Collector Connector (CC27)
SDR CheckSum Error
A numeric value called a checksum is used on the Lietz and Sokkia data collectors to verify the integrity of the data file once it has been transferred.
If you are sending a file to a Lietz or Sokkia data collector and the data collector displays the message it means that the file received by the data collector does not exactly match the file that was sent.
If you are receiving a file from a Lietz or Sokkia data collector and the file received on the PC does not exactly match the file that was sent, Collector Connector will display the following message:
Possible bad transfer on sdr checksum verification! It is recommended that you re-transfer the file from the data collector.
It is always best to retransfer the data file after any checksum error occurs. If the message occurs for every transfer, and you have determined that several files are indeed correct, you may wish to disable the error checking by enabling the Disable SDR CheckSum Verification option on the Advanced Configuration Screen.
