PCM-3618 User Manual 2
1.1 Introduction
The PCM-3618 is a PC/104-compatible module with eight individually configurable
RS-422/485 ports. It works with PC/104 CPU modules to extend additional RS-2422/
485 ports. The PCM-3618 also features lots of functions such as high transmission
speed of 921.6 kbps, shared IRQ and more. It also provides high-performance
16C550 UART communication chip with 16-byte FIFO to reduce CPU load. This
makes the PCM-3618 especially suitable for multitasking environments.
The PCM-3618 comes with Windows 95/98/NT/ME configuration utility (Windows
2000/XP utility will soon be ready and allowed to download through our Web site).
The Windows con-figuration utility provides self-diagnostics and performance analy-
sis function for easy troubleshooting and debugging.
The PCM-3618 provides versatile function settings to meet users needs. These func-
tion settings include Shared IRQ mode setting and Speed mode setting. In Shared
IRQ set-ting, all of the eight ports of interrupt can be specified to one. This solves
problems of IRQ insufficiency within the embed-ded system. In Speed setting, the
PCM-3618 allows trans-mission rate up to 921.6 kbps. It improves the performance
of the system.
