SSEMBLY
The EPM-CPU-10 consists of two boards which are mounted together with eight 5mm x 15mm
M3 threaded hex male/female standoffs (p/n VL-HDW-101) using the corner mounting holes.
These standoffs are secured to the top circuit board using four pan head screws.
Caution
Extreme care must be taken not to damage components near the corner mounting
holes when tightening standoffs with nut driver tools.
Additional PC/104-Plus or PC/104 cards can be attached to the bottom of the EPM-CPU-10
board set and secured with standoffs or 5mm nuts.
PC/104-Plus expansion modules can be secured directly to the underside of the EPM-CPU-10.
PC/104 expansion modules can be secured to the underside of the EPM-CPU-10, however, the
40-pin and 64-pin ISA feedthrough connectors may need to be extended, and longer standoffs
might need to be used to provide adequate clearance between the PCI connector and the
components on the top side of the PC/104 module.
The entire assembly can sit on a table top or it can be secured to a base plate. When bolting the
unit down, make sure to secure all four standoffs to the mounting surface to prevent circuit board
flexing. Refer to the drawing on page 9 for dimensional details.
An extractor tool is available (part number VL-HDW-201) to separate the modules from the
stack.
