Firmware Upgrade

If the firmware needs to be updated, NovAtel provides two methods of updating the firmware image:

Using Softload commands. While the receiver is running, Softload commands can be used to download a firmware image to the receiver. This download can be done over any communication port: COM1, COM2, COM3 and USB. Alternatively, a host controller can issue the Softload commands over COM1, COM2 or COM3 to download new firmware to the receiver module. See Updating Using SoftLoad Commands for information.
Using NovAtel Application Suite (NAS). NAS is a software program that can be used to upgrade the firmware on the OEM7500. NAS can be downloaded from novatel.com/products/firmware-options-pc-software/novatel-application-suite. For information about using NAS, see docs.novatel.com/Tools.

Ensure that proper voltage levels are used when communicating between the OEM7500 and the computer. Applying high voltages to COM1, COM2 and COM3 pins can damage the OEM7500.
