SSEMBLY
The VL-EPM-P2 uses both PC/104-
Plus
(PCI + ISA) connectors, and the VL-EPMp-P2 uses
only the PCI connector. The module can be installed in PCI stack position 0-3. As shipped, the
VL-EPM-P2 is configured for position 0 (first on the stack adjacent to the CPU board). Make
sure that jumper V2 matches the chosen stack position (see Jumper Summary). PC/104 (ISA)
modules must not be positioned between the VL-EPM-P2 and any PC/104-
Plus
(PCI + ISA)
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-105 (metric thread) or VL-HDW-106 (English
thread).
An extractor tool is available (part number VL-HDW-201) to separate modules from the stack.
Use caution when using the extractor tool not to damage any board components.

Plus
stack. The module can be installed in slots 0-3. Jumper block V2 must be configured to match the
module's stack position.
