3.5 Speaker Interface
The male 2 pin connector
D
carries two pins, intended for a 8 Ohm speaker, are connected
directly to the D-class amplifier which is fed by a mono mixer, summing up the left and right
audio outputs of the IP Audio module. To achieve the highest sound power possible (5 Watt
RMS) use an 8 Ohm speaker. A reasonable performance can be achieved with an impedance
ranging from 4 to 32 Ohms.
To connect to a speaker use the supplied (b) orange, female 2 pin screw terminal block
(Weidmuller P/N 1690880000) and fix it to the device using the two built-in locking screws.
3.6 Network Interfaces
The female RJ-45 socket
E
is connected trough Ethernet magnetics circuits to the IP Audio
module. The switch attached must supply 48VDC “Power over Ethernet” (802.3af) or a PoE
injector must be used. The overall consumption is rated 15 Watts max. Power will be accepted
on pins 1,2 (Pa+) against pins 3,6 (Pa-) or alternatively on pins 4,5 (Pb+) against pins 7,8 (Pb-).
A standard network cable (Cat.5 or higher, not included) must be used to ensure proper
network and power functionality.
Status LEDs
The port features status LEDs (
F
).
The green LED shows the ports link status. On when the link is up, off when the link is down.
The yellow LED shows the ports network activity. On when any traffic* is seen on that port,
being it incoming or outgoing traffic. The yellow LED is off when there is no traffic on that port.
* Note:
This traffic could be generated by this device (outgoing), traffic not addressed to this
device but to any other device in the network (especially when daisy-chaining) or broadcasted
traffic (both incoming traffic but passed on) as well as traffic addressed to this device!
