The OMG-COMM4-LPCI-DB25 
Low Profile PCI serial interface 
provides four RS-232 serial ports, 
each capable of data rates to
460.8K bps. Each RS-232 port 
implements all modem control 
signals for maximum compatibility 
with a wide range of peripherals. 
The board is MD1 Low Profile 
and Universal Bus (3.3 V and 5 V) 
compatible and utilizes a 16C864 
UART to provide 128-byte Tx/Rx 
FIFOs for maximum reliability in 
data intensive applications. 
The board ships with a 36" cable 
that terminates to four DB25M 
connectors. If you need DB9 
connectors, order the 
OMG-COMM4-LPCI-DB9 which 
includes a cable that terminates 
to four DB9M connectors.
