Description
The GPIB SCSI Controller, identified by part numbers 776569-01 through 776569-06, falls under the category of GPIB and is designated as model GPIB-SCSI-A. This product is crafted by National Instruments and is engineered to manage up to 14 GPIB instruments and 7 SCSI devices. It offers modes of control through SCSI(S) and GPIB(G), ensuring a versatile usage scenario.
The controller supports asynchronous data transfer at the SCSI port, enhancing its functionality. It is equipped with IEEE-488.2 functions that enable it to act as a Talker, Listener, and Controller on the GPIB port, expanding its utility in various settings. Furthermore, the SCSI addresses are software selectable, providing flexibility in configuration.
One of the remarkable features of this controller is its data transfer capability. It boasts a maximum transfer rate of 1.0 Mbytes/s for SCSI/GPIB read into the buffer. Additionally, transfer rates for SCSI and GPIB reads from the buffer stand at 800 kbytes/s, while straight-through transfer rates for SCSI read/GPIB write are at 600 kbytes/s, ensuring efficient data handling.
The GPIB SCSI Controller operates within input voltage options of 120-240 VAC, accommodating a broad range of power supplies. It features an input RAM buffer of 256 kbytes/s and has a maximum current requirement of 90 mA at 120 VAC, making it a power-efficient device. For connectivity, it is equipped with a standard 24 pin IEEE-488 GPIB connector and two 50-pin SCSI shielded I/O connectors, facilitating easy and secure connections.
