547 +== 1.8 Example 8: This sketch is supposed to test Dragino RS485-BL (Modbus master), using an Arduino UNO as a Modbus slave. ==
548 +
549 +
550 +This sketch uses 4 registers: some of them can be set by Dragino with a command, another is used to store value from a DS18B20 temperature sensor, or a random generated number. All data is 16bit uint, but the sketch shows also how to represent booleans and negative numbers.
551 +
552 +In the next days I will be adding more documentation, but I think it already explains users how to build their own modbus sensor to pair with Dragino RS485-BL.

559 +== 1.9 Example 9: RS485-LN and ultrasonic flow meter transmission data ==
560 +
561 +
562 +It shows how to use RS485-LN to connect to an ultrasonic flow meter and read the data from the ultrasonic flow meter.
