LoRaWAN Products
YenGear LoRaWAN products connect serial equipment and field signals to industrial and building networks. Y501-L and Y511-L are indoor gateways; Y502-L is a serial DTU; Y503-2220-L is an I/O RTU.
Model Naming
The -L suffix identifies the LoRaWAN variant. Select the gateway's 8-channel or 16-channel configuration separately. In Y503-2220-L, the four digits give the DI / DO / AI / AO counts: 2 / 2 / 2 / 0. The analog-input count includes one voltage input (AV) and one current input (AI).
At a Glance
| Product image | Model | Product type | Interfaces or I/O | Radio configuration | 4G |
|---|---|---|---|---|---|
 | Y501-L | Indoor LoRaWAN gateway | Ethernet, Wi-Fi, RS485 | 8 or 16 channels | Optional |
| Y511-L | Edge LoRaWAN gateway | Ethernet, Wi-Fi, RS485 | 8 or 16 channels | Optional |
 | Y502-L | LoRaWAN serial DTU | Isolated RS485, isolated RS232 | Class A / Class C | — |
 | Y503-2220-L | LoRaWAN RTU | Isolated RS485, 2 DI, 2 DO, 2 AI | Class A / Class C | — |
Gateway Series
Both gateways include Ethernet, Wi-Fi, and RS485, with optional 4G backhaul. Local Network Server (NS) and Application Server (AS) services require the corresponding software option.
| Selection point | Y501-L | Y511-L |
|---|---|---|
| Basic role | Indoor LoRaWAN gateway and packet forwarder | Indoor LoRaWAN gateway with edge-side processing and application integration |
| LoRaWAN service | Packet forwarding to a remote NS; optional local NS/AS | Packet forwarding to a remote NS; optional local NS/AS |
| Field interface | RS485 hardware; local-service Modbus access depends on software | RS485 Modbus RTU server and Modbus TCP register mapping on compatible software |
| Application integration | Packet forwarding; optional local data services | MQTT, HTTP, TCP, WebSocket, JavaScript processing, and Modbus mapping with local-service software |
LoRaWAN End Device Series
Y502-L and Y503-2220-L send field data to a LoRaWAN gateway and receive downlink commands through the Network Server.
| Selection point | Y502-L | Y503-2220-L |
|---|---|---|
| Basic role | Serial DTU for PLCs, meters, data loggers, and serial sensors | Industrial RTU for distributed signal acquisition and remote control |
| Field interfaces | 1 isolated RS485 + 1 isolated RS232 | 1 isolated RS485; 2 DI, 2 DO, and 2 AI |
| Serial data | Modbus RTU or custom frames; ASCII/HEX command entry | Polling and transparent transport with configured commands and payload mapping |
| Analog input | None | 1 fixed 0–10 V input (AV) + 1 fixed 4–20 mA input (AI) |
| Digital output | None | 2 switched voltage outputs; on-state voltage follows the RTU supply |
| Analog output | None | None |
Channel Configurations
| Model | 8-channel configuration | 16-channel configuration |
|---|---|---|
| Y501-L | 8 RX / 1 TX | 16 RX / 2 TX |
| Y511-L | 8 RX / 1 TX | 16 RX / 2 TX |
RX counts receive channels; TX counts transmit paths. Device capacity depends on airtime, spreading factor, payload size, reporting interval, downlink traffic, and interference, rather than channel count alone.
Frequency Plans
Select the regional hardware variant for the gateway and each end device. Available plans differ by model.
| Regional plan | Y501-L / Y511-L | Y502-L | Y503-2220-L |
|---|---|---|---|
CN470 | Default | Reference plan | Reference plan |
EU433 | Available | Available | Available |
EU868 | Available | Available | Available |
AU915 | Available | Available | Available |
AS923 | Specify sub-plan | Specify sub-plan | Specify sub-plan |
US915 | Available | Available | Available |
IN865 | Available | Available | — |
RU864 | Available | Available | — |
“—” means the plan is unavailable for that model. Match the plan, channel group, and downlink settings across the gateway, Network Server, and end devices.
Network and Control Path
Serial equipment / field signals → Y502-L / Y503-2220-L → LoRaWAN gateway → Network Server → Application
The Network Server manages device activation, sessions, and downlink scheduling. It runs remotely or on a gateway with local NS/AS software. The application decodes data and creates commands; an application MQTT broker still requires a Network Server.
Class A devices receive downlinks after an uplink. Powered Class C devices listen almost continuously, except during transmission and the Class A receive-window sequence. Server scheduling and radio capacity affect response time in both classes. Test the complete path before setting reporting intervals and command timeouts. These products use a gateway and Network Server for communication.
Quick Selection Guide
- Choose Y501-L for indoor packet forwarding to a remote or optional local Network Server.
- Choose Y511-L for local data processing and application or Modbus integration with the required software options.
- Choose Y502-L for RS485 or RS232 equipment such as PLCs, meters, and serial sensors.
- Choose Y503-2220-L for direct digital and analog I/O. Its voltage outputs require loads compatible with the RTU supply and output rating.
- Specify the regional hardware variants, gateway channel count, backhaul, and local-service options when ordering.
