UE9 Firmware

UE9 Firmware Overview

These firmware files require LJSelfUpgrade V1.24 or higher. The UE9 has two internal processors, a communications processor and a control processor, we recommend keeping both up-to-date with the current firmware.

When updating UE9s with control firmware below 1.78 you must first upgrade to 1.78 before upgrading to newer firmwares.

Fixed an issue causing special channels called through single IO to return an erroneous values in the lower data byte. Added Modbus support for analog channels above 129. Added support for special analog channels greater than 192 to Modbus. Added 1-Wire support. Fixed a problem that was causing SingleIO to treat CIO3 as open-collector. Added a bus idle check to I2C.

v2.11: (April 29, 2010) Added z-phase support to quadrature timer modes. Added special stream channel support to normal command-response analog functions. Added an option to reduce the SHT clock speed. Modbus packets over USB will now clear the watchdog. ControlConfig reads will now display DACs as enabled. Legacy support for setting defaults through ControlConfig has been finished. Time mode, StopTimer, has been fixed (Stopped working in beta 1.98).

v2.04: (December 10, 2009) Modbus support updated. Timer code updated. Added extended watchdog support. Added extended startup default system. This version is required for all UE9-Pros sold after Dec. 10, 2009.

v1.81: Feedback no longer resets the quadrature count.

v1.78: (April 6, 2007) Added functionality to allow the lower 32-bits of the system timer to be read while streaming.

v1.76: (February 22, 2007) Improved 32-bit edge measurements. Fixed analog noise issues introduced in 1.70.

v1.64: (August 10, 2006) Added functionality to Stop Timer (mode 9) such that updating the Value of the stop timer re-enables the stop timer and the adjacent timer.

v1.62: (July 5, 2006) Fixed a couple issues with the logic that detects bad stream scan rates.

v1.61: (July 3, 2006) Fixed an error that was occurring when using the duty-cycle input timer.

v1.54: (February 4, 2006) Fixed a problem where spurious AIN readings could occur when sampling a midscale voltage in a stream with resolution greater than 12.

v1.52: (January 17, 2006) Cleaned up MIO behavior when using extended channels. Added SPI function.

v1.51: (December 15, 2005) Fixed problem where streaming did not work if first channel in the scan was a timer/counter. Fixed DAC update option in the Watchdog function. Fixed problem causing possible errors in timer modes 2 & 3. Fixed problem where an initial edge was caused immediately in external triggered stream, if the trigger line was initially low.

v1.50: (November 14, 2005) Fixed AIN noise problem introduced in v1.48.

v1.49: (November 7, 2005) Added DAC update to watchdog function.

v1.48: (November 2, 2005) Fixed DAC disabling so they are actually disabled when instructed to do so. Fixed issue introduced in v1.46 where a single channel stream would always measure ground.

v1.46: (October 17, 2005) Changed stream mux behavior so that the user does not have to take any special precautions to keep a floating channel from affecting valid channels. Changed enable/disable behavior of DACs. If Feedback is called and the enabled bit is set for either DAC, then both are enabled. If SingleIO is called for either DAC, then both are enabled. The only way to disable the DACs is by calling Feedback with both DAC enabled bits clear.

v1.45: (October 5, 2005) Changed command/response mux behavior so that the user does not have to take any special precautions to keep a floating channel from affecting valid channels.

v1.44: (September 26, 2005) Fixed problem where calling command/response function (Feedback) during stream, could cause glitches in the streamed analog input values.

v1.40: (August 4, 2005) Added full timer read capability to stream. Stream channels 200, 201, 202, 203, 204, and 205 read the low words of their respective timer modules and capture the high word. Channel 224 reads the most recent capture. Fixed a PWM glitch where the pin would float for a few micro seconds when stopped. Changed stream to enable timer on stream start. Fixed the timer Stop modules which were broken by the PWM glitch fix.

v1.38: (July 13, 2005) Fixed a bug that was causing slave stream to falsely return a scan overlap error. Special channel numbers changed to 200 and 225. v1.39: Changed the way the timer updates in an attempt to eliminate the PWM first cycle long low time. (July 21, 2005)

v1.37: (July 12, 2005) Added special stream channels to read quad.

v1.36: (June 24, 2005) Added FeedbackAlt.

Hello,

Your firmware history suggests I need version 1.41 for Modbus TCP support. This is supported by the error msg I got trying to connect to a 1.40 level device using Modbus TCP. However, the download is not available on the download site. How do you advise I proceed to obtain the right firmware?

Thanks,

Dean

Newer Comm firmware versions than 1.41 can be found here.

Thanks -- I note that is Beta -- is that OK? I have 1.40, I'm told I need 1.41, but the beta code is 1.43. Is 1.41 just not available now?

Thanks!

Dean

1.41 is the first version we added that support, but 1.43 has a few bug fixes in addition to that.  Thus, 1.43 should work just fine.

Thanks!
