Main page will be shown when you insert device address into address bar of your web browser. There you find actual measured values. Page with history graphs is shown when you click to tile with actual values. Access to device setup is possible via tile Settings .
9
General
Device name can be changed using item Device name . Measured values are stored into memory according History storage interval field. After changing of this interval all history values will be cleared. Changes must be confirmed by Apply settings button.
10
Network
Network parameters can be obtain automatically from DHCP server using option Obtain an IP address automatically . Static IP address is configurable via field IP address . It is not necessary setup Default gateway while you use device inside one subnet only. DNS server IP is required to set for proper function of DNS. Option Standard subnet mask sets network mask automatically according A, B or C network class. Subnet mask field must be set manually, when network with nonstandard range is used. Periodic restart interval enables to restart device after selected time since device start.
11
Alarm limits
For each measurement channel is possible to set upper and lower limits, time-delay for alarm activation and hysteresis for alarm clearing.
Example of setting the limit to the upper alarm limit:
12
In Point 1 the temperature exceeded the limit. From this time, the time-delay is counting.
Because at point 2 the temperature dropped below the limit value before the time delay expired, alarm was not set.
In Point 3 the temperature has risen over limit again. During the time-delay the value does not drop below the set limit, and therefore was in Point 4 caused alarm. At this moment were sent e-mails, traps and set alarm flag on website, SNMP and Modbus.
The alarm lasted up to Point 5, when the temperature dropped below the set hysteresis
(temperature limit – hysteresis). At this moment was active alarm cleared and e-mail sent.
When alarm occurs, alarm messages will be sent. In case of power failure or device reset
(e.g. changing the configuration) will new alarm state evaluated and new alarm messages will be sent.
Measuring
Page contains settings of the measuring part of the device. Settings can be saved only if jumper inside device is closed. Fields in this page are shown according device type.
It is possible set visibility of measured values on device LCD. Display can be switched off.
Units of measured and computed quantities are selectable by fields Temperature unit ,
Computed value and Atmospheric pressure unit . Devices without atmospheric pressure measurement have field Pressure value for computed values . Here is required to set pressure for calculation of computed quantities. Pressure compensation for altitude above sea-level is possible via Atmospheric pressure offset . This offset depends on current altitude. This value is added to measured atmospheric pressure, final value must be in range
300hPa to 1350hPa.
13
SOAP protocol
SOAP protocol can be enabled by option SOAP protocol enabled . Destination SOAP server can be set via SOAP server address . For setup of server port can be used option
SOAP server port . Device sends SOAP message according selected Sending interval .
Option Send SOAP message when alarm occurs sends message when an alarm on channel occurs or alarm is cleared. These SOAP messages are sent asynchronously to selected interval.
14
Email sending enabled option allows email features. It is necessary set address of the
SMTP server into SMTP server address field. Domain name for SMTP server can be used. Default port of the SMTP server can be changed using item SMTP server port .
SMTP authentication can be enabled using SMTP authentication option. When authentication is enabled Username and Password must be set.
For successfully email sending it is necessary insert Email sender address . This address is usually same as username of the SMTP authentication. Into fields Recipient 1 to
Recipient 3 it is possible set address of email recipients. Option Short email enable sending emails in short format. This format is usable when you need to forward emails into
SMS messages.
When option Alarm email repeat sending interval is enabled and there is active alarm on channel, then emails with actual values are sent repeatedly. Info email sending interval option enables sending emails at selected time interval. CSV history file can be sent together with the repeat/info emails. This feature can be enabled by Alarm and Info emails attachment option.
It is possible to test email function using button Apply and test . This button save a new settings and send a testing email immediately.
15

ModbusTCP and Syslog protocol settings are configurable via menu Protocols . Modbus server is enabled by default. Deactivation is possible via Modbus server enabled option.
Modbus port can be changed via Modbus port field. Syslog protocol can be enabled using item Syslog enabled . Syslog messages are sent to IP address of the Syslog server - field
Syslog server IP address .
16
SNMP
For reading values via SNMP it is necessary to know password - SNMP read community .
SNMP Trap can be delivered up to three IP address - IP address of the Trap recipient .
SNMP Traps are sent at alarm or error state on the channel. Trap feature can be enabled by option Trap enabled .
17
Time
Time synchronization with SNTP server can be enabled by Time synchronization enabled option. IP address of the SNTP is necessary to set into SNTP server IP address item. SNTP time is synchronized at UTC format, and due to be necessary set corresponding time offset - GSM offset [min] . Time is synchronized every 24 hours by default. Option NTP synchronization every hour decrease this synchronization interval to one hour.
18
WWW and security
Security features can be enabled by the Security enabled option. When security is enabled it is necessary to set administrator password. This password will be required for device settings. When secured access is required even to actual values reading it is possible to enable User account only for viewing enabled . Port of the www server can be changed from the default value 80 using filed WWW port . Web pages with actual values are refreshed according to Web refresh interval field.
Setup using TSensor software
TSensor software is an alternative to web configuration. Some less important parameters are configurable only by the TSensor software. TSensor software allows user adjustment of measured values.
Parameter MTU size can reduce size of the Ethernet frame. Lowering of this size can solve some communication problems mainly with Cisco network infrastructure.

SOAP
The device allows you to send currently measured values via SOAP v1.1
protocol. The device sends values in XML format to the web server. The advantage of this protocol is that communication is initialized by the device side. Due to it is not necessary use port forwarding. If the SOAP message cannot be delivered, warning message via SNMP Trap or
Syslog protocol is sent. SOAP message example:
<?xml version="1.0" encoding="utf-8"?>

Measuring error
The device allows time synchronization with NTP (SNTP) server. SNMP protocol version
3.0 is supported (RFC1305). Time synchronization is made every 24 hours. Time synchronization every hour can be enabled. For time synchronization it is necessary set IP address to the SNTP server. It is also possible set GMT offset for correct time zone. Time is used in graphs and history CSV files. Maximum jitter between two time synchronization is 90sec at 24 hours interval.
