该TPMC866是一个标准的单宽 32 位 PMC 模块,具有 8 个异步串行接口通道,具有前置 I/O 和后置 I/O。
TPMC866-10R 提供 8 通道 RS232 接口,支持每个通道的接收数据 (RxD)、传输数据 (TxD)、准备发送 (RTS)、清除发送 (CTS) 和 GND。此外,串行通道 1 和串行通道 2 提供数据集就绪 (DSR)、数据终端就绪 (DTR)、数据载波检测 (DCD) 和振铃检测指示器 (RI)。
TPMC866-11R 支持 8 通道 RS422 接口,并通过差分发射器和接收器提供 RS422 信号电平。每个串行通道提供发送数据 (TxD +/-)、接收数据 (RxD +/-) 和 GND。接收器信号终端(RxD+和RxD-之间为120欧姆)在每通道的TPMC866上提供。
TPMC866-10R/-11R 的每个通道都有一个 64 字节的发送 FIFO 和一个 64 字节的接收 FIFO,以显著降低向发射器和接收器提供数据以及从发送器和接收器获取数据所需的开销。FIFO触发电平是可编程的。
对于所有模块,波特率均可单独编程,每通道最高可达 460.8 Kbaud。所有通道都同时使用PCI中断INTA,但为了快速检测中断源,TPMC866-xxR提供了一个特殊的中断状态寄存器。接收器和发射器具有静电放电 (ESD) 保护。
所有TPMC866模块均提供扩展温度范围的 TPMC866-xxR-ET 版本。
提供针对不同操作系统的软件支持 (TPMC866-SW-xx)。

【英文介绍】
Standard single-width 32-bit PMC module
8-channel RS232 and/or RS422 ports
Asynchronous serial interface (up to 460.8Kbps)
Provides hardware handshakes and full modem support
64 byte FIFO
Front panel I/O (HD50 SCSI-2 connector) and P14 I/O
The TPMC866 is a standard single-width 32-bit PMC module with 8 asynchronous serial interface channels with both front and rear I/O.
The TPMC866-10R provides an 8-channel RS232 interface that supports received data (RxD), Transmitted data (TxD), Ready to send (RTS), Clear Send (CTS), and GND for each channel. In addition, serial channels 1 and 2 provide data set readiness (DSR), Data Terminal Readiness (DTR), data carrier detection (DCD), and ringing detection indicators (RI).
The TPMC866-11R supports an 8-channel RS422 interface and provides RS422 signal levels via a differential transmitter and receiver. Each serial channel provides send data (TxD +/-), receive data (RxD +/-), and GND. Receiver signal terminals (120 ohms between RxD+ and RxD-) are provided on TPMC866 per channel.
Each channel of the TPMC866-10R/-11R has a 64-byte transmit FIFO and a 64-byte receive FIFO to significantly reduce the overhead required to provide data to the transmitter and receiver and to obtain data from the transmitter and receiver. The FIFO trigger level is programmable.
For all modules, the baud rate can be individually programmed up to 460.8 Kbaud per channel. All channels use PCI interrupt INTA at the same time, but for quick detection of interrupt sources, TPMC866-xxR provides a special interrupt status register. The receiver and transmitter have electrostatic discharge (ESD) protection.
All TPMC866 modules are available in the TPMC866-XXR-ET version with extended temperature range.
Provides software support for different operating systems (TPMC866-SW-xx).
