BBG-RADDS
RADDS to OJ194
"SMART" Converter Card
Introduction
|
 |
 |
|
The BBG-RADDS is an ISAbus
compatible card which operates on the ISAbus of any PC or in
a stand alone mode using an external power supply. The BBG-RADDS
interfaces between the RADDS data stream and an OJ194 Radar
console. The onboard processor receives the radar antenna
azimuth and ownship course information from the RADDS data
stream. This information is used to generate the DELTA-X,
DELTA-Y, SIGN of COSINE, SIGN of SINE, RANGE MARKS, and END
OF
SWEEP signals needed to run the radar sweep of the OJ-194
console. The BBG-RADDS is a "SMART" interface due to its
onboard processor.
During power up, the processor reads the configuration
switch and fully configures and controls all functions
required for operation. No ISAbus signals or cpu processing
time is required. DC power is supplied by the ISAbus
requiring no external power supplies. In situations not
requiring a PC interface, the BBG-RADDS operates in a
"STAND-ALONE" mode. With the addition of an external +5 volt
power supply, the onboard processor parses the 10M bps
inputs and generates the OJ194 outputs without the
requirement of a PCbus. RADDS signals and OJ194 signals are
available on coaxial connectors.

Overview
|
The BBG-RADDS is a full-size IBM PC card
which interfaces between the Radar and Data Distribution
System (RADDS) and an OJ194 Radar console. The BBG-RADDS
operates on the ISAbus of any PC or in a stand alone mode
using an external power supply. The RADDS data stream is a
serial radar data network used onboard US Navy ships.
Radar Antenna Azimuth and ownship heading information is
formatted into structured data messages and transmitted over
the RADDS data stream at 10 million bits per second.
The processor, onboard the BBG-RADDS interface, parses the
serial data stream to determine the radar antenna azimuth.
This information is used in a lookup memory table to
generate the DELTA-X, DELTA-Y, SIGN of COSINE, SIGN of SINE,
RANGE MARKS, and END OF SWEEP signals needed to run the
radar sweep of the OJ-194 console.
The BBG-RADDS can, also, be used without
a computer in a stand alone mode. During power up or reset,
an onboard processor reads the configuration switch,
configures the interface card, and provides all signals and
control necessary to receive the RADDS data and generate the
OJ194 signals. |
