6.The Identification Key must match that of the HQ Plus to which you are connecting.

7.Set the correct serial port settings. They should match the settings of the polling software, the ECR's communications port, and the HQ Plus modem port.

8.Connect the Ethernet port of the ST Plus to the store's LAN. Click "Write" and then click “Run”. You should see a time stamp and a “Connected to Unit: [device name]” message in the Message dialog window.

9.Select the mode of ST Plus operation: STOP, RUN, ACTIVATED.

Operating modes are as follows:

STOP. In this mode the ST Plus is not communicating to an HQ Plus. The ST Plus can be fully re-configured using the ST Config utility or the web page interface, and LAVA Ether Link Manager.
