*Default is GND. This figure
only applies when cable has
been customised to output
+5V. The range is
dependent on the USB port
that the USB-RS232-WE is
connected to
**Default is GND. This
figure only applies when
cable has been customised
to output +3.3V.
***Only applies when
POWER output is customised
to +5V or+3.3V
Must be less that 2.5mA
