Communicating with ATPOL II
Introduction
The ATPOL II uses Bluetooth wireless communications to communicate with your PC. There are
several advantages to this method:
safety enhancement - since there are no metallic connections between the meter and your PC (part
of what allows your meter to be rated for 600 V Cat IV, the highest safety rating in the industry)
simplicity
– no communications cables are needed
reliability
– no cable, means no forgotten cables at the site and success in on-site setup and
download
reliability
– no physical connections are needed, hence physical connection problems are minimized
reliability
– the Bluetooth communications protocol provides for robust error-free communications
flexibility
– communicate with the meter from up to 30 feet away.
The disadvantages are:
the Bluetooth connection must first be made at the operating system level before the PSM
application can make the application-to-meter connection
your PC may not have Bluetooth capabilities, in which case you need to add a USB Bluetooth
adapter
turning your meter off and on may require re-establishing the Bluetooth connection at the operating
system level
the present implementation of Bluetooth communications in Windows is less straightforward than
USB or RS232 communications.
The next sections assume that a Bluetooth adapter is already installed in your PC. ATP sells an
adapter, but most Bluetooth-USB adapters will work. Follow the instructions that come with the adapter
to install the software.
Step 1: Connecting to the Meter at the Operating System Level
The ATPOL II meter and your PC must be turned on before the first step can occur. As soon as your
meter is on, the Bluetooth adapter in the meter is energized and can respond to broadcasts from your
PC’s Bluetooth adapter.
Different implementations of Bluetooth have different messages and screens for establishing
communications, but they all follow a similar flow. First the Bluetooth device is located, then it is paired,
and finally a serial communications channel is established with it.
Your Bluetooth software will probably have a Bluetooth icon shortcut on the desktop or at the
bottom of the screen. You will need to click on it and
click on something like “My Bluetooth
Devices”. Click on it and if you have previously communicated with your meter, an icon for
your meter will probably appear. It will have a name of “ATPOL II- nnnnn”, where “nnnnn” is
the serial number of your meter. If it does not appear, click on an option like
“Discover” to find any
Bluetooth devices that are in range. After as much as 1 minute, all Bluetooth devices that are detected
and available are displayed on the screen. An icon for your meter should be one of them.
Double click on the icon for your meter. If the meter has been “paired” with your computer, you will see
an icon of a serial cable connector labeled something like
“SPP Slave on ATPOL II-nnnnn”, where the
