VME - ARTIC-429 is an ARINC-429 interface board for the VME Bus. Size B (6U). The board features:
• Up to 4 Transmitter ARINC-429 channels
• Up to 4 Receive ARINC-429 channels
• Programmable ARINC parameters
• Data Rate: 100 Kb or 12.5 Kb Word Length
• Parity: Odd or Even SDI: on, 0ff, SDI bits
• Programmable Voltage Amplitude
• 1 Transmit and 1 Receive RS-422 channel
• Programmable transmit /receive loop back mode
• Programmable pre-transmission time delay
NORMAL MODE: The board transmits a data buffer (up to 950 ARINC Words). Upon termination, a Status Flag is set and an optional Interrupt Request is posted.
LABEL MODE: The user specifies for each desired label its data value and a time interval. The board then periodically transmits each specified label at its specified period without interruption of operation. The labels and Periods can be changed without stopping the operation.
In all receiving modes, a user written 256 bit Label Mask is applied to the received data, enabling to pre-filter non-relevant labels. Label-filtering is disabled by filling the mask with 1-s. In addition to the operations described below, each time an ARINC data word is received in any of the receiving modes, o Status Flag is set and an optional Interrupt Request is posted.
NORMAL MODE: The board transmits a data buffer (up to 950 ARINC Words). Upon termination, a Status Flag is set and an optional Interrupt Request is posted
LABEL MODE: Received ARINC data words are stored in a user-specified 256 words long buffer. Each cell in the buffer corresponds to Label value. Each time a data value is received on the Bus, the board stores it in the corresponding cell. Receiving is terminated using the STOP command.
CONTINUOUS MODE: Received ARINC data words are stored in a user-specified buffer (up to 950 ARINC words). When the buffer is full, the buffer “wraps around “acting as a circular buffer. Each time the receive count is a multiple of the
buffer size, a Status Flag is set and an optional Interrupt Request is posted. Receiving is terminated using the STOP command. A Status Flag and an optional Interrupt Request are posted when the Receive Buffer is half-full as well. The board can be set to send an interrupt request when it receives a particular label.
The above receiving and transmitting modes are supplemented by a cluster of Control and Status functions via which the user can specify additional conditions and modes of operation and receive from the board Status and Data such as Receive Count, Channel Status, System ID, Last Received Label and more.
