Sealevel Systems, Inc. Announces Eight Port PCI Multi-Interface Serial I/O Adapter

August 7, 2003

Sealevel Systems, Inc. announces the ULTRA COMM+8.PCI, a multi-interface, eight-port, Universal Bus compatible PCI adapter. Offering eight field-selectable RS-232/422/485 channels, the ULTRA COMM+8.PCI delivers ultimate flexibility for expanding serial communications in a variety of test and monitoring, control, and point-of-sale applications.

The ULTRA COMM+8.PCI supports standard PC data rates and boasts a top speed of 921.6K bps. The board is designed using the XR16C864 UART, which provides a 128-byte FIFO, eight times larger than boards designed with 16C550 compatible parts. The larger buffers allow error-free operation even in high-speed applications. In RS-485 mode the ULTRA COMM+8.PCI offers automatic control of the RS-485 driver enable for trouble free network master arbitration. Additionally, the ULTRA COMM+8.PCI allows RS-485 network termination, critical to robust multi-drop communication, to be selectively added to the circuit via DIP-switches.

The ULTRA COMM+8.PCI also features Universal Bus (3.3V and 5.0V) as required by PCISIG specifications 2.3, allowing compatibility with both legacy and new computer systems.

The ULTRA COMM+8.PCI ships with Sealevel SeaCOM suite of Windows 95/98/ME/NT/2000/XP drivers. Sealevel also includes WinSSD, a full-featured diagnostic application, providing powerful testing and diagnostic capabilities. Use WinSSD for BERT (Bit Error Rate Testing), throughput monitoring, loopback tests, and transmit test pattern messages.

In addition to Windows drivers and utilities, SeaCOM includes drivers, utilities, application notes, and technical details to simplify installations in DOS, QNX, and LINUX.

Like all Sealevel products, the ULTRA COMM+8.PCI carries a lifetime warranty.
