USER MANUAL IP-52 AREXX

Starting up - First please read this complete manual before you continue. - More manuals can be found on the CD and in our Multilogger Software HELP FUNCTION. - Install the software, please refer to the manual on the CD-ROM! Always check on www.arexx.com if you have the latest software version at hand. - Connect the USB receiver to the computer. - Start the program. - Insert batteries in the sensors. - Consult the help function of the software if you have further questions. Important information about the MULTILOGGER Logger - The receiver which is connected to the computer receives the signals coming from the sensors. - The computer can also collect the sensor data from a LAN Network. - The temperature sensors transmit their temperature data to the receiver. - Several temperature sensors can be connected to the system at the same time. - Separate sensors for the Multilogger are available at your dealer. - We have connected 60 sensors to one single USB receiver without any problems. - The software graphically shows the temperature measurements of a longer period of time. - Extra: Attractive screensaver software showing all sensors. - The range of the sensors can vary as a result of environmental inuences. Depending on the material properties of the surrounding areas, sensors located inside refrigerator systems may not be able to communicate with the receiver.

H12 The Multilogger System consists of a logger loftware application, a USB-, LAN-,WIFI- or GPRS receiver module and one or more sensors TSN-XX, PRO-XX, IP-XX, each including a transmitter system. A USB- or LAN cable connects the receiver to the computersystem or to the LAN network. The Logger application can synchronize the sen- sor data from several receivers. For the multilogger system many different sensors are already availa- ble. The sensors can measure temperature -200 to +400°C (PT-100), humidity, Voltage and CO2 The multilogger application at the computer displays all sensor data, which have been transferred by temperature sensors to the receiver. Temperature sensors continuously registrate temperature and report new values to the USB-, LAN-, WIFI- or GPRS receiver at intervalls of ca. 45 seconds. Each sensor in the sensorlist reports the date and time stamp for the most recent measurement data set. The right side window displays a continuous curve for the registrated temperature for the selected sensor. Sensors and receiver use a wireless communication system, working at 433MHz. This frequency is freely available for communication at transmitting powers under 10 milliwatts. Depending on surrounding building constructions, the allowed 10mW power level allows a transmission range of 20-40 meters inside buildings,theopeneldrangeismuchhigher. Temperature sensors may be located inside or outside buildings, at any place where a registrated overview of temperature curves is desired. Unreliable signal levels may be improved substantially by slightly modifying the sensor’s position or the receiver’s location.

3. Transmission losses

Sometimes transmission losses may arise, indicated by missing temperature data in the sensor’s curve display. Data losses may be caused by:

1. Problems inside the USB, LAN, WIFI, GPRS-receiver

2. Problems in the temperature sensor module

3. Problems in the signal transfer between temperature sensor

module and USB, LAN, WIFI, GPRS-receiver 3.1. Problems inside the USB, LAN, WIFI, GPRS-receiver The receiver does not registrate a single data signal, even if the sensor is located at a minimum distance to the receiver. Potential problems: - USB-cable between receiver and computer is missing or defect. - Improper installation of the USB, LAN, WIFI, GPRS-module. - Unknown software problem in the computer system. Suggested solutions: - Check the display window in the temperature logger display foraeldinthelowerleftarea.Theeldistodisplaythevalue ‘ready’ continously. If the display intermittently displays ‘RF_USB-Communication failure’, the Windows operating system failedtondtheUSB-module. - Remove the USB-cable, wait about ten seconds and reconnect the cable. - Deinstall the temperature logger application software and reinstall it again.

Problems in the temperature sensor module The receiver receives signals from sensors, but fails to registrate signals from one sensor in particular. Potential problems: - Batteries are missing or are at a low charging level - Reversed polarity of the sensor’s batteries - The sensor’s location is outside of the receiver’s reception range - Damage to the sensor (by corroded battery contacts, moisture or battery leakage) - Problems in the radio signal communication Suggested solutions: - Insert fully charged batteries in the sensor and repeat the communication test (please check the polarisation of the batteries before inserting!!) - Check the battery contacts and remove all corrosion and moisture effects.

H17 3.3. Radio signal transfer problems The receiver system is missing signals from one or more sensors, or only receiving a limited number of signals. Potential problems: - Walls or ceilings between sensor and receiver may contain metallic constructions. - Sensors and/or receiver may be located on a metallic surface. - Sensor or receiver are situated in locations with high humidity. - Windows between sensor and receiver may contain several layers of glass or shielding materials or may be covered by humid moisture. - Other 433MHz systems may be working within the 20m operating range. - Interference or jamming signals from radio or TV transmitters. - Electronic or electrical equipment (eg. computer equipment or microwave ovens), operating within the 2-5m operating range. - Low power level of the sensor’s batteries (see 2) Suggested solutions: - Modify the locations of the sensor and/or the receiver. - Remove the interfering equipment.

4. Communication test

A simple test will check the communication channel between sensor and receiver:

1. Remove the batteries from the sensor.

2. If an entry already exists: remove the sensor from the

temperatur logger application (using the right mouse button).

3. Locate the sensor at ca. 1 m distance to the receiver.

4. Put the batteries back into the sensor.

5. A correctly working system will add the according sensor entry

to the sensor list within 5 seconds. Extra information and possible updates can be found on www.arexx.com (on the forum or through the Temp Logger menu). Further questions can also be put on our forum, see www.arexx.com
