Ping test is useful for checking if one or more remote systems are reachable from a server. Up to 4
systems can be registered as the targets of a Ping test, which makes it possible to identify the hop
(segment of network) where network failure may happen. For example, local router, remote router and
remote Encoder can be pinged from a Decoder simultaneously.

Network test
Network Test dialog is invoked by selecting Network Test on the Tools menu.
Network test can be used for measuring effective bandwidth and/or packet loss rates between a
server and a PC running the ENVI VMS by generating test traffic of constant bitrate. This feature is
useful for identifying the reason why video quality comes poorer than expected. TCP protocol can be
selected for measuring effective bandwidth, while UDP protocol is appropriate for checking if the
network is not reliable.

System test
Selecting System Test on the Tools menu invokes a dialog box on which system H/W status,
video/audio output function and serial ports can be diagnosed.
