Elma Bustronic Corporation, a California-based provider of high-performance backplanes, recently announced that it has started offering wide range of Rear Transition Modules (RTMs) in both custom architectures as well as standard architectures such as VPX, VME/64x, VME, CompactPCI (News - Alert) and ATCA.
Officials at Bustronic said in a release that these latest RTMs are designed for various standardized or custom systems in military/aerospace, medical, industrial, communications, and energy markets.
The rear transition modules (RTMs) are electronic units that bring IO (input/output) signals out the rear side of the backplane. A backplane is a printed circuit board that connects several connectors in parallel to each other in such a way that each pin of each connector is linked to the same relative pin of all the other connectors forming a computer bus.
The latest RTMs offered by Bustronic provides higher resistance to shock and vibration as compared to a ribbon cable connection style, when directly plugged into the backplane, says company.
Depending on the architecture, the latest RTMS are available in 3U x 80 mm, 6U x 80mm, 8U x 80mm sizes.
Bustronic said that these latest modules can come with or without injector/ejector handles. The injector/ejector handles help the board lock securely into place. Unique rear I/O and RTM solutions for VXS and VPX are the latest offerings that includes universal VPX RTM breakout board and VMEbus versions that are compatible with Motorola (News - Alert) SBCs (single board computers).
The UNIVERSAL VPX RTM breakout board facilitates a test engineer to access I/O signals on custom built VPX boards. This RTM breakout board is specifically used to bring out single ended TTL signals, which might be part of a customer’s custom IO board. It is not intended for high-speed signals.
Available in 6U x 160 mm RTM format, this UNIVERSAL VPX RTM breakout board has a 10 layer design. Strain relief holes are provided directly behind the front panel mounting location for clamping bar or wire-ties. The breakout for all signals is possible depending upon connector configuration. Typical configuration has connectors installed to bring out J0, J2, J3 and J4 signals, says company.
The VMEBUS RTMS mainly plugs into a VME backplane for more robust connectivity. Direct plugging offers higher resistance to shock and vibration as compared to the standard P2 / ribbon cable connection style, says company.
Available in single slot 6U x 80mm form factor, the VMEBUS RTMS are compatible with Motorola SBCs and includes geographical addressing. One EIA-574 (DB9M) is provided, which is the 9 pin RS232 standard. EIA-574/RS422 is also provided. The module has 1101.10/11 style handles and gasketing as well.
In addition, Bustronic offers contract assembly and design services for various boards, form factor extenders, adapters, system monitors, and more.
