Load Simplify File via Secure File Transfer Message (Tran Type 36-07)

Simplify supports a Load Simplify File via Secure File Transfer message from the POS process.

The POS system can send Simplify a Load Simplify File via Secure File Transfer when the POS system wants Simplify to request a file download from a secure file transfer server. The file to be downloaded must be specified in the message from the POS. The location of the secure file transfer server is specified in the Simplify parameter files (by either IP address or host name). This message can be used to initiate a download of a new version of Simplify, new parameters, new form files, etc. After a successful download, Simplify will reboot the PIN pad, without sending a response message to the POS. If Simplify cannot complete the download, Simplify will send a Load Simplify File via Secure File Transfer Response message to the POS system, containing a Status Flag indicating why the download could not be completed.
