How to interpret revision numbers
Step1 : LoginàAboutàFirmwareàDone!
1. Open the Browser.
2. Type in IP address of Gateway. By default: 192.168.2.101
Continue with HTTP. Note that this can be changed later.
3. Enter the Username, by default, "admin". All in lower case and with no quotes.
4. Enter the password. Can be found on the back of the gateway.

Understanding Firmware Revision Numbers
Firmware revision numbers are used to identify the exact software build running on a FieldServer or CAS Gateway. These revision identifiers are critical when troubleshooting issues, validating compatibility, or confirming whether a device is running a required feature or bug fix.
A revision number typically represents a structured versioning scheme defined by the manufacturer. While the exact format may vary slightly between product families, the revision generally conveys information about the major release, minor updates, maintenance patches, and internal build iterations.
For example, a firmware revision such as 5.2.1.34 can be interpreted as:
- 5 – Major release (significant functionality or architectural changes)
- 2 – Minor release (feature enhancements or protocol updates)
- 1 – Maintenance or patch release (bug fixes, stability improvements)
- 34 – Internal build or compilation number
The most important portion for most users is usually the major and minor version. These indicate whether the firmware supports specific drivers, protocols, or features required by your application. Maintenance and build numbers are primarily useful when working with technical support or engineering teams.
Why Revision Numbers Matter
Knowing how to interpret revision numbers allows you to quickly determine whether your device is up to date, running a supported version, or potentially affected by a known issue. Many support cases begin with identifying the firmware revision so that known fixes, limitations, or configuration requirements can be confirmed.
When reporting an issue to support, always include the full firmware revision exactly as displayed in the web interface. Omitting the build or patch number can lead to confusion, especially when multiple releases exist within the same major version.
Revision numbers are also important when following documentation or application notes. Instructions may apply only to certain firmware versions, and behavior can change between releases as protocols evolve or new features are introduced.
Best Practices
- Record the firmware revision before making configuration changes or upgrades
- Verify compatibility with your protocol drivers and third-party systems
- Confirm revision requirements when applying configuration files or templates
- Provide the full revision number when contacting technical support
If you are unsure whether your current firmware revision is appropriate for your application, or if you are planning an upgrade, we recommend consulting Chipkin support before proceeding. This helps avoid unnecessary downtime and ensures a smooth commissioning or maintenance process.
