DDC BUS-6552xxx Series MIL-STD-1553B BC/RT/MT VME/VXI Interface Card

  • Supports All 1553B Dual Redundant Message Formats and Mode Codes
  • 8K x 16 On-Board Dual Access RAM
  • D08(E0), D16 Data Transfers
  • On-Board Time Tag Counter
  • Dynamic Wrap-Around Built-In Test (BIT)
  • On-Board Memory Management


The DDC BUS-6552xxx Series MIL-STD-1553B BC/RT/MT VME/VXI Interface Card provides full, intelligent interfacing between the serial dual redundant MIL-STD-1553B Data Bus and the parallel VMEbus and VXIbus. Software controls the BUS-65522's operation as either a 1553 Bus Controller (BC), Remote Terminal (RT), or Bus Monitor (MT).

The VME/VXI board is packaged on one double eurocard size printed circuit card. Its on-board 8K x 16 dual access RAM is double buffered, preventing partially updated data from being read by the CPU or transmitted to the 1553 Data Bus. The CPU can access any part of the shared RAM as needed.

All MIL-STD-1553 functions: address recognition, Manchester coding validation, bit count and mode code response are provided without subsystem intervention. The BUS-65522 contains eleven VMEbus/VXIbus and 1553 command registers which allow the subsystem to configure its operation under software control.

The BUS-65522 supports four groups of vectored interrupts. One custom interrupt can be programmed by the on-board PROM. The interrupts can be software controlled as to enable/disable, priority level and 8-bit vector.

Additional features include a dynamic wrap-around Built-In-Test (BIT), on-board Time Tag counter, and software loaded board base address and BUS-65522 RT address. The BUS-65522 supports all dual redundant mode codes and message formats. Its full compliance with MIL-STD-1553B makes it an excellent choice for dynamic real time applications.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
