9.26 Adtec-EN81

This page describes the device driver and the device window for the Adtec EN81 video encoder family.

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 .

• --- RF / modulator parameters (only present for devices equipped with a modulator unit)
• --- MPEG output parameters
• --- C/A encryption parameters
• --- Video parameters
• --- Audio 1 parameters
• --- Audio 2 parameters
• --- Audio 3 parameters
• --- Audio 4 parameters
• --- The faults page.
• --- The device info page.
• --- The maintenance 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 encoder.

• 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.

The read/write-community strings may be set through the Adtec-EN81 front panel or the web interface of the device. Factory defaults are 'adtec' for the read community, 'none' for the write community. Hence a typical address specification for a Adtec-EN81 may be 10.0.0.1 adtec none .

• readBackDelay --- Defines the delay the driver uses when it reads back parameters recently commanded. The delay is initialized at a proved preset value which should not be changed under normal circumstances.
• withModulator --- If the driver controls a unit equipped with an L-band modulator, you have to set this to 'YES'. This enables the modulator device screen and the parameters in it. Enabling the modulator parameters for a device without modulator will cause a communication fault.
• loFreq --- Sets the upconverter LO frequency. Please note, that this only sets the LO frequency used by the sat-nms software, the value used by the device's web interface has to be set separately. Setting the LO frequency to zero lets the driver show/set the transmit frequency in terms of L-band frequency.
