SubscribeARINC-429 controller with 2 Transmit and 2 Receive Channels
Functional Description
The IIB-429-VME provides 4 ARINC-429 compatible channels (2 receive and 2 transmit) at any rate between 12.5 and 100 kbps.
Because the IIB-429-VME is built upon a flexible platform, user functions can be implemented almost without restriction, making this product flexible and user-friendly.
This VMEbus board has a 3U form factor.
The IIB-429-VME is also available in a 6U form factor (IIB-429-VME-4C) with four times the functionality.
Technical Features
- Flexible platform allows easy addition of user-specific requirements
- Two transmit and two receive channels
- Supports standard (8-bit) and extended labels (10-bit)
- Adjustable data rate from 12.5 to 100kbps
- 16 user selectable labels for interrupt generation upon reception
- Status and statistics monitoring for all channels
- ARINC-429 rise/fall capacitors selectable per channel
- Provides excellent platform for ARINC-429 protocol analysis
Technical Details
Controller:
The onboard MC68332 32-bit CPU executes firmware from local Flash memory, providing a versatile and user-friendly ARINC-429 interface
Receiving Data:
For each receive channel, a local buffer is available for each label. After its parity is checked, the received message is stored in the corresponding label buffer, overwriting the previous content. The last received message for a specific label can be retrieved, by issuing a command from the host to the firmware interface, specifying the channel and label required.
Transmitting Data:
A message is transmitted by passing it as a parameter to the command interface, and initiate the transmit by issuing the appropriate command. Parity generation and checking is done transparently to the user.
Interrupt Facilities:
The user can select up to 16 labels per channel for interrupt generation upon reception of new data. This feature provides a mechanism that allows a user to monitor a label without data-loss.
Statistics:
For each channel and for each label, the numbers of transmitted and received messages are logged into the statistics part of the local firmware. Parity errors are logged globally to a channel.
VMEbus Interface:
The VMEbus slave interface of the IIB-429-VME is compliant with the VMEbus Specification Rev C.1. It supports standard or short addressing (A24/A16), D16/D08 (EO) data transfer capabilities and configurable interrupt level (I(x)).
