Determine the Serial Port

The installed driver will simulate a serial port on your computer. (The installation of the

driver will be introduced in next Chapter.) In order for the management software to

establish communication with the controller, the user must specify which com port has

been assigned to the simulated port on the computer. In order to determine the serial

port, please follow these steps:

1. After installing the driver and connecting the desktop reader to the computer via

USB, right click “My Computer”. Then click “Properties” in the context menu.

2. A dialog box will pop up (shown in the figure below). Open the hardware tab by

clicking “Hardware”. Next, click “Device Manager”.
