OVERVIEW
Whether your industrial applications include oscilloscopes,
meters, plotters, printers, or other industrial equipment,
Black Box has the converter you need.
Imagine being able to control an industrial device from
your RS-232 PC. With the converter, you can attach an RS-232
device to an IEEE 488 device. The distance between the
converter and the IEEE 488 device can be up to 4000 feet
(1219.2 m). The distance between the RS-232 device and the
converter can be up to 65.6 feet (20 m). (See the diagram
pictured above.)
Interconnecting IEEE 488 and serial devices is easy with the
232 ↔488 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 because it runs at a wide range of speeds—from
110 bps to 57.6 kbps—it’s flexible for your application.
The converter’s dynamically allocated 32K buffer is there
when and where you need it. It will store data from whichever
port is active. Because 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’s 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
in the unit and turn on the power. The lights on the front
panel blink once to indicate proper operation. A steady light
indicates a problem area, except for the power light, which
always stays on.
You can run RS-232 or RS-422, so you don’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 adapts your old plotter to the serial communications port
of your PC.
The converter comes with an external wallmount power
supply (9 VDC) that plugs into the back of the unit.
NOTE: This unit is compatible with any IEEE 488 device except tape
drives, hard drives, or HP 2500, HP 2600, or HP 2900 printers.
