1. The VCP Driver and the D2XX Driver cannot be installed simultaneously The creator of both of these USB drivers is FTDI Ltd More information can be found on their web site at www ftdichip corm Please see other important information concerning usage of the USB port under the additional comments section of this manual GPS Analyzer Included on the installation CD is a GPS analyzer This program is beneficial for the NMEA Datastream of the GPS Module and can be used to evaluate any recorded position data VDL 1000 Configuration data and CompactFlash Card The CompactFlash must be formatted in a FAT32 data format A default configura tion file is loaded onto the CompactFlash when it leaves the factory A back up of this file can also be found on the installation CD which if necessary can be re written onto the CompactFlash Upon starting the VDL 1000 it will read the configuration data from the Compact Flash and configure itself accordingly If a CompactFlash configuration file is not present it will revert to the default configuration file which is also stored internally It is possible with simple commands to arrange a specific configuration file to fit different needs This includes definition of wake up signal sleep time CAN filters active ports etc The custom configuration file can then be used by simply writing it onto the CompactFlash More is explained about this in the next chapter of this manual Introduction Short Overv2. ing the CF card the sample rates of the analog channels the CAN bus load and the USB Interface CompactFlash card The CompactFlash interface of the VDL 1000 only supports Type1 cards with a 5V tolerant power supply and a sector size of 512 byte The only supported file system on the card is FAT32 The partition size of the card should not exceed more than 2GByte since bigger parti tions are not supported on CF cards by FAT32 The partitions on the card must be formatted in FAT32 Every other system will lead to an error message and the card will not be accepted Attention The VDL 1000 must not be turned off or removed from power when logging to the CompactFlash card This will destroy the file system and all information on the card will be lost The card must then be reformatted with FAT32 Removing the card during logging will also cause these problems and data loss The card should only be removed in configuration mode Analog Channels The highest allowed sample rate for the analog inputs is 20 sps sample time 50 millisec onds in binary mode and 40 sps sample time 25 milliseconds in ASCII mode Higher sample rates are possible but might cause data loss on either the analog channels or the CAN nodes CAN nodes The CAN nodes one and two support high speed CAN C with up to 1Mbps CAN node three supports CAN B with up to data rates of 500kbps All CAN nodes need a two wire differential CAN line as inputs The VDL 1000 needs 10
