    Released: 2011-09-22

    New feature

  • Batch commanding applies wait for next command for faster execution.
  • If a power supply looses AC then an error is generated. If it never had AC then no error is generated (only a warning).
  • Error levels sent to communication interfaces can be configured independently to each port by a new command.
  • RS232 baudrate can be adjusted from Lightware protocol by {RS232BAUD=.....} command.

    • 3.2.2

    Released: 2011-11-23

    Bugfix

  • If the matrix was genlocked to signal from the test input and the signal got disconnected then there was a good chance that the matrix remained in genlock mode and made switches slowly (~2 sec lag).
  • Connecting an HDCP capable optical RX/TX to an MX-HDMI-OPT-IB/OB, noisy signal on the communication channel could cause fatal buffer overflow error and restarting of the router. In special cases the router could run an infinite restart loop.

    • 3.2.3

    Released: 2011-12-12

    New feature

  • Supports MX-3GSDI-IB.

    • Bugfix

  • There was a slight instability with the genlock function when bi-level or tri-level sync was used. Now every switch is in accordance with the corresponding SMPTE standards. (525i, 525p, 625i, 625p, 750p, 1125i, 1125p)

    • 3.2.5

    Released: 2012-02-20

    Bugfix

  • New standard timing descriptors are applied. Standard resolution list now contains 1024x768@60 and 1920x1080@60 resolutions.
  • Factory EDIDs had a bug - the digital sync was not set properly in the detailed timing descriptor blocks. Sometimes this caused error with analog sources.
  • MX-DVI-OPT-OB 2.0 outputs flashed when a laser enable command was sent to any port.
  • Preview output didn't convert down the deepcolor modes to HDMI 24bit in auto mode if the display didn't support deepcolor.
  • An extra 0-byte length short descriptor was present in the CEA data block. This may have led to incompatibility with some sources.
  • Analog 1920x1200p60 was not recognized due to enabled hsync dejitter filter and high sync detection threshold on the DVI-I board.
  • ASUS EAH3650 video card can send a strange analog format in 1280x720p60 and 1920x1080p60. These resolutions are added to the factory preset list now.
  • The 4-line LCD mismatched the 0dB and Auto EQ options in the MX-DVID-IB settings menu.
  • On the 4 line LCD at the "Switch EDID" menu item it is possible to select factory and user EDIDs, not just dynamic EDIDs.
  • Too many cached HDCP keys could lead to reboot.
  • If an EDID switch happens while the source is reading the data, then the input board could fail (MX-HDMI-IB, MX-DVI-HDCP-IB, MX-HDMI-TP-IB)

    New feature

  • Support for MX-FR33L
  • Pixel phase can be adjusted and saved with SMPTE compliant analog component/rgbhv incoming signals.
  • Saving and loading of a full matrix config is now possible. It can be controlled with the LCD menu (2 and 4 line LCD) and the lightware protocol.
  • Serial command passthru (receive and send) on MX-HDMI-OPT-IB/OB cards.
  • Control commands are not uppercased any more. This way lowercase characters can be used for example with serial command passthru and I/O names. Control commands should be still recognized with lowercase or uppercase characters.

    • Bugfix

  • Only the first two channels of mulitchannel PCM audio formats were passed by the router. Now up to 8 channels up to 192kHz are supported. Affected cards and ports: MX-HDMI-IB/OB, MX-DVI-HDCP-IB/OB, MX-HDMI-TP-IB/OB and CPU preview output/test input. When multichannel PCM is switched to an MX-HDMI-OB card, the front right and front left channels will be present on the SPDIF output connector.
  • Audio infoframes were lost when the display was turned off and on again (or removed and plugged in again). Affected cards and ports: MX-HDMI-IB/OB, MX-DVI-HDCP-IB/OB, MX-HDMI-TP-IB/OB and CPU preview output/test input.
  • SHUTDOWN time was invalid in some cases. now it's fixed.
  • Some displays (only known example is DELLU2410) didn't play audio correctly, if the signal was originated from an MX-DVII-HDCP-IB or an MXD-UMX-IB board. The problem persisted at 148.5/1.001 and 74.25/1.001 pixel clock frequencies.
  • The matrix rebooted after a while if a display continuously pulled the hot-plug up and down.

    • 3.2.8

    Released: 2012-06-01

    Bugfix

  • In the MX-FR80R during the boot sequence the matrix reported a missing PSU as an error. It was a false alarm because it is an error only when the PSU is removed during operation. This false alarm is fixed.

    • 3.3.0

    Released: 2012-08-16

    New feature

  • EDID reading is supported on both MX-HDMI-OPT-OB and MX-HDMI-OPT-IB card. Their behaviour is same as other cards now (dynamic edids, edid switching, etc.)
  • RS232 over fiber feature can be disabled per port basis. The default state is disabled. EDID is read only on the output port, if the serial passthru is disabled.
  • MX-HDMI-3D-IB and MX-HDMI-3D-OB are supported.
  • Omron SX51TX optical transmitter module (MX-HDMI-OPT-OB) has 0 default value for "waveform select" as this proved to result better performance on shorter cables.

    • Bugfix

  • Turning the laser quickly on/off on the HDMI-OPT-OB card from the controlsw resulted in connection loss with the HDMI-OPT- receiver device.
  • Sometimes random 0x03 charachters were sent to odd MX-HDMI-OPT-OB serial ports.

    • 3.3.1

    Released: 2012-10-19

    New feature

  • MX-DVI-OPT-OB-RCLK SCH_2.2 support
  • MX-3GSDI-IB now supports 3GSDI Level B signals: 1080p 50Hz and 60Hz

    • Bugfix

  • If an output was connected to "input 0" (disconnected), then it was switched to input 1 after a front panel-switching
  • If the LAN used Protocol#2 and RS232 used LW protocol, then the responses for the front panel switches were not sent to the RS232 port.
  • Connecting an output to input 0 (disconnected) when at least one dual link input card was present in the router may have caused fatal crosspoint switching error.
  • The Validity bit was set wrong in audio sample packets SB6 byte when PCM audio was transmitted. Affected cards: MX-HDMI-IB/OB, MX-DVI-HDCP-IB/OB, MX-HDMI-TP-IB/OB, Test input, Preview output.
  • If MX-HDMI-IB/MX-DVI-HDCP-IB/MX-HDMI-TP-IB/Test input was used, then the SPDIF outputs sent copyrighted (copy protected) material. Now the content protection is turned off on SPDIF outputs on the MX-HDMI-OB card.
  • When MXD-UMX-IB digitalized an analog audio signal, then the SPDIF stream was marked as professional application. This wasn't right for some professional SPDIF receivers.
  • MXD-HDMI-3D-IB/OB marked the digitalized analog audio as professional copyrighted material. Now it is marked as consumer non-protected material because this prevents some SPDIF interoperability issues.
  • Digital signals with <40px back porch had sometimes strange recolor effects with MX-DVII-IB and MXD-UMX-IB board.
  • If the MX-DVII-IB or the MXD-UMX-IB has been received HDMI YUV (444 or 422) signal and the user set the input video signal source with the :DVII command again to auto or digital mode (DVII command first parameter is S or D), then the image got greenish tint. This was because using incorrect YUV-RGB color conversion matrix.
  • If the MXD-UMX-IB has been embedded audio from the audio addon panel into the DVI/HDMI stream, and the user set the input video signal source with the :DVII command again to auto or digital mode (DVII command first parameter is S or D), then the image was blinking for a few seconds (and therefore audio was also muted for a while). This was because the TMDS clock was disabled while reapplying some settings. Now this flashing and audio dropout is eliminated.
  • MX-HDMI-3D-OB and MX-HDMI-3D-IB - several bugfixes related to test pattern modes, HDCP and infoframes.
  • If the IP address starts with 0 it is not displayed from now. e.g.: before this fix: "IP: 192.168.002.068" from now: "IP: 192.168.2.68"
  • DVIDL-IB EQ settins worked only for the first two output and port numbers were misindexed.
  • fixed MX-3GSDI-IB audio crosspoint initialization, audio channel status and audio infoframe content.
  • MX-HDMI-3D-IB didn't work well with 4x20 character LCD display

    • 3.3.2

    Released: 2012-11-12

  • The serial number of the CPU and I/O boards are saved to the SD card log during the boot process.

    • 3.3.4

    Released: 2013-01-28

    Bugfix

  • The image was shifted one pixel to the right with digital signals. Affected cards: MX-DVII-HDCP-IB, MXD-UMX-IB

    • 3.3.5

    Released: 2013-03-04

    Bugfix

    Released: 2013-05-23

    New feature

  • MX-TPS-OB, MX-TPS-OB-A, MX-TPS-OB-S support (incl. serial passthru and ethernet functions)
  • MX-TPS-IB, MX-TPS-IB-A, MX-TPS-IB-S support (incl. serial passthru and ethernet functions)
  • File uploading to SD card through Lightware protocol. (needed for TPS fw upgrade)

    • Bugfix

  • The LCD screen didn't show the analog audio options for the MX-HDMI-3D
  • If a dynamic EDID memory slot had been empty and new EDID was read from one output, then the output validity table was showed as being invalid EDID after reading the EDID header until the first reboot.
  • The audio sample frequency was unstable at 1080p60, this may have resulted crunches on the S/PDIF output with DVII input.
  • HDCP keycounter sometimes resulted with 0 key with certain devices due to a short timeout. Now this is fixed.
  • The MX-DVII-IB and the MX-UMX-IB boards sometimes didn't detect the 36 bpp - 24 bpp deep color change, and remained in 36bpp mode.
  • MX-DVII-IB, MXD-UMX-IB: SPD Infoframe was sent with wrong header, could cause issues with deep color signal. Stored settings block was too large on these cards.
  • If an MX-HDMI-3D-IB card was present at the 1st input slot and any output was connected to the 0th input (ie. disconnected), then the matrix has coninously rebooted.
  • A noisy incoming signal may disable input ports on MX-HDMI-IB, MX-DVI-HDCP-IB, MX-HDMI-TP-IB and CPU test input (signals were detected appropriately but not forwarded to the crosspoint). The only solution was to restart the whole router, however the issue has appeared very rare. This issue is fixed now.

    • 3.3.7

    Released: 2013-08-22

    New feature

  • Temperature sensor readbacks on the MX-TPS-IB/OB cards.
  • Logfile reading speed has been increased a lot. LAN connection speed is around 5kbyte/sec , while the RS232 port utilizes the full bandwidth (depending on the actual baudrate)
  • Errorlevel handling is modified: recoverable issues will not display on the LCD and they will not trigger the alarm LED.
  • Ethernet can be disabled or enabled per port basis on TPS-IB/OB cards
  • HDBase-T HDCD database is used to recognise remote devices
  • The minimum assertion time for hotplug line is 1.5 sec on the MX-HDMI-IB, MX-HDMI-TP-IB, MX-DVI-HDCP-IB, MX-DVII-IB, MXD-UMX-IB, MX-HDMI-3D-IB (and variants), MX-TPS-IB (and variants) cards and test input port. This is 15 times greater than the required minimum by the standard. The intention of this extra long HPD pulse is prevent the non-standard devices to miss the hpd event.

    • Bugfix

  • A false "SBTB error" message has appeared on the LCD screen after boot if at least one MX-DVIDL-OB card was installed in the frame. This issue persisted only with 3.3.6
  • Changing audio mode on a port could have an effect on the adjacent port's audio mode. Affected cards: MX-HDMI-3D-IB, MX-HDMI-3D-OB, MX-TPS-IB, MX-TPS-OB.
  • When the source stopped sending audio in HDMI stream, the ports did not detect it correctly in some cases, and still reported embedded audio. Affected cards: MX-HDMI-3D-IB, MX-HDMI-3D-OB, MX-TPS-IB, MX-TPS-OB
  • Factory default test pattern changed from solid black to color bar. Affected cards: MX-HDMI-3D-IB, MX-HDMI-3D-OB, MX-TPS-IB, MX-TPS-OB
  • Deep color problem with DELL U2410 fixed. Affected cards: MX-HDMI-3D-IB, MX-HDMI-3D-OB, MX-TPS-IB, MX-TPS-OB
  • When an HDMI 1.3 output was muted after receiving deep color signal, low resolution signals (below 41 MHz TMDS clock) was not detected by the port after unmute. Fixed. Affected cards: MX-HDMI-OB, MX-DVI-HDCP-OB, MX-HDMI-TP-OB, MX-CPU2 (Preview output).
  • When no embedded audio was present on a port, noise was detected on S/PDIF outputs, which were used to deembed audio. Fixed on MX-HDMI-3D-IB-S, MX-HDMI-3D-OB-S, MX-HDMI-OB, MX-TPS-IB-S, MX-TPS-OB-S.
  • SPDIF clicking/popping noise bug fix. When there was no audio sample packet in the stream (but ACR packets were still present), the MX-HDMI-OB, MX-DVI-HDCP-OB and preview output have sent a 53Khz invalid SPDIF signal. This caused a clicking noise with some AV receiver.
  • Audio embedding fixed (it failed in some cases, when the user changed Audio mode to Embed from aux audio). Affected cards: MX-HDMI-3D-IB, MX-HDMI-3D-OB, MX-TPS-IB, MX-TPS-OB

    • 3.3.8

    Released: 2013-10-01

    Bugfix

  • PWR_x commands responded "Invalid command" if sent to frame that is smaller than 80x80. These commands are only valid for the 80x80 frame.
  • If input signal was present on a SII9575 port and test pattern mode was changed from "Off" to "No signal mode", SII9575 output had been turned off for a short period unnecessarily. Fixed. Affected cards: MX-HDMI-3D-IB, MX-HDMI-3D-OB, MX-TPS-IB, MX-TPS-OB.
  • Deembedded audio outputs (analog, S/PDIF) become stable more quickly after input signal is changed. Affected cards: MX-HDMI-OB, MX-TPS-OB-S, MX-TPS-OB-A, MX-HDMI-3D-OB-S, MX-HDMI-3D-OB-A.
  • Firmware v3.3.7 sometimes rebooted with 2 or 4 line LCD display.
  • The cycle testpattern has stopped sometimes for a few minutes.
  • If an error happened during the booting process, there was no alert displayed on the LCD screen (however the event has been logged).
  • If the errorlog menu was active on the 4-line LCD screen, then a new incoming alert may confuse the lines on the LCD screen.
  • Lightware simple protocol mode (P_3) could hang if an unknown command had been received.
  • When the USB connector was used from the Matrix Controller software, every incoming charachter was capitalized. This lead to unexpected results while using the ROF (RS232 over fiber / TPS) commands.
  • Error log downloading over USB was bugous.

    • 3.3.9

    Released: 2013-10-22

    Bugfix

    • Bugfix

  • The serial port extension sometimes transmitted/received bugous data on the TPS boards.
  • If one or more MX-TPS-IB or MX-TPS-OB (including audio addon versions) were installed in the frame, sometimes a false flashing "PCA9673" error appeared on the LCD screen.
  • When DVII input board was used with MX-HDMI-3D-OB or MX-TPS-OB, the output ports could measure strange resolution or could not detect the incoming signal, if the DVII input changed from no sync screen to incoming signal. Fixed.
  • Green sparks could appear in the output signal of MX-HDMI-3D-OB, if the input signal was coming from MX-HDMI-3D-IB and was switched between 1080p and 480p by the crosspoint.

    • 3.4.1

    Released: 2014-03-31

    Bugfix

  • Some monitors that do not terminate the TMDS lines in standby mode, could not wake up from this state, when input signal was connected through MX-HDMI-3D-OB or MX-TPS-OB. This issue is now fixed by powering up the output ports not only when TMDS termination is present, but also after a hotplug event. Affected cards: MX-HDMI-3D-OB, MX-TPS-OB.
  • 4line LCD - View EDID menu froze the LCD task if there were no IO cards in the matrix.
  • 4line LCD - FR80 - View EDID did not show the 81st input and output.
  • 4line LCD - View EDID - Dynamic EDIDs was not displayed if there were no input cards in the same numbered slot (the problem was checking the input cards instead of the output cards)
  • Too long lines in the error log may have disrupted the log reading if special charachters were used.
  • The text of the test pattern generator clock menu on the LCD screen was disambigous.
  • There was no error message if SX51 was configured to SX4.
  • 4-line LCD - The S/N number of the output cards were not shown in the card information menu.

    • 3.4.4

    Released: 2014-10-08

    New feature

  • UMX-TPS devices handle the command channel even in disabled receive mode, serial packets are discarded.
  • IP configuration via RS-232.
  • Logging data extended, if VS100 holds I2C SCL line down. VS100_getHpdStatus function added (previously this register was checked in handler periodically, but it was removed in order to reduce the number of remote read transactions to prevent VS100 I2C lockdowns).

    • Known bug

  • HDCP signal is visible for a few seconds after booting on non-HDCP compliant monitors.

    • Bugfix

  • TPS write functions fixed in disabled receive mode.
  • VSNACK and SII9575 errors fixed on MX-TPS-IB and MX-TPS-OB.

    • Bugfix

  • Plugging a monitor into the FR80's Preview Output caused reloading of factory default EDID to all inputs.
  • Alphanumeric charachters in the factory EDIDs (like display name field) were not padded properly.
  • Factory default IP can be set with controlboard buttons.
  • Factory EDID revision number has been set to 1.3 instead of 1.4 now. This may prevent compatibility issues (usually the source didn't see the connected device as audio capable) with old graphics card drivers.
  • Analog YUV support has been removed from the basic EDID structures of factory EDIDs.
  • From now on MX-DVII-HDCP-IB and MXD-UMX-IB cards always send 24bpp signal into the crosspoint switch. The 36bpp signals caused signal integrity problems in some rare conditions which could result in audio popping noise.

  • If the temperature of the TPS or TPS2 card increases above 80C, it is logged into the SD card.
  • Added support for MX-3GSDI-IB v20.

    • Bugfix

  • Some residual power from the output cards (from the connected sink devices) could keep the CPU alive in MX-FR80 and MX-FR65 frames even after removing the AC cords. This resulted false alarms on the LCD and in the log files. This condition is detected and handled now.
  • MX-HDMI-3D-OB and MX-TPS-OB could not handle if one of the DDC lines was broken. It could cause VTASK RESET and SII9575 errors. Fixed.
  • MX-FR80 logged a false "MTRI setXpoint" error after crosspoint switching.
  • Improved error notifications on the 2 and 4 line LCD.
  • AVI Infoframes were set improperly on MX-3GSDI-IB. This caused random video drops with some displays.
