SVSi N3000 Series: Decoders Dropping Offline During RS-232 Serial Data Transmission

Brand:

AMX

Affected Products:

AMX SVSi N3000 Series Encoders and Decoders

Summary:

On AMX SVSi N3000 Series encoders and decoders connected to NetLinx controllers, receiving RS-232 serial data can cause the units to go offline or drop off the online device tree. Applying the updated NetLinx Native Hotfix package (version v2.12.132 or higher) resolves the serial communication handling and maintains stable network connectivity.

Troubleshooting:

End-User Action:

Download the updated NetLinx Native Hotfix firmware package (version v2.12.132 or higher) from the internal SharePoint or technical resource portal.
Load the firmware update onto the affected N3000 Series encoders/decoders.

Resolution: Update N3000 Series endpoint firmware to version v2.12.132 (or higher) with the NetLinx Update Addon included.
Verification: Transmit RS-232 serial control strings through the decoder's serial port while monitored by the NetLinx Master controller. Confirm that the device remains fully online in the NetLinx active device tree without dropping communication.
