Do you need a compact cost effective solution to your PMC mounting issues? Why use a complete cPCI, VME, VPX or other standard chassis for your project when all you need is a backplane and power supply for most embedded applications. PMC-MC-X2-RIO and PMC-MC-X4-RIO [PCI Mezzanine Card Mini Carrier with 2 or 4 positions and Rear IO] have been designed to create a compact configuration with built in power supply and slot 0 functions - bus arbitration, reset, clock, interrupt routing, terminations, Fan speed control, over temperature [X4 only] protection, reverse power protection [input side]. Select your favorite CPU and add PMC card(s) for a complete system.

If the X2 or X4 are close and not quite what you are looking for; you could design your own chassis, or collaborate with us to make a custom chassis and motherboard for you. Our designs are captured in SolidWorks. We can make changes and supply STEP or other format files for you to use in your design process. For example, if you need a mix of XMC and PMC cards we could add a switch or Bridge to the motherboard and change to an XMC interface for slot 0. Similarly we can add IP Module positions by adding an FPGA to the motherboard. An easy one would be to make a x6 or x8 version with PCI bridges or XMC switches for expansion. With the X2 and X4 designs fully functional it is relatively easy to morph into a custom solution for your requirements.

PMC-MC-X2-RIO-Chassis is designed to work with PMC-MC-X2-RIO a two PMC position mini carrier. PMC-MC-X4-RIO-Chassis is designed to work with PMC-MC-X4-RIO mini carrier with 4 PMC positions. The chassis when combined with the X2 or X4 create an easy to use PMC stack with built in power supply, fans, slot 0 functions and mechanical enclosure.

The PMCs are stacked in parallel. The X2 has one PMC mounted top and one bottom to make a three high sandwich with the basic PMC dimensions for the X, Y and a double high stack for the Z dimension. The X2 is slightly wider to allow for a power switch in the front, power entry at the rear, and some headers on the side. Similarly the X4 has two positions on the top and two on the bottom. The chassis are designed to have minimal clearance all around the X2 and X4 and minimal height to keep the design compact. We even recessed the PC board in two locations to allow the fans to be mounted internal to the chassis without adding much to the overall width of the chassis.

Use the supplied 10 mm stand-offs to retain the PMC boards to the X2 or X4. The supplied stand-offs are male/female to allow the stand-offs to be connected through the X2 or X4 then attached with standard screws to the PMC. The PMCs are back-to-back and share common mounting holes for the bezel and stand-offs. Once the cards are attached mount them to the bottom of the chassis with the included stand-offs(6). Slip the top cover over the assembly from the front rotating slightly to engage the side and front retaining panels. 6 screws secures the top/front assembly. Add the rear plate with 4 screws and you are complete. The chassis can act as a stand-alone box on a bench or similar - rubber feet included. Alternatively the captured fasteners on the bottom surface can be used to mount to a plate for rack mount or internal to a secondary chassis etc.

Plug in the supplied wall mount transformer power supply to the rear PowerDin4 connector.

Turn the power switch at the front of the chassis to the "on" position. Assuming you have a PrPMC in position 0; it will "boot" and start operation. Power supply status is shown on the rear of the chassis.

The chassis is Black Anodized Aluminum with white silk-screen.

Cooling is taken care of with two fans mounted to the side wall of the chassis. The air will travel across the PMCs and out the exhaust ports on the opposite side of the chassis. The 10 CFM fans are monitored via temperature on the motherboard surface and controlled to minimize fan speed while keeping the temperature down. The speed control can be bypassed if your project requires.
