AA Daytona Sensors LLC Engine Controls and Instrumentation Systems User Instructions for WEGO Log Software CAUTION CAREFULLY READ INSTRUCTIONS BEFORE PROCEEDING THE USER IS ASSUMED TO BE FAMILIAR WITH MICROSOFT WINDOWS AND PC OPERATION OVERVIEW WEGO Log software runs under Microsoft Windows 98 ME XP This software allows WEGO II users to download and display data logged by the unit and to setup certain data logging functions After WEGO Log is launched the main screen appears blank Data logged by the WEGO II unit must be downloaded before it can be displayed by using the Download Data From WEGO command on the Communications menu Once data has been downloaded it is automatically displayed on a chart recorder type screen You can save this data by using the Save File command from the File menu You can also display a previously saved data file by first using the Open File command on the File menu A sample data file Sample log for an actual road test is included in the program folder PC REQUIREMENTS The WEGO II has a female 9 pin D sub connector that interfaces to an RS 232 serial port on the laptop PC In most cases you will need to use a 9 pin male to female extension cable such as our P N RS232 CBL 10 to reach the PC Similar cables are available from Belkin www belkin com as P N F2N209 06 T or Office Depot as P N 825851 You can also find the same type of cable at most office and computer supply stores
3. Data transfer occurs at 56 kBaud The high baud rate limits the maximum cable length and the use of an extension cable over 12 feet in length is not recommended Due to the cable length limitation and the need for portable access a laptop PC is recommended The PC must have a free serial port COM1 255 with a standard 9 pin male D sub connector If your laptop does not include a serial port you can use a USB adapter However not all USB adapters will work correctly with the WEGO II Most of the inexpensive USB adapters are intended for interfacing Palm Pilot type devices and do not support the high baud rate required by our unit We sell and recommend a low cost USB adapter P N USBG 232 that has been tested with a wide Daytona Sensors LLC 933 Beville Road Suite 101 1 S Daytona FL 32119 386 322 7390 www daytona sensors com range of system configurations The USBG 232 adapter comes with correct and updated driver files on CDROM After installation the USBG 232 adapter will usually appear as COM5 We recommend a laptop with Pentium processor and super VGA display SVGA with 1024 x 768 pixel resolution running Windows 98 ME XP Data chart display is graphics intensive and a high speed Pentium processor is recommended Processors slower than 300 MHz will exhibit sluggish program loading and response The PC must have a CDROM drive for program loading WEGO Log includes print commands to print downloaded data The program has
