SCSIserver ^TM
The preferred choice for serial port connectivity

Using the industry standard SCSI bus, available on virtually all computers sold today, SCSIserver requires no backplane slots and provides for migration to other hardware platforms. SCSIserver eliminates protocol overhead and the slow response time associated with ethernet terminal servers. Interrupt overhead and the flow-control burden placed on the processor by most embedded serial controllers is a thing of the past with SCSIserver localized flow control.

ABLE designed an application layer daemon that shuttles data between the pseudo-tty driver and the SCSI disk driver of whatever flavor UNIX that you might be running. This type of portability avoids the problems associated with kernel drivers such as recompiling and sometimes not working when new OS versions are released. System priority and timing for port scanning are in full control of the system manager. See some interesting sites in the Application Notes.

SC16	16 serial ports with full modem control on RJ45 connectors, supporting baud rates to 115Kbaud and both soft & hard flow control localized to the SCSIserver removing the burden from the host computer. All ports have extended protocol capability and can be customized. All this for less than $100 per port.
SC16e	The subassembly from the above unit is an industry standard 5 1/4 inch disk form factor for embedded applications or for saving money by providing your own external box. Under $90 per port.
SC04	This unit provides one parallel port and 3 serial (1 RJ11 and 2 RJ45 ports with full modem control).
SC12	Same as the SC04 with an additional 8 serial ports (RJ11 or RJ45 - your choice).
SC20	Same as the SC04 with an additional 16 serial ports (RJ11 or RJ45 - your choice).

SCSImaster

Using the same SCSIserver technology and software, the SCSImaster connects up to 128 serial ports for terminals, modems and printers on a SINGLE scsi address. This allows up to 896 ports to be connected to a single scsi bus. SCSIserver provides a single twisted pair high speed SDLC port for connection of MuxMaster work area concentrators and EASYway extended networking products. See SCSImaster, MuxMaster and EASYway applications for examples of the many possibilities.

SC04M

This SCSImaster unit connects one parallel port and provides for a single twisted pair distribution system to connect up to 128 serial ports on a single SCSI ID (896 ports per SCSI bus) using MuxMaster ® work area concentrators. The SC04M is also compatible with the EASYway ^TM line of network solutions for applications requiring redundancy, port management, fail-over, load balancing or additional security or remote connectivity.
