Test Environment

Figure 19 depicts a typical DC-BUS Test environment that allows testing the DMX250 devices in an emulated lab DC

powerline environment.

Figure 19 - DC-BUS Test environment

This test environment consists of two DMX250 evaluation boards (EVB), and two users' DMX-controllers. The DC-

powerline attenuator is optional.

The DC-powerline attenuator is used to test the communication in variable attenuation levels (0-61dB), emulating

a DC powerline environment. When connecting the EVB directly to a power supply, it is recommended to add in

serial to the power supply an inductor (>22uH) to avoid strong attenuation due to the power supply input filtering

capacitors.
