4894B Enhanced GPIB to Serial Interface
An enhanced bidirectional IEEE-488.2/GPIB to serial interface that can be used to adapt devices with RS-232 and RS-485 (RS-422) serial interfaces to the GPIB Bus. A 256 Kbyte RAM buffers up to 252,000 characters and frees the computer for other tasks while the 4894B transparently transfers data to or from the serial device when in the G mode. The 4894B's high speed DMA handshake transfers data at rates > 600Kbytes/sec to minimizes GPIB bus data transfer time. The 4894B's ability to run at any rate from 50 to 115,200 baud and in full or half-duplex mode makes it the ideal interface for driving modems, plotters, PLCs, RS-485 networks and other serial devices from the GPIB Bus.
