Using the STEVAL-IPC004V1 for transactions

To perform the transaction, follow below steps.

Power up the board and the following message appears:

'Welcome to'

'STMicroelectronics'

After few seconds, the following menu shows modes to be selected on the LCD:

'Normal Mode'

'USB Mode'

'REPORT'

'GPRS DEMO'

'SELF DIAG'

'REG MODE"

Please wait for 3-4 minutes (for GPRS connectivity stabilization) press 'D' (enter) key to

select modes.

Note:

Don't leave the board in idle status for long time during a transaction. In fact, after a while

the board goes to screensaver mode and the transaction has to be deleted by pressing “C”

cancel key.

5.1

Starting transaction

Selecting “Normal Mode”, the transaction mode is automatically set and the following

message can be read on the LCD screen.

'New Transaction Started'

After few seconds, below message appears:

'Add Items using Keypad or Scanner'

5.2

Adding item to the transaction table

Currently the item information can be retrieved from the STEVAL-IPC004V1 using the bar

code assigned for each item. The current system supports up to 5000 types of item

information which is stored in the onboard memory. This can be easily customized.

An external bar code scanner is used to add item information. Alternatively, the bar code

info can be added using the keypad as well. Please make sure that bar code scanner is

connected to USB connector of the board before powering the board.

Once the bar code information is entered (for example: press button 3), the following

message appears:

'ITEM BARCODE'.
