Interworld Electronics has released the ACB-MP4/PCI multi-port synchronous serial communications card from Sealevel Systems. Critical military, aerospace, and commercial applications often use synchronous communication when high-speed data transfer is required. Unlike asynchronous communication which frames each character, synchronous protocols only use one control set to frame a frequently large block of data, resulting in increased throughput.
The Sealevel ACB-MP4/PCI is a four-port PCI bus RS-232/422/485 synchronous serial interface card. Designed using the popular Zilog Z85230 Enhanced Serial Communication Controller (ESCC), the board is an ideal solution for applications that require multiple channels of robust synchronous communications.
For maximum flexibility, each of the ACB-MP4/PCIís serial ports can be individually configured for RS-232, RS-422, or RS-485 communications. In RS-232 mode, all common modem control signals are implemented for compatibility with a wide range of peripherals. Each port includes an independent digital phase lock loop (DPLL) for synchronization timing allowing the board to support data rates up to 128K bps in burst mode. Installing the ACB-MP4/PCI is easy with the included fan-out cable, which terminates the onboard 120-pin high-density Molex connector to four DB-25M connectors. Terminal blocks, adapter cables, and other helpful accessories are available to facilitate rapid installation.
The ACB-MP4/PCI features universal bus (3.3V and 5V) compatibility with both new and legacy computer systems. Software support, critical for successful synchronous communication development, is provided through Sealevelís SeaMAC V4 driver.
Sealevel synchronous serial products are engineered with strict attention to timing and other important considerations to achieve the most reliable, high-speed communication possible.
