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.
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. 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 non standard range is
used. Periodic restart interval enables to restart device after selected time since device
start.

13
Alarm limits
For each measurement channel is possible to set upper and lower limits, time-delay for
alarm activation (0 –65535s) and hysteresis for alarm clearing.
Example of setting the limit to the upper alarm limit:
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 send.
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 send.

Channels
Channel can be enabled or disabled for measuring using item Enabled. Channel can be
renamed (max. 14 characters) and it is possible select unit of measured value according
connected probe type. When channel is not used, it is possible copy to it one of other
channels –option Clone channel. This option is not available at fully occupied device.
Find sensors button starts searching for connected probes. All changes must be
confirmed using Apply settings button. History values are cleared after changing of
channel settings.
SOAP protocol
SOAP protocol can be enabled by option SOAP protocol enabled. IP address of the
destination http server is configurable via SOAP server IP address filed. For setup of
destination server port can be used option SOAP server port. Target place of the http
server can be set via SOAP server target place. Device send 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.

15
Email
Email sending enabled option allows email features. It is necessary set address of the
SMTP as IP address into SMTP server IP address field. 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

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.
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.

IE-SNC-P85x1-11
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.
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. 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.
Parameter MTU size can reduce size of the Ethernet frame. Lowering of this size can
solve some communication problems mainly with Cisco network infrastructure. Sensor
software can set offset of values at temperature probes. At DSRH humidity probe is
possible set correction of the humidity and temperature.
Factory defaults
Factory defaults button set the device into factory configuration. Network parameters (IP
address, Subnet mask, Gateway) are left without changes.
Network parameters are changed while you close jumper inside the device. After jumper
closing it is necessary connect power supply. Factory defaults have no effect to user
correction inside probe.

Short introduction to communication protocols of the device. To use some
communication protocols is necessary software, which can use the protocol. This
software is not included. Detailed description of protocols and application notes
can be found in the manual appendix.
Website
The device supports displaying of measured values, history graphs and configuration using
web browser. History graphs are based on HTML5 canvas. Web browser must support this
feature for proper function of graphs. Firefox, Opera, Chrome or Internet Explorer 9 can
be used. If the device has IP address 192.168.1.213 type into your browser
http://192.168.1.213. Using TSensor software or web interface can be set automatic
webpages refresh in interval. The default value is 10sec. Actual measured values can be
obtained using XML file values.xml.
Values from history can be exported in CSV format. History storage interval can be set
using TSensor software or web interface. History is erased after every reboot of the device.
Reboot of the device is performed when the power supply is disconnected and also after
configuration change.
The device allows you to customize the design of web pages. Details of how to change the
design, you can find in the manual appendix. Manual appendix can be obtained from the
manufacturer’s website.
SMTP –sending e-mails
When measured values are over the set limits, the device allows send e-mail to a maximum
of 3 addresses. E-mail is send when alarm condition on the channel is cleared or a
measuring error occurs. It is possible to set repeat interval for email sending. For correct
sending of e-mails it is necessary to set IP address of SMTP server. SMTP authentication is
supported but SSL not. Standard SMTP port 25 is used by default. SMTP port can be
changed. Contact your network administrator to obtain configuration parameters of your
SMTP server. E-mail sent by the device can not be answered.
