The NMOS Quick Connect utility

ip streamsThe NMOS Quick Connect utility is an in house application that we have developed to help solve NMOS connectivity issues in the field. It will be included in Drastic version 8 software that is able to access cloud streams and devices. 

NMOS Quick Connect is a simple Windows application designed to see all available NMOS flows and connect one device to another. We developed it to avoid using the NMOS registry or other trappings, so that our tools can directly connect devices that may have issues with specific NMOS controller providers.

The other reason we made this was to allow multi network access. Some devices do not support a separate control network. When the NMOS Quick Connect utility is on a machine that has access to both (or all) networks, it will pick up the NMOS from all of them. This does mean you will see two devices if they support NMOS on control and video NICs (or more if they support ipv6), but it also means it can connect single/video-only NMOS devices to control only NMOS devices. That is something we have not been able to get our NMOS orchestrators to do.

It uses an internal mDNS/Bonjour to seek out all the NMOS devices directly, and then as it finds them, it adds senders to the top drop down, and receivers to the bottom:

NmosConnect

When one is selected, if we detect all the NMOS protocols we need, we light up its indicator green. Clicking the "Connect (Tx->Rx)" button will cause it to find any outgoing flows on the transmitter, and attempt to connect them to the receiver. If the video does not connect, then you will get an error message dialog. Otherwise, it will detect audio and anc flows in the transmitter and attempt to set them into the receiver. There is also a "Disconnect Rx" to clear the receiver.

We have to wait for calls from the devices as we are not using the registry. You may need to leave it running for a while, until all the devices have refreshed their mDNS.

Currently the NMOS Quick Connect utility is included in installs of DrasticScope, videoQC, FlowCaster, and Net-X-Code Server. It is also available as a standalone app, and it will run for free, but with ads, like below:
