More from the Manufacturer

The I/O8+ is a high performance, RISC- based, intelligent, low maintenance, multi-port I/O serial card for PCI based host machines.

It is designed for integration into server-based serial communications applications, and is ideally suited to environments where the IT infrastructure requires the support of multiple operating systems, such as Unix and Windows. The I/O8+ is most frequently used in applications requiring the connection of point of sale equipment such as cash tills and barcode readers, multi-user terminal systems using "dumb" terminals or thin client architectures, and automated teller machines.

This PCI bus 8-port serial board, with a fan-out (octopus) cable, configures 8 COM ports on the faster PCI bus, at data rates up to 115.2 kbps. It is an extremely dependable communication solution for ISPs or any type of RAS system that does not deal with an overwhelming amount of traffic. Each port includes integrated 16-byte FIFO buffer with software-configurable Tx/Rx triggers.

All eight ports share one PCI bus IRQ, even when accessed simultaneously, and thus saves valuable resources for other expansion cards. The first four serial ports have all of the standard serial signals, while the the last four serial ports do not include the Ring Indicator (RI) input. With easy plug-and-play installation, the Lava Octopus-550 automatically selects the next available IRQ and COM address; just plug it in and go!

USB to Serial Server providing 8 RS422/485 serial ports. Data transfer rates up to 921,600 baud rates and the 128 byte deep transmit and 384 byte receive FIFOS, coupled with 1Mbit line drivers deliver uncompromising performance on your laptop/PC.

Drivers for Windows 32 bit and 64 bit Operating Systems including Windows XP, Server 2003, Vista, Server 2008, Windows 7 and Windows 8 with additional drivers for both Mac OS X and Linux.
