Speaker Terminals
These stereo speaker terminal blocks are for connecting a pair of 8
or 16ohm speakers. There are two connections each for left and right
speakers, positive terminals in red and a negative terminals in black. Please
ensure these are wired correctly. Generally the speaker cable will be

GPIO General Purpose Outputs
An RJ45 connector is used for the GP outputs.
There are 2 output relay contacts which switch
simultaneously and which can be triggered remotely
over IP from a connected PS-SEND unit. There is a
normally open and normally closed connection, per
relay connection, as well as a common for each. This
is configured using the web interface.
The pinout for the connector is as follows:
Pin 1: Not used
Pin 2: Digital Ground (DGND)
Pin 3: Relay Normally Open – connection 1
Pin 4: Relay Common – connection 1
Pin 5: Relay Normally Closed – connection 1
Pin 6: Relay Normally Closed – connection 2
Pin 7: Relay Common – connection 2
Pin 8: Relay Normally Open – connection 2
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
