Four-port card enhances serial communications

The ACB-MP+4.PCI is a four-port PCIbus RS232 synchronous serial interface.

Sealevel Systems announces the ACB-MP+4.PCI, a four-port PCIbus RS232 synchronous serial interface.

Designed using the popular Zilog Z85230 enhanced serial communication controller (ESCC), the board is an ideal solution for military, satellite, radar, banking and other applications that require robust synchronous communications.

For maximum flexibility, each of the ACB-MP+4.PCI's serial ports can be individually configured for RS232, RS422 or RS485 communications.

In RS232 mode, all common modem control signals are implemented for compatibility with a wide range of peripherals.

A digital phase lock loop (DPLL) is included on each port, and the board supports datarates up to 128Kbit/s in burst mode.

For easy implementation, a fan-out cable is included that terminates the onboard 120-pin high-density Molex connector to four DB-25M connectors.

Terminal blocks, adapter cables other helpful accessories are available to facilitate rapid installation.

The ACB-MP+4.PCI features Universal Bus (3.3 and 5V) for compatibility with both new and legacy computer systems.

Software support, critical for successful synchronous communication development, is provided through Sealevel's SeaMAC v4 driver.

HDLC/SDLC protocols are supported as well as certain configurations of monosync, bisync and raw modes.

The ACB-MP+4.PCI, part number 5402, is priced at $799 in low volume quantities and is available from stock.

Like all Sealevel I/O products, the board includes a lifetime warranty.
