Known issues and advisories
December 2019 Version 2.12
END OF SUPPORT ANNOUNCEMENT
The CX23-R has been discontinued and development support for this module will officially end with a CX23-R firmware version tentatively set for Q1 2020. Maintenance support (i.e., bug fixes only) will continue for some period of time. Please contact HBM support at support@usa.hbm.com to discuss upgrade options.
New or revised issues and advisories:
- Advisory on SIE data file names. Google Chrome and Mozilla Firefox are currently the recommended browsers for accessing the web interface of the XR system. However, Chrome and Firefox browser updates have removed recognition / support of some special characters in file names, in some cases resulting in faulty SIE downloads or unrecognizable SIE file names. To completely preclude potential problems, it is recommended that both SXR setup names and SIE file names consist of only numbers, letters (upper and lower case), and the ‘_’ character. Of course, users can use special characters if they desire and do not encounter problems. If problems are encountered, the user can rename the SIE files via the user interface and run the download again. Following are some known problems. Using the ‘#’ character will result in problems when using the Download Manager application. Using the ‘(‘ or the ‘)’ character will result in problems using the current version of Firefox. Using the ‘%’ character will result in problems using the current version of Chrome.
- Issue with Garmin GPS modules not proving correct Day, Month, and Year data. Some of the Garmin modules delivered to customers in the past have a firmware version that does not provide the correct date parameters noted above. All other Garmin parameters are provided correctly. The only way to fix this is to update the Garmin firmware. This is a somewhat complicated procedure requiring special Garmin software and cabling. Customers who want their Garmin module(s) updated can contact Somat customer (support@usa.hbm.com) to make the arrangements.
Errata (advisories)
- Recommended browsers. The recommended browsers when using the CX23-R web interface are up to date versions of Chrome and Firefox. The web interface may work on other browsers but may result in degraded or undesirable operation.
- SIE file naming conventions when using FTP upload. Please note that file naming conventions and special character usage can affect whether the FTP server you are uploading to, will accept the file. There are characters that are illegal file name characters in Windows systems, and likewise for Linux systems. Please avoid these illegal characters when considering what operating system your FTP server is running on.
- Limitations on CAN database Vector DBC file export.
- CAN database Mode dependent channels are currently excluded.
- CAN database CCP channels are currently excluded.
Errata (known issues)
- Single channel editor locks up very rarely. The single channel editor (SCE) can get into a state where it cannot be closed. This can happen when the SCE automatically starts a Strip chart or other data display when opening the SCE dialog window, and the system cannot provide data for the display for some reason. The user can refresh the browser to close the SCE dialog window. There is also a User preference to not automatically start any display in the SCE dialog window.
- Sporadic MX module HANDLE SUBSCRIBE error. This error is seen rarely after a system boot from a power cycle or software initiated reset. The system reboots on this error and will automatically restart an SIE test that was running when the initial power cycle or software initiated reset occurred.
- Limitations on using MX471 modules. The MX471 can be overloaded and not able to keep up with the processing required if there are too many CAN channels assigned. This is significantly affected by the CAN bus load – specifically the broadcast rate of the CAN messages. For example, the following test scenario will result in an overload. Test using all 4 ports with 128 channels assigned to each port (using 32 CAN messages per port) broadcast at 100 messages per second. In most cases, the XR system will reset on an overload situation, but not always. As such, users are strongly advised to avoid MX471 overload situations – particularly for unattended testing.
- Web browser exceptions. The web browser interface will sometimes lock up or not properly reflect the actual states of the hardware or test. Refreshing the browser will usually correct this.
- Potential loss of data sync issue when using Firewire with MX modules. In certain usage scenarios, MX modules can lose PTP sync when a test run is restarted after a reboot. Connecting an MXB module to any other MXB module using FireWire without both having an Ethernet connection to the data processor can result in acquired data not being synchronized to the data processor on one or more MXB modules.
- EX23-R PTP Synchronization with MX modules using ports 5 and 6. Using a system connected with MX modules connected to ports 5 or 6 on the EX23-R can result in the MX modules losing sync with the eDAQXR/eDAQXR-lite until the EX23-R is reconfigured properly. Reconfiguring these ports is fairly trivial. Please contact HBM Support at support@usa.hbm.com if your test application requires using MX modules on ports 5 and 6.
- Push notifications on iOS devices. There is a known issue with the iOS HBM Push application, where notifications will not be pushed, but instead have to be fetched by closing or reopening the app on your iOS device, or performing a pull down refresh of the notification list.
- Setups utilizing multiple video channels from a multi-channel video encoder is not supported. Although the eDAQXR will allow the user to specify multiple video streams from a multi-channel encoder, using more than one channel from a multi-channel encoder is not supported, and configuring a test with this configuration may in not as-configured results, and is at the user’s own risk. It is recommended the user only use one channel on a multi-channel video encoder.
- Live video displays when using the Axis m7001 video encoder. The Axis m7001 encoder can be used, but there are limitations on video display capabilities with this old and now discontinued Axis product. Video frames will be properly stored in the SIE file; however, viewing of the video frames is supported in the Hardware view only. As such, video frames cannot be displayed when the SIE test is running.
