Getting Started

Connect Multiple

Instruments

If you are connecting more than one instrument to a computer, use a USB hub.
The USB port or hub must supply more than 450 mA at 5 VDC for power
instrument operation. Read more about USB power requirements. (See page 1,

Computer, System, and USB Requirements

.)

LED Indicator

There is a green LED located below the trigger out (TO) connector on the
instrument. This LED indicates instrument status as follows:

Dim green and steady: This shows power is being supplied to the instrument
but that the instrument has not yet been recognized by the computer.

Bright green and steady: This is the state for normal operation and shows that
power is being supplied to the instrument and that the instrument has been
recognized.

Bright green and blinking: This state shows that the instrument is not getting
enough current from the USB port. This usually means that the USB port
is not a high current USB 2.0 port.

Bright green and blinks a few times: This state is activated when you have
requested the software to identify the instrument. This is useful when you have
multiple instruments connected at once. (See page 10,
