| Macrolink’s MVCS Sierra
Asynchronous Serial I/O Commux is an advanced high-speed controller for VMEbus D32
applications. Available with 8 or 16 asynchronous serial lines, it supports individual
line rates up to 1.5 Mbps, and an aggregate throughput of 48Mbps. Independent baud rates
for each port and a wide variety of I/O interfaces allows you to tailor the MVCS for your
needs. High Performance
The MVCS combines innovative hardware design with an
Industry Standard 16550 Serial I/O application interface. We use the latest
generation UARTs with 64-byte internal FIFOs. Deeper FIFOs mean less interrupt overhead
and less load on your host. FIFO status bits are combined and readable in one single
32-bit access, as 16-bits of read status and 16-bits of write status.
UART interrupts are combined and presented at paced
intervals to the VMEbus, dramatically reducing interrupt handling overhead by the
system's Host CPU card. Optional extended FIFOs are available to lower VMEbus
bandwidth requirements, supporting rates over 30 MB/s.
Easy to Use
Device driver support is available for popular UNIX and
Real-Time Operating Systems. The Sierra is the ideal solution for new high-speed Async
designs, and brings improved performance to legacy systems.
Mixed Electrical Interfaces
Our 4-port serial line conditioning modules allow each MVCS
to handle multiple line disciplines. A single MVCS can be configured with any mix of
RS-232, RS-422, RS-485, MIL-STD-188C and buffered TTL in 4-line groups. Up to 4 different
serial line conditioning modules can be installed with up to 12 signals per line for full
modem control. Serial line connections are made via two 100-pin, high-density front panel
connectors. An optional P2 transition module is also available.
Macrolink has designed and manufactured performance
oriented communications, mass storage, memory and related subsystem products since 1978
and understands your demand for reliability and support. Macrolink products are covered by
one of the most comprehensive warranties in the industry. All products are temperature
cycled and burned-in to eliminate failures in the field. Computer testing checks virtually
every parameter and aspect of the products.
