WT100
(
RS485 Data Transparent Transmit Device
)
Introduction:
WT100 remote terminal device is a micro power wireless data transmission module. Based on LoRa spread
spectrum modulation technology, half duplex communication. There is a self-contained transceiver program
in the MCU. Users can realize transparent transmission of data (issued and received) without changing the
user data and protocol. Customers do not need to configure,easy to operate.
WT100 remote transmission terminal device can connect the RS485 serial port device or RS485 sensor to the
S281 gateway and the cloud, and transmit the devices or sensors data to the cloud. Can use many WT100 as
group networks. The gateway S281 can collect data of RS485 Sensors or devices which connected to WT100
via RS485. Commonly used in remote meter reading, access control systems, wireless data communications,
industrial data acquisition, wireless remote telemetry, security systems, robot control and other fields.
Features:
Wide voltage DC power supply, supports 3.3V ~ 24V.
Adopting efficient forward error correction coding technology and frequency hopping mechanism, strong
anti-interference ability and low error rate.
Communication parameters can be flexibly configured according to requirements.
Receive sensitivity up to -148dBm, maximum transmit power +20dBm
Interface anti-electromagnetic interference design to ensure that RS485 data is normal.
