Quick Start Guide
S/PDIF Digital Input
This RCA female connector is a stereo digital input which conforms to the
S/PDIF (Sony/Philips Digital Interface) standard. The connec�ons are as follows:
Inner:
Signal
Outer: Ground
See the
web page on page 30 and the
web
page on page 43 for more details.
GPI/O
This 15 pin ‘D’ type socket provides 10 configurable general purpose inputs or
outputs and a voltage free switching relay contact. The connec�ons are as
follows:
Pin 1
GPIO Port 1
Pin 2
GPIO Port 2
Pin 3
GPIO Port 3
Pin 4
GPIO Port 4
Pin 5
GPIO Port 5
Pin 6
Relay – Normally Open Contact
Pin 7
Relay – Normally Closed Contact
Pin 8
Relay – Common
Pin 9
GPIO Port 6
Pin 10
GPIO Port 7
Pin 11
GPIO Port 8
Pin 12
GPIO Port 9
Pin 13
GPIO Port 10
Pin 14
Fused (200mA) +12VDC Supply
Pin 15
Ground
GPIO ports configured as an output are open collector type. GPIO inputs are
ac�ve low. See the
web page on page 47 for details on how to
configure the GPIO and relay se�ngs.
Ethernet 1GB & AoIP 1GB Network
Interfaces
These RJ45 connectors are the gigabit network ports. The upper connector
is the configura�on and control port and the lower connector is the audio
over IP (AoIP) port.
AoIP SFP Interface
This SFP (small form-factor pluggable) connector allows an alterna�ve
interface type to be used for the AoIP port, for example fibre. If a SFP
interface is used, the AoIP network port cannot be used at the same �me.
12V DC Input
This 4 pin connector allows an ex12V power supply to be used to
power the unit. When looking at the rear of the unit, the pin loca�ons and
connec�ons are as follows:
Loca�on
Connec�on
Pin 1
Upper Le�
+12V DC
Pin 2
Upper Right
+12V DC
Pin 3
Lower Le�
0V
Pin 4
Lower Right
0V
Both the 12V DC input and the mains AC input can be connected at the
same �me.
Mains Fuse
This 20mm x 5mm an�-surge mains fuse is rated at 2A.
Mains AC Input
This universally filtered IEC is the mains AC input power supply to the unit.
