PS-SEND Audio to IP Streaming Encoder 2
TOSLINK Unbalanced Digital Input
The stereo TOSlink optical connector is an
unbalanced S/PDIF input. This is typically used for
consumer digital audio.
GPIO General Purpose Inputs
An RJ45 connector is used for the GP inputs. The GPIs
are used to control the stream output and there are
six in total. Only one is used at any one time, which is
chosen from the webpage interface. The input can be
configured as active open or active closed.
A ground reference is also supplied on Pin 8. Simply
short the relevant input pin to the DGND pin through
a button or switch to register a press. The pinout for
the connector is as follows:
Pin 1:
GPI1
Pin 2:
GPI2
Pin 3:
GPI3
Pin 4:
GPI4
Pin 5:
GPI5
Pin 6:
GPI6
Pin 7:
N/C
Pin 8:
Digital Ground (DGND)
Ethernet Port
The 10/100Mbit ethernet port is a metallic RJ45 with
embedded LEDs which is used to connect the unit to
an IP network. Any standard CAT5 cable can be used.
There are two embedded indication LEDs which relay
the following information:
Green LED:
Illuminates permanently when a Link has
been established.
Yellow LED
: On power up, flashes periodically while
waiting for a connection. Once a connection is
established, it flashes whenever data is throughput.
The connector is wired as follows:
Pin 1:
Receive data+
Pin 2:
Transmit data+
Pin 3:
Transmit data+
Pin 6:
Receive data-
Pin 5:
Ground
All other pins are unused.
RS232 Serial Port
This is a 9 pin D-type socket which can be used to
update the firmware or send commands to the unit.
The connections are as follows:
Pin 2: Transmit data
Pin 3: Receive data
Pin 5: Ground
All other pins are unused.
IEC Power Plug & Fuse
The IEC power plug is a universal
filtered IEC, continuously rated 85-
264VAC @47-63Hz, max 10W.
The fuse socket is a where the
anti-surge fuse 1A 20 x 5mm fuse
is inserted. Please unplug the unit
whenever opening this cover.
