SR429/1
FEATURES
  • The SR429/1 can be pre-configured to any specific ARINC label, or can be ordered as a universal converter that the integrator may set prior to installation
  •  SR429/1 delivers each of the 23 data bits on its own dedicated output pin, providing the utmost in design and specification flexibility
  • Available as Pre-Configured or as a settable, Universal Unit
  • Meets RTCA DO-160 and military test standards
  • No software, firmware or programmable logic
  • Can be specified for any single-bit on any single label
  • Other options include ARINC transmission speeds, parity checking, and discrete output type (Active Low or Active Open)
  • Internal watchdog timer to monitor validity of incoming ARINC data stream  
  • Accommodates two additional external signal inputs with discrete output on “fail” 
  • The SR429/1 uses a filtered DC-37P connector to provide 330 pF capacitive coupling per pin to chassis ground for enhanced EMC capability
  • Reduces circuit complexity, size, weight, and installation labor
  • The SR429/1 accommodates a single valid ARINC label (000 – 377)
  • The specified label can be factory preset, or set by the user when ordering a Universal unit
  • SR429/1 is a compliant ARINC 429 receiver that may be ordered as a high speed (100 kbps) or low speed (12.5 kbps) unit
  • Universal units can be set to either speed
  • ARINC 429 bits 9 through 31 are latched as unique outputs on dedicated connector pins 9 - 31
  • Each output contains the most recent data received for the selected label
  • Data is held until a new word containing the selected label is received
  • Includes a Master Reset (/MR) input (Pin 36) that resets back to its power up state and holds the unit in reset as long as the master reset line is held low
