Important DH-485 Network Planning Considerations
Carefully plan your network configuration before installing any hardware.
Some of the factors that can affect system performance are:
• amount of electrical noise, temperature, and humidity in the network
environment.
• number of devices on the network.
• connection and grounding quality in installation.
• amount of communication traffic on the network.
