PC104 ARINC 429 Interface Card
|
|
|
The PC104/T2/R2 ARINC 429 Interface card
is configured as a 16 bit Stack-through PC/104 interface card and
comprises of two independent transmitter channels that act as Bus
Traffic Simulators and two independent receiver channels that provide
advanced Real Time Monitor and Data Acquisition functions.
|
|

|
General features
The functions on the four channels are available
concurrently at full performance level.
In addition to this the card also
contains, a microprocessor, a time tag register,
Data Acquisition FIFO, and
Dual Port memory for ease of interfacing to the PC AT bus.

PC104 ARINC 429
Transmit Operation
In Simulation mode, the PC104/T2/R2
executes autonomously instructions held in the interface memory and will
perform cyclic and one shot modes of operation. Label repetition rate and
minor and major frame rates are completely controlled at the board level,
which significantly reduces the host PC overhead.
The output rise and fall
time of the output signals are switchable to adapt to the selected transmit
frequency. For each simulated ARINC-429 Transmitter all Labels can be
generated and the label data and descriptors can be updated during simulation
at any time without corrupting the transmission.
Multi-SDI transmissions of
the same label are possible and variation of individual Label/SDI descriptors
in real time are also permitted.
|
Receive Operation
The opto-coupled receivers provide
for comprehensive Bus Monitoring and Data Acquisition.
All received data is
time tagged to 1mS resolution. All Label/SDI filtering is performed on the
card and data captured from the bus is stored in 8k of FIFO memory. The card
can be programmed to generate interrupts when the FIFO reaches the half-full
point or the status of the FIFO's can be polled.

’C’ Source
library
A ‘C’ Source code driver library accompanies
this product. The operation of the PC104/T2/R2 is identical to our PC
ISA PC4/T2/R2 card.
