028) command to the DDF7001 signaling the DDF7001 as to which port to use to stream the audio. Once this command is received the DDF7001 will stream the audio when the audio level exceeds the audio squelch threshold.
