1.2.21.2.2 PowerPower
The UDAS unit normally uses power from the host computer via the USB cable. Power can also be
obtained from an external power supply that is available (See Appendix B, Accessories). When the
UDAS unit is connected to a power source, the computer controls the power. The unit does not
have a power switch. There is an LED labeled PWR located on the front panel that indicates
power to the unit, regardless of its source.
The USB specification imposes strict requirements on power usage. If an external power supply is
used, up to 200 mA at +5 VDC is available to external termination circuits (available at pin-26
and pin-48 of the unit’s 50-pin I/O connector).
See section 1.3, Software Support and Accessories or Appendix B, Accessories for the part numbers
of the available Power Adapters. If the power is supplied from the PC through the USB port, care
must be taken to limit the load from the external termination panel to less than 20 mA.
