XW110/XW111 WiFi™ Users Manual Introduction

Section 1: Introduction

The XW110 and XW111 are easy to use wireless Wi-Fi temperature monitoring and status alerting
devices. The XW-110 measures and reports temperature using a temperature probe which contains a
precision digital sensor. The XW-111 monitors and reports the status of switch closure sensors and
alarms. Both are ideal for applications where temperature or events must be monitored and Ethernet
wiring is not accessible or practical to install.

The modules are powered from either two internal AA batteries or a 5-volt wall transformer. In the case
both are connected, the XW11x will use the wall transformer and automatically switch to the batteries in
the event of a power failure. A three position terminal strip provides connections for a temperature
sensor or up to two switch closure sensors. Not other cables, interfaces or PC utility programs are
needed.

Two user accessible push button switches aid in provisioning the module. Press the “access point”
switch to active the access point mode. With a PC or smart phone you then connect to and access the
internal web server. Using the web server, you may configure the measurement interval, access port,
name and other setup parameters. Alternatively, press the WPS (Wi-Fi Protected Setup) switch on both
the XW11x and your access point to add the XW11x to an existing network.

1.1.3 Wireless Communication Notes

Due to the nature of wireless communications, transmission and reception of data can not be
guaranteed. Data may be delayed, have errors or be lost. Although delays or losses of data are rare
with a well constructed network, data can be lost due to interference, noise, reflections or other
environmental conditions. The XW11x should not be used in situations where failure to transmit or
receive data could result in damage to property, equipment, direct, indirect, consequential, or incidental
damage (including damage for loss of business profit, business interruption, loss of data, life, and the
like.)

Section 2: Installation and Setup

Begin by wiring the sensors to the green 3-terminal strip.

2.1.1 XW-110 Temperature Sensor Connections

The XW-110 works with a specific digital temperature sensor which is interchangeable and requires no
calibration. The sensors accuracy is +/-0.5°C (-10°C to +85°C). The sensor requires three connections
for communications and power (+5V, Ground, Data). The temperature sensor is available in several
configurations. For monitoring room temperature, the bare sensor can be connected directly to the
terminal strip. The rugged version is encapsulated in a stainless steel probe and can be used in
unprotected outdoor locations.

2.1.2 XW-111 Switch Closure Connections

The XW-111 can sense the state of up to two switch closure sensors. Sensors with switch closure
outputs include push buttons, magnetic door alarm switches, micro-switches, or any device which has a
relay or switch closure output. Both sensor inputs share the same GND connection. The XW-111 can be
configured for the alarm to be active when the switch is either open or closed. If possible, use switches
which are normally open (NO). When the switch contact is open no current flows thru the switch and the
longest battery life is achieved. When the switch is closed 17uA flows thru the switch.

The inputs use 3.3Volt logic and work with simple switches and relays. Do not connect the digital inputs
to a power source. The inputs will work with cable lengths up to 50-feet and should not be routed near
motors or AC wiring. The connections for two switches are shown:

2.1.3 Power

The XW-110 and XW-111 are powered from either a 5-volt DC wall adapter or two internal 1.5V “AA”
batteries. If the wall adapter is connected, no power is drawn from the batteries. If the external power
fails the module automatically switches to the internal batteries. No jumpers or switches are needed.
The wall adapter should be used for certain modes with high current demands such as: “Stand-Alone
mode” with HTTP server enabled, “Slave mode” with high reporting rates, or when “access point” is
active.

2.1.4 Provisioning

After making the sensor connections and providing power, you must provision the XW11x for use on your
wireless network. The goal is to configure the XW11x such that it can recognize and attach to your Wi-Fi
access point. There are two methods for doing this:

Internal Web Server

The web server requires an active Wi-Fi connection running at full power. It is recommended to use a
wall-transformer with this method or do the configuration quickly as this mode consumes large amounts
of energy. If this is the first time powering the device, it will automatically enumerate as an access-point,
other wise, you must remove the top cover and press the “access point” push button. The XW11x will
awaken and begin broadcasting as an access point. Its SSID is “TempModule-XXXXXX” or
“InputModule-XXXXXX” where XXXXXX are the last six digits of its MAC address. With your wireless
device (laptop computer or smart phone) scan for, and attach to the TempModule or InputModule
wireless network. Next, access the web server in the XW11x using a web browser. To access the setup
pages, enter the following URL in the address bar of your web browser:

http://192.168.1.2/setup.html

After the page is requested, a password prompt will appear. Enter the username and password. The
default username is admin and the default password is webrelay (password is case sensitive). The
following chapter explains each of the setup tabs and screens. Use the WiFi Networks tab for making
the proper settings to allow the XW11x to connect to your access point.

WPS (Wi-Fi Protected Setup)

The WPS Push button method, allows users a simple method for attaching the XW11x to a wireless
network without needing to use any setup pages. To begin, press the WPS button on your wireless router
or access-point. You will generally have about two minutes to connect wireless devices to the network
with WPS. Now remove the cover of the XW11x and press the “WPS” push button. After a few seconds,
the XW11x should register itself with the router or access-point. If the XW11x has not already been
configured, it will use DHCP to obtain an IP address. You will need to access the DHCP server, router, or
access-point to find the IP address it was assigned. Additionally, the connection information is also
broadcast using mDNS. Please note, that the XW11x web server is available with the default
configuration, but will not be if the device has been configured as a slave device or if it has been disabled
for the stand-alone mode.

Setup Pages XW110/XW111 WiFi™ Users Manual

Section 3: Setup Pages

The XW11x is configured using a web browser. To access the setup pages, enter the following URL in
the address bar of a web browser:

http://192.168.1.2/setup.html

If the XW11x has been added to a network using WPS, it will use DHCP and you will need to use the IP
address assigned to it. This can be found in the DHCP server, or by using mDNS. The mDNS name is
<NAME HERE>.

3.1 Main Tab – Stand Alone

This is the initial page that is displayed when setup.html is entered into the address bar of the browser. It
displays model and serial number information, and has navigation tabs which allow access to the
configuration and setup settings. The web pages and communication settings for the XW-110 and XW­111 are similar, pages with specific settings for the temperature or digital inputs are shown in the
following sections.

Page 8 Xytronix Research & Design, Inc.

XW110/XW111 WiFi™ Users Manual Setup Pages

The XW11x operates in two fundamental modes designated “Slave” and “Stand-alone”. Depending on
this setting the menu tabs change to reflect the relevant settings. Select “Slave” if the XW11x is to make
measurements and send data to a master device such as an X-600™. Select “Stand-Alone” if the
XW11x is to simply monitor the temperature/inputs and/or send e-mail alerts.

The Mode setting will not take effect until the XW11x is rebooted. To do this click the Reboot button after
making a change to the Mode.

Slave:

• In this low power mode the XW11x sleeps most of the time. It periodically awakens, makes
measurements, connects to a WiFi network and transmits data to a CBW device or other server.

• Use longer interval for long battery life.

• Intermittently connects to the wireless network as a Station. If the reporting interval is short, the

WR100 remains connected since the energy required to re-connect is greater than the energy
saved by disconnecting.

• No Emails are supported

• The Alert tab is suppressed, Remote Master tab is shown

• The internal web server is not accessible

Stand-Alone:

• Operates as a Station which allows the XW11x to be part of another wireless network.

• Periodically makes measurements and sends email alerts only when alarm conditions are

satisfied.

• Alarms and Emails are supported.

• The Alert tab is visible and Remote Master is suppressed.

• The internal web server is accessible at the option of the user. Enabling the internal web server

requires an active connection to the access point and is not feasible with battery operation.

Access Point:

• As an Access Point the XW11x functions independently of other wireless networks. It broadcasts
beacons and services WiFi packet requests.

• Connect to the XW11x access point with any WiFi enabled phone or laptop computer.

• Used for provisioning the XW11x.

• Periodically makes measurements and displays the data on its internal web page. Data is not

sent to other networks.

• Access Point works best when powered from a 5-volt DC wall adapter.

3.2 Main Tab – Slave

This tab is identical to the tab described above (Main Tab - Stand Alone) with the exception that the
Slave mode has been selected. With Slave selected, the Alert tab is replaced by the Remote Master
tab.

Select “Slave” if the XW11x is to make measurements and send data to a master device such as an X­600™. In this mode, the XW11x sleeps most of time conserving battery power. It periodically awakens,
makes simple measurements and transmits (pushes) the data to a remote server. Access the Remote
Master tab to select how often measurements are made and to which server the data is to be sent.

The Mode setting will not take effect until the XW11x is rebooted. To do this click the Reboot button after
making a change to the Mode.

In the low power Slave mode the web server is no longer accessible. To make subsequent changes you
must remove the top cover and press the “access point” push button to force the XW11x into a state
where you can connect to and access the internal web server again.

Use DHCP

This option allows DHCP to be enabled or disabled. If this option is set to Yes, the XW11x will wait for an
IP address from a DHCP server each time it is powered. The default setting is No (this is recommended
for most installations). If DHCP is set to Yes, the Network page must be submitted and the XW11x must
be rebooted before an IP address will be assigned. Once the XW11x is assigned an IP address by the
DHCP, the new IP address can be found through the clients list kept by the DHCP server. For most
instances, this is found on the local gateway or router. By not using DHCP, battery life is extended as the
device does not need energy for transmitting requests and receiving responses every time it connects to
the WiFi network.

Brief Notes About DHCP

All devices on an IP network require an IP address. This is a unique address that identifies each device
on the network. DHCP (Dynamic Host Control Protocol) is a mechanism that automatically assigns an IP
address to a computer (or other devices) when it is connected to a network. This eliminates the need to
manually enter the IP address. When a computer is connected to the network, another device on the
network called a DHCP server detects the presence of the computer and dynamically assigns the IP
address to that computer. On many small networks, the DHCP server is built into the router.

DHCP works well for "client" devices such as computers, but is not ideal for servers. This is because
servers usually don't initiate communications with other devices, but rather they wait for a request from
"clients." To make this request, the client must know the IP address of the server. If a server gets its IP
address dynamically, the IP address may not always be the same so client devices may not be able to
find the server. For this reason, servers usually use an IP address that is fixed and does not change. The
XW11x is a server and manual IP address assignment is usually recommended.

HTTP Server Enabled

This option can turn the internal HTTP web server on or off. Turning the web server off will allow the
device to make use of more power saving features. With the web server turned off, the device will be
allowed to disconnect from the WiFi network or at the very least service beacons selectively.

HTTP Port

The TCP port used for HTTP communications with the XW11x can be customized here. The default
setting for this field is 80, which is the standard HTTP port. It is recommended that the port be left
unchanged unless the user has an understanding of TCP/IP and ports.

3.4 Alerts & Email Tab

When configured as a Stand-Alone device this tab is visible. This page determines when alarm (alert)
events occur and what actions are to be taken. Up to three Email addresses can be assigned for alerts.
The same message is sent to each Email address. For Email notification to work, the XW11x must have
a properly configured network connection and a SMTP server must be defined.

Page 14 Xytronix Research & Design, Inc.

XW110/XW111 WiFi™ Users Manual Setup Pages

High Alarm

A high alarm is triggered when the temperature exceeds this set point.

Low Alarm

A low alarm occurs when the temperature is lower than this set point.

Deadband

The deadband (hysteresis) prevents conditions and alarms from triggering excessively when the
measurement value vacillates around the trigger point. With high alarms, the measurement must fall
below the high alarm point minus the dead band before the high alarm will be triggered again. Likewise
the deadband on the low alarm requires the measurement to rise above the low alarm point plus the
deadband before the low alarm will be triggered again.

For example, if the dead band is set to 0.5°C, and a high alarm is set at 13°C - the high alarm will occur
at 13°C; however, it will not turn off until the temperature drops below 12.5°C (13°C - 0.5°C).

Email Option

Simple email messages can be sent in response to alarm conditions. This parameter is used to specify
what alarm conditions, if any, will cause email messages to be sent. Email notifications will work only if
email is correctly setup in the following settings.

No Email Messages: No email messages will be sent due to alarm conditions.

Send Email on High Alarm: Email notifications will be sent due to a High Alarm condition.

Send Email on Low Alarm: Email notifications will be sent due to a Low Alarm condition.

Send Email on High and Low Alarm: Email notifications will be sent due to a High or Low Alarm condition.

Send Email on High, Low and Normal Alarm: Email notifications will be sent due to a High or Low alarm

condition or when Normal conditions are restored.

Email on Low Battery

When a low battery condition occurs an email message is sent to this address. To conserve already
meager energy resources, only one low battery message is sent.

3.5 Remote Master Tab

When configured as a Slave device this tab is visible. In this low power mode the XW11x periodically
awakens, makes simple measurements and transmits (pushes) the data to a remote server. This tab is
used to set how often measurements are made and to which server the data is to be sent. No alarms or
Emails are supported and the web server is inactive.

To save power in the Slave mode the XW11x normally disconnects from the access point. If the sleep
interval is less than 63-seconds the XW11x automatically remains connected since the energy required
to re-connect is greater than the energy saved by disconnecting.

Master Host/IP

The URL or IP address of the server you wish to send (push) data to.

Port Number

The TCP port used for communications with the remote server.

Push Type

Data is sent to the remote server with one of three HTTP protocols:

XCD Method (Xytronix Compact Data)

This method is used to send data to Xytronix devices such as the X-300. The CBW
method condenses the information into binary data to reduce the amount of energy
needed by the XW11x to transmit the information.
