|
The National Instruments GPIB-232CV-A is a GPIB-to-RS232 protocol converter that transparently converts data between the two ports without control codes or special commands. The NI GPIB-232CV-A also increases the efficiency of the interface system by isolating a slow device from the faster port using its built-in DMA controller and 256 KB RAM buffer. You can use the GPIB-232CV-A with virtually all PCs.The GPIB-232CV-A links either a GPIB controller to an instrument with an RS232 port or a GPIB device to a computer through the computer serial port. For example, the GPIB-232CV-A can interface a GPIB device, such as an IEEE 488 spectrum analyzer, to a computer with an RS232 port; or it can connect an RS232 device, such as a printer or plotter, to a GPIB network. Data transfers in either direction are possible at all times.
- Built-in DMA controller for high-speed GPIB transfers into buffer memory
- 8 RS232 data transfer rates up to 38.4 kb/s; hardware handshaking and the XON/XOFF protocols prevent data loss
- Switch-selectable interface parameters include IEEE 488 address, transfer rate, parity, stop bits, word length, and termination mode
- Built-in 256 KB RAM data buffer
- Special SRQ-ON-EMPTY feature for maximum GPIB performance
- NAT4882 ASIC
