GE Fanuc Intelligent Platforms has introduced three RoHS-compliant ExpressCard interfaces for testing critical aircraft systems. The R15-EC is a dual-port MIL-STD-1553 ExpressCard interface; the RAF-EC is a dual-port ARINC 664 ExpressCard interface; and the RAR-EC is a multichannel ARINC 429 ExpressCard interface.

Leveraging the higher bus speeds that are especially important in the commercial avionics market utilizing AFDX/ARINC 664, these interfaces enable bus traffic capture through the high performance ExpressCard technology. The three ExpressCard interfaces are available in a range of configurations, including card only, card and appropriate analyzer, and a full turnkey portable analyzer system that includes the interface card, protocol analyzer and semi-rugged laptop.

The R15-EC MIL-STD-1553 ExpressCard interface provides one or two 1553 channels integrated with API software that provides instant access to all 1553 databus functionality. Standard features include IRIG-B receiver (AM or DC/TTL), generator (DC/TTL), real-time bus playback (with ability to edit out RTs), a periodic message insertion, error injection/detection, conditional BC branching, 45bit timetags and "Oneshot" BC operation. The bus monitor mode provides 100 percent bus monitoring of a fully loaded 1553 bus.

The RAF-EC ARINC 664 ExpressCard is a high-performance interface for monitoring, generating and analyzing full-bandwidth AFDX-ARINC 664 protocol traffic. GE Fanuc's exclusive pipeline architecture maximizes packet throughput using parallel controllers and efficient DMA transfers, thereby avoiding the bottlenecks of CPU-based interface solutions, GE Fanuc said. Configurable as either one dual-redundant AFDX/ARINC 664 interface or two independent ports, users have complete access to all frame and header data. Each incoming packet is tagged with a 20ns resolution, 64bit time-tag. An IRIG-B receiver/generator is included for synchronization to external IRIG-B time sources and for synchronizing multiple CNIC boards. In addition, I/O triggers, error detection/injection, BIT and link/protocol statistics are provided.

The RAR-EC is an intelligent, high-density, ExpressCard interface that provides up to seven receive and four transmit fully independent ARINC 429 channels, along with up to four bidirectional avionics level I/O discretes. Features include programmable data rates and parity, error detection, multiple buffering modes, timetagging and automatic transmit slew rate adjustment. Configuration options include selection of channel count, a mix of ARINC 429 and ARINC 573/717, and a Dataloader configuration.

Pricing ranges from $2,300 to $9,900, depending on function (single/multi), channel count and options.
