1. PRODUCT DESCRIPTION BS1200
The BS1200 is a WIFI receiver station for the AREXX Multilogger system.
Like the BS510 USB and BS1000 Lan receivers, the BS1200 receives AREXX
sensor data via wireless transmission and sends these data via a WIFI
Network interface to a PC.
The WIFI link enables the BS1200 to send measured values wirelessly via the
TCP/IP protocol. This interface allows the transmission of Messenger
e-mails and HTTP requests as well. In addition to that, the built-in web
server can display recent measurement values. You will have wireless WIFI
access to this built-in web server with all other network items like a (Laptop)
PC, smartphones and tablets.
Contents of the package:
- BS-1200 WIFI multilogger receiver
- Power supply
- USB cable
- CD-ROM with all the necessary Software and manuals

2.2. Getting Started
The BS-1200 comes with an adapter and USB cable. The adapter connects
to the back 5V/±500mA. The USB cable can be used to connect to the
BS-1200 directly to a PC, then BS-1200 will operates exactly the same as a
BS510 receiver.
You can also use the USB cable to ash the new rmware for a new soft-
ware update.
3. First network connection
This paragraph describes how to connect the BS-1200 to your local Wi
network. For this we need the networkcong tool which can be found in the
tools menu of the logger software (be sure you have the latest version).
2.1. General settings
The BS1200 factory setting for Wi is:
security: none
ssid: ssid
Normally, you won’t have these settings, so we have to adjust the BS1200
to match your local Wi settings. The settings can be set with the network-
cong tool; you can start it from the ‘tools’ menu of the temperature logger
software.
In short, you scan for a network, select it and set its passphrase. After
pressing the write button a connection will made by the BS1200.
Connect the BS1200 via usb to a pc with the latest temperature logger soft-
ware. Start the networkcong tool; the following dialog will be displayed:
It shows empty network settings.
When you press the read button, you obtain
the current status of the bs1200.
You will nd the bs1200 is trying to connect
(to the ‘ssid’ network), but a timeout is
given since the attempt fails.

Note that some extra elds are displayed now concerning the Wi-connection.
(The tool detected that a Wi-enabled module is accessed).
Now we can scan for networks using the ‘scan’ button.
The status line will show the scan started, and after some seconds when the
scan has nished. The SSID eld is a combobox that will show a list with
available networks, including the current ssid (‘ssid’ for now).

Now the new info is saved in the BS1200 and it will initiate a new connection.
As indicated on the screen we switch back to the ‘Read’ tab and click on the
‘Read’ button again.
When the module is connected, it shows ‘Wi status: Connected’, and on top
the message ‘Network conguration valid’.
The obtained ipaddress and network name can be found on the display.
Normally, you can use the networkname in the url eld of your browser to
access the bs1200. (Please prepend ‘http://’ before the networkname). If that
is not working, the bs1200 should also be accessible by its ip address.

4. BS-1200 WEBSERVER
The obtained ipaddress and network name with the Networkcongtool can
be used to get access to the BS1200 webserver.
Normally, you can use the networkname in the url eld of your browser to
access the BS1200. (Please prepend ‘http://’ before the networkname). If
that is not working, the BS1200 should also be accessible by its ip address.
The embedded Web server contains several pages with recent data. There is
an administrative section available for various settings.
The BS1200 web server can be found at the address given by the network
name. Make sure that any rewall and/or browser blockades are removed
which are applicable to the BS1200.
The webbrowser start page shows for each sensor the most recent measu-
rement (Fig.7). The value presented is the latest sensor measurement. The
time display is formatted according to the default settings on the computer.
The RSSI column gives an indication of the strength of the received radio
signal.

Administration
We can reach the administrative part via the link at the top: ‘Admin’.
After completing the user id and password (default is admin/admin) we get
the Fig.8. screen. The current rmware version is listed in this screen. On
the left there is a column with a number of links we briey discuss:

E-Mail
This page determines the data of the e-mail server address that is
used to send Messenger records to an email address.
The ‘From eld’ denes the e-mail address of the sender that is used for the
transmission of the messenger e-mail. In some cases, the username and the
password must be entered. This can be done in the two lower elds. However,
in most cases the user name and the password are not required.
Sensors
The values of the incoming measurement are converted according to the sen-
sor denition le. This defenition le is an XML le that contains the required
parameter for the conversion. If new sensor types are added, the relevant
denition le can be uploaded here so that the BS-1200 can use these indi-
cations for the operation. When you submit an empty le eld, the default
internal denition le is used.

Messenger
The messenger is congured via a “Rule le” that is set up via a
so-called, `Rule Editor` and which contains one or more messenger
rules. These indications dene actions that are triggered as sson as
one or more conditions are met. The currently valid `Rule le` will
be marked as “current version”. Further details are given in the des-
cription Rule Editor. When you submit an empty le eld, the cur-
rent rule le is erased, and no rules are applied.
With the messenger software, you can send messages via e-mail and/or
http. This message may contain the most recent data from a sensor. It can
be set as an alarm and may be chosen in a way that only a meassege will
be send if it meets certain conditions, for example the temperature is below
0 degrees Celsius. (In the BS-1000 and TL-09 also an buzzer will go on).

Time server
When starting the BS-1200, and at regular intervals (if congured), the
time will be requested from an Internet time server. The clock in the
BS-1200 will be synchronized with this time.
The clock of the BS-1200 is powered by a button cell battery when the
station is switched off. Therefore the BS-1200 receiver will always register
new measurements data after switching on. This applies also for operation
without PC or network link.
The messenger function is based on the availability of the internal clock.
This clock uses the standard time (UTC). The adjustment of the time zone
is entered in minutes into the eld “timezone offset”. The time indicated on
the web pages of the BS-1200 is local time and based on the time parame-
ters of teh PC in charge of the browser.
Password
The default password is ‘admin’ and can be changed on this page.

Recent Events
The Recent Events screen shows a short summary of the most recent
events that the BS-1200 has recorded. The results of the executed rule
actions are indicated in lines per sensor. In addition to the executed rule
actions, other events such as access to web pages and DHCP actions are
recorded.

- 16 -
5. Rule Editor
The Rule-Editor is a tool for the creation of a rule-le that is used by the
BS-1200 to control the built-in Messenger functions. The Messenger allows the
start of one or more actions based on a incomming measurement value, if its
associated condition is met. The available actions are the transmission of an
e-mail, the transmission of a http request and the triggering of a built-in
buzzer.
You can dene multiple lines simultaneously. A rule always consists of a
condition and its associated action. If the measurement satises the condition,
the action will be executed. Evaluation of condition and action always takes
place within the context of the incoming measurement.
Folowwing parameters are required depending on the type of action:
For Email:
• Name of the rule
• Rule inhibition time
• Condition for the rule
• Email address
• Email subject
• Email message
For HTTP request:
• Name of thge rule
• Rule inhibition time
• Condition for the rule
• HTTP request type: GET, POST or PUT
• HTTP request url
• HTTP request message
For the buzzer:
• Name of the rule
• Rule inhibition time
• Condition of the rule
The inhibition time species the number of seconds that the rule remains
inactive after the rule action is performed.

- 17 -
Conditions
The condition is a logical expression that is evaluated within the context of
the received measurement. The value of the measurement and its associa-
ted attributes will be evaluated as variables.
The following variables are available:
Variable Description
$v Measurement value
$q sensor type 1 = temperature (°C), 3 = RV% (%), 5 = CO2 (ppm)
$i sensor
$r rssi value (dBm)
$h measurement time in hour
$m measurement time in minutes
$s measurement time in seconds
$Y measurement time the year
$M measurement time the month
$D measurement time the day
$S measurement time in seconds since 1-1-2000 UTC
$c measurement day of the week (0=sunday, 1=mondat, etc...)
$a(len) running average (len = length in seconds)
$b(len) running minimum (len = length in seconds)
$e(len) running maximum (len = length in seconds)
$p(dt) Previous value. If dt=0, then the previous measurement value is given,
otherwise, the interpolated value at the moment of dt seconds back in
time is given.
All time variables, except time $ S are UTC plus the time zone offset, is
given in the Time server setting page. The time variables $ S is in UTC.
The condition is structured like a logic expression. Following logical compa-
rison operators can be used for the denition: (<, <=, >, > =, <>, == and
!=), as well as the logical operators AND (&&), OR (| |), and NOT (!). Also
the arithmetic operations +, -, *, /, and% (modulo) can be used. Moreover
the expresion can be organised via the brackets “ „ and „ “.

- 18 -
Example
Expression Description
$v<10 results in true when the measurement falls
below the value 10.
$v<10 && $i=8297 results in true when the measurement of sensor
8297 falls below the value 10.
($v<-10 || $v>10)&&c==0 results in true when the measurement falss -10
or is bigger than 10, and the weekday is sunday.

- 19 -
The http message, email message and email subject text elds that can
contain variables. The value of a variable will be replaced by text when the
message text is set up.
The list of variables is:
Variabele Description
$v measuement value
$q sensor type 1 = temperature (°C), 3 = RV% (%), 5=CO2 (ppm)
$i sensor id number
$r rssi value (dBm)
$h measurement time in hour
$m measurement time in minutes
$s measurement time in seconds
$Y measurement time the year
$M measurement time the month
$D measurement time the day
$S measurement time in seconden since 1-1-2000 UTC
$w missing time of last measurement which could not be re-
directed to http server. Used for temp logger synchronization
$t time string measurement time in hh:mm:ss format
$d date string. measurement time in short date format
$p(dt) Previous value. If dt=0, then the previous measurement value is
given, otherwise, the interpolated value at the moment of dt seconds
back in time is given.
All time variables, except $w and $S, are in UTC plus the time zone offset
given in the Time Server Setup page. The time variables w$ and $S are in
UTC.
The HTTP request message is url-encoded per default. This means that
non-alphanumerical characters are converted into %hh-strings where „hh“
represents a hexadecimal gure. The lines ‘&&’ and ‘==’ are an exception:
these are converted into ‘&’, and ‘=’ respectively. The message for the HTTP
request is transmitted via the request header POST, or else added to the
URL of the GET request. In that case, the separating sign ‘?’ is added bet-
ween the URL and the message.

- 20 -
Example message:
id == i && $ value == $ v
In this example, a web server is programmed to decode the indicated string
in two parameters ‘id’ and ‘value’. This method allows to supply up-to-date
data from the BS1200 to a web page without a running a PC.
This mechanism is also used for the update of the temperature logger.
Flashed data
A special xml page is implemented to let other software retrieve data from
the BS1000. The page data.xml outputs ashed data within a given period.
The page is called with 4 parameters:
Parameter
name
Type Description
A timestamp Start of period; number of seconds since 1-1-2000
B timestamp End of period; number of seconds since 1-1-2000
C integer Sensor id
D integer Sensor type; 1=temperature, 3= RH%, 5=CO2
Example:
http://log77.lan/data.xml?A=327682224&B=327685203&C=4096&D=1
This call would result in the following dataset:
