| Why do I need to download firmware 
              to my controller?Only the machine developer knows what firmware 
              version and configuration works with their application. By downloading 
              firmware directly, you have complete control over your development 
              and release versions. Why do I need to download runtime 
              FPGA images to my SynqNet nodes?The node FPGA runtime images are tested and distributed 
              with the software package. Using node FPGA runtime images from other 
              software releases might work properly, but may not contain all the 
              features needed for a particular software release. To guarantee 
              compatibility, you should always use the node FPGA runtime images 
              included with the software package.  Why can't MEI download firmware to 
              my controller at the factory?MEI can download your firmware, but it is expensive 
              and causes several problems:

                    You would need a custom part number for each controller 
                      with a different firmware image. Even if you use the same 
                      controller hardware in several machines, each version would 
                      need to be ordered, purchased, tracked, and stocked separately. 
                      
 
Changing a firmware image (version or configuration) would 
                      require a new part number. This causes transition problems 
                      between "old" parts and "new" parts.
 
Repairs and replacements are much more complicated. 
 
Field upgrades are not possible. Controllers must be returned 
                      to the factory to receive new firmware and a new part number. 
                     |    What if I need to upgrade software 
              in the field?If you configure the flash memory as part of your 
              application or installation, then it is very easy to upgrade software 
              and/or firmware in the field. If you do not, you will need to manually 
              update the flash memory. Can I modify the FPGA (.fpg and 
              .sff) files?No. These files are binary and do not contain 
              any configuration data.    |
