This command sends the file data to the unit. The file being transferred is divided into multiple data commands. There can be as many data commands as needed to send the whole file. The maximum data in one command is 4000 bytes. At the start of each data block there is a header #800001234 which tells that 8 following digits gives the length of block.
The example below depicts the transfer of a file. The first DATA command depicts the transfer. The checksum shown cannot be recreated from the file data because the end of line characters cannot be identified from the text below.A space must separate the DATA command from the “#” character.
This command not allowed during scenario execution, and will result in the error code “-190,"Execution in progress"”.
