Chapter 4 Using PAS Software
The support PAS software is a configuration and data
acquisition tool that allows you to configure all of the EM920
features, monitor your meter on-line, retrieve recorded files
and view reports. PAS can communicate with your meter via
any communication interface installed in your meter,
including the embedded infrared port, serial ports, and the
Ethernet and wireless GSM/GPRS communications.
This chapter gives information on how to install and run PAS
on your computer, and how to prepare information for your
meter using PAS. See Chapter 5
Configuring the EM920 for
instructions on how to configure particular features in your
EM920. Refer to Chapters 7 and 8 for instructions on
retrieving data from your meter and viewing reports.
NOTE
PAS uses the Modbus RTU or Modbus TCP protocol for
communicating with the EM920. If you connect your PC to
the EM920 via a serial infrared or RS-232/RS-485 port,
ensure that the port is set to the Modbus RTU mode.
Software Installation
Installing PAS
You need PAS V1.4 Build 5 or higher to work with the EM920.
To install PAS on your PC:
1. Insert the installation CD supplied with your EM920
into CD drive.
2. Open My Computer on your Desktop.
3. Click on your CD drive icon, select the PAS directory,
and then double click on Setup (shown as an
Application type file).
4. Follow InstallShield® Wizard instructions on the
screen.
PAS is installed by default to the C:\Program Files\Pas folder.
If your user account rights do not allow writing to the
C:\Program Files\ folder, change the PAS default installation
folder to another folder to avoid possible ODBC security
problems when running PAS.
When installation is complete, the PAS icon appears on your
Desktop. Double click on the PAS icon to run PAS.
For general information on how to work with PAS, see the
“PAS Getting Started” guide supplied on the installation CD.
