Section 1: Introduction
The XW-110 and XW-111 are easy t use wireless Wi-Fi temperature m nit ring and status alerting
devices. The XW-110 measures and rep rts temperature using a temperature pr be which c ntains a
precisi n digital sens r. The XW-111 m nit rs and rep rts the status f switch cl sure sens rs and
alarms. B th are ideal f r applicati ns where temperature r events must be m nit red and Ethernet
wiring is n t accessible r practical t install.
The m dules are p wered by an external wall transf rmer (5V DC), r by tw internal AA batteries. In
the case b th are installed, the XW-11x will use the wall transf rmer and aut matically switch t the
batteries in the event f a p wer failure. Only use batteries t pr vide backup p wer, r f r m des where
the web server is n t being used. If the internal web server is enabled in the XW-11x, the unit will need
t be p wered by an external wall transf rmer. S me c nfigurati ns c nsume m re p wer than thers
leading t s me scenari s where battery perati n is n t practical. F r example, measuring and
transmitting the temperature every five sec nds c uld result in depleting the batteries very quickly.
Having m re features enabled and/ r increased rep rting rate leads t l wer battery life.
The XW-11x can utilize ne f tw m des f perati n. The first being the "Stand-Al ne" m de which
makes the XW-11x a self-c ntained device that requires n additi nal servers r C ntr lByWeb devices.
In this m de the XW-11x pr ducts can pr vide live, real-time temperatures r input status directly t
users thr ugh web br wsers r the CBW M bile app. In additi n, the stand-al ne m de ffers the ability
t m nit r temperature r input status and send ut email alerts (which can be c nverted t text
message alerts) whenever an alarm c nditi n ccurs. The sec nd m de f perati n is "Slave" m de
which is used f r measuring and rep rting the temperature r input status t ther C ntr lByWeb
devices. In this m de, the XW-11x is n t directly accessible t the user. Temperature r input status is
transmitted t a server r an ther C ntr lByWeb device such as the X-600M c ntr ller which acts as a
"master.” The master device uses the inf rmati n pr vided by the XW-11x as it w uld use inf rmati n
c llected by any ther sens r.
A three-p siti n terminal strip pr vides c nnecti ns f r a temperature sens r r up t tw switch-cl sure
sens rs f r the XW-110 and XW-111 respectively. N ther cables, interfaces, r PC utility pr grams are
needed.
Tw user accessible push-butt n switches aid in pr visi ning the m dule. Press the “Access P int”
butt n anytime t active the access p int m de. With a PC r smart ph ne y u then c nnect t and
access the internal web server n matter what m de the unit is currently set t . Using the web server,
y u c nfigure the measurement interval, access p rt, name, and ther setup parameters. Alternatively,
add the XW-11x t an existing netw rk by pressing the “WPS” (Wi-Fi Pr tected Setup) butt n n b th
the XW-11x and n y ur access p int (i.e., r uter).

2.4 rovisioning
After making the sens r c nnecti ns and pr viding p wer, y u must pr visi n the XW-11x f r use n
y ur wireless netw rk. The g al is t c nfigure the XW-11x such that it can rec gnize and attach t y ur
Wi-Fi access p int. There are tw meth ds f r d ing this:
1. Access oint
By default, the XW-11x c mes up as a wireless access p int when p wered f r the first time. Pressing
the "access p int" push butt n any time als activates the access p int m de. It isn't really an access
p int because it will n t pr vide internet c nnectivity t y ur c mputer r smart ph ne, but it will appear
as an access p int meaning that y ur c mputer r smart ph ne will detect it as an access p int and
display it as such. When acting as an access p int, the XW-11x br adcasts an SSID f “XW110-
XXXXXX” r “XW111-XXXXXX” where XXXXXX are the last six digits f its MAC address.
With y ur wireless device (lapt p c mputer r smart ph ne) scan f r, and attach t the XW110 r XW111
wireless netw rk. Next, access the web server in the XW-11x using a web br wser. T access the setup
pages, enter the f ll wing URL in the address bar f y ur web br wser:
http://192.168.1.2/setup.html
After the page is requested, a passw rd pr mpt will appear. Enter the username and passw rd. The
username is admin and the passw rd is webrelay (passw rd is case sensitive). The next chapter
explains each f the setup tabs and screens. Use the WiFi Networks tab f r making the pr per settings
t all w the XW-11x t c nnect t y ur access p int.
Notes About Access Point Mode:
•Operates at full p wer and will c nsume large am unts f energy and drain batteries quickly. It is
rec mmended that y u use a wall-transf rmer t p wer the unit when perating in access p int
m de r c nfigure the XW-11x quickly.
•As an Access Point the XW-11x functi ns independently f ther wireless netw rks. It
br adcasts beac ns and services WiFi packet requests. In this m de, y ur c mputer r smart-
ph ne is "c nnected" directly with the XW-11x n a private netw rk and is NOT using an ther
wifi netw rk. Typically y u w uld use this f r c nfigurati n and n t f r n rmal perati n.
•The XW-11x has n hardware “rest re defaults” butt n, t prevent the installer fr m being l cked
ut, the default username (admin) and passw rd (webrelay) always w rk in the access p int
m de, even if the passw rd is changed. If the passw rd has changed via the assword tab,
b th the new passw rd and the webrelay passw rd will w rk.
•Only ne client (c mputer r smart-ph ne) can be c nnected t XW-11x at a time.
•SSID and passw rd cann t be cust mized ( nce again this m de is intended f r c nfigurati n
nly).
•Access p int is unsecured and pen.
2. W S (Wi-Fi rotected Setup)
The WPS Push button method, pr vides a simple meth d f r attaching the XW-11x t a wireless
netw rk with ut needing t use any setup pages. Alth ugh using this meth d t c nnect the XW-11x t
the netw rk is simple, y u will n t be able t access the XW-11x web server unless y u kn w the IP
address that was assigned by the DHCP sever (r uter) r unless mDNS services are available n y ur
device. F r this reas n, it is rec mmended that y u use this meth d f c nfigurati n nly when the XW-
11x units have been pre-c nfigured t perate in a n n-web-server m de r when y u have full access

t the DHCP server s y u can btain the IP address that was assigned.
T begin, press the WPS butt n n y ur wireless r uter r access-p int. Y u will generally have ab ut
tw minutes t c nnect wireless devices t the netw rk with WPS. N w rem ve the c ver f the XW-11x
and press the “WPS” push butt n. After a few sec nds, the XW-11x sh uld register itself with the r uter
r access-p int. If WPS fails, the XW-11x will aut matically enter the access p int m de.
The XW-11x will use DHCP t btain an IP address after a successful WPS ass ciati n. Additi nally, the
c nnecti n inf rmati n is als br adcast using mDNS. If y u need t access the XW-11x using its
internal web server y u will need t btain the IP address that was assigned t the XW-11x thr ugh y ur
DHCP server r r uter. Alternatively, if using an mDNS capable device, it may be accessed by entering
nce f the f ll wing int the address bar f y ur web br wser:

2.5 Application Examples
The XW-11x can be c nfigured f r many different applicati ns. Applicati ns which require l ng battery
life require careful planning and setup. Six examples are described bel w:
Greenhouse Temperature Example
Y u wish t activate a warning light and receive an email if the temperature in y ur greenh use
bec mes t l w r t high. N AC p wer is available.
M unt an XW-110 in a pr tected l cati n inside the greenh use. In this applicati n the XW-110 is
w rkable with batteries because transmissi ns are infrequent. Use the bare air temperature sens r
which c mes with the XW-110. Install a WebRelay™ r WebSwitch™ in y ur ffice and c nnect it t
y ur Ethernet netw rk. C nnect a warning light t the WebRelay. The WebRelay must be accessible
fr m y ur WiFi netw rk and be assigned a fixed IP address. Y ur WiFi netw rk must have adequate
c verage in the greenh use.
First, the XW-110 must be c nfigured t access y ur WiFi netw rk. If n netw rk pr files have been
c nfigured, the XW-110 will aut matically enter the access p int m de and y u can access the XW-110
directly with a c mputer r smart device with a wireless c nnecti n. If the XW-110 has been previ usly
c nfigured f r ther uses, press the Access P int butt n. Scan f r, and attach t the XW110-XXXXXX
wireless netw rk. Access the setup pages with the f ll wing URL: http://192.168.1.2/setup.html
F r this applicati n, c nfigure the XW-110 f r the stand-alone m de. C nfigure the XW-110 t c nnect
t y ur wireless netw rk. Navigate t the WiFi Netw rks tab and fill in the appr priate settings f r y ur

HTTP web server and av id using DHCP. Press the submit butt n at the b tt m f the page.
Navigate t the sens r tab. Enter the peri d with which the XW-110 sh uld m nit r the temperature as
well as the temperature thresh lds f r the alarm. T pr l ng the battery life set the update interval t 30
minutes r m re. Set the rem te relay acti n t Turn On. With this setting the relay will turn Off when the
temperature alarm c nditi n is n l nger met. Up n selecting an acti n, the rem te relay pti ns f r
specifying the IP address, p rt, relay number and ther pti ns will sh w. Enter the IP settings f r the
WebRelay. On the Email Option setting, select Send email on High and Low Alarm. Click the submit
butt n at the b tt m f the page.
Navigate t the email tab and enter the SMTP server settings as well as the username and passw rd (if
required). Y u may need t c ntact y ur email pr vider f r the exact settings t use. T pr vide
assurance the XW-110 is w rking, enable the Weekly Status Email pti n. Click the submit butt n at the
b tt m f the page.
Once all the appr priate settings have been applied, click n the Reb t butt n, the XW-110 will reb t
and begin l w p wer perati n. The XW-110 will n l nger br adcast an SSID and the web page will n
l nger be accessible. The XW-110 will peri dically awaken, measure the temperature and check f r an
alarm c nditi n. If an alarm ccurs it will c nnect t y ur WiFi access p int, activate the rem te relay
and send an email message. Once each week the XW-110 will send an email with temperature and
battery inf rmati n.
If y u wish t change the alarm settings the web server must be re enabled. T enable the web server
press and h ld the WPS butt n f r 10 sec nds. This will temp rarily enable the web-server f r 5 minutes
r until the unit is reb ted. Y u can access the c ntr l r setup pages during this time by entering the
