Calrec Hydra2 I/O boxes are simple to set up and use. The only configuration requirement is that each I/O box must have a unique ID on the Hydra2 network to which it is connected. This ID is an integer in the range of 1-255, and is set in binary using DIP switches on each box.

This App makes it simple to convert from a decimal ID to a binary representation, telling you specifically which switches to turn on.

Alternatively, you may want to go from binary, back to a decimal ID if you have a box already configured with an ID. With this App, you can easily find the decimal ID before you connect it to a network.
