Loss OF DOWNGRADE CAPABILITY

Do not upgrade to firmware version 4.0.0 or later if you need to downgrade the meter in the future.

Failure to follow these instructions can result in loss of firmware downgrade functionality.

Prerequisites

  • Back up all your meter data.

New features

This section lists the new features that are added to your meter after you upgrade to firmware version (set in target).

Secure ION

Secure ION enhances the security of the ION protocol by using a Transport Layer Security (TLS) encrypted tunnel between the device and the controller.

The additional TLS layer applies to TCP/IP based connections (Ethernet) only. It does not apply to serial communications.

NOTE: ION protocol without Secure ION is still supported and enabled by default upon upgrade to 4.0.0.

For more information, see Secure ION.

ION sessions

An ION session uses a session token ID to authenticate ION requests to a device.

For more information, see ION sessions.

Longer passwords

In keeping with our ongoing efforts to provide enhanced cybersecurity, the maximum password length has been increased from 6 to 16 characters.

Longer passwords cannot be used over non-ION session connections.

File system improvements

Firmware version (set in target) includes additional file system and related changes from the vendor.
