  • Flexible transmit schedule definition using either bus lists or transaction tables
  • Available as either multi-function or single function
  • Error injection/detection, triggers, and avionics discretes

Overview

The TechSAT MIL1553-PMC is a powerful MIL-STD-1553B notice 4
compliant interface implemented on a PMC (PCI Mezzanine Card) form
factor module. It implements the 1553 protocol in on-board FPGA logic
thereby off-loading the host significantly. MIL1553-PMC is equipped with
4 dual-redundant 1553 channels and is available in a multi-function version
as well as a single function version.

Features

In addition to the 1553 protocol, MIL1553-PMC also implements comprehensive
test features such as error injection/detection, triggering, and avionics discretes. One trigger IN channel is provided to either start the BC or start a 1553 minor frame time block. One trigger OUT channel is provided to notify of either a receive error, start of BC, or start of a minor frame time block. Furthermore, MIL1553-PMC provides 5 bidirectional avionics discrete GND/OPEN signals.

1553 messages can be defined as either periodic or aperiodic messages,
of which the latter can be prioritized as either high or low priority. High priority messages are processed immediately, whereas low priority messages are transmitted after periodic messages using the remainder of the minor frame time.

To ensure a high-performance data transfer between the hardware and the user application, MIL1553-PMC implements DMA block transfers directly from an on-board FIFO buffer to the user application memory.

Software and Hardware Support

Using dedicated carriers MIL1553-PMC provides integration for PCI, cPCI, PXI, PCIe, and VME platforms. In addition, it provides for a 68 pin SCSI front connector as well as a PMC rear I/O connector.

MIL1553-PMC is shipped with a driver and API library providing the application
programmers with comprehensive means to program the interface card to their specific requirements. Drivers and APIs are available for either Windows, Linux, or VxWorks platforms.
