Instructions for Using LR900 Series Telemetry Radio:
The default configuration of LR900 series telemetry radio is duplex, high-speed mode, and baud rate 57600.

1. Telemetry Radio Pairing
- As long as the parameters of the two arbitrary telemetry radios are the same, they can be automatically paired and communicated when they are powered on. The green light on the data transmission board stays on to indicate that the connection has been successfully achieved.
- Modules are configured by default. You can pair the modules as soon as you receive them, without having to modify the parameters. And we recommend that novices do not modify the parameters first, and should do some tests first.
- If you want to use several pairs of telemetry radios at the same time, you can modify the address parameters of the telemetry radios to different values.

2. Broadcast Mode
- When the telemetry radios are used for forwarding and receiving RTCM data on RTK equipment, they can be configured to broadcast mode, that is, one for TX and multiple radios for RX and one-way transmission. The base station is configured in broadcast-TX mode, and the mobile terminal is configured in broadcast-RX mode, and other parameters are the same.
- When the telemetry radios are configured in broadcast mode and are used to transmit RTK data, it is recommended to configure the radios in medium speed mode to maximize performance.
