### About DataFire SYNC/570

#### Introduction

The DataFire SYNC/570 family of adapters provides high performance synchronous communications in two-port and four-port models for ISA or PCI bus compatible systems. SYNC/570 adapters provide integrated remote LAN connectivity for major operating systems including Novell NetWare and Windows NT.

The PCI models offer a Universal Interface Bus (UIB) capable of supporting a different interface on each port. The UIB automatically configures the electrical interface of a port based on the type of Digi cable connected to the port. That is, you can select an interface type for a port just by connecting the appropriate cable between the adapter and the peripheral device. You can use any combination of interface types to connect up to two peripherals to the two-port version, or up to four peripherals to the four-port version.
