Black Box 232<->488 Converter parallel/serial adapter

Interconnecting IEEE-488 and serial devices is a cinch with this Interface Converter. The device can operate in either of two modes. In controller mode, it enables an RS-232 device to control an IEEE-488 device, such as a printer or plotter. In peripheral mode, it can transfer data from an IEEE-488 controller to a serial device. And the Converter is flexible, since it runs at a wide range of speeds. The Converter's dynamically allocated memory buffer is there when and where you need it. It will store data from whichever port is active. Since no specific buffer is allocated to each port, no buffer space is wasted and incoming data has access to storage when it needs it. The Converter is transparent to data format, so it will work with spreadsheets such as Lotus or CAD programs such as AutoCAD. A self-testing feature checks the microprocessor and program each time you power on. All you have to do is plug the unit in and turn the power on. The lights on the front panel will blink once to indicate proper operation. A steady light will indicate a problem area, except for the power light, which is always steady. You can run RS-232 or RS-422, so you won't need another converter to work with your RS-422 equipment. And even if you have an older HP 74xx or 75xx plotter, the unit will adapt your old plotter to the serial communications port of your PC.
