This page describes the device driver and the device window for Tandberg TT1260 IRD. The actual version of the driver supports the TT1260 with a QPSK demodulator an 1 to 4 inputs. The sat-nms software controls a TT1260 via it's serial (RS232) interface using the Tandberg TT-protocol.
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 .
--- Contains the main receiver settings and status display.
--- Contains the conditional access parameters. See also the remark about RAS and BISS keys below.
--- Contains the parameters concerning the video and audio output.
--- 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 TT1260.
| parameter | description |
|---|---|
| address | The TT1260 communication protocol does not use a device address. leave this field empty. |
| lbandInputs | Select the number of L-band inputs the receiver provides (depending on the model 1, 2 or 4 inputs) |
| 22kHz | Makes the IRD apply a 22 kHz tone to the LNB power for frequency settings above the 'bandEdge' frequency if set to 'AUTO'. With the setting 'OFF' no 22 kHz tone is generated. Changing this value will change the setting for the actually selected input. Whenever the input is switched, the setting defined here is applied to the active input. If you change the frequency, the 22 kHz is applied to the currently active input depending on the new frequency value. You need to switch on the LNB power if you want to use the 22 kHz tone. |
| lnbPower | Selects if the IRD shall apply LNB power to the actually selected input. Changing this value will change the setting for the actually selected input. Whenever the input is switched, the setting defined here is applied to the active input. |
| loFreqHigh | The LO frequency for the high frequency band. The software sets the appropriate LO frequency every time before it changes the receive frequency. |
| loFreqLow | The LO frequency for the low frequency band. The software sets the appropriate LO frequency every time before it changes the receive frequency. |
| bandEdge | The frequency where the software switches the LO frequencies (and the 22 kHz tone if enabled). |
| deviceComment | An optional text entered here appears as an addition to the tooltip which is shown while the mouse is placed over a device icon in the GUI. The "\n" character sequence is translated into a newline character, splitting the text into multiple lines. |
| Serial | Remember to set the line parameters for the serial interface connected to the IRD. The proper setting is 38400,N,8,1 . |
Receiving encrypted programs
Depending on the TT1260 model you own, the IRD is capable to decrypt RAS and/or BISS encoded streams. To make the IRD decrypt these signals properly, please consider the following:
