What’s new in v1.4 of the NDI Router

There are three main new features in v1.4 of the ZEN NDI Router, multiple instances, clearing outputs and editing NDI output names.

1) Multiple instances allows several copies of the router to be run simultaneously on the same PC, potentially extending the numbers of NDI sources and routed outputs which can be switched. Each instance is assigned a different port number and can be controlled remotely via the Router Protocol, as used by the accompanying Router Remote app (which controls a single instance) and a new Preset Remote app which can switch the Presets on multiple instances.

2) Routed outputs can be cleared (i.e. have no source connected) by clicking on an active switching button whilst holding down the Shift key. To clear all outputs, there’s an item in the system menu.

3) An often requested feature is the ability to rename individual outputs rather than have to use the default formula using the “base name”. From v1.4.1 onwards, individual NDI output names can be edited by clicking on the name to open a small dialog box in which the name can be edited.

In addition, it’s now possible to start the router via a Command Line option, “/force_last“, which will attempt to use the settings in the “last.zri” file, if it exists, and bypass the normal Settings dialog which appears at start-up. This can be used for unattended start-up where the router will be controlled remotely. If alternative config files might be required, the current workaround would be to create multiple folders each with its copies of the Router .exe and NDI .dll and a unique last.zri file, and then use different script/batch files to run whichever one is required.

The “/force_last” option can also be used in a similar way in a Shortcut to bypass the Settings dialog.

NDI D&D Image Viewer

Saving the config/settings for the Image Viewer

A new feature in the Drag-&-Drop Image Viewer in v1.1.x onwards – the current config/settings can be saved and loaded at start-up, using several options in the system menu.
When “Use Last” is enabled, the various settings (eg Resolution, Framerate, Background, Cut/fade, etc) will be saved on exit to the “last.ziv” file. This file will be loaded on start-up, if it exists, and if the “Use Last” setting had been applied, then the saved settings will be applied to the new session. When starting additional instances of the ImageViewer (eg. No 2, No 3, etc), the files are named “last2.ziv”, “last3.ziv”, etc, so that different configs can be loaded and saved for each instance.
When “Use Image” is also enabled, the file path to the currently loaded image will also be saved in the “last.ziv” file, and will be reloaded (after a short delay) if it can be found when the file is reloaded at the start of a new session.

/force_last Command Line

There is also a Command Line option that can be used, “/force_last”, which will attempt to use the settings in the “last.ziv” file, even if the Use Last setting is not enabled in the file (which would normally result in it being ignored). The purpose of this option is to create a way to ensure that a particular configuration is always loaded on start-up, irrespective of how (most of) the settings are changed during the session. To create a suitable “last.ziv” config file, apply the settings you require, but ensure “Use Last” is disabled, and then use the “Save config now” menu option to create a config file which, under normal circumstances, will be ignored, but will be forced to load (and the settings used) by the “/force_last” command line switch. Unless the “Use Last” menu option is re-enabled again, no new file will be saved on exit, so the same config will be loaded each time.

New Layout Modes

The NDI Dual FalseColour Monitor app has a new dialog in v1.0.2.9 for selecting layout modes, and a new mode (the A+A mode above).

Available via the window’s system menu, “Layout Modes” opens a dialog box showing three layout mode options, (a) A+B – 2 inputs, each with single displays, (b) A+A – 1 input with dual displays (horizontally), (c) A+B Quad – 2 inputs, each with dual displays (vertically). The “A+B Quad” mode opens a second row of display windows, so that each of the selected NDI inputs is shown on both rows. However, the display mode of the lower windows is fixed, whereas the upper windows can be switched between normal, false-colour and waveform monitor modes. The lower row can act as a reference when observing the effect of false colour or viewing the waveform monitor above.
