Description
Quatech RS-422/485 UPCI boards
completely meet the PCI 2.3 specification for Universal
connectivity and Low Profile boards, as well as all other
aspects of the specification so that you can be certain that
every Quatech Universal PCI board will function properly and
perform reliably in your system. Serial port connections are
made via an onboard DB-9 female port for single port models, and
via the included cables providing two DB-9 female connectors for
two port boards.
The new Low Profile PCI
footprint was designed to provide greater flexibility for
embedded systems, thin-clients, and desktop and server
environments. The boards are mechanically similar to standard
PCI boards, but use a shorter board and a different mounting
bracket. They are designed to fit into systems as low as 3.350"
without using riser cards. The boards are built on 32-bit
addressing, and can be used in standard PCI backplanes or with
specialized Low Profile PCI brackets. Quatech's RS-422/485
boards are built using the smallest (MD1) Low Profile board
specification, which allows them to be used in even the smallest
size systems without riser cards.
PCI 2.3 requires that all
plug-in cards support 3.3V signaling. However, many systems
still use 5V signaling. To accommodate both system types,
Quatech Low Profile boards also use a Universal PCI connector
compatible with both 3.3V and 5V signaling. This means that they
can be used with current equipment, and will not need to be
replaced as systems are upgraded. It also means that a single
serial board solution can be used across a diverse network
comprised of many different types of computer.
Each port on the board can be
configured as either RS-422 or RS-485 for full or half-duplex
communication. It is implemented with an automatic RS-422/485
transmitter enable/disable function that permits the hardware
itself to regulate data flow by only driving lines while
actively transmitting--providing increased speed and convenience
over the older software controlled method.
