DIMM-PC/MD Product Manual Introduction 2. INTRODUCTION Kontron DIMM-PC-Concept It is likely that anyone who deals with micro-controller-development, has already thought of the application of PC-architecture and considered the PC as the engine for an application. However, most design engineers will get back to the old 87C51 or a similarly more or less efficient micro-controller.

DIMM-PC/MD Product Manual Introduction It is a matter of fact, that these points are not always estimated objectively. Who knows for sure at the beginning of a project how much programming efforts will have to be made for realizing the application? In most cases, this can only be rated afterwards which means, too late.

DIMM-PC/MD Product Manual Hardware-Installation 6. HARDWARE-INSTALLATION ATTENTION: Please FIRST disconnect your DIMM-PC System from any power supply! The Modem Cards are delivered with settings adjusted to the IRQ5 and to I/O address 3E8h. If those configuration positions are already attributed to other cards, then the hardware settings for the DIMM-PC/Modem will have to be changed.
DIMM-PC/MD Product Manual Hardware-Installation Definition of the Hardware-Interrupts and of the I/O-Address The definition of the Hardware-Interrupts and the I/O addresses is performed by means of the DIP-switches located in the middle of the card ( see the picture below).
DIMM-PC/MD Product Manual Software Specification 7. SOFTWARE SPECIFICATION DIMM-PC/MD For controlling the modem select a suitable COM Port address and IRQ. The Modem appears at the ISA Bus (DIMM-IO Bus) as device with UART 16550 compliant register set according the specified settings.
