Swift™ PC/104-Plus NTDS Serial Type D and E

A high-performance serial NTDS interface for PC/104 embedded computers

Powerful NTDS I/O capabilities in a stackable package

• Industry Standard PC/104-Plus Module
• Full Duplex NTDS channel
• Passive Tap Capability
• Test Without Disconnecting Cables

The Swift PC/104-Plus NTDS Serial card connects embedded computers to military computers and peripherals with MIL-STD-1397C Type D or E interfaces. The Swift PC/104-Plus provides reliable serial NTDS communications in the specialized or extreme embedded computing environments where this architecture is used. Unlike other computer architectures, the PC/104 form factor has no backplane, and instead modules are stacked together like building blocks. Multiple modules are fastened together with standoffs, resulting in a very rugged assembly. Sabtech's Swift conforms to the commercial PC/104-Plus specification, providing full support for the PCI bus and electrical pass-through for the ISA bus.

Sabtech's Swift is easy to program and offers a variety of input and output modes to support any NTDS protocol. Hardware-independent input and output channels allow the Swift to perform simultaneous input and output (full duplex) operations.

Swift boards can be used for passive tap applications as well as normal NTDS I/O. An on-board time stamp generator tags individual input words with 125 ns resolution. Time stamping is software-selectable and can be used with active or passive communications.

All boards in the Swift family are software-compatible, making it easy to mix parallel and serial NTDS boards in the same system as well as allowing transparent migration of applications between PCI, PMC, cPCI, PCIe, and PC/104-Plus versions of the Swift. Device driver software is available for the most commonly-used operating systems.

For maintenance and reliability, Swift NTDS Serial boards have an internal loopback path that allows it to be tested without disconnecting cables. Swift Serial Type E boards fully implement all the System Integrity Features (SIF) specified in MIL-STD-1397C. The Swift can be updated in the field by reconfiguring its Field Programmable Gate Array (FPGA) logic to add features or compensate for non-compliant interfaces. Using FPGA technology reduces component obsolescence, enabling the Swift to be deployed and supported for years to come.
