Chapter 1: Introduction Overview AJA's 4K2HD downconverts professional SDI 4K/UHD signals to HD resolution using AJA's high-quality scaling for cost-effective monitoring and conversion. 4K2HD’s HD-SDI and HDMI outputs are both live all the time, producing fantastic-looking HD images for on set monitoring or direct-to-air broadcast. 4K2HD supports high frame rate (HFR) 4K inputs at 50 and 60fps and converts the HD output to 50 and 60fps for accurate viewing.
Default Operation NOTE: The 4K2HD auto configures to the connected inputs. The auto-configure function identifies the connected inputs and generates the default outputs for the given input. Default operation can be overridden and set manually using AJA’s MiniConfig application. Signal conversion requires the presence of a valid SDI video signal on the SDI IN 1 BNC. For single SD or HD inputs, BNC input 1 is the default input. For dual-link 1.

Installation Typically, 4K2HD installation consists of the following steps: 1. Ensure the 4K2HD is disconnected from power. 2. Connect video equipment to the converter BNCs and HDMI connector. 3. Apply power to the converter (AJA power supply included). 4. The 4K2HD will now run using the default factory settings. If you wish to alter the factory settings, you’ll need to: • Install the AJA MiniConfig software on your computer. • Attach the 4K2HD via USB. • Make your changes using MiniConfig setup screens.
Chapter 2: Operation USB Control and Setup—Using AJA MiniConfig The 4K2HD can usually be used right out of the box for most applications since it is designed to recognize inputs and perform standard actions automatically by default. However you can also manually configure the 4K2HD using a supplied software application for PCs and Macs called “MiniConfig.” This same application can be used to update Mini-Converter firmware released by AJA.
NOTE: On a Mac, when the Mini-Converter is connected to the USB port, you may see an alert like that shown following. If you do, press Cancel—this alert can be ignored. Figure 4. Mac Network Message (ignore) PC Startup: To run MiniConfig on a PC, find the AJA MiniConfig in the program list and locate the AJA MiniConfig application. Figure 5.
Running Multiple MiniConverters: MiniConfig can manage multiple AJA Mini-Converters connected via USB—even when they are of differing types. However it only connects to one at a time. You can choose which Mini-Converter you wish to control using the pulldown menu in the upper right hand corner. If you want to configure and update multiple Mini-Converters in parallel, you can do it by running multiple instances of the MiniConfig application and have each control a different Mini-Converter. Figure 6.
Any parameter changes you make are immediately implemented and are saved, overwriting previous settings. Input Tab Screen Click on the Input tab to view and make changes to the converter’s input settings. Figure 7. MiniConfig, Input Tab Screen Input Video Selections Video Source: Selects the input video format. Choose from the following: • Auto - automatically selects the format based on the input video parameters.
Video Format: 3G-B Mode: Selects the Input Video Format. Choose from Auto, Progressive, Interlaced, or PsF (progressive segmented frame). Choosing “Auto” automatically selects the format based on the input video parameters and the payload ID. Selects the 3G level B Video Mode. Choose from the following: • Auto - automatically selects the format based on the input video parameters. • Dual Link - select this when the input is Dual Link.
SDI Out Passthrough: 3Gb Mode: HDMI Tab Screen Choose Auto, Off, or On (default is Auto). This setting can be used with HD or 2K psf format input signals. When On, psf format will passthrough to the SDI output instead of the converted, progressive format signal. Choose Auto, 3G-A, or 3G-B (default is Auto). Click on the HDMI tab to view and make changes to the 4K2HD HDMI output settings. Figure 9. MiniConfig, HDMI Tab Screen Color Space: Selects the desired output video format.
Audio Tab Screen Click on the Audio tab to view and make changes to the 4K2HD audio settings. Figure 10. MiniConfig, Audio Tab Screen Audio Selections Input Source: HDMI Channel Count: Choose which embedded audio channels are routed to the HDMI output. Eight channels are routed at a time. You can choose Ch 1-8 or Ch 9-16 from any SDI input. Choose Auto, 2 of 8 channels or 8-channels embedded audio. Choosing “Auto” automatically selects the audio channels based on the attached device's capabilities.
Update Tab Screen Use this Update screen to view the software version currently installed on the converter or install new software. Figure 11. MiniConfig, Update Screen NOTE: When discussing Mini-Converters, “Firmware” is software that will be stored in the MiniConverter’s non-volatile memory and used when it is powered up. This is something different than the MiniConfig application software. The version numbers shown in the Update screen refer only to the firmware.
Progress will be shown via the Progress thermometer bar, and when completed an “Update Succeeded” message appears. Info Tab Screen This screen provides basic information about the Mini-Converter. This information is mostly useful when calling AJA Support for service or technical support. Figure 12. MiniConfig, Info Screen Name: Type: Assembly: Serial Number: 4K2HD v1.7 This field allows you to give your Mini-Converter a name.
