April 5, 2015 HASSEB ETHERTEMP INSTRUCTIONS MANUAL VERSION 1.1 HASSEB ETHERTEMP hasseb EtherTemp is an easy to use data logger with Ethernet connection. The device implements a web browser user interface, which is used for reading the sensor data and for device configurations. The two Ethernet ports make it possible to connect another Ethernet device next to the EtherTemp device or even implement a redundant ring or parallel network topology. POWER The device is powered through USB port using the USB power supply provided. Relay 1 Relay 2
INSTALLING By default the device uses DHCP server to assign IP address. If you can’t find the assigned IP address from your router or other network device, you can connect the device to a Windows PC and use the EtherTemp.exe software. The basic network settings can be set up using the simple EtherTemp.exe software. The device implements a HID USB class, like mouse or keyboard, so no special drivers are required to connect the device to the PC. Figure 1. EtherTemp.exe software can be used to find out and set the network settings of the device. The EtherTemp.exe software is a very simple program to control the network settings of the device. If you have the DHCP enabled, the program shows you the host name and the assigned IP address, subnet mask, and default gateway. If you switch the DHCP off, you can manually set the parameters. When connected to PC, the device is also visible as a USB mass storage device. You can download the LOG.txt file, which includes the logging data. For big logging data files, using the USB connection is much faster than downloading the data using the Ethernet connection. WEB USER INTERFACE hasseb Inc. Vallikatu 8, 02650 Espoo, FINLAND [email protected] store.hasseb.fi April 5, 2015 HASSEB ETHERTEMP INSTRUCTIONS MANUAL VERSION 1.1 Writing the IP address of the EtherTemp device to the web browser, the index page will be opened. The present values for all the sensors attached to the device will be presented at the index page. If no sensor is found from a port, NaN (Not a Number) will be displayed as a value. The index page will also show the device time and the statuses of the two Ethernet ports of the device. Figure 2. The index page is displayed when the device IP address if written to the address field of your web browser. The device can be configured using the options page of the web user interface. A password is required to get an access to the device options. The default password is “password” without the quotation marks. It is highly recommended to change the default password to more secure one. Figure 3. A password is required to get an access to the options page. The default password in “password” without the quotation marks. hasseb Inc. Vallikatu 8, 02650 Espoo, FINLAND [email protected] store.hasseb.fi April 5, 2015 HASSEB ETHERTEMP INSTRUCTIONS MANUAL VERSION 1.1 Figure 4. Options page is accessible after writing the correct password. The present option values are loaded from the device when the option page opens. When making new settings, the “Submit” button have to be pressed to send the new values to the device. DEVICE CLOCK The device clock can be synchronized automatically using an NTP server or manually with the computer clock. The default NTP server is the server pool 0.pool.ntp.org, which will choose a random NTP server for you. SD CARD You can download or delete the log file using the web interface. The size of the log file is also shown. The size of the SD card delivered together with the device is 2 GB. It is possible to replace the card by opening the device enclosure and inserting a new FAT formatted SD card to the device. CHANGE PASSWORD It is highly recommended to change the default password (“password”). The password must be between 6 and 20 characters in length. Use letters and numbers only. SENSOR SETTINGS The logging interval can be between 10 and 9999 seconds. Each of the four ports can have a unique name. This name is displayed on the main page. hasseb Inc. Vallikatu 8, 02650 Espoo, FINLAND [email protected] store.hasseb.fi April 5, 2015 HASSEB ETHERTEMP INSTRUCTIONS MANUAL VERSION 1.1 There are three different type of sensors available; DS18B20, DHT11, and DHT22. It is also possible to select the temperature unit between degree Celsius and Fahrenheit. Figure 5. Sensor settings. NETWORK SETTINGS The hostname, IP address, subnet mask, and default gateway can be set using the web interface or by using the provide EtherTemp.exe software. The DHCP can also be enabled or disabled. By default the device uses DHCP to assign the network settings. The default hostname for the device is EtherTemp. RELAY CONTROL The device has two relays which can be controlled manually or automatically based on the port 1 and 2 sensor values. The relays can be used for example to raise alarm signals when temperature limit is reached or to control door locks through web browser. hasseb Inc.

E‐MAIL SETTINGS The device can send an e‐mail message when the relay state has changed due to an automatic relay control. The e‐mail subject can be changed but the e‐mail body is fixed and will always include only the sensor name and the sensor value. RESET FACTORY DEFAULTS Reset the factory default settings. SYSTEM INTEGRATION The device can be configured and the sensor valued read by using standard http GET and POST requests. The present sensor values can be read from the EtherTemp device using a simple http GET request GET /get_sensor_values. The responded sensor data is tab delimited text and the different sensor values are separated with a semicolon. For example the response for four DS18B20 sensors are 22.0 C;23.0 C;21.5 C;22.2 C; where the separator between the number and the unit is a tabulator. The logging file can be downloaded using a GET /LOG.txt request. The logging file can be deleted with a post request POST /delete_log_file , where the password is send as a parameter PW=password . LOGGING FILE hasseb Inc. Vallikatu 8, 02650 Espoo, FINLAND [email protected] store.hasseb.fi April 5, 2015 HASSEB ETHERTEMP INSTRUCTIONS MANUAL VERSION 1.1 The logging data is written to the text file LOG.txt. Each reading line starts with a date time stamp following the sensor data for all the four sensors. If no sensor is present, the value is NaN. The data in each line is tab separated and terminated with a carrier return and a new line feed. The date time stamp is formatted in ISO 8061 format as YYMMDDThhmmss, where YY is the year MM is the month DD is the day T is a separator hh is the hour mm is the minute ss is the second. LEDS The device has a multicolor LED to indicate the status of the device. Green, 50 ms on/10s off: The device is working properly and logging the data according to the settings. Red 1 s on/1 s off: Error, the device will reboot automatically. RESET FACTORY DEFAULTS If something goes wrong with the network settings and you cannot access the device anymore through the network, you can reset the factory defaults in three ways. The default network configuration is DHCP on. 1.

3.
Using the Windows software EtherTemp.exe. Using the web interface (maybe not possible in the case of a network fail). Using the button F1 on the circuit board. To access the button you need to open the enclosure and pull out the circuit board. The device needs to be switched on when pressing the button. BACK UP BATTERY If you do not use an NTP server to synchronize the device clock, the time information will be lost in the case of blackout. To prevent this, you can insert a type CR1220 coin cell battery to the device. The battery holder is accessible by opening the enclosure and pulling the circuit board out. hasseb Inc.
