Serial port test: instrument data with 485 communication interface
Thread Content
I’m currently using a UPORT 1150 data cable to connect to the swirl vortex flow meter produced by Zhejiang Fuma Instrument Co., Ltd. The scanning software I’m using is a serial port testing tool, but I’m unable to establish a connection. I hope that fellow users can offer me some help; I want to scan certain data or addresses on this flow meter’s circuit board, as well as check whether the connections are correct. I appreciate any guidance from everyone.

Ensure that the communication line is functional and that the communication driver is working properly. What specific protocol is used for instrument communication? 485 is just an interface. I’ll check the manual specifically; there should be detailed explanations of the communication protocols. Specifically, set the communication address that matches the meter, the starting address for communication, the communication length, data type, etc., in accordance with the protocol
