If user has any question, please submit it back to customer center: http://h.usriot.com.
1.1.Product introduction
USR-LG220 is Gateway based on low-power consumption and WAN LoRa private protocol. LG220 can realize
networking between Gateway and LoRa module, communication between Gateway and server by USR private
protocol.
USR-LG220 supports one wired WAN interface and WiFi interface to realize various networking method. LoRa
private protocol can make communication more simple, more secure and more reliable. User can realize
communication by configuring Gateway and LoRa module without caring about protocol.

2.Product function
LG220 main function: Make LG220 Gateway and LoRa modules make up a communication network by USR
private protocol; realize data transmitting and receiving data from LoRa node, then LG220 will upload valid data to
server.
2.1.Work mode
USR-LG220 has two work modes:
Node active reporting mode
Polling waking mode
Note: In both two work modes, three conditions must be met to make LoRa module access Gateway network:
Gateway administration channel(channel 1) and LoRa module have same channel.
Gateway administration channel(channel 1) and LoRa module have same rate.
Gateway and LoRa module have same application ID.
2.2.1.Node active reporting mode
Node active reporting mode: After configuring LG220 into this mode, LoRa modules which access LG220 network
will enter active reporting mode. LG220 will return response automatically after receiving data from LoRa node
module and will also upload valid data to server.
In this mode, LG220 will enter listening status after powering on. Matched LoRa modules will send accessing
network information to LG220 automatically after powering on. After LG220 receiving these accessing
network information by administration channel(channel 1), LG220 will distribute these LoRa modules to
three communication channels(channel 2, 3, 4) in sequence, then return configuration data of accessing
network to these LoRa modules immediately and save these LoRa node modules information into database.
LoRa modules will change channel and rate automatically according to configuration data of accessing
network and match communication channel(channel 2, 3, 4), then report data to LG220 periodically
according to configuration.
User can configure LG220 into this mode by Web Server as follows(Three communication channels all need to
configured into this mode):

Technical Support: h.usriot.com
Figure 7 Node active reporting mode general settings
Application ID: In HEX format and user should configure this to be same as LoRa node module which access
to LG220 network.
Gateway ID: LG220 unique identification ID and can’t be changed.
Number of nodes: Reserved accessing nodes. Number of nodes should be equal or greater than actual
accessing node.
Adjacent Nodes Time slot: Idle time from last node finish transmission to current node start transmission. This
parameter is to prevent reporting data interference between adjacent node and supports at most 65535ms.
Figure 8 Node active reporting mode channel settings
Note: If user chooses ‘Update now’ and click ‘Save&Apply’, configuration will take effect after 10 seconds.
2.2.2.Polling waking mode
Polling waking mode: After configuring LG220 into this mode, LoRa modules which access LG220 network will
enter passive waking mode. LG220 will transmit lead code(Duration of lead code is same as waking period) to
Jinan USR IOT Technology Limited
www.usriot.com
USR-LG220 User Manual
Technical Support: h.usriot.com
wake up all LoRa node modules which connect to LG220 network according to Web Server configuration, then
LG220 will transmit data to LoRa node modules; after transmitting data, LG220 will transmit next data immediately
if LG220 receives response data from LoRa node modules, otherwise LG220 will transmit next data after receiving
time overtime.
After configuring LG220 into polling waking mode and configuring related parameters, LG220 will enter
listing status. When LoRa node module access LG220 network, LG220 will respond accessing network
information and save node information. When accessing network node is greater than 0 or accessing
network node has existed in database, LG220 will transmit waking data to wake up LoRa node module
periodically according to waking period, polling period and polling timeout time.
After receiving data from LG220, LoRa node module will take corresponding action and return related data to
achieve one time data transmission, then node will enter sleep mode and wait LG220 transmit next waking
data in next period. In this mode, user can configure at most 16 waking data.
User can configure LG220 into this mode by Web Server as follows(Three communication channels all need to
configured into this mode and same rate):
Figure 9 Polling waking mode general settings
Gateway Receive timeout: Timeout time to wait node return data after Gateway transmitting polling data and
support at most 65535ms.
Polling interval: Interval from finish polling all nodes to start next polling and support at most 10 days. Unit:
ms.
