When used as single IR port:
Connect the IR emitter to
TX-2 (striped wire) and GND,
as shown above.
Use Neets IR-Emitter
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 (striped wire) and black
wire on IR 1 emitter to IR 2
emitter (striped wire), and
black wire from IR 2 emitter
to GND, as shown above.
Use Neets IR-Emitter
All of the RS-232/IR ports can be configured in the
Neets Project Designer software either as RS-232
or as IR emitter.
Connect the port as shown below.
NEB port
The SieRRa II has a built-in NEB (Neets Exten-
sion Bus). This port is used to add up to 5 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. Connec-
tions are 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 SieRRa II. See the Neets website for
details on the NEB Extender.
