are present.
• Ensure that the download is exactly what you want your receiving device
to receive.
2 Configure the sending device to receive an application download from a PC:
• From SYS MODE MENU 1, set Group 1 and COM2 as the port to receive the
download.
3 Connect a cable between the RS-232 serial ports of the PC and the sending
device.
4 Initiate the file transfer on the PC.
5 From SYS MODE MENU 1 on the sending device, select either a full or a partial
download using a UART Dongle connected to each device.
The PC transfers files to the sending device.

The OS software on the receiving device is not affected by a back-to-back
application download.
Note: OS files cannot be downloaded on a back-to-back operation.

An application upload does not overwrite the existing certificate tree on the
receiving device. Any downloaded certificate files are authenticated and added to
the tree.
