VNM 250 System Controller
All Matrix systems require one device that acts as the system controller. For small systems
(ten devices or fewer), this can be either a VNE 250 or VND 250. For larger systems, a
VN‑Matrix Enterprise Controller must be used.
Systems Controlled by
VNM Enterprise Controller
Systems Controlled by
VNM 250 Device
The VNM Enterprise Controller is able to
control all VN‑Matrix systems (large and small)
but is required for large systems (more than
10 devices). A VNM 250 device can control small systems
(10 devices or fewer). It is less effective as the
system size increases.
The system is controlled through a powerful
web‑based user interface served from the
Enterprise Controller. The system is controlled through a more
limited web‑based user interface served from
the VNM 250 controller device.
Supports all VN‑Matrix devices, including
recorders. Supports VNM 250 encoders and decoders
and PCs running the VNS 104 software
decoder. Does not support recorders.
NOTES:
• A small system that includes a VNM 250 device must be controlled by either a
VNM Enterprise Controller or a VNM 250 device.
• If an incompatible VN‑Matrix device is added to a small system controlled by a
VNM 250 device, the controller is unable to detect or control that device.
Transport Protocols Used for Streaming
The source data from a VN‑Matrix encoder can be distributed to multiple displays/decoders
(one‑to‑many) or to a single display/decoder (point‑to‑point). A previously recorded stream
can be distributed in the same way and may be thought of as an encoder in this context.
A stream may be transported from the source (encoder, recorded stream) to the display
(decoder) using one of three methods:
