All Users of Pronto for Windows with Power Master Loggers.

Summary.

When communicating with a Power Master (or AP300 series) Logger from Pronto for Windows various settings must be correct for the communication to be successful. This application note lists the settings that most commonly cause problems.

Checklist for the Logger:

These notes apply directly to the PM3000 (other Loggers differ only slightly),
1) Check the baud rate that the Logger is set to communicate at, by performing the following steps.

1.    Power up the Logger by tapping the touch-screen (if running on battery tap the screen again within a couple of seconds to prevent the Logger shutting down to save battery.
2.    Once power-up is complete, click on Continue and then Next, the Main Menu screen will be displayed.
3.    Click on Configure and select Utilities from the list of options (you may need to scroll down the list).
4.    Check the Baud Rate. A rate of 115200 is recommended. See APPNOTE: Recommended_baud rates for different Loggers for more information.

Checklist for Pronto for Windows:

1) Check the serial port is correctly selected (also referred to as the Comm Port or COM port).

In Pronto 5.03 and later when selecting the serial port in the Logger Address Book you may click on Search and Pronto will scan your machine for Ports.
For guidance, on most computers the directly fitted serial ports are labeled COM1 and if a second port is present this will be COM2.
If you are using a Serial to USB convertor this could be a much higher numbered port such as COM6.

2) Check the baud rate matches that set in the Logger.

3) If using a Serial to USB convertor see APPNOTE: Using a USB to Serial converter with a Ranger Logger

4) If using a modem see APPNOTE: Setting up a Power Master Logger to operate over a modem
