1.0 INTRODUCTION

M. H. Corbin Portable Traffic Analyzer NC350™
adds Bluetooth capability to the NC300 product
family. The NC350 uses the same chargers, hard
covers, and data communications cables as the
NC300 and NC200 products, and also supports data
communications without a cable via the use of a
class 2 Bluetooth SPP connection to your computer.
Bluetooth communications requires that your
computer has a compatible Bluetooth radio installed,
either internally or via a USB Bluetooth dongle.
NOTE: To use the Bluetooth protocol with HDM
software, you must install HDM v3.0 or higher.

2.0 NC350 LED Indicators

The NC350 includes 3 LED indicators that are
exposed through the clear window on the end of the
unit. The LEDs indicate the status of the unit during
programming and after the completion of a traffic
study:
The Bluetooth protocol requires that each computer
which is to be used to communicate with the NC350
first go through a pairing process before that
computer can be used to program or download a
study. This is a security mechanism that prevents
unauthorized access to your NC350. The pairing
feature is only available when your NC350 is
plugged into the battery charger. When charging,
you should see the NC350 blue LED blink – this
indicates you can now pair your computer to the
NC350. The HDM software automatically will pair
your computer to the NC350 when you program a
study, read a study, or check the battery voltage of
your unit.
NOTE: Computers which do not pair with the
NC350 while the charger cable is connected will
not be able to program or read study data.
When your computer communicates to the NC350
using the Bluetooth protocol, the NC350 blue LED
will light continuously while it is connected.
A blinking GREEN LED indicates that a study has
completed and the study data is ready for download
to your computer. Once the study has been
downloaded, the GREEN LED will no longer blink.
