Power Requirements
Power to the Inovonics receiver module is supplied by the N+ and N- terminals, and also supplies the onboard
Inovonics EchoStream receiver.
When the receiver module is connected via ethernet, module power is also supplied by the N+ and N- terminals.
If the receiver module is inserted into an existing section of the RS-485 module network, both module and network
power are supplied by the N+ and N- terminals.
Connection of the communications and network power should be performed according to the diagram shown.
It is important that the N+ network communications power be 12VDC supplied from an independent battery
backed power supply unit capable of supplying the required voltage to all devices on the RS-485 network.
The 12V N+ and N- communication input must be supplied from only
one
point. Connections from more than
one 12V supply may cause failure or damage to the unit or the device supplying network power.
