SIO-104
PC/104
RS-232 Serial Interface Module
The 3551
PC/104 serial interface provides one
RS-232 port
capable of data rates to 460.8K bps.
The board
implements all modem control signals
for maximum
compatibility with a wide range of
peripherals.
The 3551 utilizes a 16C850 UART to
provide
128-byte Tx/Rx FIFOs for maximum
reliability in
data intensive applications. Ordering
options allow
the choice of UARTs for custom
baud rates and
9-bit protocols. Sealevel's
SeaCOM
software utilities make installation and
operation
easy.
ULTRA
SIO-104
PC/104
RS-422/485 Serial Interface Module
The 3550
PC/104 serial interface provides one
serial port
configurable for RS-422 or RS-485.
The board is
capable of data rates to 460.8K bps
and
automatically handles RS-485 transmitter
enable/disable. The 3550 utilizes a 16C850 UART
to provide
128-byte Tx/Rx FIFOs for maximum
reliability in
data intensive applications. Ordering
options allow
the choice of UARTs for custom
baud rates and
9-bit protocols. Sealevel's
SeaCOM
software utilities make installation and
operation
easy.
SIO.104+2.PCI
PC/104
RS-232/422/485 Serial Interface Module
The 3502
PC/104 serial interface provides two
serial ports,
each individually configurable for RS-
232, RS-422,
or RS-485. The board is capable of
data rates to
460.8K bps and automatically
handles RS-485
transmitter enable/disable. The
3502 utilizes
16C850 UARTs to provide 128-byte
Tx/Rx FIFOs
for maximum reliability in data
intensive
applications. Ordering options allow the
choice of
UARTs for custom baud rates and 9-bit
protocols.

C4-104.ULTRA
PC/104
RS-232/422/485 Serial Interface Module
The 3540 is the
first PC/104 serial interface
module to
provide four software-selectable RS-
232/422/485
ports. RS-232, RS-422, or RS-485
mode may be
selected independently via
software command for each
of the four ports,
eliminating the need for
setting jumpers or DIP
switches. The board is
designed using the
XR16C864 UART, which provides a
128-byte
FIFO, 8 times larger than boards
designed with
16C550 compatible parts. The
larger buffers allow
error free operation even
in high-speed
applications. In RS-485 mode the
C4-104.ULTRA
offers automatic control of the
RS-485 driver
enable for trouble free network
master arbitration. Additionally, the
C4-104.ULTRA
allows RS-485 network termination, critical to robust
multi-drop
communication,
to be selectively added to the circuit via a simple software
command.
