Encrypt on-the-fly: Automatically encrypt data in real time to ensure data security. 3.2.3 Working principle and status of the base station:

Working principle:

wireless chip server 1. After Base Station power on, the ARM processor to start working, initialize the network chip and 2. After initialization, Base Station enters the network receiving state and waits for data from the 3. When the server has tag data, it sends the data to Base Station through the network. 4. Base Station receives the data and sends it to the corresponding tag by wireless Base station status 1. Power on: plug in the power supply and network cable, the base station screen display "----"

2. Online: computer running ESL software, the base station screen display "H-01"

3. Communicating: software sending data and the base station screen display "C--01"

4. Communication completed: the base station screen display changes from "C--01" back to "H-

01"

3.2.4 Base station control range:

Connection method: TCP/IP(Private Protocol) Control area: Circle with a radius of 13-15m (43-50 ft) (Area 530-706m (5705-7599ft)) 3.3 2.4GHz Electronic Shelf Label 3.3.1 Electronic Shelf Label Sizes & Parameters 3.3.2 2.4GHz Electronic Shelf Label Structure Electronic Shelf Label composition: front cover plate, e-ink display, PCBA board, battery, back cover plate.
