The Pointing-Lock logical device checks the lock state of up to twenty IRD-Chain devices and controls the enable state of one Antenna-Pointing device.
The function of the Pointing-Lock device is to disable the antenna operation if at least one of the configured IRD-Chains has selected this antenna AND is set to 'locked' state. This prevents the operator from moving the antenna while it is used to receive a program. The chains may be represented by IRD-Chain or RX-Channel-Select-CDB devices.
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 device info page.
--- The maintenance page. The configuration parameters from this page are described below.Configuration parameters
At the maintenance page of the device window there are a couple of configuration parameters which must be set to interconnect the Pointing-Lock device with the antenna controller and the IRD-Chain devices.
| parameter | description |
|---|---|
| pointingDevice | The name of the Antenna-Pointing device which controls the antenna of interest. The Pointing-Lock disabled this device by setting it's mode to OUT-OF-SERVICE. For this reason you may not use a Antenna-Tracking device to control the antenna, the device would suspend tracking while it is disabled. pointingDevice may be left empty if no Antenna-Pointing device shall be controlled (the LOCK state ist still signalled via the 'locked' state variable of the Pointing-Lock device. |
| antennaName | The name of the antenna as it appears in the configuration file / drop-down box of the IRD-Chain devices. Note that all IRD-Chain devices must use the same name for a particular antenna to let the Pointing-Lock device work properly. |
| irdChainDevice.?? | These parameters define the names of the IRD-Chain or RX-Channel-SElect-CDB devices the Pointing-Lock shall monitor. The parameters may be assigned in arbitrary order, empty / unused entries are skipped by the device. |
