III. Introduction
Welcome to the WACI world of powerful, non-proprietary, user-friendly control systems!
All puns aside, Aurora Multimedia has changed the way control systems are expected to behave. The
WACI (Web Access Control Interface, pronounced “wacky”) is one of the world's first standards-based,
non-platform-specific control systems. Not only does it work on just about any IP-based system, but it
can be developed on virtually any type of PC as well. The built-in web server, ftp file server, diagnostic
tools, and Event Manager allow the WACI to be free of proprietary tools and languages.
In addition to supporting standard languages such as HTML, DHTML, JAVA, FLASH, ASP, and Visual
Basic for creating control applications, Aurora Multimedia has provided powerful alternatives for the
non-programmer. For one, the built-in Event Manager runs server-side functions from web-based
interface without requiring a single line of code to be written. In addition, creating control interfaces with
Aurora's Flash-based program, called YIPI (Your IP Interface), is as easy as using a drawing program.
Furthermore, since the diagnostics and Event Manager are served up using a standard, non-proprietary
web server, any device equipped with a standard web browser, be it PC, Pocket PC, Palm, or Mac, is now
enabled to access your system.
The WACI does all this with a powerful 32 bit engine with 32 bit pipeline memory in a small box that can
fit just about anywhere. The power guarantees that small or large files can be processed without delay in
a real-time application with network traffic. Systems with less power and less memory bog down quickly
on server requests, but this is no problem for the WACI, which has enough power to support the smooth
performance of attractive, friendly user interfaces as well.
Aurora Multimedia did not stop at the software user interfaces to increase the serviceability and value of
the WACI. Other simple but effective innovations include C Type relays (normally open & closed
physically available), which allow creative use such as a switcher or to expand the amount of discrete
ports; RS-232 transmit from the IR to allow additional control from alternate ports; IR Input for just about
any IR remote to be used with the WACI NX; DSP (Digital Signal Processor) for A/D, D/A, Digital
Input, and Digital Output functions from a single port; Compact Flash for wireless and memory
functionality; NX-PANSION port to add additional modules for capabilities such as video streaming,
storage, touch panel interface and much more; and the built in temperature sensor, which allows
monitoring of the physical environment.
With the WACI NX+ and WACI NX Jr., Aurora Multimedia takes the control system industry to a new
era of easy-to-use, powerful, and cost-effective tools, paving the way for new possibilities in the way
systems are operated.

Detailed Hardware Descriptions
Power Indicator and LCD
Power Indicator and LCDPower Indicator and LCD
Power Indicator and LCD
A green power indicator is available on both the WACI NX+ and WACI NX Jr. The power indicator is lit
whenever power is applied to the WACI. The LED will stay solid if the system is ok. If a problem occurs
the advanced internal diagnostics will flash the LED to indicate the type of problem occurring. If the
LED is blink the WACI NX may need to be sent in for repair.
Power Adapter
The power adapter is included with the WACI NX. The 15 watts supplied is more then enough to power
the WACI NX as well as certain NX-PANSION add-on modules. Check with the NX_PANSION
module to make certain a higher wattage supply is not needed.
Power Port
The WACI NX is powered using the included Power Adapter. The smaller end of the Power Adapter is
plugged into this port. You should plug the Power Adapter into this port after the network cable has been
attached.

LED Indicators for Serial Ports 1 & 2
There are two (2) sets of LEDs, one set for each serial port. Each set consists of six (6) red LEDs that
indicate activity on the pins.
When using RS-232 communications, the six LEDs indicate activity on the (from top to bottom) TX, RX,
CTS, RTS, DTR, and DSR pins.
When using RS-422/485 communications, the LEDs indicate activity on the corresponding TX+, TX-,
RX+, and RX- pins.
RS-422 Operation:
When using RS-422 operation the RX+ and RX- should have a 120 Ohm resistor across the two pins.
Also, RS-422 operation must be selected in the diagnostics page in order for it to properly work.
RS-485 Operation:
When using the RS-485 operation the RX+ and TX+ should be tied together as well as the RX- and TX-.
There should be a 120 Ohm termination resistor across the two pins. Also, RS-485 operation must be
selected in the diagnostics page in order for it to properly work.

Relays (WACI NX+ Only)
(WACI NX+ Only) (WACI NX+ Only)
(WACI NX+ Only)
The Relays on the WACI NX+ have two connection types: N.O. = Normally Open, and N.C. = Normally
Closed. The “Normal” position is the state of the relay when it is not turned on (not energized). You can
turn the relays on and off using the relay diagnostic page (see Relay Diagnostics, page 51), using an
Event Manager “Relay Action” (see Relay, page 73), or through an RPC method call (see Relay Methods
(WACI NX+ Only), page 116). The Relay ports are available on the WACI NX+ only.
Relay Ports 1-4
Each port consists of 3 lines: NO (Normally Open), CP (Center Pole), NC (Normally Closed). Connect
the incoming wire to the CP connection, and the outgoing wire to either of the other two ports (NO or
NC). The outgoing port you choose depends on which type of connection you wish to consider “Normal”.

LED Indicators for Relay Ports 1-4
4 red LEDs indicate activity for each Relay Port.
DSP
DSPDSP
DSP (WACI NX+ Only)
(WACI NX+ Only) (WACI NX+ Only)
(WACI NX+ Only)
The WACI NX+ is the first of its kind to have a DSP coprocessor. Each DSP port is capable of being
used in one of four different configurations; A/D, D/A, Digital Input, and Digital Output. These modes of
operation can be configured in the built in setup pages of the WACI NX or via RPC commands.
A/D (Analog to Digital) Converter
The 12 bit A/D Converter can detect a range of voltage levels and convert them to a numeric value.
Therefore, the A/D Converter may be used for applications where states or commands are indicated by
variable voltage levels. A voltage of -5v applied to the port will produce a value of 0 when the port is
read. A voltage of 5v will generate a value of 4096. Voltage levels between -5v and 5v will produce a
proportional numeric value..
You can read the input from an A/D port using the DSP Diagnostics (see DSP Diagnostics, page 52), or
using an RPC call (see AD_ReadDigital ( Port ), page 121).
D/A (Digital to Analog) Converter
The 16 bit D/A Converter can output a range of voltage levels. Therefore, the D/A Converter may be used
for applications where varying output voltage ranges of -5v to +5v are required. The port will produce a
value of -5v when the port is set to 0 and 5v will with a value of 65536. Voltage levels between -5v and
5v can be sent by using a proportional numeric value.
You can set the output from a D/A port using the DSP Diagnostics (see DSP Diagnostics, page 52), or
using an RPC call.
Digital Input
The Digital Input is used to read a digital voltage level. It can read 0v (=0) or 5v (=1). The digital input I
perfect for applications requiring simple on/off detection such a contact switch. By default the port is
high impedance for the most flexibility. Using a resistor (10k for example) tied from the port to the 5v
will create a pull-up configuration. Doing the same but to ground will create a pull-down configuration.
If the port is left as is then the device connected to the digital input must supply the high and low
voltages.
You can see the state of the Digital Input 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).
Digital Output
The Digital Output is used as an open drain and can sink up to 200ma. Setting the port to 0 will leave sink
the input to ground. Setting the port as a 1 will put the port into a high impedance state. The digital

19
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
IR PortsIR Ports
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.

20
IR Ports
There are four IR ports on the WACI NX+ and 2 on the WACI NX Jr. They are located across the
Ethernet ports. Plug the IR Emitters into these ports.
LED Indicators for IR Ports
When an IR command is sent out an IR Port, the LED for that port is lit.
IR Learner
IR LearnerIR Learner
IR Learner
The IR Learner is used to learn the IR codes from a device’s remote control. It can read many different
types of remotes. If it has trouble with your remote, you may need to download from Aurora Multimedia
a .WIR file that is specific to the device.
IR Learner Port
Point your remote at the window on the lower right front of the WACI NX to learn an IR command for
your remote. You’ll need to use the IR diagnostics page to learn the command (see Learn IR Command,
page 47).
IR Learner LED
The LED is lit during the learning process when an IR signal is detected on the IR sensor within the
WACI NX. When the process is first started the LED will glow in and out slowly until a signal is
received. If the remote is too far away it will continue to glow slowly. The correct distance for the
strength of the signal is usually about 6” and will turn the LED solid when the proper distance is
achieved. If the remote is too close then the LED will blink fast.
