Introduction
DIMM-PC® Concept
DIMM-PC® modules are very small, embedded computer boards that embed directly on an application-
specific baseboard, using industry-standard SO-DIMM sockets.
JUMPtec offers two types of DIMM-PC® modules:
®CPU modules, available with 80386, 80486, and 80586 processors, are fully PC/AT
compatible and come with a substantial amount of onboard I/O.
®I/O modules extend the functionality of DIMM-PC® systems by allowing additional
I/Os and peripherals.
DIMM-PC®/COM1
The DIMM-PC®/COM1 is a DIMM-PC® I/O module with two serial ports. You can configure the serial ports
to supplement the serial ports found on the DIMM-PC® CPU module, which appear as COM3 and COM4.

Serial Ports
The information in this section explains the hardware and software used by the two serial ports on the
DIMM-PC®/COM1 module.
Software Installation
Before using the serial ports, initialize the registers on the SMSC I/O controller on the DIMM-PC®/COM1
module. JUMPtec provides a utility called DIO1I111.exe to assist you.
The utility initializes the serial ports of the DIMM-PC®/COM1 module to use I/O addresses 3E8 and 2E8,
and IRQs 10 and 11 respectively.
To initialize the SMC, add the DIO1I111.exe utility to the autoexec.bat file in your system before any
program that needs to access the serial ports of the DIMM-PC®/COM1.
For non-DOS operating systems, the source code for DIO1I111.exe is provided in Appendix D. You can
use the code to generate a suitable configuration utility for the specific OS in use.
Serial Port Design Example
In the schematic below, Serial Port 3 (COM3) performs as an RS232 interface. Serial Port 4 (COM4)
performs as an RS484 interface.
