Change Log

  • Added LED power modes and LED control registers.

 

Changes:

  • DIO_ANALOG_EN will now set lines being changed from analog to digital, to input.
  • STREAM_CLOCK_SOURCE will no longer return an error when being set to zero.
  • SBUS will now default to using FIO4 and 5. 
  • Changed the read mechanics for DIO_EF indices 3 and 4.
  • Some DIO_EF functions were only set up to work with the T7. Those have been updated to work with the T4. 
  • An error will now be thrown when attempting to change the index of an enabled DIO_EF.
  • DIO_EF interrupt counter will now maintain two counts. One for rising edges, the other for falling.
  • Updated Comm LED to idle off before the first enumeration.

 

Fixes:

  • Fixed startup configuration bugs.
  • Fixed a bug in DIO_EF indices 3 and 4 that was causing invalid data.
  • Fixed a bug in asynch that could cause data corruption when using parity.
  • Fixed a bug that could cause stream auto-recover to report a partial packet. Change special range threshold from 0.01V to -0.005 V.
  • Changed stream resolution limit to 5 in both stream and C-R.
  • Fixed a bug that was preventing Ethernet from starting up properly when being reset without a power cycle.

How to Upgrade T-Series Device Firmware

To upgrade the Firmware of a T-Series device (T4, T7), open the device in Kipling and navigate to the "Device Updater" tab.  Then select the appropriate firmware version and press "Download and Update":

Update LabJack T4, T7 Firmware using Kipling

If the update fails, it may be necessary to download and install the latest beta LJM installer.  If this fails, it may be necessary to use the functionality of one of the SPC jumper/reset pins.  If your device is no longer working correctly or further assistance is required, contact LabJack Support as we have a few additional Windows utilities that may be able to help upgrade a device's firmware or recover a bricked device.
