The page 'Setup' contains the radiometer's installation parameters. Installation parameters are those which are assumed to be changed less frequently than the operational parameters on the Settings page.
The page displays a table with the parameters actually set. Each parameter value is a hyper-link to a separate page which lets you change this parameter. This parameter change page shows the actual parameter setting either in an entry field or in a drop down box. You may change the parameter to the desired value and then click to the 'Submit' button to pass the changed value to the radiometer. The radiometer automatically returns to the setup page when the parameter has been changed. To cancel a parameter modification you already started, either use the 'Back' button of you web browser or click to the 'Setup' button on navigation bar. Both returns to the setup page without changing the parameter you edited.
The table below lists the settings provided by this page.
General
| Parameter Name | Description |
|---|---|
| Note | The radiometer's reading page by default shows the title 'Reading'. By entering a different text here, you can make the radiometer show a customised title. |
| Date / time | By changing this value you can set the internal clock of the radiometer. The clock is set as soon you click to the 'Submit' button in the data entry dialogue. The most precise method to set the time is to enter a time one or two minutes ahead and click to 'Submit' when this time is reached. |
Remark: Even if the radiometer is configured to use NTP to synchronise it's clock, it is important to set the time (the RTC chip) to a reasonable value. Synchronising to a NTP server sets the controllers actual time/date but never sets the RTC chip. When the radiometer starts up, it uses the RTC to initialise it's clock. This time is used until the first NTP synchronisation is done. If the RTC time is too much off, time dependent functions like logging or the sun outage may not work as expected. | | Screen Refresh | The reading page by default refreshes automatically every second. The refresh rate may be slowed down, setting it to zero disables the automatic refresh completely. | | NTP server IP address | To enable the NTP clock synchronisation, enter a valid IP address (aaa.bbb.ccc.ddd notation) of a NTP server accessible to the radiometer. Setting the address to 0.0.0.0 disables NTP time sync. | | Communication address | The serial interface may be operated either with the MOD-95 / Miteq protocol, using a device address 'A' to 'G' or with a simple ASCII / terminal protocol (setting 'NONE'). See chapter 4.3 The RS232 remote control interface for details. | | Rescom emulation port | The port for the Rescom protocol emulation over TCP/IP. To enable the emulation port enter a valid port address. |
Radiometer Front-end
| Parameter Name | Description |
|---|---|
| No. of measurement channels | This defines the type of radiometer front-end connected to the controller: |
1 defined a single channel radiometer 2 defines a dual channel radiometer 3 defines a triple channel radiometer (in fact a dual channel, measuring alternately at 2 frequencies at the second channel. | | Meas. frequency channel 1 | The measurement frequency (GHz) of the first radiometer channel. | | Meas. frequency channel 2 | The measurement frequency (GHz) of the second radiometer channel. | | Meas. frequency channel 3 | The measurement frequency (GHz) of the third radiometer channel. |
Antenna Configuration
The antenna installation parameters are defined in this section. Each parameter appear twice for azimuth and elevation respectively.
Parameter Name --- Description
Position sensor type --- With this parameter you set the type of position sensor the radiometer shall read for this axis. Known sensor types are:SSI-13B (13 bit binary).br SSI-13G (13 bit gray code) SSI-17B (17 bit binary) SSI-17G (17 bit gray code) NONESetting the sensor type to NONE disables any motor control for this axis.
Sense invert --- With this parameter you easily can reverse the sense of a position sensor. The sense should be as follows:
Calibration offset --- The calibration offset is added to the position reading before the angle value is displayed.
Calibration scale --- Normally the radiometer assumes that the full range of a position sensor corresponds 360°. If you are using a multi-turn position sensor or if the position sensor is mounted to the shaft of a gear rather than to the antenna axis directly, the position sensor reading must be scaled. The displayed angle is computed as follows:displayed-value = (raw-reading * scale) + offsetMathematically a scale value of 1.0 disables the scaling. Beside this, the radiometer also accepts the special value 0 to disable scaling at all.
Pointing hysteresis --- If a new target angle is commanded for a particular axis, the radiometer controls the antenna motor until the angle measured with the position sensor matches the target value within this hysteresis.
Upper limit --- The maximum target value accepted at the user interface and via remote control. This software limit prevents the radiometer from running the antenna to the limit position under normal conditions.
Lower limit --- The minimum target value accepted at the user interface and via remote control. This software limit prevents the radiometer from running the antenna to the limit position under normal conditions.
Location
| Parameter Name | Description |
|---|---|
| Antenna latitude | The geodetic latitude of the antenna. For a precise sun outage calculation this value should be entered with 0.001° accuracy. |
| Antenna longitude | The geodetic longitude of the antenna. For a precise sun outage calculation this value should be entered with 0.001° accuracy. |
| Antenna abs. altitude | The absolute altitude over sea of the antenna location. |
Voltage Monitors
Access Control
| Parameter Name | Description |
|---|---|
| User Password | Defines the user password (default 'user'), which is required to change any parameters from the Settings page. An empty password disables the password prompting. |
| Administrator Password | Defines the administrator password (default 'admin'), which is required to change any configuration or calibration settings. An empty password disables the password prompting. |
