PMC422-LAM D2 串行I/O通道集成到单板计算机

【产品详情】

PMC-422是一种灵活的解决方案，用于将多个串行I/O通道集成到单板计算机(SBC)、VMEbus或CPCI系统上。高效地将8个串行通道打包到单个PMC上，有效地利用了可用的PMC站点。每个串行端口由一个独立的UART实现，具有独立的可编程波特率。一对端口中的每个端口都有独立的可编程线路驱动器，可设置任何最流行的信号类型:RS232、RS422、RS485(带端接或非端接选项的全双工和半双工)。信号特征由板载DIP开关设置。根据所用的具体晶振，每个串行波特率分别编程为150位/秒至6.2 Mb/秒。此外，还提供一个带8路通用输入的16位通用定时器/计数器。

【英文介绍】

The PMC-422 is a flexible solution for integrating multiple serial I/O channels onto a single board computer (SBC), VMEbus, or CPCI system. Efficiently package 8 serial channels onto a single PMC, effectively utilizing available PMC sites. Each serial port is implemented by a separate UART with an independent programmable baud rate. Each port in the pair has its own programmable line driver that can be set to any of the most popular signal types :RS232, RS422, RS485(full duplex and half duplex with terminated or unterminated options). The signal characteristics are set by the onboard DIP switch. Depending on the specific crystal used, each serial baud rate is programmed from 150 bit/s to 6.2 Mb/ s. In addition, a 16-bit universal timer/counter with 8 universal inputs is provided.

Four RS232 ports can be accessed via the front RJ45 connector

With the PMC input/Output module (PIM) PIM422, all ports are accessible on the rear input/output J4

Eight high-performance 16C550 UARTs with 64-byte RX/RX FIFO for each channel
