Description
The product detailed here includes part numbers 779651-01, 779651-04, 779651-06, and 779651-07, which fall under the GPIB category. The model in question is the GPIB-120B, designed to be fully compatible with both IEEE 488.1 and IEEE 488.2 standards. Its primary function serves as a GPIB Bus Expander/Isolator, which is essential for expanding the capabilities of GPIB systems.
This unit supports a maximum of 28 devices, providing a substantial increase in the number of devices that can be connected. For each unit added to the system, an additional 14 devices can be supported, enhancing the system’s scalability. It offers an isolation voltage of up to 2,500 VDC (non-continuous), ensuring the safety and integrity of data and devices connected to the bus.
Regarding data transfer, the GPIB-120B supports both Buffered and Unbuffered (default) modes, catering to different operational requirements and optimizing performance based on the specific needs. The product is equipped with multiple data lines, specifically DIO1, DIO2, DIO3, DIO4, DIO5, DIO6, DIO7, and DIO8, which facilitate efficient data transmission across the GPIB network. Moreover, it features 3 hardware handshake lines, which are crucial for ensuring reliable data transfer and communication between devices.
