IO Connectors
The TanGo has eight I/O (Inputs/Outputs) which can be configured as either
output or input. Each I/O is available for connection to a PIR (movement)
sensor, keyboard lock, relays or for other compatible uses. 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 (also called open drain/
collector function). Each I/O can draw up to 24VDC/500mA.
When used as inputs, the applied voltage must be below 1 VDC to be
accepted as LOW, and above 4 VDC (but below 24 VDC) to be accepted
as HIGH. The inputs are default HIGH and must be connected to ground in
order to change state.
NEB Port
The TanGo has a built-in NEB (Neets Extension Bus). This port is used to
add up to 5 NEB devices (e.g. two Keypads, two Level Controls and one
Expander). The NEB port includes an NEB extender that allows up to 40m
of separation between the TanGo and your NEB devices. However, you
MUST connect NEB extender module (Neets P/N 310-0005) at the end for
your NEB units.
The TanGo has a built-in NEB extender. Therefore, you need an
extender for all your NEB units as well.

When used as RS-232
transmit port: Connect the
device to T1, R1 and GND,
as shown here above.
When used as single IR port:
Connect the IR emitter to
T1 (white striped wire) and
GND, as shown above.
When used as dual IR port:
Connect the IR1 emitter to
T1 (white striped wire) and
black wire on IR1 emitter to
IR2 emitter (white striped
wire), and black wire from
IR2 emitter to GND, as
shown above.
