Supporting HDMI 2.0, HDCP 2.2, up to 4K video resolution, and up to 10.2 GBPS bandwidth. This switch allows any source (Blu-ray, UHD Blu-ray, satellite receiver, game consoles, PCs, etc...) to be shown on any of the connected displays.This matrix equalizes and amplifies the output to ensure the HDMI signal can be transmitted through long HDMI cables without loss of quality. You can extend your distance further with the AC-EX70-UHD HDMI Extender. Full EDID management allows maximum flexibility with todays wide mixture of sources and displays.This is an ideal solution for digital entertainment centers, HDTV retail, show sites, data centers, schools, conference and training centers and more!Features:•HDMI 2.0 (10.2 GBPS)•HDCP 2.2 compliant•De-embed 2CH audio on each output •Independent source/display switching •Up to 4K Resolution (4K60 4:2:0)•HDR Supported•IR & RS-232 Control Easy to use:•Install in seconds •Feature rich•Powerful EDID management •Front Panel Control•IR Remote•IR & RS-232 Control•LAN ControlDevice Overview:Figure 1 ~ AC-MX44-UHD Panel ControlsNOTE: There is an application diagram on page 11 of this manual.In The Box:•AC-MX44-UHD Matrix Switch •IR Remote Control •IR Extension Cable•12V/3A Locking Power Supply •Instruction ManualQuick Installation:1.Connect the HDMI input sources (Blu-ray, Set Top Box, etc...) to the AC-MX44-UHD2.Connect the HDMI output devices (AVR, Display, Distribution Amplifier, Extender) to the AC-MX44-UHD3.Power on the sources4.Connect the power supply into the AC-MX44-UHD5.Turn on output devices/displays6.You may now use the front panel controls, supplied IR remote or free PC software to control the switch.* For advanced programming please see the RS-232 commands on page 7Front Panel Control:The AC-MX-44-UHD front panel controls allow for the selection of the inputs to the various outputs. First press a button on the OUTPUT row to choose the output port, then press a button on the INPUT row to select the input signal for the selected output. (Output, then Input)Select Output First --><-- Then Select Your InputIR Remote Control:The HDMI routing of the matrix can also be controlledby using the IR remote supplied with the product.The left arrow button decrements to the next lowerinput port, and the right arrow increments to thenext input port.The IR remote controller for the AC-MXDH-44 alsoallows direct selection of the inputs for each output.Figure 2 ~ AC-MX44-UHD IR RemoteAdditionally, the supplied IR Extension Cable can provide a different receiver position. Just plug into the IR Extension Socket on the back of the matrix and place the receiver in a more convenient location.Figure 3 ~ AC-MX44-UHD IR Controls Figure 4 ~ IR Extension CableBonus Feature!Pressing and holding the any OUTPUT button will automatically read, store and apply the EDID from the display device to the current INPUT assigned. It will be stored in USER EDID 1.EDID Management:This matrix has 12 factory defined EDID settings. It also has 3 user defined EDID memories. The user EDID memories are independent to each input and can be set differently. The user defined EDID can be uploaded using the free PC Control software or RS-232. In addition, you can choose to read the EDID from the desired output and that read EDID will automatically store and overwrite the EDID in "USER EDID 1". We recommend uploading custom EDID settings to memory 2 or 3.By default the matrix is set to a 1080P EDID, this is to maximize plug and play capability. When using 4K sources, you will want to define a 4K EDID on that input (or read from the display).To Change the EDID setting:1.Press and hold the INPUT you want to change for 3 seconds2.Now "click" desired INPUT to toggle through the available EDID options3.Once you are on the EDID you want to select, press and hold for 3 seconds again. This will set the EDID for the desired input. Please see the example below for detailed instructions.These are the pre-defined EDID settings that you can toggle through:1 - 1080P 2CH (PCM)2 - 1080P 6CH (5.1 Channel)3 - 1080P 8CH (7.1 Channel)4 - 1080p 3D 2CH (PCM)5 - 1080P 3D 6CH (5.1 Channel)6 - 1080P 3D 8CH (7.1 Channel)7 - 4K30Hz 3D 2CH (PCM)8 - 4K30Hz 3D 6CH (5.1 Channel)9 - 4K30Hz 3D 8CH (7.1 Channel)10 - 4K60Hz (Y420) 3D 2CH (PCM)11 - 4K60Hz (Y420) 3D 6CH (5.1 Channel)12 - 4K60Hz (Y420) 3D 8CH (7.1 Channel)U SER EDID 1 USER EDID 2 USER EDID 3EDID from output 1 EDID from output 2 EDID from output 3 EDID from output 4EDID Management Cont:The first 12 EDID settings cannot be altered. The three USER EDID settings are programmed using RS-232 or the free PC Software. However, you can read an EDID from any output and it will automatically store in USER EDID 1. Remember, each IN P UT has an independent EDID setting and you may need to program each one.To read and set an EDID to a specified input the steps are the same as on PAGE 5. The only difference is that when you see a screen similar to FIGURE 5, you press and hold the INPUT button again for 3 seconds and this AUTOMATICALLY reads, stores and sets the EDID for that INPUT.Figure 5 ~ Read EDID ScreenDisplay IP Data:Press and hold INPUT 3 and INPUT 4 at the same time for three seconds to display the current IP settings. This screen will change every 3 seconds showing additional settings (host, net mask, router IP). NOTE: This screen always starts with the current IP address of the matrix:In order to prevent potential IP problems, most IP settings have to be managed in the Free PC Software or using RS-232 commands.NOTE: The default IP address is 192.168.001.239 (As pictured above)You can enable/disable DHCP mode directly from the front panel. When DHCP is enabled it will automatically gather an IP address from the network and it will be discoverable on said network. You can now view the assigned IP address by following the steps above. To toggle DHCP, press and hold INPUT 1 and INPUT 3 at the same time for three seconds. You will see this:Cascade Mode:When Cascade Mode is turned on, the signal is passed from the switch without reading EDID or HotPlug. Many issues can be resolved in the field with this mode, including:•Invalid/incorrect EDID coming from display (It happens more than you think)•When you want to manage EDID in a device further down the chain (AVR or Distribution Amp)•When running one or more outputs into additional peripherals before the displayWe recommend you ONLY use cascade mode if you have exhausted all other troubleshootingoptions. To toggle Cascade Mode press and hold INPUT 1 and INPUT 2 at the same time for three seconds. When Cascade Mode is enabled you will see this:AC-MX44-UHD and AC-MX88-UHDThe same commands can be sent to the matrix using Ethernet as IP commandsdiagram at the end of the manual.NOTE: HDR (High Dynamic Range) is supported on these matrix switchers. you mus read EDID from and HDR capable display and store it to to the input where the HDR source resides.Specifications:After Sale Service:AVProConnect.Application Diagram:RS-232 Wiring Diagram:Audio Wiring Diagram:Using the Free PC Software: General Matrix ControlUsing the Free PC Software: EDID ManagementUsing the Free PC Software: IP SettingsAVP roC o nn e ct 3518 N Casco A v e nu e ~ S ioux Fa l l s , S D 57104 1-877-886-5112 ~ 605-274-6055su p por t @a v p r o c o n n ec t.c o mThank you for choosing AVProConnect!Please contact us with any questions, we are happily at your service!。
