9.449 Newtec-EL470

This page describes the device driver and the device window for the Newtec EL470 DVB-S2 Modem. The driver is not a full implementation of all parameters provided by the modem, it only contains a number of parameters required for operational use of the modem. The driver controls the modem via SNMP.

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 .

• --- The IF parameters (frequency, level, etc.) and some global settings.
• --- The modulator settings.
• --- The demodulator settings.
• --- 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 Newtec EL470.

• 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.

• tx.loFreq --- The LO frequency to be used with the L-band output of the device. Entering the LO frequency of the BUC here (MHz), permits to display/set the transmit frequency in terms of true RF frequency. Setting this parameter to 0 lets the software display the TX frequency setting as the L-band frequency.

• rx.loFreq1 --- The LO frequency to be used with the L-band input 1 of the device. Entering the LO frequency of the LNB here (MHz), permits to display/set the receive frequency in terms of true RF frequency. Setting this parameter to 0 lets the software display the RX frequency setting as the L-band frequency.

• rx.loFreq2 --- Like rx.loFreq1, but for the L-band input 2 of the device.

• 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.
