Some Deltacast cards allow for reconfiguration by loading a different FPGA, enabling various input/output setups depending on the model.

12G Models (Used with Current M|8 and M|4 Bundles)

• 4C (Dynamic bidirectional): This is the most flexible option. You’ll see 8 inputs and 8 outputs, but each connector can only be used for one direction at a time. For example, if connector 1 is set to input, it cannot be used for output.
• 40 (8 fixed inputs/0 outputs): Only 8 inputs will be visible; no outputs are available.
• 04 (0 fixed inputs/8 outputs): Only 8 outputs will be visible; no inputs are available.

Although labeled as 4C, 40, or 04, you will see 8 I/O ports because this is based on the number of 12G connectors. Be sure to review the connector mapping and any port limitations.

Make sure to also check the connector mapping and limitations of the ports.

Older 3G Models (Used in Previous Systems)

• 8C (Dynamic bidirectional): Previously used with 3G models, but has known TX (transmit) performance issues.
• 8B (Bidirectional): Used in later 3G deployments before switching to 12G. It resolves TX issues but does not support color space converters.
• 80 (8 fixed inputs/0 outputs): Eight dedicated input channels.
• 84 (4 bidirectional channels + 4 fixed inputs): Four channels are fixed as inputs; the remaining four are bidirectional.

Reconfiguration Process

With Drivers 6.16 or later

First make sure that drivers are installed, then:

• Open the Terminal application.
• Run the following command:

sudo '/Library/Application Support/Deltacast/FWUpdater/FWUpdater.app/Contents/MacOS/FWUpdater' -d -c

• This will list connected Deltacast devices and their configurable options:
• To apply a new configuration, use:

sudo '/Library/Application Support/Deltacast/FWUpdater/FWUpdater.app/Contents/MacOS/FWUpdater' --id=1 --config=3

• Replace --id=1 with the correct device ID if you have multiple cards.
• Replace --config=3 with the desired configuration code (e.g., 3 for 12G-4C).

• You should see a firmware reflash status, and when completed it should look like this:
• Restart the Mac.

That's it, your card should be reconfigured with the appropriate configuration.

Tip: You can view additional options by running the FWUpdater with the help command to explore all possible actions. Check the list of possible commands:

With Drivers 6.15 or earlier

Once the driver is installed,

• start the application "Terminal"
• Drag and drop the application "DELTA_Configurator" on the Terminal window
• Then type " 0 8B" (the 0 is the index of the board, and 8B the configuration you want, if you have multiple boards connected you may have to change the index)
• It should look like this:

• And then carriage return.
• It should then show this:

• Wait for it to be finished, and then restart the computer.
