output can be used for triggering relays, LEDs, or any device that will not require more then 200ma of
current.
You can change the state of the Digital Output port using the DIO diagnostic page (see
DSP
Diagnostics,
page
52
) or through an RPC method call (see
Digital I/O Methods
(WACI NX+ Only), page
118
).
DSP +5v Line
Provides a +5V power source. Use the +5V line as a reference, or to power small devices that feed back
into the ports.
DSP GROUND Line
To operate properly, the device connected to the input port must be connected to both the GND line of the
connector block as well as one of the four input ports.
LED Indicators for DSP Ports (1-4)
The LEDs indicate that the voltage on the port. The brightness of the LED is proportional to the voltage
level applied to the port. In the A/D and D/A modes the LEDs will vary their intensity while digital I/O
mode will be either on or off.

IR Ports
The four (4) IR ports on the WACI NX+ and (2) IR ports on the WACI NX Jr. are used to send infrared
commands to devices that can be controlled using a standard IR remote control. To control a device,
connect one of the IR emitters to the IR sensor of the device to be controlled. In addition the IR port can
be used a one way RS-232C (TX only) at rates up to 115k.
To program the WACI NX+ to send IR commands, you’ll need to download one of the device appropriate
.WIR files, or use the IR Learner to learn the remote for the device.
Use the IR Diagnostics page (see
Managing Learned Commands
, page
49
), an IR Action (see
IR Port
,
page
74
), or an RPC command (see
IR_SendCommand ( Port, Group, Command )
, page
125
) to send IR
commands out the IR ports.
IR Emitters
The IR Emitters are small cables with an IR Emitter at one end and a small audio style plug at the other.
The emitters plug into the IR ports. The emitter end attaches to the device to be controlled. When the
WACI is sending a command to the device through the emitter, the LED on the back of the emitter will
light up.
