The following sections will give you a good introduction to both getting up and running with PocketHHT, and the requirements for serial HART communications from your Windows Mobile PDA. If your primary concern is in the evaluation of PocketHHT as a configurator on your own PDA, then follow the simple steps outlined in the next section 'First Adventures in Field Device Configuration'. It shows you how easy it is to get up and running against the publicly visible fieldgate here at Open Field Communications.

If, however, you are interested in information on getting PocketHHT up and running as a Hand-Held configurator, then jump straight to section 'Advanced HART Hand-Held Terminal...'. Here you will find information on the necessary hardware required to transform your PDA into a HART configurator, as well as some hints to get you started with serial HART communications.

First Adventures in Field Device Configuration
If you are new to field device configurators or would like to take PocketHHT for an initial spin around the block, then follow these simple steps to get your PocketPC configuring the field transmitters on Open Field's very own Fieldgate FXA520.
	+		What You Will Need... a) a Mobile device running Windows Mobile 2002 or higher b) the PocketHHT installer from the Downloads page. c) a connection to the internet, either cradled or over WiFi
A Simple Evaluation of PocketHHT: Cradle your PocketPC and execute the PocketHHT Installer. Make sure you install both the binaries and the Device Library (DDs). Keep your PocketPC cradled, or alternately connect to the internet via WiFi. Execute PocketHHT. Select the 'Device >> Scan' menu option. Select 'Open Field' from the Connection drop-down selection list. This is a pre-configured connection to the FXA520 fieldgate in the OFC offices. Click the 'Scan' button. If you are correctly connected to the internet, PocketHHT should successfully locate a set of devices currently connected to the OFC fieldgate. Click on one of the devices to load the device descriptor and begin configuring. The device functional tree will appear. Click on a functional group to view its contents. Device Variables will become editable imediately as they are populated from the device. New values may be either free types or selected from a list depending on the variable type. Commit changes to variable settings using the green 'Commit' button at the bottom of the screen. Revert changes (prior to commit) using the red 'Rollback' button at the bottom of the screen. Locate a particular device variable using the blue 'Question Mark' button at the bottom of the screen. The locator uses a case-insensitive string search to find variable labels in function groups. Click on a search result to be taken directly to the variable. Terminate you session using the 'Device >> Disconnect' menu option. You may connect to another device (using 'Device >> Scan') or exit the application using the 'Device >> Exit' menu option.

Advanced HART Hand-Held Terminal...
Turning your Windows Mobile-based PDA into a serial HART configurator requires only the integration of the three pieces of hardware, and the installation of PocketHHT. What you end up with is a low-cost, functionally rich and extensable hand-held configurator.
	+		+		What You Will Need.. a) a Mobile device running Windows Mobile 2002 or higher b) a compact flash RS232(serial) or Bluetooth adapter c) a suitable HART RS232 or Bluetooth modem d) the PocketHHT installer from the Downloads page.
Getting Connected to a Local HART device: Cradle your PocketPC and execute the PocketHHT Installer. Make sure you install both the binaries and the Device Library (DDs). Keep your PocketPC cradled, or alternately connect to the internet via WiFi. Slot your compact Flash Serial I/O card into your PDA. Connect the RS232 connector of the CF card to your RS232 HART Modem. Connect two comms leads of the modem to the power terminals a suitable HART device. Remember that a suitable resistance may be needed to be placed between these connectors. Execute PocketHHT. You will need to establish the correct COM port indentifier that your Compact Flash card is providing. The default is 'COM1:'. If your modem is correctly connected to the device, then the easiest way to do this is to use the serial port locator: Select menu option 'View >> Configuration'. In the 'Connections' tab, click on the pre-configured 'Serial' connection. Select the 'Communications' tab. At the bottom of the screen, note the current setting for the serial port, and click the 'Locate Port' button to determine on which port the modem (and device) currently resides. Note: a HART device must be correctly connected, and reside on device index 0 for this to operate successfully. Alternately, you can cycle through the available comm port identifiers (starting at COM1:) and testing a device 'Scan' on that port. Once the port is established, select the 'Device >> Scan' menu option. Select 'Serial' from the 'Connection' drop-down list and click the 'Scan' button. You should see your device successfully located on the serial port. If the connection succeeds but no device is found, check your modem connections. You may also check that the searchable index range is wide enough for your device (if the configured index is not 0).
