C.
Controls:
Power switch (external), and IEEE parameter switches (internal).
Indicators:
LED indicators for IEEE TALK, LISTEN, SRQ, ERROR, and POWER.
Power:
An external power supply is provided with the Digital488: Input is 105-125 VAC,
or 210-250 VAC; 50/60 Hz, 10 VA maximum. The external power supply 9 VDC output
is to be connected to the Digital488 power input marked: 10 VDC MAX @ 500 mA.
WARNING
Do not use this interface outdoors. The interface is intended for indoor use only.
Outdoor conditions could result in equipment failure, bodily injury, or death.
CAUTION
Do not connect AC power line directly to the Digital488. Direct AC connection will
damage equipment.
