When it comes to adding serial ports, Nothing Beats SCSI.
Configuring today's multiuser systems and client-server networks is becoming increasingly complex. It can also be very expensive. Central Data's innovative scsiTerminal Servers can help. They save you time by reducing the hassles normally associated with serial connectivity. They will also handle your most demanding applications by delivering fast, reliable performance.
Because scsiTerminal Servers connect to the SCSI bus, they eliminate any complex network configurations. Unlike SBus, PCI, or EISA multiport boards, scsiTerminal Servers do not use any card slots. Serial ports can be added without ever opening your workstation cabinet. And the fewer slots you need, the more money you can save -- up to thousands of dollars on future workstation purchases. With scsiTerminal Servers you can standardize on a single solution across an entire range of UNIX platforms (Sun, HP, IBM, DEC, and Silicon Graphics).
Don't delay. Call 800-482-0315. Evaluate a scsiTerminal Server today with our 30-day money-back guarantee. See for yourself how Central Data's scsiTerminal Servers can simplify your communications requirements.

Central Data's new scsiModem Server makes it easier than ever to add modems to your UNIX workstations and servers. It integrates 8 or 16 PCMCIA fax/modems in a single chassis, saving space and eliminating the cabling mess of stand-alone modems and power supplies.
Interfacing via SCSI makes the scsiModem Server simple to set-up and administer. Each modem port is a native tty port, which means there are no complex network configurations, no Ethernet bottlenecks, and no system card slots consumed. The SCSI-based ports also reduce CPU overhead, and deliver a much lower cost-per-port than network-based solutions.
The scsiModem Server is ideal for dial in/dial out applications such as field sales or small branch office communications, online information services, Internet access, and other situations where modem pools are required. SLIP and PPP are both supported on your host. scsiModem Servers connect to UNIX systems from Sun, HP, IBM, DEC, and Silicon Graphics.
CPU: 40MHz 80C186. RAM: 256K at zero wait-states. EPROM: 128K FLASH at zero wait-states. SCSI: 53C94 SCSI bus controller, single-ended interface. 5MB/sec transfer rate. PCMCIA: 8 (SM-5008) or 16 (SM-5016) Type II slots, compatible with 16550 based PCMCIA modems. Hot-swappable in pairs. Power: Internal 5V, 40W supply. 1.25W max. per modem. Size: 2.3" (5.9cm) high, 17.6" (45.7cm) wide, 7.6" (19.7cm) deep.
If your application demands the highest in system availability, rely on Central Data's Redundant scsiTerminal Server. It's the ideal solution when you can't afford system downtime. Eight fully- redundant serial ports and two independent power supplies provide the protection you need. And like all our scsiTerminal Servers, it connects to the UNIX host(s) via SCSI, without using any internal card slots.
CPU: Each scsiTerminal Server has 14.75MHz 80C188 processor. Serial: 8 redundant RS-232 ports, RJ-45 connectors. A-B Switches: High-reliability "form C" comm relays, switched by host software using either of two control ports. Manual switch overrides available. Power fail switch-over mode. SCSI: Two single-ended SCSI buses, NS8490 SCSI controller. 1.2MB/sec transfer rate. Size: 16.4" (41.6 cm) wide, 5.9" (14.9 cm) deep, 1.7" (4.3 cm) high.
High-Performance Design
After years of design effort, Central Data has produced device drivers for all the leading UNIX workstation families. Each driver is highly-optimized for SCSI-based communications. They're designed to limit SCSI transactions so that no more than 8% of SCSI bandwidth is used. A special packetizing protocol allows multiple lines to be serviced with each transaction. This provides excellent echo-back response, while reducing the number of interrupts to minimize workstation overhead. The result is improved performance, especially when compared to traditional serial boards, that can chew up ten times as much overhead.
