RS-232↔IEEE 488 INTERFACE CONVERTER

EUROPEAN UNION DECLARATION OF CONFORMITY

To maintain safety, emission, and immunity standards of this declaration, the following conditions must be met.

•Serial and IEEE cables must have a braided shield connected circumferentially to their connectors’ metal shells.

•All cable screw locks must be tightened at both ends of the cable.

•The host computer must be properly grounded.

•Some inaccuracy is to be expected when I/O leads are exposed to RF fields or transients.

•The operator must observe all safety cautions and operating conditions specified in the documentation for all hardware used.

•The host computer, peripheral equipment, power sources, and expansion hardware must be CE compliant.

•All power must be off to the device and externally connected equipment before internal access to the device is permitted.

•An external power supply is provided with this product. Its input is 105 to 125 VAC or 210 to 250 VAC, 50-60 Hz, 10 VA maximum power draw. Its 9-VDC output connects to the power input of the unit (marked 10VDC MAX @ 500 mA).

•The RS-232/422 terminal is meant to be connected only to devices with serial-communications-level signals. The IEEE 488 terminal is meant to be used only with non-isolated IEEE 488 systems. The common mode voltage (cable shell to earth) must be zero.

•Terminal Installation Category for CE Compliance is Category 1.

•Operating environment for CE compliance is: Indoor use at altitudes below 2000 m, 0 to 40°C, 80% maximum RH up to 31°C decreasing linearly 4%RH/°C to 40°C.

•Regarding DC power input: Please note that the power input is marked 10VDC MAX @ 600 mA. This is just something to check; check your equipment’s power input labels for “600 mA” (or even 500 mA).
