SCSI Terminal Servers

by Digi International


Connect Devices the Easy Way!

The SCSI terminal server provides 8 local serial ports that require no complex network overhead. The ports, which are simple to install and configure, attach externally to the SCSI bus of a Unix or Windows NT system. The RS-232 ports can be used for connecting devices such as terminals, modems, and printers. All SCSI terminal, servers work with Unix systems from Sun, Hewlett-Packard DEC/Compaq, and silicon graphics, as well as with systems running Windows NT.

Efficiency and Expandability

The SCSI Terminal Server attaches externally via the standard SCSI system bus, a single card slot. A SCSI-1 switch and two SCSI-2 connectors are located on the back of eac unit. The unit can thus be easily daisy-chained to other SCSI Terminal Servers and a wide variety of SCSI peripherals.

Ease of Use

Unlike conventional terminal servers that must use Telnet and Rlogin to create pseudo-ports, the SCSI Terminal Server provides real serial ports that appear as local TTY's under Unix and as native COM ports under Windows NT. This makes the SCSI Terminal Server simple to install and configure, without the problems of complex network protocols. The simple instruction guide and automated procedures save you valuable time.

Performance

The SCSI Terminal Server supports speeds up to 115 or 230 Kbps. The intelligent design allows this performance to be achieved efficiently, with minimal impact on the SCSI bus even during peak loads. A simple packetizing protocol allows multiple lines to be serviced with each SCSI transaction, minimizing bus-loading and decreasing CPU overhead.

Device Drivers

Operating system drivers for Unix and Windows NT are provided at no extra charge with each unit. They are available on CD-ROM or may be downloaded from the Digi Web site. The drivers install automatically and provide several useful utility programs.
