RS485 grounding
We strongly recommend grounding the host IoT card. The RS485+ card has a special grounding
terminal. This increases the safety and resistance of the system to electrostatic discharge.

The use of shielded cables also improves safety and transmission quality. However, badly
connected or not connected shields of cables can only worsen the situation. Connect the shields
of bus cables to the ground only at one point.

Important!
Using high quality materials and taking care of the quality of the installation from
the very beginning, we can be sure that the system will function without the slightest
malfunction or interference for a long time, which is of great importance in bus systems and data
transmission.
