The 5400 Arroyo Update program is used to upgrade your 5400 TECSource temperature controller to the latest version of firmware. Updates are released to add features, fix bugs, and otherwise improve the operation of the instrument.

The current firmware version is 3.13.6

This firmware update can only be used on firmware versions 3.07 or later. If you are running firmware version 3.06 or earlier, you will need to contact the factory to upgrade your instrument.

If you are already running the current version of firmware, there is no need to run the update program. The firmware version can easily be found as it is displayed on power-up.

To upgrade your instrument, you will need to have the instrument connected via USB and the USB drivers loaded.
