Argus Radar - RADAR CONFIGURATION

3.8.1 Transceiver Communication Type
Pressing the A button of fig. 3.8.1, page 3.12, the following list will open:
The list permits the selection of the communication’s type used to control the transceiver.
Other Comm: For any transceiver that cannot be controlled by the console, but is still able
to generate the appropriate video, trigger and antenna synchronism signal.
Serial Comm: For the standard connection with RS232 serial line.
SXI n Comm: For video combined connections, all the signals needed are combined with
the video on only one coaxial cable; "n" is the console priority for that transceiver.
Higher numbers have higher master priority than lower ones.
CAUTION
PRIORITY NUMBERS ARE IMPORTANT AND SHOULD NOT BE MIXED
UP. IF THE SETUP HAS TO BE TRANSFERRED FROM CONSOLE TO
CONSOLE VIA A MEMORY STICK, CHECK THAT PRIORITY IS NOT
THE SAME IN ANY OF THE CONSOLES CONNECTED TO THE SAME
RADAR INPUT. TWO CONSOLES WITH SAME PRIORITY, TRYING TO
BE MASTER OF THE SAME TRANSCEIVER WILL SEND
CONFLICTING COMMANDS AND MAKE IT JUMP BY DIFFERENT
PRFS OR TUNING SETTINGS.
3.8.2 Transceiver Communication Type
Pressing the B button of fig. 3.8.1, page 3.12, (password protected), it is possible to
adjust amplitude and slope of the TXRX Pre-STC. The range scale is automatically set to
0.75 NM. Amplitude and slope can be adjusted using the up and down arrow. This
adjustment optimises the minimum visible distance and it can affect the auto-tuning
performance for TXRX not derived from SRT.
Connecting the probe of the oscilloscope to the pin STC of TB13 of the RTM Control B
PCB (the connector of the I.F. Amplifier, normally the blue wire), the PRESTC ramp will
be shown on the scope.
The Amplitude shall be adjusted to be about 4 - 4.2V.
The Slope shall be adjusted to be about 2 - 3 µs.
