This unit
The Curtiss-Wright DHAS-MBS1616 is a 16×16 crosspoint switch designed for MIL-STD-1553 avionics bus environments. It functions as a virtual patch panel within a compact 1U rack-mountable chassis, enabling dynamic routing between 16 transformer-coupled LRU ports and 16 MIL-STD-1553 differential buses without physical rewiring. The switch supports MIL-STD-1553A, MIL-STD-1553B, and mixed-device environments, accommodating LRU units configured as bus controllers (BC), remote terminals (RT), or bus monitors (BM).
Technical Specifications
Configuration: 16×16 crosspoint switch
Chassis: 19" rack-mountable, 1U height
LRU Ports: Up to 16 transformer-coupled inputs via standard concentric twinax connectors
Bus Connections: Up to 16 MIL-STD-1553 differential bus outputs via standard concentric twinax connectors
Control Interface: EIA-232 (RS-232) out-of-band port
Supported Standards: MIL-STD-1553A, MIL-STD-1553B, mixed-device operation
NSN: 5998-01-608-8068
Key Features
Single-path switching - each LRU port connects to one bus at a time
Relay-based physical disconnection of idle LRU and bus coupling elements
Non-volatile configuration memory with automatic restoration to last working state after power-up
Command-line interface (CLI) with on-line help and scripting support (PERL, TCL)
Transformer-coupled LRU support only; direct-coupled devices not compatible
Supports both non-redundant and redundant (dual or greater) device configurations
Typical Applications Avionics test systems, MIL-STD-1553 bus simulation environments, LRU functional validation, multidevice integration testing, and aerospace defense system development.
Compatibility & Integration Designed for transformer-coupled MIL-STD-1553 devices. External power supply required. Integrates into larger test infrastructure via RS-232 control port and supports automated test sequences through CLI scripting.
Curtiss-Wright DHAS-MBS1616 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Curtiss-Wright DHAS-MBS1616. Calibration covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Curtiss-Wright DHAS-MBS1616 faults: power supply failure (cRIO-9073/9074), C-series slot connector wear, PXI chassis fan failure, GPIB interface failure on VXI controllers, BIOS/EEPROM corruption. NI CompactRIO most common faults are power supply failure on older cRIO-9073/9074 chassis and C-series module slot connector wear from repeated hot-swap cycles. PXI chassis fan failure is the most common wear item — chassis fans are field-replaceable. VXI embedded controllers most commonly develop EEPROM corruption and GPIB interface failure.
