9.439 Narda-Upconverter

This page describes the device driver and the device window for the Narda BUC/LKUX-1 upconverters. The driver has been tested with the L-band to Ku-band version of this upvonverter, but should work with other frequency ranges as well, as the limits of frequency and gain are read from the device.

The driver uses the binary packet protocol over RS485 to communicate with the device.

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 .

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 upconverter.

parameter description
address The device address (decimal 1..15) must match the value set at the device's front panel.
Serial Remember to set the line parameters for the serial interface connected to the up-converter. It is recommended to operate the device at 9600,N,8,1 .
