System Migration: This file is a "Synergy" (syn) release package required for users who want to switch their DX80 from the newer Cisco Collaboration Endpoint (CE) interface back to the original Android interface.
Version Details: It is specifically version CE 8.2.0 with the Synergy build identifier 213B. How to Use the Firmware
To install or downgrade using this package, follow these general steps typically performed via the Cisco Unified Communications Manager (CUCM) or the device's web interface:
Preparation: Ensure your DX80 is currently running a version of CE 8.2.x. If it is on a much newer version (like CE 9.x), a step-by-step downgrade to 8.2.x is usually required first.
File Acquisition: Access the Cisco Software Download portal. Search for "DX80" and navigate to the SIP Software or Collaboration Endpoint sections.
Note: Cisco often "defers" older software, meaning it may no longer be publicly downloadable without a specific service contract or opening a case with the Cisco Technical Assistance Center (TAC). Installation: Log in to the Cisco Unified OS Administration page. Navigate to Software Upgrades > Install/Upgrade.
Upload the .pkg or .cop.sgn file from your local machine or a TFTP server.
Verification: After the device reboots, log in to the Cisco Unified CM Administration page and check Device Settings > Device Defaults to verify the "Inactive Load" or "Active Load" reflects the new version. Troubleshooting "Fixed" Issues
The "fixed" designation in your query likely refers to a version that addresses specific bugs found in earlier 8.2.x builds. Users often seek this specific build because it is known to be the stable "bridge" for the Android/Synergy transition. If you are having trouble viewing the download page, try switching browsers (e.g., from Chrome to Firefox), as some Cisco legacy pages have known compatibility issues with modern browser security settings.
The identifier DX80CE820SYN213BRELPKG refers to a specific firmware or software release package often associated with industrial automation components, specifically within the Banner Engineering DX80 Wireless Performance series.
When a package is marked as "fixed," it generally indicates a critical patch that addresses stability, synchronization, or logic errors found in previous iterations. Below is a detailed look at what this package entails and why the "fixed" status is significant for system integrators. Understanding DX80CE820SYN213BRELPKG
This alphanumeric string is more than just a serial code; it identifies the architecture and versioning of a wireless node or gateway's operating environment:
DX80: Refers to the Sure Cross® DX80 Wireless Series, a proprietary radio network used for industrial sensing.
CE820: Likely denotes the specific controller core or processor architecture (820-series) used in the hardware.
SYN213: Represents the synchronization logic version. In wireless industrial networks, "sync" is the most critical component, ensuring that nodes wake up and transmit data at precise millisecond intervals to avoid collisions.
BRELPKG: This identifies it as a "Bundle Release Package," a comprehensive file containing the firmware, bootloader, and configuration maps. Why the "Fixed" Designation Matters
In the world of Industrial Internet of Things (IIoT), a "fixed" release package usually targets three specific areas: 1. Resolution of Sync Loss
Earlier versions of the 213-series firmware occasionally suffered from "drift" in high-interference environments. If a node loses synchronization with its Gateway, the entire sensor network can go offline. The fixed package optimizes the radio’s frequency-hopping spread spectrum (FHSS) logic to maintain a tighter lock on the Gateway signal. 2. Enhanced Power Management dx80ce820syn213brelpkg fixed
For battery-powered nodes (FlexPower), software bugs can lead to "vampire drain," where the radio stays in a high-power state longer than necessary. The fixed BRELPKG ensures the microprocessor enters deep-sleep cycles immediately after the acknowledgement (ACK) packet is received. 3. Modbus/EtherNet/IP Mapping Accuracy
One common issue addressed in these packages is the "Register Offset" bug, where data from a sensor is written to the wrong Modbus register. The fixed version ensures that the internal I/O mapping aligns perfectly with the user’s configuration software (such as the DX80 Configuration Tool). How to Implement the Fix
If you are dealing with a system flagging this specific package requirement, follow these steps:
Backup Configuration: Before flashing the fixed package, use your configuration cable (typically the BWA-UCA-001) to export your current XML site file.
Verify Hardware Compatibility: Ensure your Gateway hardware supports the CE820 architecture. Attempting to flash this onto older 700-series hardware can "brick" the device.
Perform a Site Survey: After the update, run a new site survey. The "fixed" logic may change how the device interprets signal strength (RSSI), and you may find you can achieve better throughput with slight antenna adjustments. Conclusion
The DX80CE820SYN213BRELPKG Fixed update is a mandatory move for anyone experiencing intermittent data drops or high latency in their wireless mesh. By stabilizing the synchronization heartbeat of the DX80 system, this package ensures that your industrial telemetry remains as reliable as a wired connection.

The keyword dx80ce820syn213brelpkg fixed refers to a critical firmware package, dx80.ce8.2.0-syn213B.rel.pkg, used to resolve specific bugs during the software transition of the Cisco DX80 video collaboration system.
Specifically, this package was released to replace the older syn213 version to address a known issue (CSCve12723) that caused conversion failures or system instability. Below is a detailed look at why this specific "fixed" version is so vital for administrators and power users of the DX80. The Role of dx80ce820syn213brelpkg
The Cisco DX80 originally shipped with Android-based software but later transitioned to Collaboration Endpoint (CE) software, the same operating system used by Cisco's dedicated room systems like the SX and MX series. The dx80ce820syn213brelpkg (version CE8.2.0 Synergy 213B) is the specific file used for: Summary
Android-to-CE Conversion: It acts as the "bridge" firmware required to move the device from the old Android OS to the more responsive CE environment.
CE-to-Android Downgrade: Paradoxically, it is also the essential first step for users wanting to revert their DX80 back to Android to use it as a generic tablet or for legacy phone features. What Was "Fixed" in the 213B Version?
The original syn213 package (without the "B") had a flaw that prevented many units from completing the software swap correctly. The fixed syn213B version was released by Cisco to resolve:
Bug CSCve12723: A critical bug fix for conversion software that could cause the process to hang or fail.
Audio Stability: Addressing issues (like CSCvb27626) where audio might be lost on HDMI inputs or outputs after a software change.
Responsiveness: The CE 8.2.0 software lineage was noted for being significantly more "snappy" than the Android builds, reducing UI lag during video calls. Why This File is Hard to Find
As of May 2026, Cisco has deferred many CE8.x software releases. This means they are no longer officially available for download on the Cisco Software Central site due to their age or security vulnerabilities in older versions.
Because the "fixed" syn213B package is the only reliable way to move between operating systems, it has become a "holy grail" for IT professionals managing legacy hardware. Many users on Reddit's CiscoUC community and the Cisco Community Forums frequently seek this specific package to rescue "bricked" units or to repurpose the DX80 as a high-quality 23-inch touchscreen monitor.

If you’ve landed here, you’ve likely been staring at a BOM (Bill of Materials), a repair sheet, or a legacy engineering drawing that includes the string: DX80CE820SYN213BRELPKG.
The first thing you need to know is reassuring: You are not missing a standard datasheet. This code does not appear as a standard commercial part number from major distributors (DigiKey, Mouser, Arrow) or silicon vendors like Texas Instruments, Analog Devices, or Microchip.
So, what is it? And more importantly, how do you fix it or replace it?
Let’s break it down.
The most common issue engineers face is that custom codes are not cross-referenced in public databases. You cannot simply type DX80CE820SYN213BRELPKG into Mouser and get a hit.
The “fix” requires reverse-engineering the intent of the part.
