PCM-3614 (ADVANTECH)

The PCM-3614 is a PC/104-compatible module with four individually configurable RS-422/485 ports. It works with PC/104 CPU modules to extend additional RS-422/485 ports. The PCM-3614 also features lots of functions such as high transmission speed 921.6 kbps, independent/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-3614 especially suitable for multitasking environments. The PCM-3614 comes with a 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 configuration utility provides functions such as self-diagnostics and performance analysis for easy troubleshooting and debugging. The PCM-3614 provides versatile function settings to meet users' needs. These function settings include Standard/Enhance mode, Independent/Shared IRQ mode and Speed mode. Standard/Enhance mode setting helps the user use base address more flexible. Especially in Enhance mode, different base addresses can be set according to the application. In Shared IRQ mode, all ports of interrupt can be specified to one. This solves the problem of IRQ insufficiency within the embedded system. In Speed mode, the PCM-3614 allows transmission rate up to 921.6 kbps, improving the overall performance of the system.
