Sentry SR25 - How to obtain a log file from the SR25 device.

Use this procedure to collect log files from a Pharos Sentry SR25 device for troubleshooting.

The SR25 requires a valid SR25.zip file on the USB drive to write logs.

If you only need logs and do not want the device to reconfigure itself, add an empty file named noconfig.txt to the root of the USB drive.

Use a USB flash drive formatted as FAT32.
Make sure the USB drive has the correct SR25.zip file for the target environment.
Do not modify the contents of SR25.zip.
Optional: create an empty file named noconfig.txt in the USB root if you want to collect logs without reconfiguring the SR25.

1. Prepare the USB flash drive.

For Blueprint or Uniprint, download the SR25.zip file from Sentry Base.
For Pharos Cloud, sign in to the Pharos Cloud web console, go to Secure Printers, choose Deploy SR25 Hardware Guide under External Card Reader, and download the SR25 hardware configuration package.

2. If the USB drive already contains old SR25 log files, remove them so the new files are easier to identify.

3. Power on the SR25.

4. Insert the USB flash drive into the SR25 and wait for USB activity.

In current cloud guidance, the device may begin cycling its lights after several seconds while it processes the package.

5. Remove the USB flash drive and connect it to a laptop.

6. Check the root of the USB drive for the log files.

Log files are present on the USB flash drive after the SR25 processes the package.
If noconfig.txt was used, the SR25 writes logs without reconfiguring itself.

Important: The SR25 writes logs only if it sees a valid SR25.zip file and validates its signature.
Important: If SR25.zip is modified manually, the file becomes invalid.
Very early SR25 firmware did not write a log file at all. Later versions did, and the most recent versions write logs to USB every few seconds.
Use the SR25.zip package generated for the correct environment. Sentry Base and Pharos Cloud do not use the same retrieval path.
