1.444 Nevion-TVG425

This page describes the device driver and the device window for the Nevion TVG-425 transport stream gateway.

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 .

• --- Stream overview
• --- Stream 1 settings and state
• --- Stream 2 settings and state
• --- Stream 3 settings and state
• --- Stream 4 settings and state
• --- Stream 5 settings and state
• --- Stream 6 settings and state
• --- Stream 7 settings and state
• --- Stream 8 settings and state
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device.

• parameter --- description

• address --- The SNMP address specification for the device. The full address specification consists of the following fields:aaa.bbb.ccc.ddd:pppp read-community write-community

  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.

• readBackDelay --- Delays the read back of a parameter actually set for at least the given delay time. This shall ensure that the device has processed the new parameter before it is read back. You should leave this parameter at it's default setting.

Remarks

• The driver does not permit to change the device's stream configuration, i.e. which ASI or IP inputs/outputs belong to which stream. It however reads this configuration from device every 5 seconds and assigns the ports to streams according to the configuration read.
• The driver addresses the ASI / IP inputs and outputs by stream, not by the physical port number. This in particular means that e.g. the asiin.03.* variables refer to the ASI port actually defined as input for stream 3, not to the physical port number 3. You may read the variable asiin.03.port in this case to evaluate the number of the physical port the stream uses.
