Description
The GPIB-SCSI-A is a model developed by National Instruments that functions as a GPIB SCSI Controller. It is designed to control up to 14 GPIB instruments and up to 7 SCSI devices simultaneously. The controller boasts a variety of part numbers including 776569-01, 776569-02, 776569-03, 776569-04, 776569-05, and 776569-06, catering to a wide range of applications and requirements.
The device operates in two primary control modes, SCSI(S) and GPIB(G), offering flexibility in managing different types of devices. It supports asynchronous data transfer through the SCSI port, ensuring efficient handling of data. The controller is capable of performing all IEEE-488.2 functions including acting as a Talker, Listener, and Controller, making it highly versatile.
One of the key features of the GPIB-SCSI-A is its software selectable SCSI addresses, which simplifies the configuration process for users. When it comes to data transfer rates, the device does not disappoint. It offers a maximum transfer rate of 1.0 Mbytes/s for SCSI/GPIB read operations into the buffer, and 800 kbytes/s for reads from the buffer. For straight-through transfers without buffering, the rate stands at 600 kbytes/s.
This controller is designed to operate within a wide voltage range of 120-240 VAC, making it suitable for various power supplies. It also comes equipped with a substantial 256 kbytes of input RAM buffer to enhance performance. The maximum current requirement for the device is 90 mA at 120 VAC, ensuring it remains energy efficient.
For connectivity, the GPIB-SCSI-A features a 24 pin IEEE-488 GPIB connector, along with two 50-pin SCSI shielded I/O connectors, providing ample options for connecting with different instruments and devices. This combination of features and specifications makes the GPIB-SCSI-A a powerful and flexible solution for controlling GPIB and SCSI devices.
