LED Indicators for Serial Ports 1 & 2
There are two (2) sets of LEDs, one set for each serial port. Each set consists of two (2) red LEDs that
indicate activity on the pins.
When using RS-232 communications, the two LEDs indicate activity on the TX and RX 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 setup 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 setup page in order for it to properly work.

Network Interface
The NXT-700 has two (2) 10/100 Auto MDX Ethernet ports. LAN1 is POE (power over Ethernet)
capable. The Auto MDX allows the use of null or straight through LAN cables to the ports.
LAN Port
The NXT-700 may be connected to a network using a standard RJ-45 Ethernet cable in this port. Both
10Mb and 100Mb connections are supported.

LED Indicators
The green LED on the LAN port indicates that a network has been detected.
The yellow LED on the LAN port indicates that data is being transmitted or received through the port.
Relays
The Relays on the NXT-700 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, using an Event Manager “Relay Action”, or
through an RPC method call.
Relay Ports 1&2
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&2
Two red LEDs indicate activity for each Relay Port.

Digital I/O 1&2
Each I/O port is capable of being used in one of two different configurations; Digital Input, and Digital
Output. These modes of operation can be configured in the built in setup pages of the NXT-700 or via
RPC commands.
Digital Input
The Digital Input is used to read a digital voltage level. It can read 0V (=0) or 3V (=1). Higher voltages
are clamped to 3V. The digital input is perfect for applications requiring simple on/off detection such a
contact switch. By default the port is high impedance for the most flexibility. The setup page can also
allow a pull-up 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 or through an RPC method
call.
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
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 or through an RPC
method call.
I/O 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 two input ports.
LED Indicators for I/O Ports (1&2)
The LEDs indicate that the voltage is on the port. It will be either on (voltage present) or off (no voltage
or less than 1V).
IR Ports
The two (2) IR ports on the NXT-700 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 NXT-700 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. an IR Action, or an RPC command 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
NXT-700 is sending a command to the device through the emitter, the LED on the back of the emitter will
light up. Make certain if using 2 emitters on the same port that they are matched emitters for proper
operation. Do not mix brands of emitters when utilized on the same port as inconsitent operation may
occur.
LED Indicators for IR Ports
When an IR command is sent out an IR Port, the LED for that port is lit.
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 WACI World
website 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 NXT-700 to learn an IR command for
your remote. You’ll need to use the IR diagnostics page to learn the command.
IR Learner LED
The LED is lit during the learning process when an IR signal is detected on the IR sensor within the
NXT-700. 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.

VI. Expansion Hardware
The NXT-700 control system has the ability to expand its capabilities using the docking USB 2.0 Host
and USB 2.0 OTG connectors. This expansion bus is capable of high speed connection up to 400Mbps to
pass through small or large amounts of data for additional features like additional ports, Bluetooth Voice
Lift, WIFI, and much more. With the use of a USB Hub even more ports can be added. Always check
with the latest specification of the expansion device to see feature, power and docking requirements.
Specifications are subject to change without notice.

VIII. Mounting & Installation
The WMB-700 back box is sold separately from the NXT-700. The back box is designed to be mounted
into most drywall style installations of various thickness as well as podium wood panels.
The WMB-700 does have a top/bottom orientation which is shown in figure 1. If not mounted correctly
the panel will be upside down. An opening of approximately 7.72” (196mm) L x 5.75” (146mm) H will
allow the back box to snuggly fit into the wall. Once pushed into the opening, use the 4 supplied L
brackets to secure. This can be done from the inside of the box by holding the screw and inserting the L
into the T intersection towards the back of the WMB-700 until the entire L is on the outside of the unit
with the screw and washer on the inside of the unit. Note the notch at the end of the L bracket as it is used
to guide the bracket up and down and keeps it from spinning when tightening. Slide the L bracket
towards the front and tighten once snug. Do opposite corners first to make it easier the finish with the
remaining 2.
