Every DHD software application which exchanges data with a device or a software, needs the DHD Communication Server (DHDCS) for this communication. This software administrates the entire communication between DHD systems in the network and the related applications on the PC. Each DHD application in the following list contains an entity of the DHDCS, which is extracted on the start of the application, in case no DHDCS or an older [...]

You can set the properties of the peak program meters of the TFT displays with the aid of the Toolbox4 / Toolbox5 configuration software. Choose the according device in the project tree of the Toolbox, open the sub-branches of the "Logic System" entry and select "Level Detection". Please enter the following values to emulate an analog peak program meter with an integration time of 10 ms, according to the standards [...]

The DHD Communication Server (DHDCS) does not save the filter settings (DHDCS > "Options" menu > "Filter Settings" tab). That means, after restarting the DHDCS all filter options are deselected. This is done for security reasons, so that possibly occurring error messages and other important messages will not be suppressed permanently.

The faders (Penny & Giles PGFM3200/-/M/-/E/I/Z/X, Specification D460667) of the modules RM420-020MW and RM420-029MW need to be calibrated. This is already done by DHD during the manufacturing process. Calibrating is especially important after changing the faders of the modules RM420-020M and RM420-029M from "plastic" faders (Penny & Giles PGFM8100/D/M/----/F, Specification D468105) to "metal" faders (Penny & Giles PGFM3200/-/M/-/E/I/Z/X, Specification D460667). Proceed as follows for calibration of the fader modules: Move [...]

If you update your RM4200D to the Series 52 firmware generation, it is necessary to exchange the Communication Controller. Instead of the RM420-850, you need an RM420-852/853 controller module. If your console contains a TFT display, you need to rewire it after the controller exchange. The following diagram shows the conventional wiring of the TFT screen of an RM4200D console equipped with an RM420-850 Communication Controller. Click on the diagram [...]

Please find all fiber-optic cables in the following PDF file, that are siutable to use with DHD MADI modules and which cable type can be used for the individual modules. Fiber Optic Cables

In general it is possible to replace the fader knobs of the RM4200D fader modules with coloured knobs. However, this is not possible for modules with motorized faders. The fader knobs of the motorized faders need to be conductive to be able to recognize fader touches. These conductive fader knobs are currently only available in silver.

A contextual menu appears if you right-click on a device in the DHD Communication Server. In this menu you can activate and deactivate the logging for the selected device. Depending on the DHDCS version, several Log Levels might be provided in this menu. However, these options are greyed out (not useable) for RM4200D devices (Toolbox4 firmware generation). The various Log Levels can be used for the logging of 52/RM4200D (Toolbox5 [...]

The RM420-015B replaces the RM420-015. All orders will be changed automatically. The only difference is the power supply. The RM420-015B is supplied by Power over Ethernet using a power supply with integrated Power over Ethernet inserter (PSA16U480POE). The socket for the 48V power supply at the display is removed. If you order a 52-4015A, a 52-3015A and a PSA16U480POE together, you will receive the same hardware kit as in item [...]

DHD Software might not run correctly under Windows 7 right away. This may particularly apply to software like Toolbox4/Toolbox 4.5. In order to be able to use the software anyway, it is necessary to change the compatibility settlings for the program. Right-click the program icon, hit Properties, and then click on the Compatibility tab. Activate "Run this program in compatibility mode for:". Select "Windows XP (Service Pack 3)". Activate "Run [...]
