Figure 97 - Push-Pull Output Connection

CAUTION: For Matrix 300™ PoE models, the internal Digital Output

circuitry is not powered and supply power is not available to any Input/Output

devices (Vdc=0). Only input device signals can be accepted directly on the

M12 17-pin connector without power.

For these models, if it is necessary to use Input/Output devices, we recommend

connecting them through the CBX, which must be powered separately.
