Chapter Introduction This chapter provides basic information about device. Before starting please read this manual carefully. The Web Sensor devices are designed for measurement of temperature, relative humidity and atmospheric pressure in air without aggressive substances. Measured quantities are according device type. Devices with relative humidity measurement can show one of computed quantities: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
It’s forbidden to use the device without the cover. Inside the device can be a dangerous voltage and may be risk of electric shock. Use only the appropriate power supply adapter according to manufacturer specifications and approved according to relevant standards. Make sure, that the adapter does not have damaged cables or covers.

Device does not support powering over Ethernet cable (PoE). PoE splitter must be used. Compatible PoE splitter can be purchased as optional accessories. Splitter must have 12V output with approximately 1W. Reliability of warning messages delivering (e-mail, trap, syslog), depends on actual availability of necessary network services.
Chapter Getting started Here you can find information necessary to put newly purchased equipment to operation. This procedure is only informative. What is needed for operation To install the unit you need to the following equipment. Before installation check if it’s available.
connect the power adapter 9 - 30V (e.g. 12V/200mA) LEDs on LAN connector should blink after connecting the power and LCD start showing measured values. Web Sensor EPD-T-INT, EPD-TRH-INT, EPD-TRHP-INT, EPD-P-INT, EPD- TRH(P), EPD-TRHP: Web Sensor EPD-T: Device settings ...
click to Change IP to set new address according to network administrator instructions. If your device is not listed, then click Help! My device wasn’t found! Then follow the instructions. MAC address is on product label. The device is factory set to IP 192.168.1.213. ...
Chapter 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.

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.

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.
Page 13
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.

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.

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.

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.

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.
Page 18
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].
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.
Factory defaults Factory defaults field set the device into factory configuration. Network parameters (IP address, Subnet mask, Gateway, DNS) are left without changes. Settings relating to measurement are not restored by factory defaults. Network parameters are changed while you close jumper and push button inside device during connecting power supply.

Chapter 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. For detailed description of protocols and application notes please contact your distributor. Website The device supports displaying of measured values, history graphs and configuration using web browser.
