The PMC-3210-2F provides up to four synchronous or asynchronous full duplex serial ports, based on the Zilog Z85230 Enhanced Serial Communications Controller (ESCC). Two Z85230 ESCCs are used to implement four serial ports factory configured for either RS-232-C or RS-422. A related product, the PMC-3211, includes support for two dedicated DMA channels for each serial port. Each serial channel has an independent baud rate generator. A 16 MHz oscillator is used to provide standard asynchronous baud rates. Baud rate is software configurable from 50 bps to 125 Kbps, via the on-board programmable baud rate generator. In addition, programmable bit length, parity and stop bits are provided to support all asynchronous protocols. The module is compliant with standard PMC specifications IEEE P1386.1. The PMC-3210 is a direct replacement for the SciTech SciCom PMCs.
