SSEMBLY
The EBX-18 mounts on four hardware standoffs using the corner mounting holes (A). These
standoffs are secured to the underside of the circuit board using pan head screws.
Four additional standoffs (B) must be used under the circuit board to prevent excessive flexing
when expansion modules are mated and separated. These are secured with four male-female
standoffs (C), threaded from the top side, which also serve as mounting struts for the PC/104
stack.
The entire assembly can sit on a table top or be secured to a base plate. When bolting the unit
down, make sure to secure all eight standoffs (A and B) to the mounting surface to prevent
circuit board flexing.
An extractor tool is available (part number VL-HDW-201) to separate the PC/104 modules from
the stack.
Note:
Standoffs and screws are available as part number VL-HDW-101.
