Note:
When transferring files via TFTP, do not create a file on the server called "testfile".
Communications between the D4T and the TFTP server is tested prior to starting a
transfer using this filename while then verifying the response from the server.
- Log To: USB or Internal Memory.
Note:
When transferring files via TFTP or Samba, internal memory must be selected here.
Note:
There are many USB memory devices available. Watlow does not recommend using
micro SD or SD card to USB adapters in the USB slots. Be aware that we have not
tested all of the variations of USB memory devices but we have tested and validat-
ed those that are listed below:
• Lexar, Kingston, Toshiba and Verbatim
