VISTALINK™ REMOTE MONITORING/CONTROL
8.1.
WHAT IS VISTALINK™?
VistaLINK™ is Evertz's remote monitoring and control capability over an Ethernet network using Simple
Network Management Protocol (SNMP). SNMP is a standard computer network protocol that enables
different devices sharing the same network to communicate with each other. For monitoring there needs
to be a detecting device that automatically reports all errors to a central alarm and error logging station.
We also need to be able to interrogate individual detector devices from the central station to determine the
status of individual channels. Finally, we need to be able to configure devices in the network from the
central station and receive feedback that the configuration has been carried out.
There are 3 components of SNMP:
1. An SNMP manager also known as a Network Management System (NMS) is a computer running
special software that communicates with the devices in the network. Evertz VistaLINK™ Pro Manager
graphical user interface (GUI), third party or custom manager software may be used to monitor and
control Evertz VistaLINK™ enabled products.
2. Managed devices (such as 7712HDC), each with a unique address (OID), communicate with the NMS
through an SNMP Agent.
7700FR-C MultiFrame and communicate with the manager via the 7700FC VistaLINK™ frame
controller module, which serves as the Agent.
3. A virtual database known as the Management Information Base (MIB) lists all the variables being
monitored and which both the Manager and Agent understand. Please contact Evertz for further
information about obtaining a copy of the MIB for interfacing to a third party Manager/NMS.
For more information on connecting and configuring the VistaLINK™ network, see the 7700FC Frame
Controller chapter.
