HX-DPL Powerline General Guidelines

Note:

To ensure good audio quality, consider adding more HXII-DPL Powerline devices to your system.

Capacitance and resistance

Capacitance and resistance should be kept low. These increase with cable length and number of endpoints on the line. High capacitance and resistance causes fewer carrier frequencies to be available, which causes increased chance of data collisions as multiple devices try to use the same carrier frequencies, resulting in low data rates.

In these conditions, the user may experience audible clicks. As the collisions increase, audio may stutter intermittently and even drop.

Therefore, the use of low capacitance and low resistance cables is important when using extended cable lengths and more devices on the line.

Power

Low resistance cable (low AWG number) is best for power handling. Higher resistance cable can cause voltage drops on the powerline.

Crosstalk and Interference

Due to high frequencies (relative to analog transmission), Powerlines can be susceptible to crosstalk and interference. Maintaining cable shielding is important for Powerline installations, especially between Powerlines that originate from different Powerline Devices or HMS-4X Powerline Ports.
