PMC with Eight Asynchronous Serial Channels with FIFOs Features • PMC with eight RS-232 or RS-422 (order option) asynchronous serial channels • I/O via front-or back-panel (P4) connectors • Data rates to 460.8 kb/s (RS-422) or 115.2 kb/s (RS-232) • ESD protection • 128-byte FIFOs for receive and transmit on each channel • Comprehensive interrupts • 5V signaling • Windows NT, VxWorks, and Linux (kernel 2.6.0) driver support PMC-OCTPRO expands eight high-performance asynchronous RS-232/422 serial channels to a PCI Mezzanine Card (PMC). The PMC provides high channel density for serial I/O and data communications applications requiring a large number of serial channels in a restricted space. Two versions are available: the PMCOCTPRO-232 configures all serial channels for EIA-232 communications; and the PMCOCTPRO-422 configures all serial channels for EIA-422 communications. The PMC-OCTPRO features two quad UARTs with 128 bytes of transmit FIFO and 128 bytes of receive FIFO per channel. Data rates of up to 460.8 kbaud are supported for RS- 422, and up to 115.2 kbaud for RS-232 communications. The serial signals for each channel are routed to a 68-pin connector on the front-panel, as well as the PMC back-panel (P4) I/O connector. All signals are ESD-protected up to ±15 kV, according to IEC 1000.4.2 specifications. Socketed resistor networks are provided on the PMC-OCTPRO-422 for customization of EIA-422 termination. A breakout cable and a 68-pin terminal block are available for convenient signal access. These are recommended for prototype development. Baud rate is software configurable from 50 bps to the maximum rate via the on-board programmable baud rate generator. An empty oscillator side is also available on-board for custom baud rate generation. Interrupts are fully supported per channel, with four programmable transmit/receive FIFO interrupt trigger levels. In addition, programmable bit length, parity and stop bits are provided to support all asynchronous protocols. The cards are compliant with the standard PMC specification IEEE P1386.1. Asynchronous serial drivers are available for popular operating systems including Windows NT®, VxWorks® and Linux® kernel 2.6.0.
