Macrolink MVC Sierra 8-Port Asynchronous Serial Commux VME / VME64 Module

  • Mix RS-232/ 422/ 485 and MIL-STD-188
  • 8 or 16 ports
  • 64-Byte Deep FIFOs
  • Interrupt Processing and Pacing Engine


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.

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.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
