after changing IP address device is restarted and new IP address is assigned.
Restart of the device takes about 10 seconds.
connect to device using TSensor software and check the measured values. If Web
Sensors EPND-3T-POE and EPND-4S-POE values are not displayed, it’s necessary
to find probes using button Search probes (Find probes).
set the other parameters (alarm limits, SMTP server, etc.). Settings are saved
after click on button Save changes.
Checking functions
The last step is to check measured values on the device website. In the address bar of the web
browser, enter the device IP address. If the default IP address was not changed, then insert
http://192.168.1.213.
Displayed web page lists actual measured values. If the web pages are disabled, you can see
text Access denied. If the measured value exceeds the measurement range or probe is not
correctly installed, then is shown Error message. If the channel is switched off, the web site
displayed n/a instead of the value.

10
Device setup
This chapter describes basic device configuration. There is a
description of settings using web interface.
Setup using web interface
Device can be setup using web interface or TSensor software. Web interface can be managed
by the web browser. 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.
Chapter
3

11
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. 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 non-standard range is used. Periodic restart interval enables to restart device
after selected time since device start.

12
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:
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.

13
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. 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
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
Modbus a Syslog protocols
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.
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.
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. List of free
NTP servers is available at www.pool.ntp.org/en. SNTP time is synchronized at UTC format,

16
and due to be necessary set corresponding time offset - GMT 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.

17
Parameter MTU size can reduce size of the Ethernet frame. Lowering of this size can solve
some communication problems mainly with Cisco network infrastructure. TSensor software
can set offset of values at temperature probes. At TRHD-101 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, DNS) are left without changes.
Network parameters are changed while you press button at left side of device during power
supply connection. Factory defaults have no effect to user correction inside probe.

Communication protocols
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.
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 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 address of SMTP server. Domain address can be used as SMTP
server address too. For proper function of DNS is required to set DNS server IP address. SMTP
authentication is supported but SSL/STARTTLS 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 cannot be answered.
SNMP
Using SNMP protocol you can read actual measured values, alarm status and alarm
parameters. Via SNMP protocol is also possible to get last 1000 measured values from history
table. Writing via SNMP protocol is not supported. It is supported SNMPv1 protocol version
only. SNMP used UDP port 161. OID keys description can be found in the MIB table, which can
be obtained from device website or from your distributor. The password for reading is factory
set to public. Filed System location (OID 1.3.6.1.2.1.1.6 - sysLocation) is blank by default. The
changes can be made using web interface. Some SNMP manager software requires add .0 at
end of OID key (e.g.: .1.3.6.1.4.1.22626.1.5.2.1.2.0). OID keys:
