5 2. Description of the CME8i 2.1. Introduction CME8i DESCRIPTION M-BUS Easy CME8i is device for wireless data transfer from meters with communication bus M-BUS (heat meters, water meters, electro meters, etc.) CME8i enables remote data gathering from these meters, from any dispatching, PC, Internet etc. via GSM- GPRS network. CME8i is basic communication unit in data collection system, built on MEGABUS-MASTER protocol (see: [1]). For easy use, the CME8i is in compact housing with integrated accumulator and GSM antenna. M/BUS interface is short-current proof, with function indication. As transmission protocol is used TCP in transparent mode Examples of possible applications Measuring in thermo industry. Measuring in water industry. Measuring in energy industry M-BUS port On port is standard M-BUS interface. More see the chapter Sleep mode It is possible to use power management in CME8i. Modem always switches into low power consumption after user defined time, because of possible discharge of accumulator or battery. And finally in case waking up on scheduled time after connection termination from remote side, e.g. from dispatching. Power consumption is very low in sleep mode (max. 100 µa). Modem can be wake up to online mode only by pressing button TL1 (see the picture) or by set up time to wake up modem.

It can be accessed by entering IP address of router to web browser. Default IP address is Configuration can be done only by user named root with default password root. This password must be changed in web configuration (see chapter ). The left part of the web interface contains the menu with pages for monitoring of the Status, configuration and Administration of the modem. After PWR LED starts to blink it is possible to restore default settings by pressing button TL1 for at least 5 seconds Network status Information about network status is possible to find in menu in sum Network. In window is displayed information about network interfaces. For every interface can be seen this information: MAC Address hardware(unique) address of networks interface (only for LAN) IP Address own IP address Rx Bytes count of received Bytes Rx Packets count of received packets Rx Errors count of received errors Rx Dropped count of dropped packets Tx Bytes counts of transmitted Bytes Tx Packets count of transmitted packets Tx Errors count of transmitted errors Tx Dropped count of dropped packets 18

19 WEB CONFIGURATION If the GPRS connection is active, in Network is displayed his network information GPRS status GPRS item consist of actual information about SIM card and about settings PIN code on SIM card. If the SIM card is not properly inserted or is it locked by PIN code, user is informed about it. Also is possible to find here information about connection to mobile network. They are: code of operator (PLMN), cell, channel, signal quality of chosen cell, as well as about neighbouring hearing cells. If the signal strength is in red, this means that signal is insufficient and connection could be inaccessible. If is in red the signal strength of some neighbor cell, it means that could interfered with selected cell. In this case, solution could be to adjust GPRS antenna. (See chapter 4. ) 19

20 WEB CONFIGURATION In this given example can be seen that there is thread of reselection between chosen cell on channel 30 and neighbor cell on channel 80, because their signal strength is very close Power status Information on power supply can be called up in option Power status in the main menu. Window is separated into 3 sections. Each section represents one available battery. If battery is inserted, type of installed battery, voltage and estimated capacity is displayed. In case of fixed power source, only status of supply voltage is displayed. Sections VBAT1 and VBAT2 displays operational parameters of external batteries. For example accumulator that can be connected to battery connector BAT1 and BAT2. VBAT providing voltage and capacity of internal battery for run in sleep mode. Type of external battery can be chosen in Power management in main menu (see chapter ). Choice of the battery type has influence to estimated capacity of the battery Wake up status Information about power supply can be called up in option Wake Up Status in the main menu. It is possible to find here these information: Reset time time, when modem have woke up from sleep Current time actual time in the moment of the page upload Next activity time time of next activity Next wake up time time of the next wake up from sleep mode Time to sleep time remaining to switch to sleep mode 20

21 WEB CONFIGURATION 3.5. Run log Run log can be called up in option Run log. Information like wake up time and sleep time are stored here System log In case of any problems with modem, system log can be called up in option System Log.

22 WEB CONFIGURATION 3.7. LAN configuration To enter the network configuration, select the LAN menu item. In the first part of the window is possible to define the network interface IP address and the network mask (Subnet Mask). In second part of the window is possible to define the DHCP server by checking the Enable DHCP server. In window it is possible to define the beginning (IP pool start) and end (IP Pool End) of the pool of IP addresses which will lease to DHCP clients. If enable DHCP server is left unchecked the DHCP server will not lease IP addresses. The changes in settings will apply after pressing the Apply button. The DHCP server assigns IP addresses to the connected clients from defined address pool, IP address of gate and IP address of the primary DNS server. It is important not to overlap ranges of static engaged IP address with address allotted by DHCP, or collision of addresses may occur, thereby malfunction the network GPRS configuration To enter GPRS configuration select the GPRS menu item. Here can be entered access point name (APN), username and password. If the Check PPP connection option is selected, it has active control of connection over PPP. The CME8i will automatically send the ping question to the selected domain name or IP address (Ping IP Address) in periodic time intervals (Ping Interval). After three unsuccessfully pings on appropriate IP address the router terminates connection and tries to establish a new connection. It is possible to use, for example, the DNS server of a mobile operator as the ping IP address. If the Enable Traffic Monitoring option is selected, then the CME8i stops sending ping questions to the Ping IP Address and it will watch traffic in PPP connection. If PPP connection is without traffic longer than the Ping Interval, then the router sends ping questions to the Ping IP Address. The changes in settings will apply after pressing the Apply button. 22

36 LINKS AND INFORMATIONS 4. Quality of the GPRS signal CME8i Modems works with the aid of the GSM network. Modems contain GSM-GPRS modules, which are on the radio channel connected to a certain GSM cell. Its signal can be evaluated and displayed in web configuration of CME8i modem. The function is used first of all when installing the station and checking its function. From the obtained information, the following can be read: On which channel the station operates what is its signal strength, what neighbor channels are available and what their signal is strength. These data are often indispensable for the correct installation of the antenna Antenna installation for modems Good placement of antenna is required for good function. Important factors are GSM cell signal strength and signal quality. Signal strength could be obtained in web configuration in GPRS menu item. Second part is quality of signal. There is no exact measurement. Good point of view is from data transfer statistic. If number of lost packet is low, signal quality is good Good quality GPRS requirements: Serving cell signal better than 90 dbm, Adjacent cell signal below 12dB to serving cell, otherwise risk of interference If many cells with close levels (<3 db), be in danger of reselection (switch between cells, that caused bad time response or communication interruption). In this case is needed to extend difference between signals Example, station received these signals: PLMN : Cell : 69A6 Channel : 30 Level : -71 dbm (Ok) Neighbours : -76 dbm (80), -77 dbm (106), -82 dbm (57) 36

37 LINKS AND INFORMATIONS What does it means: module received cell 69A6 on channel 30 with level 71dBm, operator is 23001, there is possible to interference from channel 80, with level -79dBm, there is possible to reselection between channels 80 and 106, its level is so close. Way to fix Change type (from unidirectional to directional e.g. yagi), direction or place of antenna. After changing you must do measurements again. 5.

The customer shall present duly filled warranty and the complete subject of the complaint. Subject of the complaint shall be presented in a condition adequate to that at the moment of purchase. Caution! The vendor is not responsible for keeping individual settings or data saved in the subject of the complaint.

Processing the complaint The vendor shall provide a free remedy depending on particular conditions, or replace the subject of the complaint for a new product, or settle the matter in another manner in compliance with the Civil Code and the Act on consumer s protection. As of the moment the claim is registered by the customer and the subject of the complaint is taken over by the vendor the vendor the guarantee period stops running. The guarantee period continues on the date of takeover of the repaired subject of the complaint or replaced faultless product by the customer, or should it not be taken over on the date the customer is obliged to take over the repaired or replaced product. In case the vendor replaces the subject of the complaint for a new product (including IMEI replacement) the original subject of the complaint becomes property of the purchaser. Since takeover of the new product a new guarantee period starts. In the cases when the vendor settles the matter after agreement with the customer by replacement of the subject of the complaint for a faultless product the new guarantee expires. 38
