SSEMBLY
The VCM-DAS-3 uses pass-through PC/104 (ISA) connectors so that expansion modules can be
added to the top or bottom of the stack. PC/104 modules must not be positioned between the
CPU board and any PC/104-
Plus
(PCI) modules on the 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 four standoffs to the mounting surface to prevent circuit board
flexing. Standoffs are secured to the top circuit board using four pan head screws. Standoffs and
screws are available as part number VL-HDW-101.
An extractor tool is available (part number VL-HDW-201) to separate the PC/104 modules from
the stack. Use caution when using the extractor tool not to damage any board components.
