Frequently Asked Questions
What is the maximum network distance for this module?
You can reach 1200 meters with proper cable. Use quality shielded twisted pair. Lower speeds allow longer distances.
Can this module connect to Modbus TCP networks?
No. The NW-BM85S485 only supports Modbus RTU. You need a separate gateway for TCP conversion.
How many devices can I connect to one module?
The module itself does not limit device count. The Modbus protocol supports up to 247 addresses per network segment.
What happens if I exceed the voltage range?
The module has overvoltage protection. However, consistent high voltage may damage internal components. Always stay within 10-30V DC.
From field experience, what improves communication stability?
Always use termination resistors at network ends. Proper grounding reduces noise issues. Keep communication cables away from power lines.
