Product description General product description In connection with a base module alpha WSN BM 1x0, the sensor module alpha WSN SM 230 forms a universal wireless network for the sensor data acquisition. If required, repeaters (alpha WSN RM 300 or alpha WSN RM 300-G) can be used for the extension of the range.
Product description The sensor data acquisition is often connected with much installation work (laying of a multitude of cables in areas that are often impracticable and separated) and / or high personnel expenditure (manual reading of single sensors, interpretation of the measur- ing results regarding exceeding of the limit etc.).
Description of device-specific features Repeater module The repeater module is for the transmission of the sensor data to the base module. It is used in case of difficult radio propagation conditions or in case the distances between sensor and base module are too great. The voltage supply is realized via an external power supply unit.

Putting into operation Putting the units into operation Delivery status The RS232 interface of the base modules and the virtual COM-Port of the base module alpha BM 120 (USB-Port) are set to the parameters 115,200 baud, 8 data bits, no parity bit, 1 stop bit. The setting of the virtual COM-Ports at the base module alpha BM 110 and alpha BM 130 is carried out similar to this.
Putting into operation Initial state of the sensor module after starting When putting the sensor module into operation in battery mode, the analogue out- puts as well as the UART interface are deactivated. Insert the battery according to the polarity at the sensor module. If the sensor module is supplied with voltage by means of a power supply unit when putting it into operation, the analogue outputs (channel 1 and 2) as well as the UART interface will be deactivated.
Putting into operation Mounting General instructions Please read the chapter "Antennas" before mounting the units to walls, ceilings or into housings! Mounting instructions for the base module alpha WSN BM 1x0 The base module has to be operated in the indoor area. You just have to mind that there are good propagation conditions.
Putting into operation Configuration of the interfaces Setting the RS232 interface or settings at the terminal programme In case your computer has a free COM-Port (9-pole), you can use this connection for the connection with the base module. Then it will not be necessary to install additional drivers.

Putting into operation 3. Twice click on the entry "Digi Connect ME Port y (COMx)". A new COM-Port (COMx) should be entered here now. The "x" stands for the respective COM-Port that has to be set, e. g. COM4. The "y" stands for the appropriate LAN-Port, since several base modules in the LAN can also be administrated from one PC.
Putting into operation Automatic setting of the IP address The LAN module of the base module alpha WSN BM 110 is set to DHCP by default. So the IP address will automatically be assigned in case a DHCP server exists. Manual setting of the IP address In case no DHCP server is available, the IP address can also be configured manually.
Putting into operation Setting Serial-Port-Profile So that the base module of the wireless measurement system works best possible, it is necessary to configurate the Serial-Port-Profile of the WLAN module correctly. For this purpose, select the point "Serial Port" on the configuration page under "Configuration" and set the Radio Button to "RealPort".
Putting into operation Setting the WLAN interface The base module alpha WSN BM 130 provides the opportunity to make the received data available over a WLAN. The PC, on which the data shall be displayed, has to be equipped with WLAN or with a LAN port for the connection of a WLAN access point as well as with an Internet browser.
Putting into operation Manual setting of the IP address In case no DHCP server is available, the IP address can also be configured manually. Proceed as follows: Open a browser (e. g. Internet Explorer) and enter the current IP address of the WLAN module into the address line.
Putting into operation Setting the encoding If you want to use an encoded radio transmission, the encoding will have to be acti- vated. Proceed like at the manual setting of the IP address. But then select "Wireless Security Settings" on the page "Network Configuration". Now you can carry out the desired security settings.

Operation Login procedure PC at the base module The base module has the possibility to buffer received data sets in case of temporary switching off of the PC. A registration of the PC at the base module is necessary to control this mechanism.
Operation CRC calculation A check sum is added to every packet of data. This is a check value with which errors in the packet of data can be found out. The basis of the CRC calculation is a table with 256 elements. By means of this table, the correct check sum is determined for every packet.
