Baozi Intelligent Technology-Introduction of
AP Station
AP Station Electronic Price Tag Controller
ESL Base Station (AP), also known as Electronic Price Tag Controller, is an ESL communication base station independently opened by Baozi Intelligent Technology, which works in 2.4G wireless frequency band and is responsible for data transmission and information interaction between BL-AS sytem system and ESL. Baozi Intelligent Technology ESL Base Station is the third generation base station developed by Baozi Intelligent Technology, with more stable performance and faster transmission rate.
- Forwarding uplink data: connecting with BL-AS syetem through wired network, sending data such as price changing, stock and template switching to ESL;
- Forward downlink data: ESL base station works on the 2.4G protocol specification, and forwards ESL heartbeat and other information to BL-AS syestem platform based on ESL wireless protocol standard.

Product Appearance
On the front panel of the ESL base station (as shown in the following figure), there are power adapter interface, Ethernet interface, reset button, system indicator lights, USB interface, COM interface and four antennas.

Baozid ESL base station supports two power supply modes of adapter and POE, and users can choose different power supply modes according to specific use environment. The difference between the two power supply methods is whether to deploy power cables to the ESL base station, and other features and functions are exactly the same.
base station installation
In actual use, the base station should be installed in a higher position to achieve better transmission effect and coverage, as shown in the figure:

- Installation location of base station
Ideal environment for base station antenna: base station not close to roof, visible distance from base station antenna to price tag(Cargo) Except for shelves, but try to keep the shelving as small as possible) keep a distance of more than 10cm - Recommended distance of the base station It is recommended to install according to the covering radius of 15 meters
- ESL base station installation For ESL base station must be installed horizontally
Startup and Configuration
- Building Configuration Environment
Connecting the configuration terminal (PC) to the router with an Ethernet cable;
The router leads a network cable to the WAN port of the POE router;
Connecting the Ethernet port of the ESL base station with the LAN port of the POE router;
Powering up the router and the ESL base station;
Acquiring the IP address allocated by the ESL base station from the POE router end;
The configuration of communication parameters of ESL base station is completed by software on PC.
(ESL Base Station Configuration Network Diagram) - ESL Base Station Configuration
The default mode of ESL base station is DHCP mode. After the base station is connected to the router, it will be assigned an IP address. You can view the IP address obtained by the ESL base station through the configuration page of the POE router side. It is recommended that the IP address of the base station be set to a fixed IP address. - ESL Base Station Pre-Power Check Perform the following checks on the ESL base station prior to power-up:
① Is the power cord connected correctly?
② Whether the voltage and current of the power supply are consistent with the requirements of the ESL controller
③ Is the Ethernet cable connected correctly - Power-on start
After the ESL base station is powered on, the system is automatically started after 3 seconds, and during the starting process, when the ESL base station RF module
The indicator light is on, the indicator light display is always on, and the system starts normally at this time.
Base station characteristics
- Easy maintenance of base station
Newly installed base station: The actual operation of the store is not required. The headquarters or branch company will hand over the configuration of the base station to the store, and bind the MAC address of the new base station to the newly assigned store, and then use it after power-on.
Replace the base station: replace the MAC address of the new base station with the MAC address of the old base station, replace the new base station, and then power on. Replacement of base stations does not require manual participation of door stores. - Base station automatic routing
Electronic price tags move from one base station to another base station coverage, through the system routing strategy to relocate to the electronic price tag,
to achieve automatic routing. - Redundancy backup function The base station stores the data of each communication locally, and automatically initiates retransmission after the communication fails. The base station can also restore the previous price tag update record after unexpected power loss and restart
