RS-232/IR port
The RS-232/IR port (TX-2) is used for one-way RS232 or IR
communication depending on the setup made in Neets Project
Designer.
Be aware that the port can’t be used as RS232 and IR port at
the same time.
Connect the port as shown below.
NEB port
The EcHo Plus has a built-in NEB (Neets Extension Bus). This
port is used to add up to 2 NEB devices (e.g. two Keypads, two
Level Controls and one Expander).
Connect your NEB devices to this port with a cable not
exceeding 20 cm of length. PWR to PWR, NCL to NCL, NDA to
NDA and GND to GND.
If additional cable length is needed in your application, please
use the NEB extender to allow placement of the devices up
to 40 meters from the EcHo Plus. See the Neets website for
details on the NEB Extender.

When used as single IR port:
Connect the IR emitter to
TX-2 (white striped wire) and
GND, as shown above.
When used as RS-232
transmit port: Connect the
device to TX-1 and GND, as
shown above.
When used as dual IR port:
Connect the IR 1 emitter to
TX-2 (white striped wire) and
black wire on IR 1 emitter to
IR 2 emitter (white striped
wire), and black wire from IR
2 emitter to GND, as shown
above.
