221034 Macrolink RS-232 4 Port Serial Line Conditioning Module

The Macrolink MVCP 4 / 8 / 16-Port Multi-Protocol Synchronous/Asynchronous Serial Communications Processor is a sophisticated, high-speed, microprocessor based controller configured with 8 or 16 independent synchronous/asynchronous serial communications channels. Each channel supports serial data rates up to 2Mbps. Status, data movement and detection, port arbitration and selection, and protocols are processed on-board, minimizing driver calls and host intervention while maximizing overall systems throughput.

The MVCP is designed to allow for the uninterrupted transfer of data, from a single character to a large contiguous block of characters, bi-directionally between the VMEbus and the serial lines. The MVCP handles all character processing, flow control, status decoding and interpretation, and error handling. The MVCP supports baud rates from 75 bps to 2Mbps on all 16 ports, with an aggregate throughput of 15Mbps.

The MVCP features and functional parameters are soft-selectable via a command line providing the user with greater flexibility to alter configurations without removing the controller from the system. These alterations may be done on a line-by-line or split line basis.

A single slot, 6U Eurocard module, the MVCP features socketed, 4-line serial interface modules. Up to 4 different interfaces can be configured on each controller. Current interfaces include RS-232, RS-422, RS-485, MIL-STD-188 and buffered TTL. Base memory is 1MB of 12ns SRAM which can be expanded to 4MBs.

Serial line connections are made via one or two 100-pin, high-density front panel connectors, with each connector supporting 8 ports. Supporting 12 signals per channel, each line features full modem control. Any unused or unwanted signals, on any line, or split line, may be masked. A full complement of 16 ports is also available via the P2 VMEbus connector.
