CONNECTIONS AND CONTROLS

Power input port

Connect the Echo to the supplied universal mains AC power adaptor.
Using the supplied 2 pole screw block terminal connect white/black
wire to 12V and black wire to GND.
I/O ports
Echo has three I/O (Inputs/Outputs) available that can be configured
as either output or input. The ports are not potential free; you may
need external relays to prevent ground loops depending on your
application.
When used as outputs, the I/O ports are active low. When activated,
the I/O ports are tied to GND through a FET transistor, called open
drain/collector function.
When used as inputs the inputs are default HIGH and must be
connected to ground in order to change state to LOW.
RS-232
The RS-232 port is used for one- or two-way communication.
A two way port is used for devices where reply commands is used.
Connect the Echo as shown here.
RS-232/IR port
The RS-232/IR port is used for either one-way RS-232 or IR commu-
nication depending on the setup made in Biamp Project Designer.
Be aware that the port can't be used as RS-232 and IR port at the
same time.
