Testing the connection between the POS-server and the POS-terminal

To test the connection of the POS-server to POS-terminals, use the HyperTerminal utility. This program is free and not included in Windows OS.

To test the POS-terminal connection, do the following:

1. Launch HyperTerminal on the POS-server. The utility interface window will open, and the Connection Description dialog box will appear.
   
2. In the Name field, enter a meaningful name for the connection, then click OK.
   

3. The Connection window opens. Select a network type in the Connect using drop-down list.
   

   Note.

    Select the connection type according to the POS-server to POS-terminal connection.

4. If TCP/IP (Winsock) interface type is selected, then select the local port number in the Port field and click OK.
   

   Note.

   An information box will appear with the following message: Unable to connect to port 2555. Click OK to close this box, then click Wait for a Call in the Call menu.
   

   

5. If the COM interface type is selected, click OK. In the COM Properties window that opens enter the required parameters and click OK.
   

   Note.

   The COM connection settings should meet the POS-terminal data transfer settings.
6. Start sending data from the POS-terminal to the POS-server
7. In case of successful connection, the data will be displayed in the HyperTerminal window.
   
8. In the main menu, select Call, then Disconnect to disconnect from the POS-terminal
9. To test the connection to all POS-terminals, select New connection in the File menu and repeat steps 2 to 8.
10. Close the HyperTerminal utility.

Testing POS-server connection to POS-terminals is complete.
