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.
