different ways: remotely, using SFTP; locally, using a USB flash drive, or by removing the microSD
card and copying data off of it directly.

5.1 Remote download

Remote access to the AL205R/AL205B is disabled by default. To enable it, launch A2Control
software, click the gear icon, click the IP Settings tab, and set the Network Password.

Connect to the AL205R/AL205B with the following parameters:

TCP/IP Address: [as configured or setup using DHCP]
Port: 4422
Username: alert2 [all lower case]
Password: [as configured in the AL205R/AL205B]

Received ALERT2 data is stored in the decoder_output folder. Files are named [AGENCY_ID]_
[DATE].gz and are compressed with gzip.

System logs are stored in the logs folder. Each subsystem has its own folder with the most recent
logs stored in it. These logs are not intended to contain useful information for day-to-day use of
the system, but may be helpful for troubleshooting.

5.2 Local download—USB flash drive or
microSD card

When a USB flash drive is inserted in the USB port, the AL205R/AL205B automatically copies
system logs onto the USB flash drive in a folder named [AGENCY_ID]-[SOURCE_ADDRESS]-
[DATE]. To copy the received ALERT2 data from the device, create a folder called decoder_output
in the root folder of the USB flash drive. The AL205R/AL205B copies ALERT2 output files to that
folder if it fined it. The AL205R/AL205B must be powered for at least two minutes for it to register
the USB flash drive.

CAUTION:
The AL205R/AL205B is not compatible with the exFAT file system. Therefore, USB flash drives
using the exFAT file system must be reformatted to the FAT file system.

To copy data directly from the microSD card, remove power from the AL205R/AL205B then
remove the card from the device. Reinsert the card after copying the data before connecting to
power.

CAUTION:
The AL205R/AL205B automatically reformats the microSD card if it is using the exFAT file
