rp_raj I need to interface 20 units of RS485 RTU Temperature And Humidity Transmitter Temperature Collector Sensor Module . But here the COM PORT address is limited to 12 only. How can I do it? How can I get proper documentation in English?

I managed to test the device with following settings: Modbus serial speed 9600, no parity, Modbus id 1. The device answers queries to Holding registers 0 and 1, which seems to represent temperature and relative humidity, respectively. The device fits into DIN rail. The only piece of documentation available is an instruction sheet in chinese. Documentation in English is needed!

This is first order. Normally I used to purchase from Amazon for the past 3 years.But you are selling somewhat competitive prices and somewhat less than amazon sellers. I was afraid to wait such a long time, because this goods are from foreign country. But I received all the goods without any problem. Your service is much appreciated. In future, I can order any goods without Thanks
