three. Alarm host 
(1) The wireless receiving antenna of the alarm host is used to receive the wireless alarm signal of the wireless alarm (card);
(2) The alarm host is equipped with a digital display for displaying the alarm target code;
(3) The USB interface data cable connects the alarm host and the monitoring computer to realize the data interaction between the alarm host and the monitoring computer;
(4) The host power supply connection provides a suitable working power supply for the wireless alarm host. The LA168 main unit operates with a 5V/500mA DC power supply.
(5) Install and use USB data cable at both ends of the first into the alarm host and monitor computer's USB interface, DC power supply power plug plug into the 220V socket, 5V connector into the host power input interface can be;
(6) Fixing of the alarm host - The alarm host can be directly pasted onto a smooth wall with high-quality double-sided adhesive, and it can be pressed tightly when pasting. The back of the LA168 type alarm host is set aside with 2 screw lock holes, which can be directly on the wall. Install two screws in advance, and then directly button up the LA168 alarm host.
(7) Note: The position of the fixed alarm host should be as far as possible to avoid obstacles, and the surrounding vision is particularly good. It is better not to hide too tightly so as not to affect the receiving effect. In use, the receiving antenna must be pulled to the longest. Get the best reception.
(8) After the Control Panel (through the USB cable) is connected to the monitoring computer and the normal power supply is connected, the relevant driver and monitoring software can be installed on the monitoring computer. The installation of monitoring software is described in the next section.
four. Monitoring computer and monitoring software
4.1 Installation of monitoring software under Windows XP (Note: similar installation methods under Windows 2000, 2003)
The first step: install the USB serial driver
(1) Connect the alarm host to the free usable USB slot of the monitoring computer through the USB conversion cable that is equipped with the device;
(2) At this point, the computer automatically prompts "Welcome to the Found New Hardware Wizard" and select "Install from list or specified location (Advanced)
(3) Find the "\\\\USB Serial Port Driver\\\\win" directory under the CD-ROM, click "OK", and follow the prompts to perform "Next" until completed 
(4) The system prompts again "Welcome to find a new hardware wizard", select the automatic installation, and follow the prompts to perform "Next" until completed 
(5) Under the "Port (COM and LPT)" in the "Device Manager", you can see one more "CP2101 USB TO UART Bridge Controller (COMx)". (If this flag does not appear, it indicates that the USB serial port is not installed successfully. , must be re-installed), the COMX is the monitoring computer and the alarm host communication interface, the monitoring software needs to set the COM port is the COM port, can be set automatically or manually. 
At this point, the USB serial driver is installed.
(The sound of '嘀-嘀-嘀' issued by the control panel during the installation process belongs to the alarm host and monitors the sound of the computer software not running. It can be ignored.)
Step Two: Install Monitoring Software
