G. P. O U T
G.P. OUT needs to be enabled before it will output signalling. See “Blue
Dot Menus for the Event Buttons” on page 88 for details on how to enable
output signalling.
If enabled, G.P. OUT will provide signalling each time a trigger event is
detected by the Analyzer. G.P. OUT’s signalling can be set to three different
formats - "Pulse High" provides a 16.66 ns (ground to +5V) signal, "Pulse
Low" a 16.66 ns (+5 V to ground) signal or "Toggle", a signal with an initial
High (+5V) state that alternates with each trigger event between continuous
High (+5 V) and continuous Low (Ground). "Pulse High" is the default
condition. To change the format, see “Enabling High Pulse, Low Pulse or
Pulse Toggle Signal Outputs” on page 88 for details.
Prototype Rework Area
The Breakout Board contains a prototype rework area for making custom
circuits for rapid development. The area consists of plated-through holes, 20
columns wide by 27 rows long. The top row of holes is connected to GND
and the bottom row is connected to +5V. The remaining holes are not
connected. Use the rework area to insert custom components and wire-wrap
their respective signal, power, and ground pins.
3.6 PC Connection
Use the USB cable provided to connect the host computer to the BTTracer
Analyzer.
3.7 Antenna Information
According to the Bluetooth™ specifications, Bluetooth™ Antennas should
be placed at least 10 cm apart. It is recommended that BTTracer be placed
at least 1 meter away from the nearest device in the piconet under
observation.
3.8 Analyzer PC Requirements
For an updated description of requirements, please refer to the readme file.
Note If installing BTTracer software on a Windows NT 4.0 system, you will need a
separate set of diskettes, which is available from CATC.
