1. Use Checksum on packets Get packet validation Display help VMNK KS SDNYRO SOk PARBLDR gt Firmware upgrades are performed using the XMODEM protocol The PAR bootloader uses 128 byte packets and supports both CRC and checksum error checking A typical upgrade procedure is as follows 1 Press X to instruct the bootloader to use CRC validation on packets 2 Press W to initiate the transfer 3 Immediately browse to the folder containing the sfw file and transfer the file using XMODEM Ensure the option to use CRC checking if present is enabled some emulators autodetect the validation type Note the bootloader will time out after about 10 seconds if the transfer doesn t begin after a few seconds cancel it and repeat step 2 4 When the transfer completes validate the upload by pressing V 5 If the program validates press A to instruct the PAR sensor to execute the application by default otherwise it will return to the bootloader on the next power cycle 6 Press S to start the program immediately or power cycle the PAR sensor 7 When the new firmware starts enter the command console by pressing the key Check the banner to ensure that the new firmware version the X Y Z portion of the sfw file name is reported Copyright 2015 Satlantic LP All rights reserved User Manual SATLANTIC SAT DN 00633 Rev E PAR Sensor Serial M S 2015 02 10 Page 31 of 40 4 2 Analog Int
