Page 6: Introduction
Introduction Description The VL-EPM-V7 expansion module provides VGA and LVDS display outputs for PC/104-Plus embedded systems. A Mini PCIe expansion socket accommodates plug-in modules such as A/D convertors, Ethernet, Wi-Fi modems, MIL-STD-1553, and other devices. With a full industrial temperature rating and rugged construction, the VL-EPM- V7 is an ideal solution for embedded video applications in harsh, mobile, and remote environments. -

Page 11: Hardware Assembly
ARDWARE SSEMBLY The VL-EPM-V7 uses both PC/104-Plus (PCI + ISA) connectors. The module can be installed in PCI stack position 0-3. As shipped, the VL-EPM-7 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, page 11). -
Page 12: Stack Arrangement Example
RRANGEMENT XAMPLE Figure 5 shows the VL-EPM-V7 installed above the CPU board in the PC/104-Plus stack. The module can be installed in slots 0-3. Jumper block V2 must be configured to match the module's stack position. Refer to the section titled Jumper Summary on page 11 for more information. -

Page 24: Appendix B - Technical Notes
In cases where an on-board graphics controller is to be used at the same time as the VL-EPM-V7, it is typically necessary to configure the BIOS of the CPU board so that it recognizes the on-board controller as the primary graphics device. This is because when the CPU board detects the presence of an add-on graphics controller, the on-board controller is usually not fully initialized.
