PCL-858 8端口高速RS-232通讯卡 Main Features 8个独立的RS-232串行端口 传输速率可达921.6 Kbps 独立I/O地址,4个串口使用单独或共享的IRQ 多个IRQ可供选择:3, 4, 5, 6, 7, 9, 10, 11, 12 或 15 支持浪涌保护:3000 VDC (PCL-858B/858+) 数据表(PDF) 技术资料下载 产品介绍 PCL-858通讯卡提供8个RS-232串行端口,每个端口可使用板上的跳线单独进行配置。PCL-858A和PCL-858B通讯卡分别使用了2个16C 554UART芯片,能够确保更加**的I/O通讯。PCL-858通讯卡全部8个端口都支持自动寻址。所有通道均可共享同一个中断(IRQ),中断状态寄存器可以用来分辨中断源。当卡上产生中断时,中断状态寄存器(向量地址)会指出该中断来自哪个端口。共享中断可以设置为较常用的(扩展)AT中断。它能简化编程、加快中断处理并为其它设备空出中断资源。 Specifications PCL-858A-AE PCL-858B-AE communicationInterfaces CAN - - Current Loop - - RS-232 V V RS-422 - - RS-485 - - Display Ports 8 8 Network Cable Connector Type Optional Optional Protection Isolation - - Surge - - 订货信息 产品描述 PCL-858A-AE 8-port High-speed RS-232 Communication Card PCL-858B-AE 8-port High-speed RS-232 Communication Card 附件 产品描述 OPT8AP-AE 8-Port RS-232 ConnectionBox/Female DB25 Connect OPT8BP-AE CIRCUIT MODULE, 8 port RS-232(DTE) ConnectionBox W/(M)DB25 CONN.
