9.229 Envivio-4View-D1

This page describes the device driver and the device window for the Envivio 4View D1 MPEG-4 video decoder.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

--- Decoder settings
--- Decoder readings
--- The faults page.
--- The device info page.
--- The maintenance page.

Configuration parameters

The only configuration parameter which must be set for the Envivio decoder is it's IP address:

parameter	description
address	Enter the IP address of the decoder here followed by a blanc character and the SNMP community string set at the decoder. Example:
10.0.0.1 private

Remarks

To change parameters at the device, the decoder must be in stopped mode. The changes will be applied when the decoder is started again.
Loading and saving presets for this device is only possible if the device is in STOPPED mode.
The decoder does not provide a true summary fault indication. The driver reads the 'lastFault' parameter from the device and displays this at both device window pages. The '4VIEW' fault flag is set by the driver while the 'lastFault' message is not empty. This leads to a latching behaviour for some faults: If e.g. you mistyped the input URL, the driver states this fault until the decoder properly decodes another signal. This is exactly how the web user interface of the device behaves.
