Abaco Systems / Condor Engineering CONCEI-520 Transition Cable

The Abaco Systems / Condor Engineering CONCEI-520 is a transition cable assembly that bridges the discrete I/O interface of the CEI-520/520A ARINC interface card to external SCSI-3 connectivity. Designed for avionics systems requiring ARINC protocol support, this cable enables seamless integration between PCI-based interface cards and legacy or external test equipment. The RCONSCSI3-6 variant provides a 72-inch twisted-pair cable transitioning from the CEI-520/520A card’s front panel I/O connector (CONM50-D37 or IDC-50 ribbon configuration) to a SCSI-3 connector, facilitating command and data transport across multiple ARINC standards.

Technical Specifications

• Protocol Support: ARINC 429, 419, 561, 571, 573, 575, 582, 717, and CSDB
• Channel Capacity (associated CEI-520/520A): Up to 16 receive and 16 transmit ARINC 429 channels
• Cable Assembly: RCONSCSI3-6, 72 inches long with twisted pairs
• Connector Configuration: Transitions from CONM50-D37 or IDC-50 ribbon connector to SCSI-3
• Power Requirements (associated card): 5V, +12V, −12V (PCI specification mandated); 3.3V generated on-card

– Key Features

• Direct interface between CEI-520/520A discrete I/O and external SCSI-3 systems
• Twisted-pair construction for signal integrity in high-noise environments
• Compatible with ruggedized CEI-520/520A configurations spanning −40 to +85°C operating range
• Supports extended temperature storage to −50 to +100°C
• Meets environmental specifications: up to 95% RH; vibration and shock ratings per ruggedization level

– Typical Applications

• Avionics test and integration platforms
• ARINC 429 bus monitoring and simulation
• PCI-based data acquisition in aerospace ground support equipment
• Legacy system modernization with SCSI-3 I/O interfaces

– Compatibility & Integration

Designed exclusively for the CEI-520 and CEI-520A ARINC interface family. Cable connects directly to the card’s rear Discrete I/O connector. Ruggedization options and environmental resilience of the associated interface card extend to all connected external equipment.
