ARINC 429 PC/104 Interface

  • PC/104 compliant
  • Six ARINC 429 channels (4R/2T)
  • Twelve configurable discretes
  • Commercial, industrial or military temperature
  • Transient voltage protection
  • Custom versions available
  • The PM429-1 is a low-cost ARINC 429 interface for PC/104 embedded computers. In addition to the four receive and two transmit ARINC 429 channels, the PM429-1 has configurable input (8) and output (4) discretes and a programmable timer. All ARINC 429 channels have independent speed control and a large, 32-label FIFO buffer. Each receive channel has a programmable 16-label filter. The straightforward architecture and IO-mapped registers make application programming a simple task in any operating system. Either polling or interrupts may be used.

    Designed for flexibility, the PM429-1 can be ordered in various configurations to provide the most cost-effective solution for a given application. Commercial, industrial, and military temperature grades (-55° to +85° C) are available. Each input discrete may be wired for 5, 12, or 28 V DC in a series or shunt configuration. Each output discrete is open-collector with an optional internal pull-up resistor. The number of discretes and ARINC 429 channels can be reduced for cost savings. For critical applications, the PM429-1 can be ordered with the transmitters permanently disabled.
