13.10. Firmware Release Notes
Below list shows the released firmware packages with important
notes.
v1.6.0b10
Release date: 2020-01-27
Bugfix:
▪ Fixed a bug that resulted in multiple Hardware version lines for
the same hardware in the LCD menu.
▪ Fixed a bug that caused some settings of the DisplayPort input
to be lost thus their values not to be stored.
▪ Fixed a bug that prohibited presets from being saved or recalled
from the front panel LCD screen on matrix variants without
control panel keys.
▪ Improved on the reliability of device upgrade.
Known issue:
▪ Swing and pre-emphasis values might not be rendered correctly
on the graphical user interface.
▪ If the DisplayPort input stream has no embedded audio and it
is routed to a DisplayPort output, video signal stability issues
(blinking) may arise on the output. Furthermore, when embedding
audio in such streams on the input, video signal instability may
also be accompanied with audio popping on the output. The
issue can be eliminated by repeating link training on the input.
▪ The USB interface will not work when an USB cable is connected
to the USB port on a matrix variant with 32 or more input and
output ports during booting.
▪ The support for some audio formats might get removed from the
EDID read on DisplayPort outputs.
▪ Color space information on the graphical user interface might
not be accurate for the DP outputs.
▪ DisplayPort related forced settings (e.g. DpForcedMode) on the
output DisplayPort board are preserved after restoring the matrix
to factory defaults.
▪ The signal on a DisplayPort input might not get recognized (and
consequently, not routed to the selected output) after the matrix
is restarted. Triggering a new link training on the input resolves
the problem.
MX2-HDMI20 series – User's Manual
v1.5.1b5
Release date: 2019-11-11
Bugfix:
▪ Fixed a bug that resulted in no embedded audio in the HDMI
stream on HDMI only output boards after resetting the matrix to
factory default settings.
▪ Made improvements to manufacturing.
v1.5.0b6
Release date: 2019-10-11
New feature:
▪ Added support of MX2-48x48-HDMI20-A-R, MX2-32x32-HDMI20-
A-R and MX2-32x32-DH-16DPi-A-R devices.
Bugfix:
▪ Fixed a bug that caused the upgrade of certain MX2 variants to fail
when the device was set to a fix IP address.
▪ Fixed a bug that presets were ordered on the LCD menu randomly.
Now they are ordered in a numerical order.
▪ Fixed a bug that made impossible saving new presets from the
front panel buttons.
▪ Fixed a bug that made preset names unreadable on the LCD screen
if there were more than six presets saved.
▪ Fixed a bug that caused HDMI 5V being low on the outputs after
a firmware upgrade. This issue was happening only until the first
reboot after upgrading the firmware.
▪ Fixed a bug that caused incompatibility between RCP control
panels and matrices while using P#2 protocol.
▪ Fixed a bug that caused not fetching new IP address from the DHCP
server when Ethernet cable was removed and plugged again.
Applied firmware package: v1.7.0 | LDC software: v2.5.1b5
v1.4.2.b11
Release date: 2019-07-23
Bugfix:
▪ Fixed a bug that caused MX2-8x8-HDMI20-Audio (part number:
91310033) not to pass an input video signal of 4k@60Hz 4:4:4.
▪ Audio port submenus next to DisplayPort input ports were
missing on the LCD screen in variant MX2-24x24-DH-12DPi-A-R
▪ Routing video signal from input 6 to output 6 and output 13 was
unstable when the internal temperature has reached about 35-
40 C. The issue was affecting only MX2-16x16-HDMI20(-AUDIO)
(-R), MX2-24x24-HDMI20(-AUDIO)(-R), MX2-16x16-DH-8DPi-A-R,
MX2-24x24-DH-12DPi-A-R and MX2-24x24-DH-12DPi-R variants.
▪ Fixed a bug that might have resulted in unusually long or failed
upgrade.
▪ Fixed a bug that might have resulted in some components not to
be upgraded properly during firmware upgrade.
▪ Input and output port firmware upgrade has been failed in
MX2-8x8-HDMI20-AUDIO and MX2-8x8-HDMI20-AUDIO-L
variants with v1.4.1 firmware.
▪ Firmware upgrade has been failed in some rare cases.
▪ Displayport input cards have truncated 10 and 12 bit deep color
signals to 8 bit in every case.
v1.4.1b1
Release date: 2019-06-13
Bugfix:
▪ Fixed a bug that caused a DisplayPort input port not to send EDID
information to the connected video source after a cold boot.
EDID communication was OK after the input was switched to a
different output.
