SSEMBLY
The EPM-VID-3 uses pass-through PC/104 connectors so that expansion modules can be added
to the top or bottom of the stack, PC/104 (ISA) modules and any PC/104-
Plus
(PCI) modules on
the stack.
The entire assembly can sit on a tabletop or be secured to a base plate. When bolting the unit
down, 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. Refer to the drawing on page 5
for dimensional details.
An extractor tool is available (part number VL-HDW-201) to separate the modules from the
stack.
Arranging the PC/104-
Plus
Stack
1.
Turn the system power off.
2.
Install the EPM-VID-3 module in stack position 0, 1, 2 or 3.
3.
Ensure that jumper V2 matches the chosen stack position (see
Jumper Summary
on page
10).
4.
Additional stack-through modules can be stacked on top of the EPM-VID-3. Up to three
more PC/104-
Plus
modules and/or six regular PC/104 modules can be added.
Warning!
Installing or removing modules from the PC/104-
Plus
stacks while the power is on
may damage the system.
Note
The EPM-VID-3 module is designed to work with PC/104-
Plus
CPU boards. It
does not operate with regular PC/104 stacks (without the PCI connector).
