Prerequisites

Once the device is powered on, the user needs to perform the following steps sequentially.
1. Configure the network communication.
2. Install the updated ADK version in the device. It is recommended to restart the device after successful installation of ADK package.
3. Install SCA Solution package and followed by SCA Configuration package. Once installation is complete, it is recommended to restart the device once more to apply all the changes.
4. Once the device is ready with the required application, the preamble steps will be performed and followed by registering the device in Host. Following screen flows are added for detailing the process.

Additional Preamble Screens

Following are the additional preamble screens, which will be displayed based on different Host and its configuration:

Display Description
../_images/media_disp_scrn_addtl_preamb_MID.png Tap the text box for keyboard input to enter the Merchant ID.
../_images/media_disp_scrn_addtl_preamb_TID.png Tap the text box for keyboard input to enter the Terminal ID.
../_images/media_disp_scrn_addtl_preamb_laneID.png Tap the text box for keyboard input to enter the Lane ID.
../_images/media_disp_scrn_addtl_preamb_deviceID.png Tap the text box for keyboard input to enter the Device ID.
  

Note

MERCHANTSETTINGSREQD parameter should be enabled and MIDLENGTH, TIDLENGTH and LANEIDLENGTH parameters need to be configured to get successful preamble by entering MID, TID and LANEID details, when they are prompted during host registration process. Refer to Deployment Parameters for more details on this parameters.

  

Note

The next step in the preamble process takes place at the deployment center. It is noted here for information purposes only: Register the device in Host by sending the ADMIN request packet. Once the device is registered on Host, the application tries to register the device on the VSP server. Successful registrations on both servers is essential for the application to work in the customer environment processing transactions.

Prompt for Dummy Sale

The final step is to perform a dummy sale on the device, confirming the proper operation of the device in synchronization with gateway/processors. SCA prompts the user to move forward with the sale as shown above.
Continue with Insert, Tap or Swipe to prompt for the next step. Upon successful insert, tap or swipe, SCA will process a SALE transaction with Host. On successful SALE, SCA will then request Host to void the dummy transaction.
At the successful completion of the Preamble process, the Idle screen will display.
