Preface
This Quick Start Guide is designed to help new and intermediate users navigate and
perform common tasks with the Logic Analyzer. Despite its simple packaging and
interface, the Logic Analyzer is a sophisticated measurement and analysis tool. It is also
a highly sensitive electrical current sensing device. Users must carefully read
instructions and procedures pertaining to installation and operation. Any instrument
connected to the unit should be properly grounded. A pair of anti-static gloves is strongly
recommended when performing a task with the device. To ensure accuracy and
consistency of output data, use of the bundled components is strongly recommended.
User opinions are very important to us. Please contact our engineering team by
telephone, fax or email with your questions or feedback. Thank you for choosing the
Logic Analyzer.

R_O Read (Out)
T_O Trigger (Out)
S_O Start (Out)
Two pins used for grounding the Logic Analyzer with a
given external module to be analyzed.
When the Logic Analyzer is about to upload data from
memory to the PC, the R_O will send a Rising Edge
signal of DC3.3V. When the upload is finished, a
Falling Edge signal is sent.
When a trigger condition is established, the T_O will
send a Rising Edge signal of DC3.3V. When memory
is full, a Falling Edge signal is sent.
When a user initiates a sampling task by clicking the
RUN icon in the window or clicking the START button
on the device, the R_O will send a Rising Edge signal
of DC3.3V. When the Logic Analyzer finishes
uploading, a falling edge signal is sent.
