| Vee signal enabled | Pins 2 & 3 closed | |
| Backlight signal disabled | Open | |
| Note: W1 has a dual use pin. If 24-bit PC-video is used, the dual pin becomes an input rather than a flatpanel signal selector. In this case, the jumper should be removed or set to pins 2 & 3. | ||
MISCELLANEOUS TECHNICAL NOTES |
The MiniModule/VFP-II can be installed as part of an Ampro CoreModule stack, Ampro Little Board CPU, or PC/104-compatible module. Analog monitors with a 15-pin or 9-pin interface can be attached to the CRT (J3) connector with an adapter (10-wire flat ribbon cable to a DB9S D-Sub or DB15S D-Sub connector). Blurred video may occur if ribbon cable used with the CRT (J3) connector is non shielded and longer than 24 inches. The flat panel connector does not share a standardized interface pin configuration and therefor may not be readily compatible with other devices. |
