Blackmagicdesign Videohub Installation And Operation Manual page 917

This example is for the Smart Videohub which is a 16x16 router.
If the Videohub Server has no device connected, the block will simply be:
VIDEOHUB DEVICE: ↵
Device present: false ↵
↵
If a device is present, but has an incompatible firmware, the status
reported will be:
VIDEOHUB DEVICE: ↵
Device present: needs _ update ↵
↵
In the last two situations, no further information will be sent, unless the situation is rectified.
If the Videohub Server detects a new Videohub attached, it will resend all blocks except the
protocol preamble to indicate the device has changed, and allow the client to update its cache
of server state.
Initial Status Dump
The next four blocks enumerate the labels assigned to the input, output, monitoring and
serial ports.
Videohubs that do not have monitoring or serial ports do not send the corresponding blocks.
