Power output

The

+VO

pin can output up to 10 mA maximum. Use this terminal to power external devices or circuitry. Power

output connections are available on the SCSI connector and header connectors J4 and J5.

Caution! The

+VO

(+5V) terminal is an output. Do not connect to an external power supply or you may

damage the device and possibly the computer.

USB power

The maximum current that can be drawn by the device is 500 mA. This maximum applies to most personal
computers and self-powered USB hubs. Bus-powered hubs and notebook computers may limit the maximum
available output current to 100 mA. If the current requirement of the device exceeds the current available from
the computer, connect to a self-powered hub or power the computer with an external power adapter.
