UE9 Firmware Revision History
Firmware is available on the UE9 Firmware page.
These firmware files require LJSelfUpgrade V1.24 or higher.
When updating UE9s with control firmware below 1.78 you must first upgrade to 1.78 before upgrading to newer firmwares.
Communications Firmware
V1.58: Fixed bug causing the comm buffer size to report the wrong value while streaming
V1.57: Fixed bug that sometimes caused the Single I/O command to fail when called repeatedly at high speeds
v1.56: Various bug fixes & optimizations to make TCP communication more stable
v1.50: Reworked how the UE9 manages memory and sockets allowing for more simultaneous connections via Ethernet
v1.41: (December 13, 2006) Initial TCP support for Modbus
v1.40: (September 29, 2006) Optimization & performance changes. Also fixed bug causing a subnet change to sometimes not
take effect.
v1.39: (June 19, 2006) Fixed bug causing DHCP settings to sometimes not take effect.
v1.38: (February 21, 2006) Fixed TCP problem with Mac OSX 10.4 not sending last ack and causing mem leak in sockets.
v1.37: (October 20, 2005) Fixed issue exposed by link problems over a wireless connection, that could cause the UE9 to reject
new TCP connections.
v1.36: (September 06, 2005) Fixed problem causing stream not to stop via USB on a PDA.
v1.35: (August 31, 2005) Added soft reset timer to commands sent via UDP.
v1.34: (August 18, 2005) Fixed USB issue when commands are executed while streaming. Changed internal command buffer
timeout to 750 milliseconds.
v1.33: (July 15, 2005) Changes to USB code to fix problem caused where commands were sent but could not be read caused by
a triggering a soft reset.
v1.32: (July 8, 2005) Changed USB detection to allow for faster power up.
v1.31: (June 21, 2005) Changes to USB code to recover from serious problems when partial commands are sent or read.
v1.30: (May 31, 2005) Soft reset timer implemented to flush buffers when partial or invalid commands are received.
Control Firmware
v2.26: Added overflow error codes to the UART RX buffer. Added support for timer clock source writes through modbus. Added
modbus addresses 6753 and 6703 (MIO port reads). SetDefaults will no longer clear the device name. Fixed a problem that was
causing the upper 16-bits of the counters to not increment. Changed the device name string to ASCII. Added 8-bit and 16-bit roll
protections to channel 210. Fixed an issue that could cause LabJack wrapped Modbus packets to become corrupted. 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. Fixed a bug
that was setting MIO0 low when calling stream config. Added functionality to read calibration and user memory through Modbus.
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).
