Analog to Digital converter (ADC) is used and the I2S signal is then fed into the IPAM 100 for encoding. For
all other sampling rates the audio signal is converted by the IPAM 100.
The connector J8 is a standard female USB socket connected directly to the IP Audio Module, intended for
plugging in external USB memory sticks.
The connector J5 is a standard RJ-45 socket connected trough an Ethernet magnetics circuit to the IP
Audio Modules primary network input.
This interface is an 10/100 Mbit, full / half duplex, auto negotiation Ethernet interface supporting TCP/IP,
UDP, RTP, DHCP and SNMP protocols and providing Barix AutoIP and IPzator features.
The connector J1 consist of two sockets, each with a detachable 6 pin screw terminal block plug.
The four inputs are connected trough parallel to serial converter circuit with the IP Audio module. These four
TTL level inputs are intended to be connected to push buttons or dry-contact closures only.
The four outputs are closing relays (normally open) and are connected through a shift register circuit to the
IP Audio Module.
The above mentioned shift register also drives the four I/O status LEDs.
These LEDs can be configured to display the states of the four inputs, the states of the four relays or to be
driven by a customized BCL application.
The very same shift register also features the signals needed to select the external ADC (SEL1) and to
switch the source of the digital audio input (SELINP).
The connector J7 consist of a socket and a detachable 2 pin screw terminal block plug allowing for a input
power supply range from 24 to 48 VDC ±20%.
This input is then fed into several power circuits to provide all internally needed voltages.
The Software reset push button, available on the devices front, is directly connected to the IP Audio Module.
Allows for resetting the device (brief push) and reverting to factory defaults (push approx. 10 sec.) as well as
additional functions depending on the firmware used.
The green and red status LEDs are directly connected to the IP Audio Module.
