Device Engineer and Fault Team: Program a card terminal

As a refresher for experienced couriers or for newcomers to the industry; the tech courier undertakes customer calls requiring programming of data, via the terminals keypad, into the specific fields identified in the call details by the terminal vendor. An example of call details is shown below in Photo 1.

At first glance the courier will notice fields have been blanked out. This has been done to hide the data recorded in those fields. Also, it can be seen there are two types of blanked out fields. The all white boxes are merely for hiding data the courier will use for identification purpose only. The white with red-outline boxes represent those field where the courier will enter specific programming.

Overall, the courier will note there are four separate blocks of data in the call details that will be explained.

1) The block marked FAULTY PTID represent the details of the faulty card terminal device allocated for collection from the customer.

2) The block marked SETUP PIN represent the fields a courier will input the access code to enter the programming level for the card terminal. Entering also the secure ID and encryption protocol to be used for the Wi-Fi signalling from/to the card terminal.

3) The block marked BILL MANAGER represent the fields a courier will input the unique channel and broadcast details to be used by the card terminal when actioning commands or receiving responses to and from the Wi-Fi network.

4) The block marked LOGIN ID represents the fields a courier will input log-in IDs and PINs into the card terminal in order the card terminal can validate itself as an authorised terminal to be using the Wi-Fi network.

Below are examples of some of the specific programming screens where data are actually entered by the courier. It should be noted that if any or all digits entered into the SSID, WPA Key, Terminal IP, Subnet Mask and/or IP Gateway are wrong then fundamentally the card terminal will be unable to communicate to the Wi-Fi network. Couriers should pay particular attention to ensuring accuracy in entering data supplied by the terminal vendor.
